I had a vista home installation that I added a hard drive to and installed xp pro after i disconnected the vista drive. I guess I realized too late that the bootloader has to be on both drives to be able to have a dual boot that will work. How do I get the xp pro installation which boots up if both drives are connected, to recognize the vista drive? The vista install will only boot up if the xp pro drive is disconnected.
I got as far as copying the boot.ini, ntdetect.com and ntldr files from the xp drive onto a usb drive and I copied them to the vista drive. I put them in a folder on the desktop and it took a while to be able to access them since they were hidden system files and vista in it's security minded wisdom did not want me to be able to see them. i set the folder options to view hidden and system files and now they are visible.
Should I copy them to the root folder of the vista drive before I get the OS to actually recognize that there is another drive in the machine or should i somehow do that first?
If so, how do I do it? When in xp, I can't see the vista drive, and when in vista I can't see the xp drive since it won't boot into vista with the xp drive connected.
Help, please!
