Okay i have been using Windows 7 for approximately 10 months and it never gave me any trouble...i have using it all along as the beta versions rolled in to the final 7600 build. None gave me problems. But just a few days ago i rebooted my computer and then my windows 7 got stuck at a black screen just before the desktop appears. The mouse pointer was the only thing visible, sometimes movable and sometimes not. I installed XP on a different partition and then i tried installing Windows 7 and to my surprise when it restarts when "expanding files" and then when the setup should continue, it hangs at "setup is starting" screen with the little blue circle rotating indefinitely. This has NEVER happened before, not with upgrade or with clean install on the very same PC. I tried installing it using a flash drive..using a dvd.... but nothing helped. I tried removing external devices but no avail. ON XP i ran this command (G:\boot\bootsect.exe /nt52 ALL /force) to get rid of the nasty bootloader screen when i finally accepted that my previous installation of windows 7 cant be repaired. After getting rid of the bootloader screen, i manually deleted my Windows 7 files from XP. The point of interest here is that when i again tried installing Windows 7, when it restarted to continue the setup, i got the bootloader screen again (which is obvious) BUT, apart from "Earlier Version of Windows" option and "windows setup" option, there was a third entry of "windows 7" as well. Is it the entry to the previous installation of windows 7 which i had deleted manually? My point here is that could it be that the damaged bootloader is still on my computer and whenever I try reinstalling windows 7 (fresh copy) the old bootloader is initiated again which is causing problems with the fresh installation? If it is so...I'd like to know where do these "bootloader files" sit on my computer so that i can manually delete them and make sure that they don't interfere with the fresh installation of windows? Please help me..i have been using Windows 7 for a long time and now its difficult for me to work on XP lol. Thanks!
