Question: tfght is missing how to fix without cd?
Answer: Insert my installation disk (Win 7 CD/DVD), boot from the disk, went to command prompt. Type following commands: bootrec /fixmbr bootrec /fixboot bootrec /rbuildbcd exit. Then click on 1st option (something like 'Fix startup') Then after a while asked for restart, pressed 'Finish' and then reboot.
