Running windows 7 32 bit, Ultimate (upgraded from Windows 7 Professional). When I boot up my computer, it hangs at the windows logo, until eventually it BSODs if I allow it to boot normally. If I click on start up repair, it gives me the error below. I tried going and running in Safe Mode but it hangs on an AVG sys file, so I plugged in the drive to another machine as a USB drive and renamed all AVG files to see if that would solve the problem, but nothing. How can I try to resolve this? I thought about creating a recovery CD/DVD, but since I installed Windows & Profssional from a USB stick, then went to SP1, then upgraded to Ultimate, I am unsure how to create a recovery disk. And if I did, could I repair the Windows install without mesing up any current settings or program installations? ==================================================================== Windows failed to start. A Recent hardware or software change might be the cause. To fix the problem: 1. Insert your windows installation disc and restart your computer. 2. Choose your langugae settings, and then click next 3. Click "repair your computer." Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible.
