Home Hardware UNMOUNTABLE_BOOT_VOLUME Stop 0x000000ED



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


If this is the first time you’ve seen this stop error screen, restart your computer.  If this screen appears again, follow these steps:

Check to make sure any new 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 problems continue, disable or remove any newly installed hardware or software.  Disable BIOS memory options such as caching or shadowing.  If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup options, and then select Safe Mode.

This workstation kept rebooting when it was trying to start windows.  Blue screen errors usually indicate a problem with RAM, but this particular error was solved by running CHKDSK /r and then FIXBOOT.

Simply boot to your Windows XP disk and select Restore.  When you get the prompt, type CHKDSK /r and let that bad boy run (mine took over an hour).  Then run FIXBOOT afterwards and you might be good to go.

Good luck!
