I had the SAME EXACT problem with a friends laptop which is what brought me here looking for a solution. Unfortunatly none of the answers provided here were working but I figured it out and thought Id reg and try to answer this once and for all.
To boot from CD:
When you power on, enter the password (if you have one) then press "C"
weird right?
For whatever reason thats how its done.
Im reinstalling windows now. Finally.
Still cant enter the bios but at least I can get windows working again (had a bad ntfs.sys file) and once I do I guess I can use the windows application to access it.
