Windows volume label should be used

[Roger Binns]

When a Windows partition is detected it is listed in grub.cfg like this:

  "Windows 7 (loader) (on /dev/sda1)"

However the entry generated uses the volume id to find the disk:

  search --no-floppy --fs-uuid --set=root BA5435BA543579E9

This is very misleading since it means that instance of Windows will be used no matter which drive it is on. I had rearranged my drives in order to do some work and Windows was still booted much to my surprise. (The machine with the issue has 3 hard drives.)

I suggest using the volume label instead of the partition so the line would look like this since it is accurate (volume label is Mondo). It also helps when there is more than one Windows installation, when drives are moved around within or between machines etc.

  "Windows 7 (on volume Mondo)"
