Problem to solve unmountable boot volume error with flash drive boot

Question: Problem to solve unmountable boot volume error with flash drive boot

Hello everyone

I have a Samsung laptop using Windows 10 and a couple of days ago a blue screen with an unmountable boot volume error showed up after booting, saying the computer would be restarted.After restart a loading recovery option message shows up with the samsung logo and then just a black screen appear and stays like that for hours.

After doing some research I downloaded the Media Creation Tool and uploaded it to my flash drive so I could boot using it and access the advanced option menu through the installation window. After that I plugged it in my laptop and tapped F2 until the BIOS menu appeared. I disabled Secure Boot and selected UEFI OS for OS boot selection, after restarting it again I now tapped F10 and a list with boot options showed, I selected my flash drive and in the first try a windows installation window appeared and I could open the advanced options menu and tried to use the command prompt to make a drive check up and restore as the instructions I found to solve this problem suggested,but the command prompt didn't start and there were just a frozen blue screen. I restarted the computer once again and this time I was going to follow the other way to solve it using the restore option in the advanced option menu.

Although, when I tried to access the menu again, it didn't work, I just got a black screen after the windows logo shows up for a few seconds and everytime I try it happens over and over again.

I'm trying to do the Media Creation Tool again but using the ISO option instead of uploading it directly to the flash drive, but I'm not sure if it's going to work.

Is there anything else I can do?

I can't create a restore drive because it needs a 32 GB flash drive and I don't have one right now.

Thanks in advance

I got an ASUS zenbook with windows 10 installed. When I turn it on it shows the BSOD error "unmountable boot volume". It keeps on re-starting forever and never display any "repair computer options".

To try and solve I created an Windows10 image on a usb device and tried to run the repair from that. This is not working since the laptop is freezing after I press "System Restore" or "Automatic repair". The only thing that works is the command prompt option. I ran the chkdsk /r command two times and it seems to run ok (checks all files) but are not able to provide an error log afterwards. When I restart the computer it goes back to the BSOD-message and is rebooting constantly.

Is there anything else I can try?

Answer:Unmountable boot volume - chkdsk /r does not solve issue

Hi Erdinger,

Do you see an option 'Startup repair' in the advanced options?
If you do, run it 3 times with a reboot between each.

Relevance 80.04% it goes.  I've been trying to install a new primary hard drive (WD 160GB IDE) and then install XP Pro.  However, each time it boots to the install disc I get the blue screen with the UNMOUNTABLE_BOOT_VOLUME error.  Most of the troubleshooting guides I've read in regards to this say to boot to the Recovery Console and run the check disc, however this is a brand new hard drive and I can't get to the Recovery console anyhow as it fails before that.  In addition, this is the second drive I've tried so I doubt it's the drive.  This is what I've done so far:BTW..I have a Dell Dimension 83001.  Per Dells suggestion, boot to XP with at least Service Pack 2.  I tried XP with SP3 and that didn't work.2.  Per Western Digitals suggestion, boot using the XP reinstall disc....that didn't work.3.  Swapped old 80 conductor 40 pin IDE cable for new.......that didn't work.4.  Tried setting jumper to master and cable select......neither worked.5.  Update BIOS to latest version...AO7...that didn't work.For what it's the bottom of the blue screen there is an error code as follows:STOP:0x000000ED (0x89E34030, 0xc000010, 0x00000000) this code after I booted to the reinstall discSTOP:0x000000ED (0x89E3B8C0, 0xc000010, 0x00000000) this code after I swapped the cableAny other ideas?

Hi, I'm helping a friend fix her computer. It is an HP running Windows XP Media Center Edition. The problem is it won't boot up at all. Not in safe mode, last known good configuration, etc. Most times when I try to start in safe mode it just restarts. When I tell it to start up in the Recovery Console it gives me a blue screen with the error message UNMOUNTABLE_BOOT_VOLUME and STOP: 0x000000ED (0x856CC9E0, 0xC0000006, 0x0000000, 0x0000000). I tried to boot using the recovery disc that came with the computer, and was able to get into the recovery console that way. I ran the diagnostic test and it gave me the error code HD521-2W. Does anyone have any suggestions?

Answer:Unmountable Boot Volume & Hard Drive Error HD521-2W

Often times, that error message can mean it's a physical error with the Hard Drive. You may want to try (if you're comfortable with the hardware) to make sure that the Hard Drive's physical connections are still intact. Can you get into recovery console? If so, your best bet is to run a "chkdsk /p /r" in recovery console and see if that works.

On my Acer Laptop (with NO disc drive) I was listening to a song on youtube while playing an online game in another tab. The laptop started to freak out on me and suddenly I heard a loud buzzing sound as the screen froze and the colors started to go crazy. I immediately tried to shut it down as I held the power button off, but it didn't seem to work, although I may have not pushed it down long enough. So I let go of the power button and pushed the battery off of the laptop. Of course it immediately shut off. When I put the battery back in, I went to start the laptop again, only it went to the screen giving me options to start in safe mode, last used start up mode, etc... None of the options have worked. It keeps trying to start up Windows XP, but then it goes straight to the blue screen of "Unmountable Boot Volume." So I'm wondering how to get windows xp from my pc onto a usb drive or something like that so I can fix my laptop. I can't seem to find a clear enough answer online. Please help! Thanks!

Answer:Help! Unmountable Boot Volume Error

Check your BIOS Setup, look to see if all your drives are recognized by BIOS.

If your hard drives are missing in BIOS, either the hard drive failed, the hard drive power or ribbon cable came loose, or you have a motherboard failure

Hi Everyone.......
New here and desperately need some help.............ty in advance for any suggestions!

My kids' desktop (HP w Windows XP) now has this blue screen come up with an error message about an unmountable boot volume. After looking through some threads, I think there are usually 2 hardware (we don't have any) or a virus. Being the kids computer with their websites, I'd surmise the virus part.

The problem is the only screens I can get on my computer now are the
1. Blue Error Screen
2. The screen with options of starting in various modes........none of which work......they all go back to the error screen
3. the awardbios setup utility screen

I have seen where ,if I can get to a prompt, I can run a check disk kind of thing.....but can't even get to a workable screen.
Other suggestion has been to put the windows xp cd in (which I can't find) and re-boot/re-start.

Thanks again for any help. I can't afford a new computer right now and just hope I don't have a $500 paperweight for a computer.


Answer:Unmountable Boot Volume Error

Just in case anyone else ever has this problem...I figured out how to fix it:

2. Restarted computer and followed the steps to re-install/repair

I am running a Windows XP media center edition SP3 on my old computer and since yesterday, my boot files became corrupted, giving me an "Unmountable Boot Volume" error. I plan on using the Windows XP recovery disk, but there's one problem: The computer never came with it. Any ideas on how to download it online onto a CD? Thanks.

Answer:Unmountable Boot Volume Error

You can download the Recovery Console here. Burn the iso with Imgburn or other burning software that can burn iso images. Boot the CD and then at the command line type:

chkdsk /r

This will probably take awhile. And, it may not fix the problem.

i could try and do a repair using the winxp cd, but id rather just try and get it working without that

Answer:Unmountable Boot Volume error

it's kind of a lame duck solution... but did you format the drive yourself when you installed it?

i had a similar problem with an external drive i had... i plugged it in and was using it out of the box for a while. it was causing problems, so i went to the disk manager utility and wiped it clean... let "my copy of windows" do the formatting... worked fine after that. for some reason the "initial factory formatting" was just whacked or something...

if you've already formatted it before using it, though... i don't know what to say. check maxtor's site and see if they have fancy utilities you can DL... or specific drivers, instead of the vanilla microsoft "USB mass storage unit" ones.

one other thing before i post this... are you using the "stop this device / safely remove hardware" thing before you unplug it (if you're unplugging it)? even though it's USB, it's a HD, and they get picky about having the rug pulled out of under them.

From what I've learned so far it's related to a hardware problem, but I'm trying to figure out which one of the hardware components is defective.

Can anyone confirm if that kind of error is really hardware related and if it is, how can I know which one of the hardware components is "broken".

I already tested my memory and it's working fine. But i need help on testing the other hardware.

If you guys need any more info just ask

Answer:Unmountable Boot Volume ERROR!

Hi, and welcome to TSG! Did your computer by chance get interrupted during a shut down cycle, or get shut down incorrectly (or abruptly)? That is one of the main causes of the unmountable boot volume.

It doesn't necessarily indicate an actual hardware problem. If you've been fiddling with the innards, it can indicate a problem with the cables or the actual hard drive.

If your computer was interrupted during shut down, then the boot.ini file is most likely corrupted. You'll need to do a repair to your operating system to fix that. Do you have the installation disk or a recovery disk that came with your system?

I managed to then select "don't restart on crash" which let me see what the error message is which basically comes up a big blue screen saying unmountable boot volume error.

Toshiba didn't give me a windows 7 or repair disk so im kind of really stuck.

You are between a rock and a hard place. You can (given that you have another computer) download a trial of win 7 (assuming you have a legit serial number) to do a repair install, but the download will be win 7 ultimate.

You are going to need an image of the version you have the serial number for.

Once you have the image boot from it into safe mode (F-8) and go to the device manager to display tab. Delete the video driver and re-start. win 7 should find a working video driver that will at least get you into a normla boot.

Good luck and let us know if you need help with that.

Then after loading some of the windows components it says "starting windows" in the bottom left corner where it was listing the components it was installing. After sitting there for a few moments I get a black screen for a sec then a blue screen of death with the UNMOUNTABLE BOOT VOLUME error.

Upon coming back from a week long trip yesterday, I turned on my computer only to find that it couldn't boot into Vista - after the green loading bars roll on for a bit the machine BSODs and shows up with the UNMOUNTABLE_BOOT_VOLUME, 0x000000ED error. I searched around a bit and found that the issue could perhaps be fixed by loading up the Vista Install disc and running the boot repair tools- however, I've run into a bit of trouble with it.
I can never fully load the disc, it seems. Upon seeing a gray bar or two load, what tends to happen is a black screen is loaded up and a white cursor is seen. Nothing happens afterwards, the install screen doesn't load up at all. Sometimes I get, in lieu of a black screen, the blue/turquoise wallpaper that shows up in the background of a Vista install, but none of the text or anything of the sort. Just a blank wallpaper with a cursor in front of it. I've let the machine sit in this state for at least a good two hours or so before I give up on it and try again, without any luck.
I seem to be a bit stuck as to what to do here, does anyone perhaps have a spot of advice? The data on my machine hasn't been backed up in a bit and reformatting/anything of the sort is out of the question until I back everything up, which is rather difficult given I can't even load up windows in the first place.
Any help would be appreciated a great deal, thanks very much!

So randomly this morning my computer decided to not startup. Every time I try to start it up I get a stop error: "Unmountable boot volume". So I google that on my laptop and look over several posted fixes on the issue. Except one problem: they all require my XP installation CD and my computer won't even boot up using that. Although its possible I didn't configure the BIOS properly to run it. When attempting to run the CD I just tap F12 for setup when my computer is starting up and selected boot device as the CD so its possible there is something I'm missing.

I have been looking through the topics posted here and I don't see anything that addresses all the issues I have, including lack of resources.

I have an HP Mini 210 netbook computer. About a week ago, it stopped. I was away for a few minutes and when I came back and there was some error message, with something about some input device. I didn't note the exact wording before I hit the power button which turned the computer right off. When I turned it back on, it would not boot Windows up. Every option offered by the you-have-had-a-badly-interrupted-windows-session-how-do-you-want-to-proceed list of options results in the same thing, a restart.

The start normally option proceeds for a few seconds before the blue screen comes up, and the system starts again.

The return to a previously good configuration does the same thing.

There are three safe mode startup options. Each scrolls through a list of drivers, I presume loading them, before stopping at Mup.sys. It sticks there for a few seconds then the blue screen comes up and the system starts again.

I was unable to read the blue screen because it flashes on and off too quickly, but my digital camera allowed me to get some idea of what at least one of the blue screens says. A problem was encountered and Windows was shut down to prevent damage. The problem was Umountable_Boot_Volume.

I've had my Toshiba Satellite L655D - 011 for less than 6 months. I've never really had problems with it that i couldn't fix until today.

So I restarted my computer because it was doing something funny with my msn. I always leave my msn appear offline, but for some reason it kept randomly making me appear online. But after that, it wouldn't start up anymore.

It kept sending me to this windows error recovery page. It tells me to either Repair my computer or to start windows normally. I tried both.

WHen i click repair my computer, it loads the necessary files, but after that it, just sends me to a black screen with only my cursor there.
If i choose to start it normally, it only goes up till the windows logo show before it sends me right back to windows recovery.

So what i did then, is open the Advanced boot options by pressing F8 at start up.

Running the computer in safemode just sends me back to the windows error recovery page.
Boot logging, last known good configuration and directory services restore mode also send me back to the windows error recovery page.

Then i went ahead and disabled automatic restart on system failure. It send me to this blue screen that said Unmountable Boot Volume. I didn't' really know what to do with that.

the Laptop doesn't have a floppy drive either
but I attempt to boot with USB pen drive since I have that option
installed BartPe and made a window xp bootup pen that didn't work

so I was wondering what other option do I have
could I plug the laptop in to my desktop computer and run the chkdsk or should disassemble the laptop HD and plug in a disclosure and USB it to my desktop computer and run the chkdsk??
or if you anybody have other suggestions would be most appreciated

Answer:Unmountable Boot Volume (CD DRIVE IS DEAD ALSO)

I have that BSOD Unmountable Boot VolumeClick to expand...

Check in the bios if it recognizes the hd.
Run some hd diagnostics (with vendor's utility).
You should be able to make a bootable pen drive in a similar way like a bootable CD.

In searching for a solution for my problem I?ve seen a lot of similar posts but nothing with my exact problem, so please excuse me for starting yet another thread on the subject.

I have two 160Gb hard drives installed (both the same make), one as primary master (C: with Windows XP Pro) with dvd writer as slave, the other as secondary master.

After a power cut I restarted my computer and got the following familiar screen:

We apologize for the inconvenience, but Windows did not start successfully. A recent hardware or software change might have caused this.

If your computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your file and folders, choose Last Known Good Configuration to revert to the most recent settings that worked.

If a previous start-up attempt was interrupted due to a power failure or because the power or reset button was pressed, or if you aren?t sure what caused the problem choose start windows normally.


When, I press any of the above, I then get the message (blue screen with white writing):

A problem has been detected and windows has been shut down to prevent damage to your computer.

I?m hoping someone can help me find a way to repair the hard drive for my wife?s <one-year-old HP Pavilion dm1 laptop so we can recover her data? at this point in time the partition on the drive is inaccessible (to me at least).

Here?s a brief rundown of the scenario. On Saturday morning my wife woke me up to tell me her laptop had blue-screened while she was working on an online document, and would no longer boot into Windows.

When the system is powered-up it seems to be going through a normal start-up process? displaying the Win7 pulsing logo for a minute or so. Then is switches to a notice asking if the user wants to run start-up repair (recommended) or start Windows normally. If start-up repair is selected the system will eventually display the default Win7 desktop wallpaper, and the hard drive light will indicate activity for a couple of minutes?. There?s even a mouse pointer that can be moved around? but no dialogs, controls, or anything else will ever appear. We left it in this state for more than 30 minutes to make sure.

If ?start Windows normally? is chosen the system will eventually blue-screen , with the error reported as ?Unmountable Boot Volume?.

I tried pulling the drive and dropping it into an external drive bay, but when I attempted to go into the main partition I received a notice that the drive needed to be formatted first (which I obviously didn?t do).

I?ve also tried booting into a Win7 installation disk via an external USB drive (the laptop d... Read more

Answer:BSOD Error - Unmountable Boot Volume

Alright, first and foremost, we want to backup the data. Then we can worry about recovering her computer. I would suggest downloading and burning to CD the program PartedMagic. Then follow the steps in my post to Backup Files Using Parted Magic.

After the files are backed up (assuming PartedMagic can read the drive, which it usually can, but if it cannot, you will have to do this next step to allow it to), use Advanced Boot Options to select Repair Your Computer and get to the System Recovery Options. Then select the command prompt. Do the following:chkdsk /r c:
chkdsk /r d:
chkdsk /r e:
chkdsk /r f:.etc until you get the message that the volume could not be opened for direct access. For any drives that do not give the message:
"Windows has checked the file system and found no problems"
run chkdsk again as above. In other words, if it says:
"Windows has made corrections to the file system"
after running the disk check, run the disk check again.

I realize you may only have one disk show up in Windows explorer, but you may have more than one disk through recovery options. This is because the system creates a hidden boot partition (which will be C: in recovery), you may have a recovery partition for your PC that is hidden (which will be D: in recovery), and you will have your primary Windows partition (which may be E: in recovery). A custom PC will likely have at least C: and D: to scan.

My daughter's Dell Latitude 620 laptop is showing the error message. I've read to enter the BIOS and then load the "fail-safe" default settings. I entered the BIOS pressing F2 upon boot-up. However, nowhere have I found the option to load the fail safe default. Where can I find this option?

Answer:Unmountable Boot Volume Error Message

On many Dells, the factory splits the hard drive into 2 partitions. One is where the OS is and all of your files, and the other is for restoring your computer to it's factory condition. Have you reformatted the drive? If so, you will most likely need to reinstall Windows, but try this first.1. At the BIOS, press F12.2. Select something like "Dell Recovery Boot" or something related.3. Follow the steps to do a recovery on your system.(Sorry about the lack of details, but I don't have much experience with this).Ask and Answer. The way of learning.

Its a Hard Drive Problem, you may be able to get to the files using a Ubuntu CD to boot from. You have to download Ubuntu and create a ISO image with the Downloaded file.

Hi I seem to be having a really bad problem at the moment...

Here is what happened: Yesterday I was playing a game and suddenly my PC decided to crash, I simply figured that it simply ran out of virtual memory. No, I got my favorite error "UNMOUNTABLE_BOOT_VOLUME". This isn't the first time I've encountered this error and I'm truly effin sick of it! I cannot afford to lose all of my files
After a few hours of screwing around I finally got my windows XP disk to work, so I ran the repair. I typed CHKDSK /R in the command prompt which repaired the drive then I did FIXBOOT to repair the section that was broken.
Afterwards, according to every help article I can find out there says 'Oh it'll boot fine' Yeah.. not the case, infact, it wouldn't boot up windows without the disk in the drive. Why is this happening? why doesn't it just fix it the way it should? Do I really have to reinstall windows and lose all my files because of this?

But it gets better!

For some odd reason when I started my computer up it would act as it was about to enter installation of XP but instead it would load windows off of the disk in my drive allowing me to go on as like nothing happened. Although, it seems to be that my computer decides when it wants to allow that, I got on twice, reset once, used system restore now I can't boot up, it goes right to setup. If I change the setup in the BIOS to load from the drive it won't load up it'll say "BOOT FAILED TO LOAD, INSERT WINDOWS DI... Read more

Answer:unmountable boot volume problem

If your laptop had an OEM OS install you may not be able to log back into the recovery console to restore the original registry hives. The system hive on OEM installations creates passwords and user accounts that did not exist previously. This is why RC didn't work.Now you have to do the following:1. Ship your drive out for recovery.  You will have to do this if your file security settings were Admin and power user only and/or if you encrypted the data.OR2, Use another PC. And this device likely the drive is a 2.5. It's a PATA if the cable interface is 40 pins (female which means 40 holes) wide and  SATA cables are only 7 pins wide.Now all you have to do is plug it in to another PC (set the jumpers to slave) and recover your data. You must log in as an Administrator on the PC or laptop so you may copy your data. Depending on your file security settings and if you encrypted the data, you may not be able to do it yourself.

Answer:unmountable boot volume problem

It's the hard drive, most likely. But, hard to tell if it's a bad drive or corrupted files, at this point. I can't tell from the Compaq website if error #1-02 is a physical failure or a MBR failure.You are right trying to run chkdsk /r. Double check your BIOS settings and that you have the correct CD (bootable) in the drive.Assuming that you can boot to the CD: If running chkdsk /r doesn't work, try fixmbr. Both commands would be run from the Windows Recovery Console located on the CD. If fixmbr doesn't work, try fixboot, also from the Recovery Console.If none of the above works, download and run the hard drive diagnostic utility from the drive manufacturer. You may need to remove the drive to determine the manufacturer - be sure to have the laptop turned off and remove the battery and AC adapter before removing the drive from the computer.Post back and let us know how you are doing.

Hello, the presario v2000 laptop running XP Home began having trouble. At first it started saying explorer.exe had to close, and would reboot but that quickly progressed to a blue screen error and would not load at all. I enabled boot logging at noticed it closed at the drivers...(nothing new was installed except apparently some windows updates).

Didnt work:
Safe Mode, Last Know Good..
Recovery Console-Chkdsk /r /p indicated there was an unrecoverable problem.
fixboot didnt work either. (now have NTLDR error)

Did testing on Memory, CPU, HDD. The only thing that raised flags was the Hard Drive accessibility which was very poor *(Hard drive throughput was good).

After doing fixboot, it now cant find NTLDR.

It seems to be like a hard drive failure. But I want to make sure. ANY SUGGESTIONS?

A) Is it clear that the Hard Drive is bad, and I should take it out, make it a slave to recover any data possible, and buy new HDD and reinstall?

B) attempt to re-partition (without data loss), enough to make room for a new xp install, and try to repair that way?


Thank You. Let me know if I'm missing something or there is a better procedure.

Every single time I boot the computer, the blue screen of death comes up with the same message "ummountable boot volume"

Now, I've tried everything suggested on microsoft, on this website and various other things. If I try to boot from the CD (windows xp cd) or Floppy (a boot disk), the computer doesn't even recognize it, it just won't go to MS DOS prompt, it just goes straight to the menu where it asks which mode you'd want to start windows (safe mode, normal mode, last known config...etc..etc...)

Tried starting on safe mode, it doesn't work either.

Tried to disable the options, "shadowing & caching", and restart in safe mode, doesn't work either.

If I could just get the computer to recognize the floppy drive and CD rom, at least I can re-install windows or do a chkdks /r ... and all the other things suggested.

Please can somebody help me!!!

I keep getting the blue screen error: Unmountable Boot volume 0x000000ED error when I start my Windows XP Pro computer. It happened a day ago when my computer crashed and I stupidly switched the mains power off. I have tried all the options: safe mode/ last known good configuration etc and it all ends up with the Unmountable boot volume error.

I have read previous posts about using the Win XP CD and running the recovery console and running chkdsk /p or chkdsk /r but I can't find my WIN XP CD. I have downloaded the boot diskettes from MS website and tried using them instead, and it does load the files, but when the 6th disk is in, instead of a welcome screen so that I can get into recovery console, another blue screen error appears with the error code 0x0000007B. I really don't know what to do now. Is that another error all together or is it related to the Unmountable boot Volume error?

Any ideas of what i can do next please? If there's really nothing that can be done to fix this, is there anyway I can still backup my files or is that too late? One thing I noticed is that when I type dir/w in DOS prompt, there are only 14 files on there, does that mean I have lost all my files or is it because of this error that I can't acces them?

Sorry about all the questions, any suggestions/help would be greatly appreciated.

Answer:Blue Screen ERROR! Unmountable Boot Volume

Hi folks. So I've scoured the internet looking for the solution to my problem. My computer shut down all of a sudden and now I'm getting the blue screen of death with the unmountable boot volume message.

I've read through about 50 pages of the same answer such as

etc.etc... they all say the same with the recovery console and the chkdsk

My problem is that I can't get to the recovery console screen after booting with the WinXP setup disk. it starts out with the "press f6 to install a 3rd party..." and then "press f2 to go to automated..." And then it finally goes to a screen where it says:

"The following list shows existing partitions and unpartitioned space on the computer." and gives me the options to setup Win XP in a partition, make a new partition, or delete a partition.

I don't want to delete anything and I can't setup windows in any of the partitions due to lack of space.

Any help or guidance you could give me would be greatly appreciated.

My Lenovo laptop will not boot. Every time I turn it on, it shows the Lenovo logo with the spinning circle of dots underneath it, but after about thirty seconds, it takes me to a BDOS screen with the error Unmountable Boot Volume. Every solution I've seen for this says to reinstall Windows 10 using a flash drive or dvd. I have a bootable flash drive with Windows 10 on it, however I cannot access the BIOS to tell my laptop to boot from USB instead. No matter what I do, I can't get to the BIOS screen. I've tried pushing every function key (with and without shift and/or the fn key). Any help on how to access BIOS? Or should I just buy a new laptop? I'm not sure what type of Lenovo laptop that I have (I think it's one of the flex systems). I only know that it doesn't have one of those novo buttons.

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: mode mode with command prompt

3.last know good configuration

Answer:Unmountable Boot Volume error message appears


I don?t 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!

I own a Compaq Presario M2000 notebook. Two days ago I was upset and banged the keyboard and tossed it onto my bed. Later on, I checked the screen and it was hang. So I restarted, but it always take me to a blue screen with a notice saying that Windows has detected a problem and shut down itself because Unmountable Boot Volume.

I've opened up to check the RAM, HDD, and Network Card, in case they were displaced accidentally. I also have tried to do the Recovery Process using the Windows XP CD. I've tried the chkdsk /r also the fixboot. None of them worked.

I also have tried all of these:

1. I tried to download the Seagate tool from Seagate's website, but it didn't work. Somehow, it always freeze.

2. I also have unplugged my network card, and starting the notebook, didn't work.

3. I took one of the two memory cards, and I try each of them in those two slots. Still nothing happen.

However, I also encountered an error message in DOS prompt:

"Intel UNDI, PXE-2.0 (build 082)

For Realtek RTL8139(X)/8130/810X PCI Fast Ethernet Controller v2.13 (forgot the numbers in the bracket)
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM"

From what I've read so far from the net, it might be cause by memory card and/or network card. But then again, I tossed it when it's still running, so I might scratch the hdd.

Anyone can guide me to fix this one? Many thanks in advanced

"Unmountable boot volume" usually means there is something VERY wrong with your hard drive. Back up everything important, if you haven't already. Your hard drive is probably dying on you.

I had a big problem with my samsung nc c10 running window xp. I had a unmountablebootvolume screen coming up when I rebooted after the netbook shot down unexpectedly.
I could not boot into the operating system and was showing first the black screen which ask you to choose which boot up you want to perform, then 2 seconds after it start booting into windows it has gone into the unmountablebootvolume screen. It got stuck into doing this over and over again every time I started the netbook. Not being able to get into windows, I could not check about any hardware or software problems.
What did worry me is that it got stuck in a loop. On the internet I have found a suggestion to use the operating system disk to repair the damage.
I have found a disk that came with the netbook called SYSTEM RECOVERY MEDIA and hoped I will be able to boot up from CD. Which it did. I had 3 partitions to choose from, one was for the some samsung software, C had 72 GB and D had 73GB. I have chosen C as it was where the operating system was in the first place, but it was more a guess work as I have never installed an operating system before. I probably made a mess of it all, but never mind. I thought it would only repair the broken parts but it had reinstalled the operating system again.
Now I am starting from scratch and I presume I have lost all the files I had on it, but does that mean that it has rewritten over the old installation or do I have 2 operating systems installed with one not working?

Answer:Reinstalled XP as unmountable boot volume problem.

You could have done a repair using a proper XP CD
the System restore media has reset it back to the day it came and may well have overwritten you data. You probably only have one operating system ... the new one.
all the drivers should be in as it has been set back to the day it came. but you will need to install all updates.

''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?

Maybe someone can help me out,

I am working on a Dell 2300 with Windows XP Pro that has a problem with Windows shutting completely down and a Kernel_Stack_Inpage_Error every once and a while. It alternates between the 0x00000077 and 0x0000007A message. In the parameters, the I/O Status Code always is a 0xC0000185 which is Status_IO_Device_Error which indicates improper termination, defective storage controller hardware, defective disk cabling, or two devices attempting to use the same system resources.

I have opened the computer up checked the cable between the hard drive and mother board and it looks fine. It fits snug and its not loose. I have looked at the IRQ's and the IDE controller is not sharing an IRQ with anything else. I have also run CHKDSK too.

After the Windows shuts down, this screen pops up, and it dumps the memory I shut the computer down. After I reboot the system, the Unmountable_Boot_Volume message comes up (0x000000ED). After restarting it over and over again alternating between Safe Mode and starting Windows normally it keeps on bringing the message up. Then after a while, the computer starts up normally. It will work fine after that.

This problem doesnt happen at a certain time or at certain intervals. It will just stop whatever it is doing and shut windows down. Sometimes it only lasts minutes, sometimes it will stay on for 12 hours.

Anybody think they know what the problem might be?

Answer:unmountable boot volume/kernel stack inpage error

have you tried either A) a new drive or B) a new cable?
a lot of these errors end up being hardware.

edit: just an additional thought.....that i/o address is really interesting. it's not memory. it seems as if to be your drive.
have you checked for boot sector viruses lately or viruses in general?

Answer:Unmountable Boot Volume/fan Erro/uncorrectable Data Error ...

Looks like a dead hard drive to me - the unmountable boot volume along with the IDE errors tend to support this. Means a new hard drive and a fresh install of Windows. I don't know about your data - you'd have to slave the drive to another system to see if anything is recoverable.

I'm unsure about the fan error - and would suspect that there's an overheating issue inside your case also. I'd recommend cleaning out the case with a can of compressed air - particularly the area with the loud fan. Don't use a vacuum cleaner or a garage air supply as it may damage your system.

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

Answer: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 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.

Answer: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.

Answer:[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 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.

Answer: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).

When i boot up it bsods and in safe mode too (tried all options in advanced settings either bsod's or hangs). \Windows\system32\drivers\CLASSPNP.SYS. is where the boot up fails. I tried to run from windowsrecovery disc but it becomes idle after trying to run recovery. I opened up the laptop and disconnected the bios battery (it was password protected, I don't remember ever password protecting it - possible virus?) then after an hour soldered it back. Put it back together checking all connections and dusting it off. The bios is now accessible. I ran memtest off a flash drive and uncovered no errors. I ran chkdsk from command prompt on the windows recovery disc. I've attached a pic of the results. I tried to get memory dump info for you. I set the debuginfotype to 1 for complete memory dump.
If i have left something out please let me know,

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

Hello, I recently got the 'blue screen of death' whilst trying to start my computer. I tried using the windows CD to fix the problem, but on my computer I get an error saying a .sys file is corrupted (Is that the file corrupted on my computer or on the CD?). But when I tried the same process on another computer it worked fine. When ever I try to enter safe mode on my computer I get the unmountable boot volume error.
Please help me on this, I have lots of school work on that computer and I need it by next wednesday!
I realy hope I dont have to completly reinstall windows cause nothing is backed up.

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!

Computer (HP Pavilion, Windows Vista 64bit) BSODs with error message Unmountable_boot_volume.

I have booted on F8 and attempted safe mode and all other options with same result.

I have booted on F1, selected CD drive as primary boot option, and attempted to boot from HP recovery disc. I get the following message: ATAPI IDE CD ROM Device version p2.00 Error: Unable to detect Atapi IDE Driver not loaded then goes to black screen CD-ROM=Q: Bad command or file name C:\>

I have also ran a memory diagnostic. I have pulled all 4 RAM chips and switched them around, unplugged the hard drive, unplugged the CPU fan, etc. Nothing works.

I think it may be dead.

Any ideas?

Answer:BSOD Unmountable Boot Volume but also will not boot from CD

 to the BC forum
The error code you are receiving is related to hard disk. Possible causes are the following.
- Faulty HDD cable 
- Severely corrupted file system on the hard disk 
- Failed hard disk (most common reason )
Please do the following steps one by one.
1 ) Replace the HDD SATA cable. If you don't have a spare one, borrow the cable connected to the optical drive.

2 ) Test the health condition of the HDD using manufacturer's diagnostic tool.
Identify the brand of your hard disk and download the appropriate DOS based diagnostic tool by referring the below link.
Let us know your findings after running the hard disk test. Also specify the exact model number of your system in next reply.

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.

When I put the harddrive in the good desktop tower, I couldn't find a slot, so I believe, ... Read more

This morning my Toshiba Satellite A40 gave me the following error:


And the tech info is:

*** STOP: 0x000000ED (0x857DFE30, 0xC0000015, 0x00000000, 0x00000000)

The microsoft support website tells me how to solve this using the windows xp installation CD - but all I have is the Toshiba recovery CD - and even that won't work - because it can't mount the drive to be able to format it!

I would greatly appreciate some help on how to sort this out.



Answer:Unmountable boot drive error on A40


if you can't get a XP CD from somewhere, you should go to a Toshiba service partner, if you don't want to reinstall the whole system.
