Partitions properties window
7.7.4 Disks
Generally, Windows can boot from HDD only if its boot files reside on the first (according
to BIOS) hard disk (see details in 8.2.1 "General information"). If you connect a live
system HDD, taken from another computer (where it was the first disk), to your
rd
computer, where it becomes the second (3 etc.) disk, boot from that HDD will be
impossible, even if the hardware is identical on both computers. OS Selector can manage
situations like that and automatically set the disk order required for booting the selected
operating system.
