I'm not too sure why, but my 64bit Windows 7 dvd is having some isses booting... It is not the choose CD-ROM issue, I have already dealt with that and made the changes. When my system tells me to "press any key to boot from DVD/CD..." My keyboard just wont respond! I can never get it to actually want to boot from the disc... What is going on here??? --oh if it helps, I am using the newer thinner desktop keyboard, not the original one that came with the iMac. THANKS!
