I have a dual booting Vista/7 pc, and so far everything works fine.....I just choose the OS I want to use as the pc starts....what else would I desire more...... Well, I am not completely happy now. Initially I had a single drive with Vista installed, and then, I added a 2nd HDD and installed Windows 7, but since the vista drive was set as the primary drive in the BIOS, the boot loader or whatever it is called, was saved in that drive. Now the problem lies with the fact I cannot unplug or remove the vista drive because the drive with Windows 7 won't load at all. Could someone share some light regarding this issue? is this boot manager a single system file that could be easily modified, copied, or created in the Windows 7 drive?
