With every new operating system comes headaches as we find that our favorite programs or hardware no longer works with it. If you're like me, you're probably being forced into using Windows because everyone else does. Then again, if I had Linux installed on my box along side Vista, I'd feel a bit dirty and I'd be using a real boot loader like GRUB. In Vista Microsoft did away with the ntldr.exe and boot.ini files and replaced it with a new program.
