Only the blind consider themselves infallible! ;-)

A good guess I'll agree as most likely...


Rather than using the BIOS boot sequence to select between booting a
particular drive, an alternative could be to always boot from grub on
his second drive. Add into the grub menu a selection to "chain" to the
MBR on the Windows drive to then go through the Windows bootloader
there when wanted.

A quick web search should give the grub details for chaining another
bootloader/MBR. (The MBR must be accessible regardless of the
fake-RAID.)


And welcome to the list. Such questions are a good part of what the
list and group are around for!

Good luck,
Martin
