All, I'm in a wierd situation, I would like to use grub2 to boot my Ubuntu, Windows 7 (old) and Windows 7 (new).

I purchased an SSD and installed Windows on it. My old Window installation still exists and I would like to keep it around for the next few months as I figure out what I need to copy over from it.

I currently have:

  • /dev/sda - disk drive -- part: 1 (linux), 2 (swap), 3(old windows), 4 (NTFS Data)
  • /dev/sdb - SSD -- part: 1(new windows)

I would like grub2 to display seperate entries for:

  • /dev/sda3
  • /dev/sdb1

However it only displays /dev/sda3, this leads to the Windows Boot Manager, and there I can choose which Windows to boot. I've been trying to figure out how to adjust this, but I can't seem to figure out where to start.

Points of Interest:

  • /dev/sda3 is listed as Boot, Page File, Crash Dump (notice Boot is here!?)
  • /dev/sdb1 is listed as System, Active, Primary (this is weird?)

Have you tried adding a menu entry manually? – Wolfizen Aug 19 '13 at 2:27
I have not, I am confused on what entry I would even add. Excuse me if I use the wrong terminology, but it feels like Windows has set itself up to be chain loaded. I don't know if I can boot my new windows partition directly. To reiterate, I don't think there's anything even written to the boot of sdb. Disclaimer: I suck at bootstrapping, I'm probably entirely incorrect. – Constantin Aug 19 '13 at 2:34
How did you install Windows on /sdb ? – Wolfizen Aug 19 '13 at 2:40
Windows7 Dvd. SDB was brand new, no other partitions. The DVD overwrote my MBR on /dev/sda. Today I booted into a 12.04 Live Disk and reinstalled grub into the mbr expecting to see both installations. – Constantin Aug 19 '13 at 2:44
But.. how did it install. Are you sure it only installed 1 partition? – Wolfizen Aug 19 '13 at 2:46
