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

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

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

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

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.)

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.

We have a Sony Vaio desktop computer with XP OS. My husband was working on the computer and the computer froze, he had to do a hard restart and that is what has started our problems.

When we turn on the computer, it loops through and keeps restarting. I can't get into safe mode or any of those on that page, it gets stuck at mup.sys and hangs. I have tried going into BIOS and changing the boot order to CD/DVD and I tried booting off of the recovery CD, where I only get a blue screen, I can't get anywhere. When I try to boot off the XP disk, it doesn't seem to recognize the disk and I never get an option to do chkdsk/r. The bluescreen that blinks with the error is a unmountable_boot_volume and the tech info. is STOP: 0X000000ED (0X81309E30, 0XC0000006, 0X00000000, 0X00000000).

I took the hard drive out and tried putting it into another tower and I get the same thing, so does this tell me that my hard drive is bad? We have videos of our kids on the harddrive, so I really want to do anything/everything possible to get it to work, before giving up and buying a new hard drive. I'm sorry, this is my first time posting, so I am not sure what else you would like to know. Thanks for any input or ideas I can do. I also read in my internet research that I could have a bad IDE cable on my harddrive, or I should get an 80-pin versus 40-pin, I am not sure which one I have.

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).

My system is 32B XP Pro, with 2 Seagate Barracuda 7200s running in RAID 1 (mirrored).  Windows is regularly updated.
I recently ran a routine Windows Security Essentials scan and it caught and removed Trojan Win32/Urausy.  The  Microsoft info site recommended running Windows Defender Offline for this one, so I tried running it from a USB flash drive, but the program hangs and won't run.  I had trouble burning an iso image to CD and gave up on Defender after some online research suggested that it no longer works with XP, for some reason.
So (sigh), I decided to try running Kaspersky Rescue Disk 10 from a flash drive. It loaded up just fine and appeared to recognize all my drives and partitions.  I ran it on the default setting first (which scans the boot sector and hidden startup objects).  It picked up Sinowal and cleaned it.
I ran it again--this time including most of the partitions on both drives in the scan. It picked up KillAV in an old Sunbelt Security Counterspy.msi file and cleaned it.  I haven't used Counterspy in a year or more.
Next, I shutdown the system and removed the flash drive.  When I started it back up, I got the Unmountable Boot Volume blue screen.  Rebooting gave the same result.
I tried to boot into safe mode and Recovery console and still got the blue screen.  Last known good configuration yielded the same.
I ran chkdsk /r from my XP install disc and it ... Read more

Okkk. So I've searched pretty much everywhere and I can't figure out what to do if my laptop doesn't recognize my hard drive. I put the Vista disk in and the only thing I'm able to use is the command prompt because none of the others work since it doesn't recognize hard disk. When i try to do chkdsk/r it says
''the type of the file system is NTFS.
cannot lock current drive.
Windows cannot run disk checking on this volume because it is write protected.''
Is there any way to get past this?
Or some way to get my computer to recognize the drivers?
thanks in advance.

I have the unmountable_boot_volume BSOD when I try to start up my computer. I have read many places that a way of possibly solving this error is by booting up my Vista install DVD and running the Startup Repair tool. However, I am unable to fully boot the DVD itself. It begins to load up (it loads through both a gray bar and a green cycling loading bar), but it never seems to get past a black screen with a white mouse cursor. Rarely does it even get to the main Vista Install screen, and the one or two times the machine made it there, after clicking the "Repair my computer" button, the computer hangs infinitely on a blank screen with a white mouse cursor, in front of the Vista install dvd wallpaper.

Is there a way to ensure the DVD gets to run the Startup Repair tool, or is there perhaps an alternate way of solving this boot volume error?

When I start the machine (XP Pro), it won’t boot in any mode. Going via F2 I can get to boot from CD but I don’t have an XP recovery CD for the machine as it was an OEM with pre-installed XP (Tried a friend’s 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 haven’t got any info re the machine apart from its a Toshiba U400.

I received a "unmountable boot volume" error on our laptop.
We have a Dell Vostro laptop with Windows XP

When I was trying to fix the boot error, I changed the BIOS Settings to load from CD first.
Then I loaded the Windows XP CD and attempted to run the Recovery, however, I received a message saying "Setup did not find any hard disk drives installed..."

What should I do next to try to fix this issue?
We hope the hard drive is not dead because we will have a lost quite a bit of information. I will appreciate any help you can provide. Thank you.

A:Did not find any hard disk drives while trying to fix unmountable boot volume error

The hard drive is the cause of the error. If you can't afford to lose the information, remove the hard drive and put it aside. Install a new drive and re-install the version of Windows you were using... Information on the bad drive might be recoverable by placing it into an external USB enclosure and accessing the files that way

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

So I went to boot up my PC this morning (Dell Dimension 9100) and received the BSOD with an error message reading "UNMOUNTABLE_BOOT_VOLUME". I tried to restarting a few times, booting in safe mode, booting with last known good settings; all resulted in the same failure.

Following several online resources, I next tried to run Windows Recovery Console off of my XP CD. It took a while for the console to load up and when it finally did, I ran "chkdsk /r" in the prompt. I received the following:
"CHKDSK is checking the volume...
CHKDSK is performing additonal checking or recovery.
0% completed."

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.

Any help is appreciate, thanks!

Hello,I have a Vaio VGN-FZ485U I purchased 4 years ago and it has received heavy use, notably playing movies/music and WoW. The hdd has been giving me issues recently but each time I was able to access Vaios recovery parition and repair the errors/perform a factory install; this time I cannot. I have Vista 32-bit with SP2 installed, and hadn't installed any new software or drivers recently.Booting normally either a) makes the laptop hang at the load screen before a BSOD about unmountable_boot_volume appears (with automatic restart disabled), or load to a black screen with a white cursor that is moveable. Booting using the safe mode variants and advanced options gives the same result. Attempting to load the Vaio recovery partition only gives the KSOD with the white cursor.I tried booting from the Vista Recovery CD as recommended to fix an unmountable_boot_volume error but I only get as far the KSOD with the white cursor. The CD was burned correctly as I tested it in another computer and it loads properly.Pressing shift or trying to access the task manager during the KSOD doesn't do anything.I checked the BIOS and the hdd is listed as IDE, though there is no option to switch between IDE and SATA anyway.I was able to boot from an Ubuntu LiveCD and access my hard drive following http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/, so wouldn't this mean the hdd is still working if I can still access it?I am ...

A:Vista BSOD Unmountable Boot Volume and KSOD with white cursor

Booting to the Ubuntu live CD does nothing to the hard drive. Sometimes you can still access your files and copy them somewhere else from a hard drive that is going out. It may be that the hard drive is able to be used as a slave, but not capable of booting an operating system.

A:blue screen at boot up "Unmountable-boot-volume"

This from TeckTips4U

"When booting up to Win XP you may get a error that reads "Unmountable Boot Volume". This is probably because your boot.ini file is messed up.

You can boot with your the XP CD and when you see the "Welcome to setup" screen press the letter R
You will get a dos-type prompt
Then type chkdsk /p (note the space before /p)and hit Enter
When that is done type fixboot and hit Enter
Y and Enter at the prompt
Then type exit and hit Enter
The system will now reboot into Windows

If for some reason that don't work for you, you can boot to the recovery console like above and...
Type chkdsk /r (note the space before /r) then enter
When done type "exit" and hit enter.
This will take longer, but the system should boot back into Windows."

A:unmountable boot volume

Depending how old your Dell computer is, your hard drive might be failing or has already failed. We had two Dells at my work that came up with "unmountable boot volume" error and both times the hard drive had failed. They were purchased in June 2003.

When your Dell begins to boot up, within the first few seconds you have an option to choose F12. By pressing this key it will allow you to choose bootup options. Once on that screen, choose the one that says Utility Partition. You can then run Dell's diagnostic on just the hard drive or the whole computer if you like, it does take longer though. It will tell you if there are any errors with the hard drive.

Good Luck, hope this helps you resolve the issue. Let the forum know if it does.

I am posting this under software, even though I was told it was a hardware issue, because I don't think I believe that.

Dell Dimension 2200 desktop running XP in my office at home. Everything was working fine until I tried to update some proprietary software from my company. (I think program relates to SQL Server somehow, if that helps?) There were three updates that I was supposed to do. System said first update completed successfully, but computer locked up to the point that I had to power it down manually. Second update, computer locks up again, this time update did NOT complete successfully. Manually powered down again, and tried second update a second time. This time completed successfully, but again the lockup.

Manually powered down again, then powered back on to do the third update. Machine will not boot. Keep getting BSOD stating "UNMOUNTABLE_BOOT_VOLUME". Have tried booting in Safe Mode, as well as "last known good configuration", with the same results. Double-checked that there were no disks in any of the drives.

I have tech support through my company, so I called. They said "hard drive issue, sorry, maybe time to buy a new computer".

Any less extreme ideas? It seems rather coincidental that a hardware failure would be immediately preceded by a software issue.

A:unmountable boot volume

This is probably caused by your boot.ini file being messed up. Boot from your Windows XP CD, select "R" for repair, and login to your Windows installation with your Administrative password. First run "checkdisk /p", and then "fixboot" and see if that fixes the problem. If not, boot into the disk again, run "checkdisk /r". If THAT does not work, boot one more time into the CD, and run "bootcfg /rebuild" and it will scan for your installation. Once it finds it, press Y, and then at the Load Identifier screen name it "Windows XP Home" or "Windows XP Professional" depending on your version. When it asks to enter load options, just press ENTER to skip it. Restart and you should be good to go.

Dell is going to have a new hard drive installed but in the meantime I would like to be able to copy some of the data. Most was already backed up to a portable hard drive but some items of convenience would be good to have. I have read of the solution on the MS site that requires the Windows XP CD. The problem is that Dell did not provide me with an XP CD when I purchased the computer.

My question is; Is there any way to get this thing started back up without that CD?

Here we go. It all started yesterday I started noticing that when I would search for something on bing and click on any of the search results that it would redirect me to some Bulls&^* page. So I immediately thought adware or spyware or something. I downloaded spybot search and destroy and ran it. It made me restart my computer and when I did I got a notice that windows automatic update was turned off. So I turned it back on and it downloaded new updates and when I started installing them there were FORTY new updates. Anyways I let them install and had to restart again and when I did... Boom.. BSOD Unmountable Boot Volume. I've ran chkdsk /r and fixboot and all that jazz to no avail. I really can't see my harddrive being dead from all this but anyways.. any ideas? I'm not positive on the size of the drive but I think it's 250G. It is a Dell Ispiron 530S running XP Professional. and I MIGHT have used 40 gigs worth of the drive. Any ideas would be much appreciated! sorry so long, just wanted to get it all out there. Also sorry if I posted this in the wrong forum... i'm new.

I got a new laptop 3 weeks ago, and now after a hard restart i got the Unmountable_boot_volume error.

When i power up it sits loading for 15 mins before i get the message something is wrong. It then proceeds to a new restart where it says starting automatic recovery, then the screen goes black (still powered on) and it stays like that until it gets a hard restart again. (I tried leving it like that for 8 hours)

It's a Lenovo U330, so there is the "novo" button. When i choose system recovery there, the same thing happens.

Is there a fix for this ? I do have another computer with win 8 i can create bootdisc from if that will work. I can always return it, but rma takes around 1 month and would be a waste of time if there is a easy fix for it.

I tried to use a bootdisk i made on a different computer, but the problem stays the same.
Made a rma on it, i can update when i get it back in a month if anyone's interested.

I'm trying to fix a friends laptop computer, it has blue screen of death Unmountable Boot Volume error, It will not work in safemode, normal mode or even last known good configuration. I have tried to to boot from the cd windows XP home and choose recovery console to try chkdsk but it says AUTOCHK.exe can not be found, please find it. I have tried fixboot and fixmbrBTW I can't get into Bios, he set a password for it and he does not remember the password, we tried all of the passwords he could think off. It is out of warranty.I wanted to do a repair install however the computer does not give me the option to do any repairs, on the partitions page it says,C: patition1 [unknown] 76309mb (76308 MB FREE) unpatitioned space 8mbIt gives me the option to delete or install.

A:Unmountable Boot Volume

The fact that...the partition file system is listed as "unknown" and that the data reflects an empty partition with no data on it...says to me that either the file system (NTFS) or the hard drive itself has a problem.Typically, the best thing to do is to employ data recovery software of your choice to move data files from the drive...before going any further.Unmountable boot volume errors are typically solved by running the chkdsk /r command...except when they are too serious to be solved by such. Yours appears to be beyond chkdsk /r.Unmountable Boot Volume - http://support.microsoft.com/kb/555302 LouisYou'll need to remove that hard drive from the laptop and attach it to another system...to do any file recovery and/or diagnostic.

Hi all,

I have a laptop (sony vaio) which crashed yday. I have been getting the message "unmountable boot volume" and I cannot even log into safe mode. Is there any way to fix this without losing data. The laptop doesnt come w an install CD since it is the OEM kinds and the online support person asked me to do a system restore (which would wipe away all data).

Then I went in and bought a rocketfish hard drive enclosure kit (2.5''). I removed the internal hard drive (IDE) and plugged it into the rockertfish and onto my desktop (compaq presario). I see a new drive (drive F but when I click it I cant seem to open anything at all ...even when I right click I see no functions at all. The hard drive enclosure kit comes with a USB cable w a dual head which serves for soem back up power. Any suggestions as to how to trouble shoot this.

Update: I used the paragon software which this website recommends. Looks like its working. It is transferring files to my external hard drive. Few more hours to go for the transfer. Hope I did not speak too soon!!!!

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

hi guys. I am using Acer Aspire 4740G and recently i cant boot my computer because of the blue screen error. Firstly when i started my laptop, it showed two options. One is to Launch startup repair and another to start windows normally. I had selected the first option but it would just give me a blank screen. I tried getting into safe mode but the computer just restarts. Okay so acer did provided me three recovery disc. I inserted the first one and it loaded. Until to a point when a browser appears and a message indicating "please wait a moment". Yeah right and that moment was two hours and the message remained. By the way that programmme is called acer e recovery management. I think my last option is to reformat my com. But i just cant access the erecovery to restore to factory settings. Any help or other way to reformat it?

So, my power goes out and I get the Unmountable Boot Volume error, I google it on the other computer in the house and find out how to fix it.

The problem is my computer doesn't have a floppy disk drive and I'm not sure where to get it, if I can at all, on a CD. (I'm talking about the boot drives or whatever they are called to go through the repair procedure to fix my computer).

I don't own any Windows XP Installation discs, my friend has one but it is for a Dell (not sure if it would work for my HP, I heard it would considering I wouldn't actually be installing Windows XP, or maybe it would I don't know)

I have an HP Windows XP Recovery Disk but that hasn't worked (freezes at a certain point, and it's a new unscratched disc so that isn't it) and there aren't any other options outside of the actual recovery.

I've also read that I need to install all my drivers for my HP and burn them to a CD because everything will be removed from the computer, which I can do on this computer but I'm not exactly sure how. (I don't even know if I actually have to do this?)

I've been researching this problem for over a month now, and have had people attempt to help me but nothing has worked. I'm just wondering if anyone on these forums could help me figure out my problem.

A:Unmountable Boot Volume

First thing, download and install the Diagnostic Utilities from the Hard Drive manufacturer, and burn them to disk.

Then boot your dead computer to this disk, and use the utilities to either verify the HD as being good or bad, or fix the drive if it's bad. This will also verify that your Optical drive is reading disks correctly.

The fact that your HP Recovery Disk freezes is very odd. Try that again after the procedure above. Each system is different, but it is likely that you will lose all your data if you do a reinstall using the HP disk.

Hi, I've had my laptop for just over two weeks. I've kept very good care of it, and have been tinkering around and making it look cool for the last couple days. Well, last night, I was just on MSN Messenger and on Facebook and my computer froze for a couple of minutes, so I turned it off. I'm not sure if there were updates going on or not. Would this potentially be the cause of my troubles?

So, when I went to restart it, the menu came out as expected. Gave me a few options of how to start Windows, I picked "Start Windows normally," as I always would. However, the screen with the glowing sign saying "Starting Windows" was going slower than usual. On average, it only takes around all of 10 seconds to get passed that part. Instead, it was sticking there for 45-50 seconds, and a BSoD came up. It only stays on there for not even a second. I've done this multiple times and am positive it says "UNMOUNTABLE_BOOT_VOLUME."

Safe mode gets me to "classpnp.sys" while loading and gives me the same blue screen. Startup repair also is not working. It will go to the bare, take little to no time, and just sit on a black screen with only your cursor on the screen. It stayed like that all night with no progression. I don't have any sort of installation disk or recovery disk, it did not come with it for some reason, which really frustrates me. If you can help me find the solution to my problem, I'd be ecstatic, and if you need any more detail that doesn't... Read more
