Can't install Win7 when booting from Disk
I have a little problem I was wondering if someone has some suggestions to fix.
I have a D/R Win7 upgrade disk to install Win7. Have successfully installed Win7 from within XP, but wanted to reformat harddrive before install. So, I tried to boot from disk. I'm able to boot from disk, get long white bar at bottom of screen, but after that just get flowery screen and nothing else happens. My computer is a Dell 8300. I tried disk in my laptop, Dell, and was able to boot-install Win7 on that, so disk is okay.
Any help would be greatly appreciated for my computer knowledge is beginner/novice.
