Maybe true back in those days. But these days that is not correct.
That's why I asked the OP what Brand of Mother Board he has. Fact is now
Win can be installed on the Primary IDE or SATA Port and then moved to
another on the same board **IF** the board in question Supports Boot
Selection from Hard Disks. Therefore Gruby Grub is not needed because
this is taken care of via Hardware.
Windows installer expects to see IDE0 or SATA0 and that is all MS wants
it to see during install because they think they are superior. For SCSI
Devices drivers are usually required.
