Howdy, I asked about this in a thread recently but can't find it now. Not sure why because it wasn't that long ago. In that thread, I was asking about deleting /boot/grub as it was used for the old grub, not the new and improved monster sometimes referred to as grub2. I think it was Neil that suggested just renaming the directory to grub.old. Thought that was a reasonable suggestion so that's what I did. Dang, Neil gives some seriously good advice plus he has those nifty signature lines. ;-) I had some kworker process that just wouldn't go away and was using a good bit of CPU time for some reason. I decided to reboot to reset that and guess what, grub puked all over my keyboard about a missing file. Anyone care to guess where that file lives?
TLDR, skip to last paragraph. After the nasty puking job, I had a grub rescue prompt. No freaking clue what to do so out comes the cell phone and a bit of googling. Couldn't figure it out so I dug around and found a old Knoppix DVD and used that to boot with. I used the mv command to rename the directory after starting lvm, mounting stuff etc etc. I wanted to reinstall grub but had issues using chroot. Anyway, I rebooted and grub worked. Of course, I recently updated to a new kernel, it got about 2 seconds into the boot up and it puked on my keyboard with a panic. Reboot again and use previous kernel, anyone not understand why I keep backup kernels? ROFL Now here's the kicker. After getting booted up with the previous kernel, screen 2 on my video card wouldn't work. That's my TV screen. I ended up having to do a complete power off, what some call a hard reset. Rebooted witha working grub, a known good kernel, that can find all the files it needs, and my second screen comes up. Should I reinstall grub after removing the old directory so it puts things where it needs to be or what? Or does a new install have that old directory too? While at it, is there something that can give me better options in cases like this or do I need to stop renaming stuff? The reason for the post is the above questions and this. If you have a old grub directory in /boot, do not delete or rename that until you know grub has all the files it needs elsewhere. It will get upset and it won't do you any good either. Right now, I don't have to wash my hair, I can just polish my head. I pulled out a lot of hair dealing with this and I'd rather no one else had to. Dale :-) :-) P. S. Since my old system rescue CD didn't work, I think it's scratched, I'm off to make some rescue options, sysrescue and Knoppix too, just to be sure.
