I created a second windows 7 installation on a different drive. I have done multiboot before but always by booting from the installation disk. This time I ran the install disk from the existing Windows 7 installation, selected custom then the partition on another disk where I wanted the second installation. Ran with no hitches.
The surprise is that when I boot into the second install the drive letter of the system drive is not C: but instead is the same as it was as in the the original installation, which happens to be X, which I chose as a placeholder.
Is this normal behavior? I don't guess it matters except for the order in which drives appear in windows explorer. I doubt I should try to change the drive letter now.
In the past the system drive letter has always been C: for whichever system was booted. (I then changed whatever letter was assigned to the inactive system partition to x.y.or z to keep at the bottom of the list, away from the other drives..
