I have an old disk with two bootable partitions, WIN 98 partition 1 and WIN 2000 partition 2. When I boot that drive, WIN 2000 boot manager menu comes up. I copied both partitions to a new disk. Only WIN 98 boots. I think the new MBR is setup only to see WIN 98, since I didn't install WIN 2000 on the new disk (just copied its partition). I could probably re-install WIN 2000 in recovery mode, to get back the boot menu. That's time-consuming, as I have to re-do all the updates. I could use Acronis boot manager, but prefer not to--fewer boot managers to deal with. Is there any other quick-to-do option to fix the MBR to dual boot the new disk. I expect that copying the old MBR to new disk is not polite.
