I can only repeat my
previous question which you didn't answered yet:
Can you list exactly what you had before and what you want now (both
physical and logical). This means I need to get 4 lists! a list "physical before", a list "logical before", a list "physical after" (how your HD's are hooked) and a list "logic after" (the driveletters in windows and their associates partitions)
(although the "logical after"-list has already been given in your posts: C:40, D:120, E:40, F:CD-RW)
And the bios setting can only be changed according to how your HD's are hooked up. Normally, your bootdrive is HD0 (IDE channel 0, master disk)...
