I was mistaken...
[QUOTE=johnsfine;3628758]Is there still someone looking for help in this long confusing thread that has been reopened several times?
The MBR is in the first sector of the hard drive. So taking away that hard drive would certainly take away that MBR and if that had been the MBR set to load grub, grub would no longer load. (If you had more than one hard drive, then what exactly was loading what might be a more complicated question).
I was mistaken to say that the MBR is not located on the HD, which it is, I have multiple HDs in my PC now, so grub is no longer need, simply chnaging the boot order works far better than grub.
Use this in Vista
use this in XP
Windows 7 Note
I am going to purposefully get a grub error in Windows 7 to see if the Vista commands work, I would not recommend anyone try this for fun... but I like to have fun.
