Ok, im not sure if this is in the right forum, it covers topics of 7 and other operating systems so I'm hoping someone can help me. I wont explain why I want to do this, but for the general purpose, its for security reasons. I have a triple-booted computer. Meaning, I have Windows XP, Windows 7 and Ubuntu on a single laptop. I want to be able to hide 7 and Ubuntu. I know how to most of this but I am stuck at one point that I am asking for help on. I want to hide the windows 7 boot loader, unless I am booting the second partition (the partition reserved for win7). Basicially, unless i boot a specific partition using grub off a CD, I want windows XP to be the only recognised OS. I tried this by removing windows 7 from the bootloader, but it didnt let me boot into windows 7 anymore. Is there another boot way, or how would I make XP the default unless i say otherwise in the boot process?
