blue screen - 0x000000ED (UNMOUNTABLE_BOOT_VOLUME)

Hello, I have Windows Vista Ultimate-32bit.

i have a dell xps m1530 laptop
while searching on there website, i found the solution for it, but cannot understand it..



0xED & 0x7B

Stop 0x000000ED (UNMOUNTABLE_BOOT_VOLUME)

I was getting one of the blue screen error messages everytime... When I put the cd in, everythings fine until I come across the "LOAD DRIVERS" screen. I believe there's supposed to be a driver showing saying "windows vista" or something but nothing appears... the screen's just blank with two buttons saying "Load Driver"

which driver shud we load manually....


and "Next." I tried clicking on "Load Drivers" but I don't know which drivers to load or what to click.

and when clicking NEXT ...
startup repair
system restore
windows complete pc restore
windows memory diagnostic tool
cmd

none of the above works.

only recovery disk is available and i cannot see my OS hard disk...



Can anyone please help me?
