it sounds like your install is corrupt, you may need to make a fresh backup if you can.

this is from a genuine backup which has worked no problem before bunch of times never had a problem only when i wanted to upgrade my hdd from a wd 250gb blue to a wd 500gb black one

i fixed my problem also with my own system recovery restore windows 7 hp boot cd guess how i changed the settings in bios for my new wd 500gb hdd sata black one by in bios under advanced and went to the bottom to sata controller mode changed that to compatibility and put in my original recovery cds and worked windows booted with my new hdd . fing toshiba no help either going 2 charge me £30 for a disk that i already have.also a computer shop beside me was going to charge me £40 to fix it he didnt tell me the craic either
