Unmountable Boot Volume error

After installing windows on my mac ive tried toget into it again but a blue error screen appears with UNMOUNTABLEBOOTVOLUME. I cant seem to switch back to mac as i didnt have the latests service package i needed to install it anyway so i turned off nmy computer to see if i could switch back to mac but i cant and that error just comes up for windows. Any clues on how to fix the problem?

I am having similar issues, but I'm still working on the main reason for the problem. We are trying to install Windows XP from our network installation system using WinPE.
If I format the drive as GUID partition table XP crashes with the UNMOUNTABLEBOOTVOLUME error...pretty much sounds like the installer doesn't understand GUID even though it is an XP Professional Service Pack 2 install base.
If I format the drive as an MBR partition table XP will load fine, but then I have the issues where the OS and OS chooser screen don't see the Windows partition as a bootable partition, and then I have to use rEFIt to boot into Windows.
If I install Windows XP from the same CD that I created the network install source files from the OS will load just fine on a GUID partition table.
So I, too, am having this same problem, but I'm trying to figure out what's different between the source CD and how the network install tools for unattended deployment change it.
You are using an install CD that is Windows XP with Service Pack 2, correct?

R61 R&R won't start after "unmountable boot volume" error

Hello all,
New user, first post - after problem, of course.
I have an R61 Thinkpad with Windows XP on it. (SP2 or SP3, not sure). Has worked flawlessly for years, then the other day I got the dreaded "unmountable boot volume" error and it would not start.
No problem - I re-start, hit the ThinkVantage button, then hit F11 to use the R&R hidden on a separate partition of the hard drive........I get the black screen with the big progress bar, ok, then a blue screen......then nothing. Hangs up and sits there. I have repeated this about 5 times now.
No problem! - I was smart enough to make an R&R CD set a while ago! Put the primary R&R disk in the CD drive, start the machine, ThinkPad button, F12 this time to choose boot from CD.....much CD activity ensues and I once again get the black screen with the big progress bar. It takes much longer, and I get teh blue screen - BUT - then it goes one extra step to display the "ThinkVantage Rescue & Recovery 4" screen with the life preserver image.
Excellent, I thing - except it then hangs there. Just sits there. No disk activity. No keys will do anything.
I can find no threads here or on any other forum with this particular issue.
Am I fubar? Or is there something else I can do?
Thanks a bunch.
Solved!

Hi jim, welcome to the forums,
Is the hard drive recognised in BIOS, was there an entry in the boot list against HDD0?
Regardless of it being shown in BIOS / boot list or not, the first thing I would do is to reseat the hard drive and see if that helps, maybe over time it's lost contact to the mainboard socket. If you don't know how to do this you can find out at the R61 movies site.
The next thing I would do is run a hard drive diagnosis check from a bootable cd, these can be downloaded from all HDD manufacturer's websites e.g. Hitachi's Drive Fitness Test. It may be that the drive has simply gone bad after all those years of work.
Let us know how you get on

Help!!! T61 Blue Screen--unmountable boot volume-- error code 0000: Read verification failed

My computer is T61 (8891CT), but Blue Screen came out and reported--unmountable boot volume. I ran the diagnostic program and got the error code 0000: Read verification failed. I can’t run anything now including the restore and rescue. Has the hard drive died?
If the hard drive has died, I have to change the hard drive, but how to transfer the system (I don’t have any CD) and think vantage software? Thank you very much for you help.

Hi equalefk,
Yes, definitely sounds like it's time to replace the HDD.
Hope it helps.

Unmountable Boot Volume error message appears

Hi.
On monday I bought Norton Internet Security 2007 and tried to install it. I was reading a word document while I was installing it. I received an error message and was asked to restart Windows XP.
When I tried to restart Windows XP. I received a message telling me there was an error that caused Windows to shut down. The message ask me to choose between:
1.safe mode
2.safe mode with command prompt
3.last know good configuration
4.start windows normally.
I choose "start windows normally"
MS Windows XP started normally for a few seconds then instead of my normally log on page I received a blue screen with this message:
"A problem has been detected and windows has been shut down to prevent damage to your computer.
UNMOUNTABLE_BOOT_VOLUME
if this is the first time you have seen this error screen, restart your computer. If this screen appears again follow these steps.
If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching and shadowing. If you need to use safe mode to remove or disable components, restart your computer, press f8 to select start up options, and then select safe mode.
Technical information:
STOP: 0x00000ED (0x80E(1E30, 0xC000031, 0X000000000) "
And the then my computer shut down and then restart in the same sequence.
IT keep repeating the sequence: error message safe mode ect ect then blue screen, shut down and restart. Again and mo matter which mode I choose. I went on online(from a borrowed computer) to research what is going on with my notebook and I still have the problem. They told me I must uninstall the software that caused the problem. My question is have can I uninstall the software when I can't reach Window's log on and hence the control panel?
I'm at my wits end. Please help.

Hi
I dont know why but it seems that your master boot sector is damage
You could try to access the repair console (boot from original windows CD and then press R)
Then try to use this command: chkdsk /p
This command should repair some sectors on the HDD. Maybe it helps.
If not then you should format the whole HDD and reinstall the OS again!

Unmountable boot volume error blue screen

I have a toshibia laptop that has crashed, I am eventually getting the unmountable_boot_volume error blue screen, the recovery disks that i ordered will not work, just disk 1 loads windows file then goes to a black screen with the cursor pointer, computer repair does the same thing, os is windows 7 satellite c655d-s5120 64 bit the bios does show the hard drive name and the boot log is showing the last driver loaded is windows/system 32/drivers/atipcie.sys, can I order a recovery for the windows 7 or is there any other ideas to fix this?not sure why this is happening

If you've already ordered a set of recovery discs, you probably don't need to order another one. While it's possible that the discs are bad (and maybe you should call customer support just to see what they say), it's also possible that you have a hardware failure of some sort.

Unmountable Boot Volume, need help. trying to fix the problem via lan if posible?

any information i could recieve from Geek Squad would be appreciated. i have my computer purchased from best buy that i'm happy with, but my cousin's computer died with the unmountable boot volume error. i want to use my computer to fix his, or if possible fix his directly from the internet. any assisstance in this would be nice. thank you.

Hi AngeNeedsHelp!
I hope your cousin got the computer fixed. However,
this Unmountable Boot Volume error is not always fixed by simply reinstalling
the Operating System (OS). In fact, you may need to back up the drive using an
external USB Hard Drive Enclosure. Even
then the drive may not be readable if there are physical errors/damage, and
this is nearly impossible to do over the internet since they likely cannot boot
the computer? If there is important
information on the drive I would recommend taking it to a professional such as Geek
Squad® before attempting anything. Best
of luck!

Unmountable Boot Volume on XP and screen goes blank before repair begins

The XP Windows partition was seemingly working fine until I turned on the laptop this afternoon. Took a minute or so longer to boot than usual and I was prompted when it did load to update Acrobat, which I did and it rebooted. Took longer to boot, perhaps two or three minutes and I received an Unmountable Boot Volume error. I rebooted a few more times, same result. I tried system restore to three previous dates over past ten days and was told after attempted reloading that it had failed and I should try another day. Worried about my data, I went to safe mode to back up C: drive.
The general advice from MS is to use the Windows installation CD to repair the boot sector. With the CD in, Windows will boot and show my normal desktop and files, though will on perhaps the third item to load to memory, the screen goes blank and the loading seems to continue, as I hear sounds though not sure if it is the programs or the repair.
There does seem to be an ability for it to boot, just not maintain it through full load. Any suggestions short of reinstalling windows would be welcomed. Thank you.

I was unistalling some usless programs when my laptop died & when I turned it on I had unmountable boot volume 0x000000ED (the blue screen)
If I hit repair windows it goes to a black screen with the mouse (nothing else)
Now I tried f8 & then did command prompt but after it had gone to the loading files screen it had gone back to the blue screens with unmountable boot volume 0x000000E
I DL windows 7 repair but how do I get it to install when I cant get past the blue screen?
so i decide to repair it my self and then i found this great solution what helps me

Unmountable Boot Volume error in Z61T

Hi Members,
I just encountered the the Error Unmountable Boot volume error(Blue Screen) in my Z61T Think pad laptop.
I'm not sure what caused this error. Is it possible to fix the error?
I tried to go in to Recovery Console using XP CD and then repair the OS, but unfortunately when i go to repair mode i get another error which says unable to recognize the hard drive. Im really confused as of what is the exact problem with my laptop and also im worried about that data.
appreciate if anyone can throw some light in to the issue and help me out in fixing the same.
Thanks
Rajesh

If you believe that your hard disk/file system may be corrupted, try using any bootable diagnostic cd.They are operating system independent and will let you know if your HDD is getting corrupted.
Try the data life guard diagnostics(bootable).

HP DV7-7338ea Windows 8 Unmountable Boot Volume BSOD

The product concerned here is a HP DV7-7338ea with operating system Windows 8. I have been using it for just under 11 months and bought it with Windows 8 installed.
Problem descrpition:
I recently installed a new sound update for my laptop. I was promted to restart and once that happened, I recieved a BSOD with the error message: unmountable boot volume. When that happens, it restarts and goes into "preparing automatic repair" mood after which the screen goes black and the windows cursor shows and then that's it. I am left with no options or anything. I have tried pressing F11 on start up and then it says "please wait" and goes back to the same black screen. I have left it on for over an hour but it just remains there until my computr switches itself off for overheating (this has never happened before). I haven't recently installed any thing new apart from the HP update. Please help as I do not know what to do now. I have not backed up my files yet and they are too important for me to loose. Thanks
Update:
I ran a system check and it said the Hard Drive Short DST failed. Does this mean I have lost my files? The laptop had been operating very well until this latest HP update which may have corrupted my hard drive.
This question was solved.
View Solution.

A harddisk short DST fail means that either your harddrive is failing or have failed alltogether.
If you're still under warranty, contact your retailer or local HP store and get a replacement harddrive that you can switch yourself or have it sent in for service.
If you have an IT knowledgeable friend you might be able to salvage some of the data on the computer.
You can try removing the harddrive frmo your computer and connecting it to his.
Please let me know how it works.

HP Pavillion DV9700 - Vista 64bit - "Unmountable Boot Volume"

Hi there,
The problem I have with my DV9700 is it will no longer boot. It was working great, but the other night, I had to do a hard re-boot, and then it failed to start with a blue screen with "Unmountable Boot Volume". This is with the original Vista 64 bit Home Premium version. I chose the option "Self Recovery" but it just finishes up sitting there continually scanning for something?
The hard drive is the original factory installed setup. My question is, how do I get my machine back up and running please? I have a Windows Vista Backup that would run each week to an external 2TB USB drive, but I am guessing that this will not recreate an exact image of my computers state? I would also need to have Vista running to use the backup? Some years ago (2010), I created a complete backup to about 20 DVD's, but I am not sure how to use them as they are for recovery I think?
It looks like I need to buy a new hard drive but how do I go about using the backups I have to install to a new drive? Also, what is the largest hard drive I can use? Should I buy a SSD drive? I wanted at least a 1TB primary drive. Fry's Electronics has a Hybrid drive where the disk cache is solid state making it more affordable. I was thiking of getting one of these?
I would like to use my old original drive as a secondary drive if it is even possible to access its files. I have ordered a SATA caddy so I can mount it into the unused drive bay of the DV9700.
Anyway, I would truly appreciate any help please?
Thanks a million!!!

IdeaPad U430 unmountable Boot Volume

My Laptop is not working.
When I turn it on, after Lenovo logo I see a msg "Your PC ran in to a problem and need to restart...... search online for this error Unmountable Boot Volume."
Then automatically PC go to Auto Repair but after few seconds that msg dissapears.
I selected recovery option but after LEnovo logo nothing come on the screen.
I boot up with usb recovery media then also I can not see anything on the screen after logo.
What I can do
Thanks

Hi Nalinpr,
Welcome to Lenovo Community!
As per the query we understood that you are facing issue with unmountable boot volume in your Lenovo U430 laptop.
If your BIOS settings are configured to force the faster UDMA modes, this error may occur. In this situation, restart your computer and enter the BIOS and load the "fail-safe" default settings and reboot.
If neither of these issues are the cause for the Unmountable Boot Volume, then the issue most likely is caused by a damaged BOOT.INI file in the root directory of the boot drive or file system corruption.
Follow the steps below to correct these file system issues:
1) Start your computer with your windows 7 or any operating system which you have installed in the system CD-ROM,
2) When the Welcome to Setup screen appears, press R to Repair the installation using the Recovery Console
3) If you have a dual-boot or multiple-boot computer, select the Windows installation you want to access
4) Type the administrator password when you are prompted, if no administrator password is set then just press Enter
5) At the command prompt, type CHKDSK /R and then press Enter
6) Once CHKDSK has finished checking and repairing the hard drive, type EXIT and press Enter to restart your computer
If this procedure does not work, repeat it and use the fixboot command in step 5 instead of the chkdsk /r command. FIXBOOT writes a new partition boot sector to the system partition. The fixboot command is only available when you are using the Recovery Console.
As you also mentioned that the system hangs at Lenovo logo please try to remove the hard drive if possible and try to boot to BIOs and check, also try to run the LSC diagnostics.
Hope this helps. Do post back if issue persists!

Ashwin.S

Satellite Pro L10 - Unmountable Boot Volume

My Satellite Pro L10 loops at the boot process. After the Windows XP splash screen, the following error messages comes up: .... Unmountable boot volume... Technical Information: Stop: 0x000000ED...
I know this is nothing exceptional and doing a full recovery would solve the problem. But I don't want to loose the data (which of course is not backed up). I tried a Windows XP disc, but it won't boot from the cd/dvd drive pressing F12 or <0> and changing the boot order....
Can anyone help please?

Hi
Hmm the error message unmountable boot volume appears mostly if the HDD cannot be recognized during the booting. Why? Well, possibly the HDD malfunctions or the master boot record is faulty!
If you dont want to recover the notebook you could try to boot from the XP CD (press C button immediately after notebook powering) and to start the repair console.
In the repair console you could use the command chkdsk /p and after this you could fix the master boot record using the command fixboot or/and fixmbr.
If it does not help, the new OS installation is you last resort.
Ps: if you want to backup the data you can try to remove the HDD and try to connect it via external USB HDD controller to another computer.
