I recently upgraded my proc, mobo, and added memory. I reinstalled WinXP and subsequently attempted upgrading to Win7. For some reason my boot sector now gives me 2 choices, 1. former operating system 2. Windows Rollback. I upgraded my Laptop and this did not happen. Upon booting the Desktop System, i checked all BIOS settings and believe all is good in that department. I only have a very few seconds to choose which OS i want to boot into...when i let the Win7 boot, i get the logo then a theme screen and the boot goes no further. I have a feeling that I may have screwed up when i installed Win7 in that i removed the disk after the PC rebooted. How do i recover? And I don't need a dual boot system either. Win7 is running great on my laptop and netbook. In my opinion Win7 is one of smarter things that MS has done. Any guidance is greatly appreciated. Cheers and Beers to all.
