No matter what I do I can't get Debian 6.0.6 or 6.0.7 to install. I tried installing it from the iso file and from the dvd. It keeps telling me it's not a bootable medium. I gave it 4 gigs of ram and a 34 gig virtual hard drive. I selected Debian 64 bit and it is the 64 bit iso file.

I installed Fedora 18 just fine from the iso file using the exact same settings.

What am I doing wrong?

This almost always means exactly what it says. Test the MD5 checksum of the media against what the site says it is supposed to be and see if they match.
Also if you need further assistance you need to post the hosts information and the guests log file (as an attachment)

I got it. I had to use the live install.
