Hello I'm new with this dual boot thing. I got a problem with some boot, I'll hope you can help. Here we go, my problem is, that i got Vista x64 installed (C:\), then I wanted to install XP Pro (E:\). The XP Pro installation is installed on a partition on a seperated drive (D:\). Hope you understand what i mean But when I finished my XP Pro installation it booted okay, and everything. But then when I would boot Vista, it wouldn't work, I have now formated my Vista installation still on C:\ (It was nevertheless about time to do that). But now when I boot XP Pro, it comes with this error: Invalid BOOT.INI file booting from C:\windows\ NTDETECT failed I have searched around, on the neosmart forum and wiki, but havn't found anything working yet. Thanks!
