I have been fighting getting Windows 7 RC 1 to install for 2 days now. Tried 3 different burned copies of Windows 7 RC 1 in a couple of formats due to a CD/DVD Driver issue. So, I decided to totally delete any partitions on the computer that I am installing it on. That's right, no partitions at all! Strangely enough, it's installing as we speak. Weird huh? Right now it's sitting at 96% and continuing on its way. Weird that when I tried to install before it created partitions then gave me an error for the install about CD/DVD drivers missing, or that I needed to insert the media into the drive to install it when in fact that the media was in the drive already. Now I am just waiting for a reboot, I think. But, it's definitely done expanding the files. Alas, it stopped responding. So here goes a reboot to see what happens. That worked... Setup is now updating the registry. **Apologize for the commentary like a sports broadcaster, but I just thought I should share this interesting development as I'm installing Windows 7 without creating any partitions!** Ah... The final steps before putting in the CD Key! Just about there though! **NOTE: To get it to install even with the CD/DVD Driver issue was that I just deleted the partitions, selected the unformatted partition for it to install on... AND... VOILA! It's just about done. I'll let you know how it goes from here in a reply to this thread.
