6 You could try 'fdisk /mbr' from windows command line. That should
7 replace your MBR with one which simply passess boot process off to
8 the active partition, which is -- i believe -- how windows does it.
9 But, read on.

15 The boot process from a hard drive looks something like
16 Power button -> BIOS -> mbr boot -> partition boot -> OS init.
17
18 chances are that GRUB is on the mbr so the recovery partition's boot
19 record is never used. Have you considered using GRUB to boot the
20 partition like you would a windows partition? that would look
21 something like
22 | # boot this partition's boot record
23 | rootnoverify (hd0,2) # corresponds to 1st hard drive ,3rd partition.
24 | # set to your recovery partition instead.
25 | makeactive
26 | chainloader +1
27 that, I think, will do about the same thing as 'fdisk /mbr' from
28 windoze but avoids the hosing of GRUB, which is actually a wonderfully
29 flexible and useful bootloader compared to the 'active partition'
30 scheme of windoze.
