I was running the Windows 7 home premium 32bit upgrade on a Toshiba laptop that was running Vista Home Premium 32bit. The upgrade process rebooted at somepoint and now it keeps rebooting to a DOS window witha command prompt on drive X. If I try to run the install.exe off drive D (CD-ROM) it starts the process and then stops saying the installation booted of the Windows 7 installation CD please remove the CD and restart. I cannot get past this endless loop. Nothing will boot completely.
