Prior to installing OS Selector my developer machine had several XP, one Win Server 2003, and 2 Vista OSs, all booting from small active FAT (Disk 1-1) with no OS of its own. After OS Selector, all but Vista boot directly from Selector. Of the 2 "Unknown OS" selections also available, the first returns me to the old Vista multi-boot selector. (The other just fails.) I have tried to mark both Vista OSs as bootable, but am told by Selector they are not. I assume I may need to copy some files from the FAT to make them so, presumably from the FAT's hidden BOOT directory. But what files and how to place them on Vista OSs? Or is there another way? Also, is there any way to get rid of the unnecessary "(English)" notation appended to name of each OS in Selector? Thanks.
