Here's my setup. After I installed a new SSD, I have:

Grub is MBR on sda and set to boot from BIOS. I prefer to not change this; grub is much preferable as a boot manager.

I've run update-grub from Ubuntu and grub seems to be correctly configured as all options are available: I can boot any of the 3 Windows partitions and Ubuntu. I also ran the repair tool to get Windows to add both installations to BCD.

At present, choosing particular options seem to have no effect; the old version of Windows on sdc1 always boots. I don't understand what is causing this, but I can't figure out what. How does grub and BCD play along? I can't find any docs on this.

My thought was to only boot Windows off sdb1, and then let BCD do the rest (present a menu to boot between sdb2 and sdc1, but I can't seem to get BCD to boot sdb2), but this has been unsuccessful.

My configuration files:

Paste your grub.cfg file if using Grub2 or grub.conf file for Grub –  wbeard52 Jun 20 '12 at 3:10

Here's how to fix this issue:

  • Unconnect all your other hard drives
  • Try to boot your computer, get a cryptic error
  • Insert Windows disk, run repair

I haven't tried reconnecting my other disks yet, but I am sure Windows is using the SSD now!
