Hello there I have a problem. I have an IBM thinkpad laptop and one day I did a microsoft update and everything was working fine.
The next day when i switched on the laptop, I got the dreaded BLUE screen with UNMOUNTABLE-BOOT_VOLUME and error code ***Stop: 0X000000ED (0x82F64900,0xc0000006, 0x00000000, 0x00000000)

I cannot find a way of loading the XP disc cuase i do not get the option. I tried F12 where it gave me the option to load a disc, but nothing happens.

Please HELP or Advise.
