Computer boots with blue screen - unmoutable boot volume message

Insert your XP CD and when you see ?Press any key to boot from CD? press a key. Now wait for the XP installer to finish loading up and you will be presented with the option to press R to Repair.

Press R.
The next screen will ask you which Windows? installation you would like to log on to. Normally the following will be listed:
1: C:\WINDOWS

Press 1, then Enter to continue.
You may now be asked for the Administrator password. If you know this type it and press Enter. If you don't know the Administrators password it may be blank. Just press Enter or type your username and password.

At the command prompt type these commands:
chkdsk c:/r

let it run through and it may take a long time to complete.

The other alternative is to remove the drive and put it in a USB enclosure or Slave it to another system to run chkdsk. You should have access to your Data.

Without any direct input from the PC's graphics card.

1920x1080 is simply the monitor's default resolution, but the monitor should be able to go all the way down to at least 1024x768 through the use of interpolation of the pixels.

You ought to be able to reduce the resolution using the monitor's own onscreen menu.

What do you mean by "[i]a long repetition of partion dialog[/i]"? If you are describing what seems like a continual list of lines of code this is perfectly normal and you should wait until it finishes the list. Then [u]Safe Mode[/u] will invoke.

[b]However, it is very odd that changing the screen resolution would result in an Unmountable Boot Volume error. How old is the HDD ?[/b]
