I just installed win 7 and now can't install fedira 13 on the partition that i made for it on the same drive. The problem is that after installation of win 7 i lost the ability to boot form cd. In bios i still have cd set up to boot first and drive second, but win 7 did something that overrides bios set up. I even tried Esc for boot menu, then i select to boot form cd, but it still boots in windows. What can I do to fix this?

Win7 does not have the power to tell what Bios should do. It works on what the Bios provides.

My guess is that you may have a defective CD which you should verify its MD5 or try booting with another machine.

I'll try that and let you know what happened; however, i suspect that it's not the cd because I have a proven ubuntu cd that i installed off of a few times, even just yesterday, but even that cd doesn't work and can't boot microsoft just overrides it and loads win 7. By the way i installed win 7 as an upgrade form vista, vista allowed me to boot form cd but after win 7 upgrade i lost that ability.
This really sucks.

I suggest you check the Bios again.

When you switch on a PC the first activity is the Bios taking the control. The Bios will boot whatever device the user has instructed in the Bios page.

Win7 can only get booted if it comes to the hard disk's turn to be booted. In my machines I arrange floppy, CD and then hard disk as the booting devices. Thus the Bios must check the floppy drive first. With nothing it proceeds to the CD/DVD drive. If there is nothing then the Bios boot the hard disks in the order I specified. I could put in about 10 internal disks, external disks, USB flash drives, eSata disks and Fire wire devices and select any one as my first boot disk. This is standard for any IBM compatible PC.

Thx it worked, you were right the cd was flawed.
