Solved: Unable to boot XP - Unmountable Boot Volume

Q: Solved: Unable to boot XP - Unmountable Boot Volume

When I start the machine (XP Pro), it wonít boot in any mode. Going via F2 I can get to boot from CD but I donít have an XP recovery CD for the machine as it was an OEM with pre-installed XP (Tried a friendís XP Pro Recovery disc but it just gets me to Unmountable Boot Volume)

Have run Ubuntu (which works) and have recovered my files but would like to recover the XP OS if possible. Is there any way I can use Ubuntu to recover (as the HDD is obviously ok). Sorry havenít got any info re the machine apart from its a Toshiba U400.

Any thoughts would be really appreciated

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

-Using Windows XP on a Dell Dimention 8300 desktop.-

About a week ago, I attempted to start up my computer, and to my dismay, I ended up with the blue screen of death with an error that was something like

unmountable_boot_volume EDx0000000 0x0000006 0x0000000

(I'm currently typing from memory on my ipod so please forgive me if I'm a bit vague) Anyway, I've tried everything I can think of. I'm unable to run chkdsk as it brings me directly to partitions, and I really don't want to re-format because my data and backups of things are very precious to me. Is there anything I can do?
Also yes I did use the search function before posting this and nothing helped

A:Unmountable Boot Volume error, unable to fix, need help

I believe when you run chkdsk - you have to choose which partition you would like it to check/fix.

Also, have you tried a repair install?

I have this older Compaq desktop I got out I haven't used in awhile. I am trying to remove all my files from old computers.

Well I started it up and it gives me the infamous Blue Screen of Death (BSOD) and says "Unmountable Boot Volume." The computer didn't do the BSOD when it was in use.

I did a Google search and searched on TechGuy and found the procedure to boot from the Windows XP Install disc to run the recovery mode. I checked the BIOS and saw that it was set to boot into the CD-Rom drive. So I inserted the install disc but I can't get the computer to run in the recovery mode.

Here is what happens everytime I start it;
Press any key to boot - I usually press Enter but it goes to the next screen.
We apologize for the inconvenience but windows did not start successfully. - It gives me options to different boot into Windows but for some reason I can't move up or down on my keyboard. It boots into Windows normally.
Windows XP start screen appears
BSOD - Unmountable_Boot_Volume

What do I need to do to make the computer boot from the install disc?

I greatly appreciate any help or advice.

A:Solved: Can't Boot into Recovery Mode to Fix Unmountable Boot Volume

Either there is something wrong with the XP installation CD, or something wrong with the CD drive, or you didn't hit the "any key" quickly enough. For the last one make sure it starts to read the CD after you hit Enter and before it tries to boot normally. For the first one see if you can boot the CD on another computer (you don't have to do anything with it except to see if it boots).

I have the UNMOUNTABLE BOOT VOLUME error. But, for me, it's not as simple as popping in the XP startup disk, because the HP I have was upgraded by a computer shop (so I didn't get that disk).

Anyway, I think I have a way to fix it. I can connect the hard drive from the computer that is presenting the problem to this computer, which will give me access to the files that are on it, which means that I could manually fix the file that is causing the boot volume to be unmountable. (Whatever that means.)

My question to you kind folks is: how do I go about this? Once the hard drive is connected, what file do I need to repair, and how do I repair it? Any help will be very much appreciated.

I'm in a bit of a pickle here, as trying to boot my computer normally (with or without safe mode) gives me the aforementioned boot volume error. After finally tracking down my Windows CD (it was on the shelf, who would've thought?)

Last week given HP Desktop with the Unmountable Boot Volume error. Ran chkdsk from the Recovery console. It ran through and then on reboot worked OK. After making sure the problem didn't happen again I gave it back. Owner hooked it up and same error message. I got it back today, ran chkdsk and it booted up to Windows. Just finished running the WD disk diagnostics which it passed.

Probably will replace the IDE cable before giving it back, but I would hate to get a call that the Unmountable Boot Volume error has returned. The only other information is that both times the error showed up were after the system was moved. Once from the original to a new owner and then from me back to new owner. Also of interest (not sure it means anything) is the problem popped up both times the new owner turned the system on for the first time (after she bought it and after I gave it back) . I guess maybe I should carry it around the house a few times before returning it. I know this would usually get posted in the XP forum, but I guess I'm looking for a hardware explanation. Advice appreciated.

i am using xp home on an hp pc (therefore no recovery discs). after a blackout, i got the unmountable boot volume blue screen. i have searched the forums, talked to hp and got the same answers. the problem is none of them work.

i cannot restart in safe mode or last good configuration. a friend made the 6 xp set up floppy disks for me and theat gets me into the repair and once there, chkdsk does not work. i have tried both /p and /r and both times i get the message:
autochk.exe could not be located in either the startup directory or the cdrom drive.
type the full path <including drive letter> for the location of autochk.exe

i tried fixboot and it says it fixes something, but on restart i am stuck back in the blue screen.

one of the hp guys suggested i install an earlier version of windows, so i can backup files before a full system restore. i found my old office 97 cdrom, but i don't know how to install it with a whacked out system.

it just occurred to me that i am dumb. office is not an operating system and i know that. i have a version of xp pro. will that work? if so, how do i install?

I have a Sony PCG-7134M laptop. When I try to start Vista normally I get a BSOD saying UNMOUNTABLE_BOOT_VOLUME. It will not start in safe mode and I do not have a repair disk or installation disk. What can I do?

A:[SOLVED] Unmountable Boot Volume

UNMOUNTABLE_BOOT_VOLUME BSOD's usually point to a failing hard drive or corrupt filesystem.

--My first recommendation would be to attempt to back up any important data by carefully removing the drive and connecting it to a working PC to see if you can access the data

If you can boot to safe mode (probably not) or a Windows OS disk and access the command prompt (cmd) in the repair options you can run a disk check which can repair a corrupt filesystem/ bad sectors, blocks, and clusters.

The command for that is: chkdsk /x/f/b/r (if Windows XP omit the "b" switch)

Let this run through. Once it is finished attempt to boot to Windows. If you successfully boot to Windows back up any important data immediately. And run a hard drive diagnostic on the drive.

HDD Diagnostic

1. Download Seatools and Easy Burner (if you don't currently have a program to burn .iso files to a CD) from the link in my signature

2. Install Easy Burner

3. Burn Seatools for Dos to a CD

4. Insert the CD to the CD drive on the problem PC, restart the PC and boot from the CD (please post if you need help booting to disk)

5. Once Seatools boots run a Long test on the Hard drive (found under "Basic Tests" at top left)

And I only see that BSOD when I disable automatic restart. The stop code is 0x000000ED (0x86403130,0xc000009c,0x00000000,0x00000000). I get the blue screen (momentarily) on all of the other F8 options.

When I boot using the Vista disk I get the msg 'Windows is loading files...', then I get what looks like the bottom part of the XP splash screen - the little bar with the green dots moving from left to right (was that part of the Vista start, as well?), then eventually the screen goes black..... and stays that way. Although after about 30 seconds the mouse pointer does show up - and its moveable. And the keyboard lights up properly on Caps Lock and Num Lock. But nothing else.

I did try booting off an old XP disk, and it did take me to a place where I could delete the partition.

Should I try that, and then try the Vista disk again, or should I just go ahead and install XP (although I would have that pesky product key to deal with)?

I somehow feel that if I could only get to a C: prompt I could do a fixboot

A:Vista will not boot - Unmountable Boot Volume - Won't Boot from Disk Either

and I'm not talking about a good answer. ANY response at all would have been appreciated.

My original post, titled Vista will not boot - Unmountable Boot Volume - Won't Boot from Disk Either seemed like it would be the kind of posting that would have elicited some response - Can't boot normally, in safe mode, or last good configuration. AND, can't boot from a genuine Microsoft Vista Home Basic disk.

But nothing.....

So I inserted an old HP Windows XP OS CD into the machine, and booted to the recovery center, where I selected to install XP. I formatted the drive, and then ejected the disk. I then put the Vista disk in, and booted from it.

Presto, it worked. This time it actually took me to the Vista Repair / Install page.

I deleted the partition, entered the product key and re installed Vista.

It is now working beautifully.

Thanks for your help.

I'm using an Asus AM2-MX mobo that has 4 sata connectors and I have a Seagate sata drive I'm running XP from. I found out that when it froze the HD had gone offline.

Anyway, now I'm trying to get my XP install back again. Now I've disconnected all other drives and am running chkdsk /r out of Recovery Console but it hasn't worked so so far. ALso ran fixboot with no results. Will run fixmbr it chkdsk /r doesn't work. The repair function in RC doesn't even list an XP install to repair either. If anyone has any ideas on this please reply.

My friend's PC is getting the BSOD: unmountable_boot_volume. I've read alot of good information about BSOD fixes on TSG, but I can't seem to get close to fixing this machine (or even a good start).

I'm working with a Dell Dimension 4600.
On startup, I'm getting the above BSOD and there has not been any hardware changes since the machine was purchased (which I thought was related to the error code).
I am unable to boot in safe mode (it stops at /agp.dll line). I have also tried booting from the other options: command prompt, VGA mode, last known good, etc....
In the boot menu, the cd-rom is listed as NOT INSTALLED. The USB devices are listed as uninstalled as well.
I do not have a spare hdd to swap for testing or a floppy boot disk.

Does anyone have any suggestions as to what else I can try? I am very willing to reinstall XP Pro if I can boot to it.

Hi, I've tried everything with this laptop to no avail, and though maybe someone here might know how to fix my problem.

Well, it started yesterday when I booted up and got the "Windows did not start successfully" message. No matter what option I picked (safe mode, start Windows normally etc.), it would go to the Windows logo and begin to load, and then quickly flash the BSOD and restart again, returning to the "Windows did not start successfully" message.

I then disabled automatic restart on system failure and this time the BSOD stayed on screen and told me that I had an "UNMOUNTABLE_BOOT_VOLUME" error. I looked around on the internet, and from what I read I decided to run Chkdsk from the Recovery Console.

This is where I am stuck. I have two "Recovery CD-ROMs" instead of the Windows XP CD, because the laptop came with Windows XP preloaded, and I figured that to get to the Recovery Console I should insert one and boot the laptop. I tried both, and nothing happened (it just loaded the "Windows did not start successfully" message again).

I then loaded the CD directly by hitting Esc on start up, but the only options that came up were 1. MS-DOSwith CD-ROM support, 2. Recover Windows XP to first partition only, 3. Recover Windows XP to entire HD, and 4. Recover Windows XP to entire HD with 2 partitions.

A:[SOLVED] Unmountable boot volume error, cannot load Windows XP disk

Hello Clare

You will have to borrow a proper (full) XP installation CD from someone.
Configure your PC to boot from CD if it isn't already set up that way. You may need to enter the BIOS to configure the PC to boot from the CD.
Set the boot order to
floppy (if present)
Hard disk

Start your PC with the XP Setup CD in the drive. When you see the "Press any key to boot from CD..." prompt, do so and let the CD-based boot process begin.

When the Recovery Console option is offered (Press R to start the Recovery Console), do so. You may be asked which Windows installation to enter, in which case type the number of the Windows installation you wish to work on (usually 1).

When prompted, enter the Administrator's password for that Windows installation. If you did not set a password just press ENTER

At the command prompt, type
chkdsk /r

"CHKDSK is checking the volume...

I left my computer for an hour to run the check and when I came back it was still at 0% and had shown no change. My hard drive is the default 160GB SATA drive that came with the computer.

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installationg, ask your hardware or software manufacturer for any windows updates you might need.

I bought  this used computer a couple weeks ago. It was working great. I have been adding my software, and using it just fine. I went to bed the other night, and when I woke up, I had a blue screen error that said it had encountered an error, and needed to restart. Since then, I have rebooted multiple times, and I get a few different errors, but never a full reboot.It will start like normal with the main screen that has bootup options. I have tried them all - boot menu, system recovery, diagnostics,Then it thinks for a LONG time. Eventually, it will give me an error and says it will restart for me. Most common error listed is Unmountable boot volume. One time, I got Attempted write to read only memory. I cannot get  to safe mode. I have tried F8 with no luck. I have seen one option to reset ioptions whihc includes enable safe mode, but that doesn't work.Sometimes I get the automatic repair which gives me advanced options. I pick troubleshoot, and I get reset this pc. It  tells me that the drive where windows is installed is locked. Unlock the drive and try again. No idea how to do that. So, then I tried advanced options.System restore - System restore could not find the offline boot volume. Please ensure it is currently accessible.System image recovery - An internal error occurred. The system could not find the path specified. (0x80070003)Startup repair - startup repair couldn't repair your pc. Log file D:\WINDOWS\System32\Logfiles\SrtTrail.txt.startup set... Read more

How to fix the ďUnmountable Boot VolumeĒ error.

I have a Gateway Laptop Model MX 6121 thatís quite a few years old (Iím not sure exactly but itís definitely more than 7 years old).
Recently I have encountered the error screen ďUnmountable Boot VolumeĒ that prevents me from booting my computer.
Iíve read numerous solutions and the closest Iíve come to solving the problem involved downloading a Windows XP ISO and creating a boot disk. I boot from the disk and once the program has finished loading I get a screen that says this:

The following list shows the existing partitions and unpartitioned space on this computer.

Use the UP and DOWN ARROW keys to select an item in the list.
To set up Windows XP on the selected item, press enter.
To create a partition in the unpartitioned space, press C.
To delete the selected partition, press D.

38155 MB Disk 0 at Id 0 bus 0 on atapi [MBR]
C: Partition1 [Unknown] 38146 MB <38146 MB free>
Unpartitioned Space 8 MB

I choose ďC:Ē and I hit enter. Then I get to a screen that says this:

An error occurred while Setup was updating partition information on:
38155 MB Disk 0 Id 0 on bus 0 on atapi [MBR].
Setup cannot continue. To quit Setup, press F3.

There are no other options so I press F3 and I get to one final screen:

Windows XP has not been installed on this computer. If there is a floppy disk in drive A:, remove it. To restart your computer press enter.

A:Unmountable Boot Volume

try the following if you have an xp disk

1. Insert your XP installation disc into disc drive and boot up your computer.
2. When you see a welcome screen, hit the R key on your keyboard. This will enter you into recovery mode with a DOS prompt.
3. Now type chkdsk /p and hit Enter. This will launch a utility which will check for errors on your hard drive.
4. After the process is done, type fixboot and hit Enter to repair any damaged boot files which may have become corrupted. When asked to say yes or no, type the Y key on your keyboard.
5. Type exit and press the Enter key to reboot your computer.

if that does not work, there are other suggestions in the post you made at cnet forums.

when i went to turn on laptop it came up
windows could not start because the following file is missing or corrupt
you can attempt to repair this file by starting windows setup using the originasl setup cd-ron (i dont have)

so tried f8 and safe mode with command prompt and all the other options also

windows could not start because the following file is missing or corrupt
you can attempt to repair this file by starting windows setup using the originasl setup cd-ron (i dont have)

what are my options.
i saw this on trademe http://www.trademe.co.nz/computers/software/other/auction-818316017.htm
would this help?
Its important i get some of my files back for work

how do i tell if hard drive has failed,would it tell me?

any help appreciated
have a great day

1. welcome to Tech Support Guy
2. Re the link and the repair disk - I cannot say if it would help but it is unnecessary to try at this time
3. GO here on another computer of course and make yourself the Windows XP Recovery Console disc
Please download ARCDC from http://www.artellos.com/ccount/click.php?id=5

Double click ARCDC.exe
Follow the dialog until you see 6 options. Please pick: Windows Professional SP2 & SP3
You will be prompted with a Terms of Use by Microsoft, please accept.
You will see a few dos screens flash by, this is normal.
Next you will be able to choose to add extra files. Select the Default Files.
The last window will allow you to burn the disk using BurnCDCC
Your ISO is located on your desktop.
It is an ISO, so must be made using either the inbuilt ISO burner or a simple straightforward free one such as Burn CDCC
Here is the download for that
When you have that made either using a one time boot key - it normally says on the post screen for boot menu press?
OR from post screen entering setup BIOS make CD first boot device
See if the computer will now boot from the Recovery Console - when you are asked for a password this refers to the System admin account password and not your usual USER account - often it is not set, so you simply leave it blank
If it does and after selecting the installation to repair
at the cmd prompt
chkdsk /p
P is a special chkdsk cmd used only in the RC an... Read more

I'm hoping that some of you hardware enthusiasts can shed some light on a problem I'm currently having with a rig.
The current situation is that while booting Windows XP Proffessional, the computer will go directly to blue screen before finishing booting, claiming

*** STOP: 0x000000ED (0x8239AB98, 0xc00000A3,0x00000000,0x00000000)

Upon closer inspection with the Safe Mode start, it seems to be hangin at Mup.sys, at least thats the last thing that pops up efore the BSOD.

I had a quick look on the Microsoft Knowledge Base for information about the problem and it seems that this type of problem is related to cahce writing on NTFS format drives, which would make sense. I wasnt around th last time the computer booted, but the way I understand it the computer was in-game, and froze and was almost immediatly restarted, which would explain if perhaps the cache had not fully cleared and then some crucial bootable data had been left there and not written back the hard drive.

For whatever reason windows is not automatically starting chkdisk when it boots to try and deal with the problem. On the Microsoft Knowledge Base, it says to use the WinXP cd to do a commandline restore from the boot cd. I tried this, but unfortunatly, I'm using 2 80gb dirves in stripping raid, and my raid controller disk doesnt seem to want to cooperate in WinXP start up.

The current situation is basically that i cant get to any... Read more

Try booting from the CD and try the recovery Console.
If that doesn't work, try the repair option on the CD.

Hey everyone. Okay so I am having this problem with my friend's computer. I was just suppose to clean it out for him and give it back but when I turned it on it gives me the splash screen and then, WHAM!! a blue screen saying "unmountable boot volume". I know for a fact he does not have the windows boot cd so is there a way I can get it to a floppy disk?

Also when I run the diagnostic, and I look at the green letters labeled A-D I see that the letter D is orange while the others are green. I would really like to get this problem fixed asap. if someone could help me, it would be greatly appreciated.

I have a pretty new Dell vostro laptop, with win 7, 64bit (home edition i think).
I'm on a trip, and i don't have the recovery disk.
i get the BSOD with the "unmountable boot volume" msg.
i googled it and found a lot of things i could do, most of them recommanded using the disk, which i don't have.
one of them said to press F8 and choose the repair your computer options, which i did and then a desktop looking window appeared with nothing on it, and then after about 25 mins a window poped asking which langues i want, i chose english (US) and then after another 10 mins this window showed, i chose command prompt, and started typing some of the stuff that people suggested:
chkdsk c: (with /p /r /f, alltogether and most of the possible combination)
the main thing i noticed is that nothing seemed to be wrong, with 0kb of bad sectors or something like that.
then i tried:
bootrec /ScanOS, it finshed the scan saying that, amount of windows something something was: 0
which i guess isn't good, then i did this:
bootrec /fixboot, it said very quickly somthing like: Done
and then i wrote this:
bootrec /fixmbr, and also very quickly wrote something like Done.
and then i wrote exit and restarted, and the same problem accured, as if i havn't done anything..

Thanks a lot in advance,

I hope someone can help with a couple of questions re: a dying laptop!

We have a couple of Toshiba laptops. One of them is an old Satellite Pro L20 which is running XP Pro. It has been getting slower and slower recently.

We've recently installed a new router in the house. The L20 is BG generation, and the router is N generation, so we bought a Linksys router that came with a USB wireless-N reciever. This came with some Linksys 'connection manager' software that worked to begin with, but then kept refusing to connect, saying that the USB receiver was incorrectly installed. After a week of this, off and on, I decided to uninstall the Linksys programme and revert to Windows own connection manager.

During the uninstall the laptop froze up. It wouldn't respond to CTL-ALT-DEL, and in the end I powered it off. And that's where my troubles began ...

At restart, it passes briefly through the Toshiba screen, hits the XP loading screen - and then bluescreens. The error message on the bluescreen is hard to read, because it is displayed only momentarily before cutting to the Start-Up options. The error message does definitely include the phrase 'Unmountable boot volume' however.

None of the 'Safe mode' start-up options gets me any further.
The restarting just keeps recycling round and round.

I've tried connecting to it directly with the other laptop [via LAN cable] and then I get an error message on the guest machine saying that the host machine's modem isn't wo... Read more

A:Unmountable boot volume

Not to worry - I've sorted this out.

If anyone else has a similar problem, this is what I did:

1. Went into BIOS [F2 on my machine, at start-up] and changed the Boot directory to start with USB, rather than HD.

2. Bought a 4GB USB stick.

3. Downloaded Slax: http://www.slax.org/

4. Extracted Slax to the USB.

5. Ran bootinst.bat on the USB. [Make sure it picks your USB drive as the source of the boot - if it doesn't, cancel]

6. This gave me a 'Live USB' with a simple Slax OS on it.

7. I plugged the USB into the laptop and rebooted.

8. I accessed my harddrive via the Slax OS on the E: drive and copied the files that I needed. Slax also allowed me to burn some DVDs so I recovered some music files that I'd figured would be too much hassle to recover.

9. Now I'm going to erase the hard drive and then run my recovery disk to reinstall Windows clean. If it works, it works. If it doesn't, I've lost no data.

Hey all,
I found this site when I was trying to troubleshoot this dreaded blue screen I have. Somebody had the same problem, and I tried the standard chkdsk functions to no avail. At 33% I too get the error:

"The volume appears to contain one of more unrecoverable problems.
153043220 kilobytes total disk space.
24858492 kilobytes are available.

4096 bytes in each allocation unit.
38260805 total allocation units on disk.
6214623 allocation units available on disk."

I'm running Windows XP on a pretty old Dell Dimension 8400 system.
I'm also running a 2 month old Macbook Pro.
I just went out and bought myself a new external Hard Drive. I tried booting straight from that and trying to install Windows on it and then trying to set my internal HD as a slave and at least recovering my files from it. When I go to install Windows, it tells me it cannot gain access to the disk. I'm using the Windows XP Dell Disc that came with my computer. Could it be that it's not installing Windows on my External because it wasn't installed by Dell?

So, you get a BSD when you boot your computer and the error is Unmountable Boot Volume? What OS and SP are you running by the way? Check to make sure the cables are plugged in, reseat them, but, if this is a recurring BSD, normally your disk is not bootable, and your OS can't read the boot sector. You can look here http://support.microsoft.com/kb/555302 to see if it helps.

I have always had my laptop in hibernate mode, unless; I was installing something or every few days for a reset. I am not much in to downloading, inface; the last item downloaded was an emergency response guide from the Government of Canada's website, so I think it would be clean and I even scanned it. After the restart days later it would boot up to a point just past the splash page for WinXP and then a blue screen flashed and it would restart the boot up process again. Eventually I was able to pause the screen through "F12" I believe. I located a WinXP installation/ boot CD and it is telling me I have to reboot. There are files I require for various things, pay, emergency response pre plans and school work that I am hoping can be recovered first. Is there anything I can do to recover and repair this without losing my items, I have heard of people being able to do it and that would be excellent if this can be done. One of the menu options before the blue screen is to start windows with that last known working settings or something to that effect. Is there anyone who can help?

My friends computer, Dell Dimension 3100 is now showing in the BSOD 'unmountable boot volume'. He has spoken with Dell, who say he needs to return the machine and have a new HDD fitted, which at this moment he cannot afford.
Are Dell right to say it needs a new HDD or can it be fixed using chkdsk etc. in DOS.
If he bought a new HDD (what would you recommend), would he also have to buy a new windows XP disk or can he use the disks that came with the computer.
Many thanks in anticipation of a helpful answer

If he can get hold of a windows xp disc, rather than a restore disk, boot from the cd (you may have to enter the bios to change the boot order) once everything has loaded enter the recovery console by pressing R. You will then be asked which windows installation to repair, usually "1" and an administrator password, hit return and you should get C:/.

Type chkdsk /r note the space after the k. This will then check your windows partition and repair any errors and in most cases will solve your problem. It could take an hour or so!
