I installed Debian (6.07) on a PC. I wanted to install Ubuntu (12.10) after, but I could not boot to CD after Debian was installed. In fact no bootable disk(CD or floppy) would load once Debian was installed.

I can boot to all of these media if I unplug the HDD.

What's going on here?

Sounds like you have to change the boot order in BIOS –  Simon Apr 5 '13 at 17:16
    
Boot order is Floppy/cd/hdd Even if I disable the hdd boot order, it still hands and never loads the bootable media. If I physically unplugged the hdd data cable (ide) it boots into the media just fine. If I plug the hdd back in, even having it not bootable, the boot hangs after the bios post. –  Android Addict Apr 5 '13 at 17:20

My guess is a faulty/corrupted hard drive. Try removing the drive, booting into a live cd, then reconnecting the drive. Then use fsck to check the hard drive. If that does not work, you could try making a new partition table using fdisk or similar tools.

It could also be your BIOS configuration. Check that and make sure your removable media/cd drive is before your hard drive.

EDIT: Ignore that last paragraph as I just saw the comments to the question.

How do I load a disk utility if I cannot get it to boot into another os other than debian? –  Android Addict Apr 5 '13 at 17:21
    
It seems my only recourse is to wipe the drive and start over. –  Android Addict Apr 5 '13 at 17:22
    
As I stated remove the hard drive then boot into cd then reconnect the drive –  wolfo9999 Apr 5 '13 at 17:22
    
That's what I am doing now - wiping and starting over with Ubuntu. I just really want to know why the debian install prevented me from booting into another os? –  Android Addict Apr 5 '13 at 17:23
    
Maybe the install corrupted your hard drive, coupled with a possibly buggy bios, caused external boot methods to be disabled. –  wolfo9999 Apr 5 '13 at 17:25
