Umountable boot volume

haveu formmated your disk & installed an operating system ie Win7/Xp it seems u have not got an operating system.

After hitting the power button on your computer, throw it into "BOOT MODE" and select your hard drive. See if this helps your computer load. If so, you will have to go into your BIOS Setup and make your current hard drive your Primary Boot Device.


If this doesn't help, load your restore disc and check your drive for errors.

Your problem shouldn't be anything more than a few registry errors OR a boot problem.

> unmountable

The disk-drive cannot be "mounted", i.e., the motherboard cannot access it

> boot volume

To "boot" a computer is to load a small "loader" program from the disk-drive;
that program "pulls-up-by-the-boot-straps", to read the rest of Windows from the disk-drive.


If the disk-drive has "failed", then you'll get messages like the one that you reported.

Replace the disk-drive.

its called the blue screen of death and it could have been caused by something you installed recently or a hardware issue, have you tried booting your computer into safe-mode using the F8 key if you cannot boot into safe-mode without getting the same issue then you may have to format your hard drive

You need to boot your computer with recovery cd,if you do not have recovery cd,you can download one from the following link

perform 32 bit diags on hdd using drivers disc, if no error, boot your comp using windows disc and perform recovery console, perform chkdsk /p

hi,

When ur 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.
So, what do you do about it, panic and try to mount your boot in your computer...... No that is probably not a good idea.
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.

your harddisk got virus or some bed indexing units.
I also get this eerror then i have win xp bootable disk then i boot my cxomputer with win xp and go to recovery console then type "chkdsk /r"then press "y"
then it fix the eror on disk then i restart winxp and all worrking fine but my system has some virus theh i remove all virus from it with avast antivirus in boot time.

try not to delete partition 0 recovery disc, just delete partition 0 operating system

Sounds like a ram problem.
