Can you change the MBR or install a bootloader INSIDE of xp? (remotely)

lol well thats the thing, can’t do it from here. (working inside of XP remotely right now)

BCDEDIT.exe, according to the boot.ini file, is supposed to be run to change boot options on vista. I’ll try running it from the cmd prompt in a second although I’m not holding my breath since it’s a 64bit os
