I am doing an upgrade from XP to Windows 7. I have done this numerous times with no problems until today. I put in the disc for the upgrade and loaded the Boot Device Menu (F12). Then I selected Onboard or USB CD-ROM Drive and I can hear the CD spinning but it does nothing. It wont load and the 'Onboard or USB CD-ROM Drive' option stays highlighted. I just installed XP doing this exact same method because I installed a new harddrive and I had no problems. It only occurred once I put in the W7 disc. any ideas?Thanks!
