I just installed Windows 7, and I am running it in triple boot (Ubuntu/7/Vista). W7 boots just fine, and Ubuntu is fine, but when I try to boot vista all I see is a black screen, and then the computer resets. Does anybody know why this is happening/how to fix it?
Edit: My pimary bootloader is grub, however when I boot to windows it refuses to boot to either copy of windows directly. In grub, If I select Windows 7 it goes to the Windows bootloader, and if I select Windows Vista it gives me an error about no bootmgr(Boot Manager?) being present.
