I intended to keep this short, but with so many baffling things happening I did not succeed. Please bear with me.
GF's machine (which I adminsiter) is an AMD Sempron(tm) 2400+. No proprietary graphics or drivers in use. Background: I started long ago with Lucid. Last month I upgraded it in stages to Maverick and then Natty. Mostly trouble-free upgrades, though I had lots of trouble getting the Plymouth splash to work. (It all works now.)
The onboard graphics card is nothing special, so only the basic graphics capabilities ever would work. So when I got to Natty, the new Gnome look didn't work and it reverted to the classic layout.
From another machine I downloaded the Torrent "alternative" Oneiric ISO for i386. Put it on a USB stick. It would not boot this system. The menu came up, but the efforts to select Oneiric to try or to install did not work. So I burned a CD from the ISO. It would not boot this system. It gave an error message that I was trying to load a 64-bit kernel. Well, gee, I was sure I'd burned the i386 image to the CD (though I also had downloaded the x64 ISO for my own machine). But I decided I must have burned the wrong image, so I burned a second CD. Same thing!
So now I was pretty annoyed and I started the standard update to 11.10 from the Natty Update Manager. Three hours later, it seemed to have worked (I did see dozens of ssh-cert errors flash across the screen, but didn't get too worried at those). Update Manager proclaimed success at the end, so I rebooted.
Grub2 failed! I have several other bootable partitions on this machine, by the way. I knew I would eventually get something booted, but this failure was a huge surprise. I was at the grub-rescue> prompt, but no commands I could think of to try produced anything useful.
I found an old grub-boot rescue CD I'd burned 1.5 years ago and ran it. (It runs old grub, but that's just a side-note.) Many of the things I tried from the boot menu didn't work, but eventually I got into an Oneiric rescue shell. I ran update-grub and grub-install and tried again, but grub (new) still would not load.
I re-loaded the grub-boot CD and eventually got into another bootable Linux partition and installed grub. That worked, and now I found out the next crazy oddity.
Now I had a normal grub2 menu, but Oneiric would not boot. It said "missing license" or something! On further inspection, the 3.0.0-12 kernel was nowhere to be found, although I thought I had watched the Oneiric update put it on the hard drive. Just completely gone! MIA.
So I booted to the previous kernel, i.e., Natty, and everything looked entirely normal -- except the message about Oneiric's having been released and don't I want to upgrade immediately? came up. WTF?
So anyway, I re-ran update-grub and so on. Everything seemed fine, so I rebooted. Grub still worked (whew!), but the Oneiric kernel was definitely MIA.
So now I went back to my other computer and burned one more i386-alternate CD from my ISO. I put it in this (GF's) machine, but it would not boot. It didn't give the old error message about a 64-bit kernel, though. But I could not make it boot.
So I rebooted to grub again, went to the previous version (Natty) from the menu again, started the boot, and walked away from the computer. Well, when I came back, I was looking at the Oneiric login screen! My jaw actually dropped.
I logged in to Oneiric, opened a terminal, and ran uname -a. It was running the Natty kernel. But it said it was Oneiric. It looked like Oneiric (I have it on two other machines). Another thing: the Dash stuff worked. Remember how I said Natty wouldn't load the new GUI and reverted to Classic? But Oneiric loaded Dash fine with this cheap old onboard graphics card.
Okay, I looked in /boot and saw there really was no 3.0.0-12 kernel to be seen. I opened Synaptic and installed the "pae" set, since it was recommending itself in the description text. I re-ran update-grub and it listed the 3.0 kernel and also the 3.0-pae kernel.
Now I took out the CD and rebooted. Can you guess what? It said the 3.0 kernels weren't found. I went back to the "previous version" again, but this time Natty booted. Natty, with the old, classic user interface. Oneiric was not to be found. The kernels I had installed were there in /boot, though.
So I put the Oneiric CD back in and rebooted. (Again, the CD won't load directly.) At the grub menu I still could not get into Oneiric with the 3.0 kernel: neither 3.0.0-12 nor 3.0.0.12-pae. Again I went to "previous version" (i.e., Natty), but now the Oneiric CD was in the bay again. It booted to Oneiric again, but still with the 2.6.38-11-generic kernel from Natty.
And that's where I'm typing this from. Everything works, but if I take the CD out of the bay and reboot I'll be back in Natty again, not Oneiric. (And the grub menu items pointing to Oneiric won't work, and GF will be flummoxed.)
Help?
