Sorry in advance for bringing up this subject again. I read through all my searches for this problem and haven't any luck. Got the bootmgr is compresssed error when starting up because of doing the compressing option. I do not have any dics to use to boot up from. I've downloaded the Windows 7 system recovery disc and made it into a bootable disc. But when i try booting up and hit F8, it doesn't work. How do i get into my bios to choose the option to boot from cd instead of hard drive. Any advise would be much appreciated.
