Help UnMountable_Boot_Volume

May 24, 2009 at 21:27:49
Specs: Windows XP
When I would try to run my computer it goes on this blue screen. I belive its becuase the boot.ini is corrupted or deleted and i tried everything that the foroums say how to fix them are but it won't work. For instance, it would say "To the Which Windows installation would you like to log onto question, press 1 and then Enter."

But mine wouldn't never say that. I would try to run CHKDSK /P but it would get to like 50% and it doesn't seem to go any farther. So if anyone could help me at all please post a reply it would be highly appreciated. Thanks in advance

Boot off the XP CD, press R for the recovery console, type in CHKDSK /R & press ENTER. Then wait...it may take as long as an hour. When it finishes, type EXIT & press ENTER.

You wrote /P in the original post.

If you can't reinstall Windows using the "repair install" method, try testing your RAM with memtest86.

I did /P when I first posted but after I saw your post I tried /R but it still froze on 50%.
Isn't there a better way I could fix my computer instead of re-installing windows?

Find a list of STOP MESSAGES(BSOD) here:
http://aumha.org/win5/kbestop.htm
Click "21a" at the right side of that page.

Unlikely you would understand that.

You might try to get into Windows Safe-Mode to
Try System Restore to a date when all was good.
Start >All Programs >Accessories >System Tools

Using System Restore too many times can cause
more harm than good. After doing a restore
that does not fix a problem, then UNDO the
Restoration, and try another restore point, or
just do the UNDO.

I tried to get in with Safe mode but it didn't work so is there any other way for me to fix the computer through the recovery CD?

sight for how to use it.

"IT" Is fixing the fatal system error and the ways you described how to fix "it" was to get into the windows and do a system restore but I can't get into windows I get the screen right before the login screen..

And the "it still didn't work" is when you go in the cd and press continue, then agree with terms F8 and then you can press contuine or repair and hit te repair but it stopped and said it couldn't fix it or something like that.

You said --- ...with the terms and condition by pressing F8 and it still didn't work.

I am trying to repair the computer. I read in a foroum that if you wait until the second time the disk sais repair it'll repair your computer with almost no data loss unlike if you re-install windows you lose it all and this is what I was trying.

But when I would run the second repair, the repair would stop and say there is a problem so that option is worthless. Isn't there a way to fix it using the CD with like Fixboot or CHKDSK or the other commands on that system.

And if it helps at all I have a Dell Microsoft Windows XP.

Dell computers usually have a recovery partition. If this has been removed, or is otherwise inaccessible, try the following.

Remove the hard drive and slave it to another computer. Backup (copy) all important data (you may need to take ownership of the files/folders). Put the drive back into the original machine and format, then install Windows.

Judging by your responses above, this is the only option left to you (other than taking it to a shop).

Please let us know if you found someone's advice to be helpful.

I already tried to re-install windows but it froze on a screen so I once again had to manually restart.

I think my hard drive is completly fried now though since I ran a dell diagostics test and got a Read test error - 0f00:0244 and a Verify Test - 0f00:1a44

Thanks for posts.
