grub-pc vs. grub-legacy in Debian Squeeze

As you can see in the previous entry, I was running my old Compaq Armada 7770dmt laptop with its recent Lenny-to-Squeeze upgrade working well — except for one thing.

Grub2. Debian handled the upgrade well. It doesn’t remove the old Grub, now known as grub-legacy. Instead the old Grub gains an entry chainloading to Grub2, which is installed by the grub-pc package.

This way you can test Grub2 while still retaining Grub1. It’s a very nice way of doing what could be a system-breaking upgrade.

I can still boot from Grub1, but I can’t boot at all from Grub2. I made lots of temporary edits to the boot lines, but nothing I did enabled Grub2 to actually boot into Linux.

I’ll probably try again with Grub2; I wonder if a total reinstall would yield a bootable system.

But if things don’t start to break in Grub2’s favor, I’m perfectly willing to remove grub-pc and stick with grub-legacy.
