I managed to get into the device manager in safe mode and noticed that there were two generic ide hard drisk drive type 46 entrys and two generic ide hard disk drive type 47 entries. There were also two floppy disc drive entries. I tried to delete them but the comp would lock up before I got a chance to.
I dont want to have to format and re-install Windows as she has data that she doesnt want to lose. I did apply the bios update as you suggested though. I am currently xcloning drive c to the new D drive as I hope to try and boot from that instead. What do you think?
The other option I have is to delete the enum key and let windows re-install all of the hardware.
