UNMOUNTABLE_BOOT_VOLUME

Another Windows XP tip, from the dark corners of my own personal experience.

The problem: You turn on your computer, but Windows doesn’t start. All you get is a blue screen that says UNMOUNTABLE_BOOT_VOLUME. What, oh, what do you do?

The solution: Boot into the Recovery Console. For this you need your XP CD, and go through the motions like you’re going to reinstall Windows, but look for the Recovery Console option instead. The Recovery Console is a command-line interface with diagnostic and repair tools. Once you’re in the console, enter these three commands in turn:

chkdsk /r
chkdsk /p
fixboot

The first one can take half an hour or longer, the others zip by really quick. After that, reboot your computer, and you should be golden!

    How can you do this if you cant get past the blue screen to do anything…. tried everything to bypass it but i can’t

    What you have to do is boot from the Windows CD. You won’t get the blue screen, you’ll get the setup screen. And from there you can get into the Recovery Console, which is just a command line. That’s where you run those commands.

    I can’t get past the blue screen either? As I turn on the laptop I hit F8, I hit anything like safe mode command or not and It runs for 10 sec’s and then back to the blue screen. I start it up with the xp cd in it and it just does the same thing and I end up at the blue screen. Help please before I send it out and loose my 300 plus pics. Thanks, Rob.

    Ok, I have this problem, but when I use my windows xp cd to run windows setup and start the recovery console, I get a new stop error with a message about ntsf or something. So what do I do if I can’t even run the windows recovery console?

    I keep getting this error after reformatting on a failed SP2 attempt. I am trying to reinstall the original Windows XP disk but each time setup reboots the machine I get the error and the chkdsk /r chkdsk /p and fixboot commands won’t work–even after a total reformat.

    Thank you so much for that info!!! You really saved my butt. All the IBM help desk suggested was to replace the hard drive (and lose all the data). Thanks to your tip I can recover it all. Thanks again! And, yes, I did rattle the tip jar.

    Hello, I was wondering if there is a way to get a Windows XP disk, I have a brand new computer and a used one, unfortunately the used one is the broken one. I don’t have a disk for it.

    I’m getting the unmountable_boot_volume error, but it only comes on to my screen for a split second during startup, it then shuts down and restarts itself. I haven’t installed anything on my laptop recently- it was working perfectly an hour ago. I still need to try the disk. Has anyone had similar problems?

    This worked just fine… only one thing…
    when using fixboot…it tried to write to E:… since i was trying to fix C, I had to type “fixboot C:” A minor thing.. but can cause confusion to anyone not familiar with chkdsk parameters.

    Thanks so much for your help! :)

    In order to setup your computer to boot from the CD-rom, you’ll need to exit to the BIOS configuration screen, which can be done during the initial boot up sequence of your computer… it’ll check the memory and devices and such, and will print somewhere, “Press ‘DEL’ to enter BIOS setup.”, or something along this line. Do as it says, then go to BIOS setup or some such menu, and select boot sequence with the arrow keys and hit enter.

Do as it says and press a key before time expires… of course, making sure your Windows (XP or a similar version may be required) CD is in the drive. It’ll go through some initialization steps, then give you some options; you need to pick the Recovery Console (by pressing “R” when available) option. From here you can do as was previously posted, and type “HELP” any time you need a list of available commands.

    Thank you for the info. I had the same problem and tried a lot of things before trying your suggestions. I tried and it didn’t work, but allowed me to figure what was causing the problem. It was the cable and not the cable! I was using a removeable hard drive tray and it had a short section of 40 wire cable. I took the HD out of the tray and directly attached it to the 89 wire cable and my problem was solved. I would have never figured it out without your direction.

    I am using a Toshiba Laptop and i got this same problem of unmountable_boot_volume,.

    I used the steps u showed here .. for a moment i thought it works, but then, after reboot, the screen remains at the WinXP log in page.

    So i run the same step again, boot up using WinXP CD and enter recovery option. HOWEVER, this time round, it shows C:/windows instead of just C: in the earlier one. And also, this time round, i have to type in Administer Password, which i swear i did not set any.

    Fyi, Toshiba Laptop does not come with WinXP CD, they only provide a recovery disk which doesn’t give me any option to save my files. It’ll completely restore my laptop as new. So i used a different copy of WinXP disc, which i believe is SP1.

    How can i fix this problem without having to reformat or using the recovery CD? I can’t afford to lose my project files which i had been working on for 8 months already.

    Tried the WinXP recovery disk after the blue UNMOUNTABLE_BOOT_VOLUME error screen pops up. Managed to get as far as the menu with the options to Repair, Install or Not Install WinXP but my Toshiba V7010 switches my keyboard off so I can’t make a selection. I’ve tried plugging in a USB keyboard but it simply doesn’t recognise it. Is there any way around this?

I’m however, able to get into the recovery console (i think) with my recovery CD. the only difference is…before i get to type chkdsk /r or /p, i have to choose to log into either 1)miniNT or 2)i628…so i’m not really sure if this is the recovery console we’re talking about here. Prior to this screen i saw the “Welcome to set up” words and there was an option to press R. Appreciate if anyone could help me on this =)

    Thank you very much! I had this unmountable_boot_volume error. I ran Dell’s device tests for the hard drive and on the Read Test it failed with and msg: Block 19760676: Uncorrectable data error or media, same for the Verify Test. So I booted into the Recovery Console, executed the command chkdsk /r (corrected one or more errors and took about 45m), execute the chkdsk /p (took about 7 minutes), then I ran the fixboot (took about one minute), exited the Recovery Console and my PC booted right up, I really want to thank you guys, I thought I had lost my data (backing up as I write this) and I thought I was going to have to buy a new hard drive.

    Thank you thank you thank you!! Thanks Scott (if yu still read this) for starting the thread and giving the solution and thank you Dave for explaining how boot from the disc. I have a DELL X200 with an external CD-ROM and found it very difficult to boot from the CD. I will try to encorporate Dave’s advice with my own (in brackets) to help anyone else with a Dell laptop:

    In order to setup your computer to boot from the CD-rom, you’ll need to exit to the BIOS configuration screen, which can be done during the initial boot up sequence of your computer… it’ll check the memory and devices and such, and will print somewhere, “Press ‘DEL’ to enter BIOS setup.”, or something along this line. (I had to keep F10 pressed down when turning on to get to the BIOS screen, then arrow down to [Setup], Press ‘Enter’, arrow right to the ‘Boot’ menu) Do as it says, then go to BIOS setup or some such menu, and select boot sequence with the arrow keys and hit enter. Now, make sure your CD-rom is the first device on your boot sequence list (I had to put ‘External Device’ to the top not CD-ROM), then exit the menu, and exit the BIOS screen with SAVE (there should be a list of key commands, including save with exit listed somewhere there). Now restart your computer again, you should get the message “Press any key to boot from CD…” or along this lines. Do as it says and press a key before time expires… of course, making sure your Windows (XP or a similar version may be required) CD is in the drive. It’ll go through some initialization steps, then give you some options; you need to pick the Recovery Console (by pressing “R” when available) option. From here you can do as was previously posted, and type “HELP” any time you need a list of available commands.

    Also a word of warning. The first chdsk took over an hour and a half! Others about half an hour.

Last night i got pissed off at my mom for asking me too manny questions while playing world of warcraft and then i pushed the power switch to turn off the computer w/o going through the proper shutdown method. and this morning when i tried to turn it back on, i am gettting UNMOUNTABLE_BOOT_VOLUME. i’ve tried to reboot through windows xp startup disk to get to the console and i am gettting the error message that says CDR-001 failed…so i thought this error probably referred to the CD-ROM so i checked my cd-rom and it works fine. i also tried the scan disk method and it found 2 *.wdm files to fix. i rebooted the computer, and i am still getting UNMOUNTABLE_BOOT_VOLUME where it recycles itselfs. Also tried safe mode, safe mode with dos prompt, and etc, nothing works. so now i am just doing a surface scanning, it takes about 1hr40min to complete. I doubt this will fix though. I am waiting for gf to return me the windowxp startup, so that i can try other method to see if it works…more info to come…

    Hurray!!!! I finally got the WindowsXP startup CD from my gf. Initially, when i run using the 6 WindowsXP disketts, I got the CD–rom.sys error (4096) because my bios for some reason had set to boot to SCSII drive and not CD-ROM. So i corrected this and then using my bootable WindowsXP startup disk, going to Recovery Console and run Scott’s posted commands:
    1. chkdsk /r (aprox 45min, i have a 60g HD)
    2. chkdsk /p (5min)
    3. fixboot (5sec)
    Then reboot the PC and barabing baraboom, I got windows xp logon screen. I was very ecstatic after 8 hrs of fixing it. Now i can get back to play my World of Warcraft. Thank you Scott!

    FYI,

    Using the chkdsk /p option is not necessary if you use chkdsk /r. When you use /r it automatically assumes /p.
    You can find this info by looking at the help screen for the chkdsk commant by typing “chkdsk /?”

    Interesting to see others encountered this problem after switching off the computer after World of Warcfraft froze, as i did. I have done the chkdsk /r, and then get “the volume contains one or more unrecoverable problems”. fixboot doesnt fix it. If anyone figures out a solution please post it. Also everyone email blizzard to aware them of this problem so they can perhaps patch it before others join our fate.

    I’ve tried all the above and everything eventually comes back with unrecoverable errors. Chkdsk can back with volume “appears” to be in good condition … and suggested I use /p to force a check, which I did with the same ol problem “unrecoverable problems.”

    chkdsk finishes in about 15 seconds … 16% complete with unrecoverable problems message.

    I even tried to remove the hard drive, put it in an external usb case and connect to another PC to get the data off, but I can’t read the drive … however, when it is installed in the computer, it does start to boot to XP Pro and then I get the same dreaded blue screen, so I know it isn’t a complete hardware failure anyway.

    If anyone has some more suggestions, I’d really like to AT LEAST get my data off this drive.

    Hey guys. I’ve been researching and reading for two days now. I’ve read over this forum but i think I might be missing some info.

    I have a HP machine with a SATA drive. Have the unmountable_boot_volume error message and the continual reboot problem. I’ve tried the chkdsk /f, chkdsk /p, and fixboot problem. All these work without error messages but I still cannot boot into windows. Same problem, unmountable_boot_volume.

    Is there a solution to this I missed? Any help would be greatly appreciated. It’s my parents computer and they haven’t done any backups. As I’m sure with all of you, I hate to see my parents sad.

    P.S. The computer is new and the hard drive is not bad.

    Sat down for two days now. There wasn’t a solution to this problem. Microsoft, HP and Norton was not able to offer any solutions and stated that the data was lost. They all recommended rebuilding.

    I found this guy who lives in town and retired from San Francisco as a tech. He’s a freakin computer whiz and had hardware and software to rebuild the hard drive, sector by sector. It took him about eight hours to rebuild, sector by sector, but he saved every bit of information on the drive. All my programs work and all my information is there! HELL YAH!

    I just wanted to clear something up for some of you out there.

    When you receive this error, and look for help, a lot of people tell you to get to the Recovery Console. I’ve been reading through these posts, and there have been a few people saying that they tried the CD that came with the pc.

    THE CD THAT YOU NEED IS AN ORIGINAL (or however you want to come across it) WINDOWS XP INSTALL CD.

    Without this cdrom, you’re pretty much toast. The other alternative is use 6 floppies and get the driver utility from Microsoft’s site.

    When you “boot to cd,” you’re basically putting the WinXP install cdrom into the cd drive, and turning on the computer/rebooting. At some point, it will prompt you to “Press any key to boot from CD”. Do so. Afterwards, you’ll get a blue screen that loads the setup options. Let this finish doing what it needs to do, and you’ll be presented with 3 options. This is where you want to hit the R button.

    This will bring you into the recovery console. There are two scenarios at this point in time. First one being that you get a c:\ prompt right off the bat. If this happens, then great, run chkdsk /p, chkdsk /r, fixboot. You MIGHT have to choose which installation you would like to log in to, and need to provide an administrative password. Hope you remembered to store that little bit of information in a safe place!

    HTH the people who aren’t too sure about what’s going on with the whole “recovery console?” or “driver cd?” questions. Take care, and good luck.

I just turned system restore off the free up some disk space, then erased the many copies of my administrator files that had crept into C:\documents\ over the years, but forgot to save a new restore point before rebooting. Nothing is corrupt or over written. All that’s wrong is blocks 0 - 63 of my FAT are missing.

    Here’s a question…I have a friend’s laptop and he’s having the same problem with the unmountable_boot_volume. I just downloaded the startup files for winxp pro, and it says it takes 6 floppys to run them fully.

    Here’s the trick, he got the laptop as a hand-me-down and he didnt get the floppy drive with it. all it has is the CD-ROM drive, but he doesnt have the winxp pro recovery disk either. So the question is this….if i burn the winxp startup files onto a CD and set it up in the BIOS to boot off the ROM drive, will it work the same as it would if it were taking the files off 6 floppys?

    Hey, im having a problem that im sure many of you are having unlike some of you im far from computer savvy so i need some specific instructions, but anyways im on a dell inspiron b120 laptop, im actually on my brothers laptop because on mine i cant even get to my desktop, im haveing the unmountable_boot_volume blue screen and ive tried everything possible, ive tried going in through safe mode like it says but like every other way i get the blue screen at the windows loading screen, so i cant get to my desktop. i called dell tech. support and before i spend a bunch of money i would really like to fix this problem on my own, now i do not have the windows refresh cd or whatever it is that wipes everything and gives you back your desktop. I also called best buy as a last resort to get a diagnostic ran, but again i would like to get this fixed or attempt it on my own. But anyways i have windows xp if that helps but yea ive tried everything ive gone into bios and messed around but nothing seems to work so if you have any secrets or tricks please tell me, thank you,

    Hey
    Right so ive got the same stupid UNMOUNTABLE_BOOT_VOLUME blue screen. The pc won’t boot from my windows disc. Its not even doing that memory check thing where i push del to enter the bios setup thing. it just goes straight to that screen that gives me the options of safe mode, safe mode with networking, last known good configuration, start windows normally. Its pissing me off. like seriously. This pc is on its way out the window.
    I’m not an IT boff so if its possible give the answer in the simplest for possible :) thanks!

    You have to go in to the bios and tell it to look at the CD drive before it looks at the IDE drive…..you see, when you boot your system it looks for a device that it can boot with, now,. you have your bios set up to look at the IDE drive, so you want to change the values to make it boot up from the CD drive, so, right when you turn on the computer start gradually pressing the F2 or Del (those are the most probable bios setup entering buttons) and when you get to the bios you should see a part of the page that says “boot” just follow the instructions from the bottom on how to change the values and make sure the CD is number 1, then do the things suggested above………………..its funny, I just did it yesterday, I got the same stupid error and it worked, yay!!!…………………good luck, I hope I was a help.

    Sorry to bring up a dead topic.. Here goes. I have a Compaq Presario SR1250NX, P4 3.2 Ghz running XP on a 160 gig SATA harddrive.. I obtained an older drive.. The labeling calls it a 60 gig, but only 30 shows up viewing from my current XP. I had to disconnect my slave, which went to the CDROM. The primary IDE goes to the DVD-ROM, so I thought this would be ok. I just got my BIOS to read it, and I’m able to select it as a boot option, but it doesn’t load. It gives me some sort of error, causing me to reboot. I have an XP CD which I’m able to boot from. However, before the option to select recovery console or installation, it gives me two errors, each at random at any attempt. “File isapnp.sys is corrupted and could not be loaded.” The second is, file \i386\KDOM.DLL could not be loaded, error code 4096.”. I have my BIOS set up to automatic, but there are dip-switches on the back. Must these be correctly set to a specific, or the jumpers removed? Once more, I’m running a DVD-ROM to the master, and the harddrive as the slave. My current working harddrive is SATA, so it causes no interference and has nothing to do with this extra IDE drive. Thanks.

    I have experienced a similar problem with the blue screen and the UNMOUNTABLE_BOOT_VOLUME error message. After wasting a lot of time reinstalling XP several times with the same result, I finally figured out the reason for the error and how to work around it.

    I believe the problem ONLY happens when installing pre SP2 versions of Windows XP on hard disks LARGER than 128GB.

    The solution I found was to use the hard disk manufacturer’s disk manager program to fdisk & format a partition that is less than 128GB; I chose 40GB. Install XP in the usual manner and complete all the steps of setting up your user profiles. The next step (and this is CRUCIAL!) is to install Windows Service Pack 2 and to reboot the computer on completion.

    The last step is to create an extended partition from the unallocated space on the hard disk and set up logical drives. To do this follow the steps Start > Settings > Control Panel > Administrative Tools > Computer Management > Disk Management.

    Alternatively, if you didn’t want a second partition, you could use a third party application like Partition Magic, to resize your primary partition to the hard disk’s full size.

    If you follow these steps you should never see any of those UNMOUNTABLE_BOOT_VOLUME error screens again.

    Slightly different problem, mentioned once, but I had different results:

    Initial problem:

    Windows could not start because the following file is missing or corrupt:

    \system32\hal.dll.
    Please re-install a copy of the above file.

    I went to “recovery console”

    1. chkdsk /r (fully scanned no problem)
    2. chkdsk /p (fully scanned no problem)
    3. fixroot c:
    4. confirmed by typing “y”
    5. exit
    also did in reverse with “fixroot c:” first

    when reboot same error message *

    *Windows could not start because the following file is missing or corrupt:

    \system32\hal.dll.
    Please re-install a copy of the above file.*

    Anything else?

    sorry left out:

    did bootcfg /rebuild this message comes up:

    error: failed to successfully scan disks for windows installations. This error may be caused by a corrupt file system, which would prevent Bootcfg from successfully scanning. Use chkdsk to detect any disk errors.

    Ran scandisk and came up with “the volume appears to be in good condition and was not checked. Use /p if you want to check the volume anyway.

    ran chkdsk /p

    chkdsk has finished checking volume…

    seems to be no problems?!

    Any ideas?!?!

    My Dell Inspiron laptop locked up while I was online. When I restarted it, I got the blue screen on death. Fortunately, before I did anything drastic, I went to a friend’s computer and happened on your site. Booting my computer from the XP install CD, going to the Recovery Console and entering those three command lines did the trick. My laptop hard drive is whole again, and the problem was caused by one corrupted block out of 315 million. Thanks, and I’m glad I wrestled Dell Customer Support to the ground to get the OS install CD back when. It didn’t come with the computer, and Dell gave me a big song-and-dance about how I didn’t need it (or a print version of the Owner’s Manual, for that matter). But as I told them, having that info online doesn’t do a whole lot of good if your computer won’t even boot to get online. Thanks again. for this valuable information.

    Just a few things
    If you have a dell there is a chance you had media direct (or whatever) installed. In my case it was actually partitioned into E (C being my main drive, D being the cd drive). When i used the recovery console it used E: with no option of C:, but by deleting the partition (go through steps as if you were installing windows, afterward when partitions come up select it and push d). After this i didnt need to pick the drive nor enter the admin password.

    I had the exact same problem. Thinking it had something to do with world of warcraft as well. I did what Scott suggested in the original post with chkdsk /r and /p and foxboot. all Seemed to work fine until it said,

    Windows could not start because the following file is missing or corrupt:

    \system32\hal.dll.
    Please re-install a copy of the above file.*

    I went to the site you listed Scott and tried to repair / install windows over my current one. When it gets to the reboot stage when you have to remove the windows XP CD it hangs on “Boot from CD/DVD :” and nothing happens.

    Am about to try reinstall windows again on another partition, but something tells me thats going to cause me no end of dramas with 2 versions of windows running :(

    I got the Stop error blue screen.

    DRIVE 2: TSSTcorpDVD-ROM TS-H352C- Diagnostics not supported
    DRIVE 3: Philips DVD+/-RW DVD8631 - Diagnostics not supported.
    OK….After reading some stuff on line here, I went looking for my Operating Systems Disc….Well, low and behold…All Dell gave me is some paper disc that says: Your new computer does not require an operating system CD or drivers CDs. Instead, if you ever need to reinstall you software, use one of the following methods. They are: System restore and PC restore…..only problem is you access them via the icon on the desktop!!!!!
