BSOD Blue Screen of Death: UNMOUNTABLE_BOOT_VOLUME

Yesterday in the morning i was going to burn a cd with some podcasts that i hear on my car in my way to work, when the pc was booting i face it: the scary BSOD with the message "UNMOUNTABLE_BOOT_VOLUME".




Why me?, i started to think about what i have done to this occur, i checked my IDE cables, boot again and again (safe mode, last known... bla, bla) hoping to fix it alone but nothing works, so before kicking the pc or format it , i tried booting with a win XP cd and in the recovery console (pressing "R", then choosing "c:/windows", and finally entering the administrator password) i typed this:


1. chksdsk /r [enter] --> it takes a long time
2. chksdsk /p [enter]
3. fixboot c: [enter] -->if c: is where windows is installed
4. exit ->to reboot again

And it works, i got xp back again :P.

I had the same problem with a Compaq Presario 6000 Desktop PC.
That certainly did the trick!

Thanks.

Didn't work for me, It's driving me nuts and my XP Pro doesn't allow me to boot to the prompt to use chkdsk /r, I have since installed Linux and it works like a champ.

That's a good reason to move....

damn. the issue i am having is that I cannot type anything when it gives me the "Boot from CD :" prompt. is there any way around that?

Thank you so much for posting this. For two weeks I had been unable to boot my laptop, but because of your solution, I have now successfully been able to get it up and running again.

You are made of the most absolute win.

Does this fix for the UNMOUNTABLE_BOOT_VOLUME reformat your harddrive? Also will any windows home edition cd be suitable for this or does it need to be a recovery cd for your particular model?

carlos mafla said...

No, it doesn't reformat your drive. Any windows XP installation cd should do the job.
good luck

Thanks for the post; I was able to recover from this. I couldn't get in to windows directory, so I just ran dskchk on C:\ I got it breathing again.

Thanks!

My crash was deeper than that, when I ran the chkdsk command, it checked until about 34% an then this appeared: The volume appears to contain one or more unrecoverable problems.
Sad..

Diego said...

Same identical problem, same identical solution!!! (all the steps you suggested were absolutely perfect!)

Thx a lot m8!

man, this is an old post, but a great solution. Thank you so much, saved my ass!

tomp said...

EVEN WITH THE RECOVERY DISK IT WILL NOT GET TO THE THAT POINT WHERE I CAN REPAIR OR REFORMAT THE HARD IT JUST LOOKS LIKE WINDOWS IS LOADING AND THEN GOES TO THE BLUE SCREEN. IT THE GOES TO THE PAGE WITH DIFFERENT MODES TO START WITH---I'VE TRIED THEM ALL. WHAT'S NEXT, JUST REPLACE THE HARD DRIVE

Carlos said...

google the error number (that 0x0000XXX) that could give you a general idea of the problem, sometimes is a memory problem...

Anonymous said...

bad luck for me.. during chkdsk around 25% this line appeared "The volume appears to contain one or more unrecoverable problems." i had to reformat to solve the puzzle =(

Thank goodness!

I slept one night and left my computer to download some files on torrent. When I woke up, my pc kept rebooting over and over and always stopped at the windows bootscreen with a sudden flash of the BSOD. I disabled to caching and finally displaying the BSOD properly, "unmountable_boot_volume." I did the steps, ran ASR, chckdsk /r, chckdsk /p, fixboot, then exit, and re-enabled the cache/shadowing on bios. After that, my windows started working normally again. I almost lost hope and considered reformatting my pc, but you saved me. By the way, I'm running genuine Windows XP Home SP3, and used a pirated Windows XP Pro SP2 cd to boot up to ASR, so the info was right that it didn't matter what XP cd installer you had as long as it was bootable. Again, thank you so much! :D

I REALLY hope this works with my laptop. I have a good 2 hours of original recorded music that me and my bass player recorded that I simply cannot lose.

You do not need to separately run a chkdsk /p.

If you use /r, the /p is implied within the command ...

Big UPs, it worked for me too......

After 4 1/2 years from the original post, this fix worked for me also. Kudos to the original poster!! I would point out that the command is CHKDSK, not CHKSDSK as in original post (at least on my Dell Inspiron B120).
