Re: Windows Startup problem :(
Well, try booting with the one that works. let's say it's the first choice. Then, go to Folder options and uncheck Hide system files and select View hidden files.
Then, go to C:\boot.ini.
Then, the first one in the list is the first OS in the list. if it's this one that worked, then, delete the two other entries. Save the file and reboot. It should work.
