Changing boot order - Grub error 17 / removing grub
New to these forums, hope somebody on here can help out as I'm at a bit of a loss.
Hopefully I can explain my problem clearly enough on here.
I am upgrading a system to have encrypted disks, it's a two disk system, so I want the BIOS to look at /dev/hdb first to unlock it, then it should reboot, see that isn't a system disk and try to boot /dev/hda. Then that gets unlocked, and the system boots.
After unlocking hdb I get a Grub error 17.
I can't edit Grub to look at hda as on normal boot it hasn't been unlocked yet, so it can't see the file system at that point.
I reformatted an old XP disk as hdb, and it worked fine, but I'd rather not install windows every time, just to reformat it as ext3.
Is there a simple way of clearing the boot sector of hdb?
