OK my favorite geek has moved far away from me so now I am left to fend for myself.
I have recieved a stop error on my home PC.
I have an (old i know) dimensions 4700 and moved it from one room to another about 2 weeks ago. It was behaving akward as of late. Well a few days ago I got the blue screen of death with the stop error code. and and UNMOUNTABLE_BOOT_VOLUME code
I have tried to get it to boot from windows cd and it jsut cycles back to the blue screen.
I tried safe mode, all options, I changed the bio-setting to boot from cd and still nothing. OK so I thought maybe hard drive went bad, then my supergeek says it might be my mother board.
Any suggestions???
Oh yeah and getting a new PC is out of pocket book range at this moment...
HELP!!!

welcome to PCHF Geeklover,

1. Boot from your Windows XP CD. You might need to change the settings at the laptop's BIOS. Most modern BIOS nowadays support a "boot menu", where you can specify which device to boot from without changing the CMOS settings. It is usually tied to the F9 or F10 keypress before the machine boots.

2. I do not know if you have done a fresh Windows XP installation before, but if you haven't, what happens now is that the Windows XP installer will load the various drivers and system files in order for the installer to fully run. Initially it will ask you to press F6 if you need to install 3rd party hard disk drivers and F2 to run automated recovery. Ignore those and wait till you reach this screen:

3. Notice the second option: "To repair a Windows XP installation using Recovery Console, press R." Do what it says; press R.
4. You will be asked to press Enter if you want to use a custom keyboard layout. Either wait for the 5 seconds to expire, or press Esc to get this following screen:

5. Normally you should only see one installation as in the screenshot, which is usually at C:\WINDOWS. Press 1 as in the screenshot to select that installation.
6. There is an Administrator account built-in in Windows XP and is usually transparent to the end user unless he/she activates it and uses it. By default there is no password for the Administrator; just press Enter. If you are unable to log in without a password, you should ask who has set the password before, or call your laptop service personnel.
7. Now, type the following command, fixboot, as in the screenshot. This will fix your corrupted boot sector on your hard disk.

8. Type exit and your laptop will reboot. Remove the installation disk and your system should boot as normal.
9. If your system still does not boot, you might want to try fixmbr instead of fixboot at item 7. If you have multiple operating systems installed in your hard disk, you will need to reconfigure them to appear as a choice in the boot menu again. You should only do this if fixboot really doesn't work.

10. If these steps still do not work for you, or if the problem returns time and again, you might have a failing hard disk, or you have a virus in your computer that is corrupting your boot sector. Either scenario would justify sending your laptop for service, especially if you'd like to avoid all the possible headaches and possible voiding of warranty associated with fixing it manually.

Its a desktop PC, and I tried all sources to get it to boot. It just wont boot at all from anything I changed the bios to boot from disc, even tried to get it to boot from thumb drive...nothing.

do you have a windows install disc so you can run a repair.

yeah have disc. It just wont run it

One more thing:
Tech info
STOP: 0x000000ED (0x82386420, 0xC000009C, 0x00000000, 0x00000000)
so is it time to get a new hard drive? mothre board? or (gulp) desktop???
