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?

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.

A:Unmountable Boot Volume can't boot from disk

Read other 8 answers

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).

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.

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

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?

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

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

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.

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?

If the computer is a Dell model, try tapping the F8 function key during boot up. This may call up Dell's "Advanced Recovery Options" utility. That should give you the option to restore the computer to like new conditions, wiping out all of your documents and other files as well as any software installed to the computer after it left the factory.

I'm running a dual boot system (currently running Linux Ubuntu 8.04/Windows XP Pro SP2) here, and I've created myself a little problem. :x

I went to uninstall Ubuntu, and deleted the partition for it first (It was late, I have no idea what I was thinking) which of course resulted in a GRUB loader fail. After much hassle, I reinstalled Ubuntu 7.10 and reupgraded to 8.04, and that's the only system I can run right now. My Windows 2000/NT/XP loader on the OS select screen boots fine until I get to the loader. It gives me the screen for a split second, then gives me a blue screen saying "UNMOUNTABLE_BOOT_VOLUME". I've tried messing with the partition tables using Testdisk from CGsecurity. I can't seem to figure it out though.

"Unmountable Boot Volume". This is probably because your boot.ini file is messed up.

You can boot to the XP cd and when you see the Welcome to setup press the letter R
You will get a dos prompt
Then type "chkdsk /p" without the quotes 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" then enter
When done type "exit" and hit enter.
This will take longer, but the system should boot back into Windows.

I have done the above on a number of machines, and it always works.

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.

When I turn on my PC, the message "Unmountable Boot Volume" flashes on the screen before it attempts a repair that never finishes. I do not have bootable back up media.  I do have most of my data backed up. If I replace the hard drive, how do I get windows loaded on it?   Can I get windows 10?   There are two hard drive slots.  Can I get two hard drive that I could either mirror or have one as a bootable backup>

Richard_P_White Hello;Allow me to welcome you to the HP forums! These problems are generally due to one of two basic problems:1) Failed hard drive2) Corrupted/missing boot loader filesAs to the first, please follow the directions in this link for testing your hard drive: http://support.hp.com/us-en/document/c00439024If that confirms your drive has failed, then you need to replace it.  Please report back if that is the case.As to the second, you will need access to a working PC for this step in order to create the media needed to repair your PC boot loader.Once you have that, please download and create Win10 install media from this link: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10Yes ... I know that is for Win10, but it uses the same generation boot loader as Win8x, so it can be used to do boot loader repairs for Win8x as well as for Win10.Boot from the media you created, and follow the directions in this link:  http://www.windowswally.com/how-to-fix-error-code-0xc0000185/You will probably have to run Startup Repair three times for it to fix all the boot loader problems.When done, your PC should boot OK. If it does not, and your hard drive has NOT failed, then to restore your PC, you would need to order HP Recovery Media.  This is a set of DVDs and a CD, or USB stick, that will erase the hard drive (removing all data, settings, and applications, reinstall the original OS, drivers, and some HP Utiliti...

Can someone please tell me if I can use a Windows XP Professional disk to repair a Windows XP Home Edition unmountable boot volume? My sister-in-law's Dell Dimension 8400 is getting that error when she starts the PC. She can't locate the disks that came with the PC and I only have an XP Pro disk.
I repaired my laptop using recovery console about a year ago but that is XP Pro also.

Thanks for any help and advice anyone can offer.

Hey guys, I got the blue screen of death today saying Unmountable Boot Volume.

I'm using a Dell Inspiron 6000.
Windows XP Pro

I found out that if you use the XP Setup cd you can run a recovery. I tried 3 cds but they failed to boot.
So, I also disabled the boot from hard disk. Tried it again, then got an error message saying :"No bootable devices, strike F1 to retry reboot."

Can I fix this or do I need to reformat?

Please help.

Recovery Console from a Windows Startup CDNote: You may need to change the boot order in the BIOS so that the CD-ROM is the first device in the boot order to be able to boot from the Windows installation disk.To run the Recovery Console from the Windows XP startup disks or the Windows XP CD-ROM, follow these steps:1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted.2. When the "Welcome to Setup" screen appears, press R to start the Recovery Console.3.

Hi there,

A few days back, I attempted to boot up my computer, and rather than seeing the usual Vista welcome screen, I had a choice of starting Windows normally or running a repair. I turned off automatic restart upon error, as I suspected the BSOD. I ran windows normally, and as I thought I got the BSOD, with the error...


This is also accompanied by a ticking sound coming from my hard drive (Which I know is not good)

The first thing I did was to try to run the computer in all versions of safe mode, and this does not work. I then tried to run the computer with the last known good configuration, and again this does not work.

I headed to Google, and read about using the "chkdsk /r" command in the command prompt having booted with a CD (This advice was for a Windows XP operating system). I don't have the original Vista discs, so I downloaded a recovery disk .ISO and burned it to a DVD. I managed to boot from this disc, and get to the recovery console.

My first problem was that the computer couldn't find my operating system, and prompted me to "Load Drivers". I ignored this, and then got onto the screen that shows the various recovery options, such as boot repair. I attempted boot repair, and this did nothing. I then used the "chkdsk /r c:" command. The process took a while, and it found some errors in the first stage. It identified some sections that "could not be read"

The chkdsk process contin... Read more

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 decided to remove some dust from my desktop by removing the heatsink or CPU fan. Well, after I installed it back and restarted my windows XP, my computer can pass the splash XP screen and just when it hits windows, my computer auto restarts and a blue screen appears saying that NTFS.sys (If i remembered correctly) is causing a problem to my computer, and to prevent further damage, my computer has auto shut itself down.

When i try to restart my comp, it won't get pass the windows xp splash screen, it just jumps into the blue error screen again.

This is what the error screen says:



If this is the first time this has happened to you, restart your computer. If this screen appears again, follow these steps:

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

If problem continues, disable or remove any newly installed hardware or software.

Disable BIOS memory options such as caching or shadowing.

You can actually consider yourself lucky, STOP error 0x00 aka UNMOUNTABLE_BOOT_VOLUME is the easiest BSoD to fix.

Resart your machine get into the BIOS, make your CD-ROM your first boot device, restart, boot from the XP installer disk, Press "R"- this will take you to the recovery console.

in the recovery console type

chkdsk /p

when this finishes type


it will say that this is very dangerous blah, blah.. say Yes.

reboot without the XP CD, this time windows should load.

If it doesnt work, perform thje same operations but this time just use
chkdsk /r
you probably wont need to do a fixboot this time- but chkdsk /r takes more time.

Have seen a few suggestions for this problem.

One says to ensure latest win updates are on - I did that.

One that worked involved doing a CHKDSK and/or FIXBOOT.

BUT - after 1 or 2 restarts, the problem recurs.

Latest Virus scan was clean.

Possible causes? Thanks

You might try a system repair. It appears that the boot files are getting corrupted, hard to say why that's happening. It could also be hardware or an application corrupting them.

My Dell 4700 has produced the blue screen stop error "unmountable boot volume". I cannot get it to restart at all. 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?

Hi,.. I've got an unmountable boot volume message on boot up of my C:/ which is a 500GB WD Raptor. I've tried to get it to boot up all day. Last known good config, Safe Mode, System Repar Disk and the Win7 Disk. No luck so I just pulled it out and put it in an external, connected to my ASUS Laptop. I can see the WD Raptor 500GB. It's denying me access to the information but it's partitioned it, and called it System Reserve which include three folders: Boot, System Volume Information and Temp. I'm just running a Check Disk on it now.

Question: What happened??.. and is it stuffed???
