I have reinstalled my 11.1 to 11.2 and the new version is not booting. I selected install instead of upgrade (to make sure everything will work), but obviously it was a wrong choice.
I’m using software raid (mirror) and the system installs correctly, but simply won’t boot (11.1 worked just fine with exactly the same disk/paritition/raid layout).
Won’t boot = grub starts correctly, after one of the items is selected (both normal and failsafe fail) it prints the boot line (kernel (hd0,0)/vmlinuz-2.6.31.5-0.1-desktop root=/dev/md1 resume=/dev/md3 splash=silent quiet showopts vga=0x346) and nothing happens.
md1 is my root, md3 is swap, boot is on separate md0
First, the installation does not like having master boot record written to a different disk, then where the /boot resides.
Second the configuration of grub is installed incorrectly (hd0,0) instead of (hd0,1) (actually I have no idea why it is (hd0,1) when grub should be counting from zero).
There’s a section in Release Notes about needing to check where the Boot Loader is writing things. There have been some bugs reported, affecting ppl with previous Linux installs.
I have tested 11.2, with /boot on a different disk to my boot disk, but then I make sure it installs GRUB in the /boot partition, and keeps well out of MBR because that would interfere with the past ‘stable’ installation. I would have had it write Generic MBR, because the disk it install to has Windows Vista & 7 on it. It successfully avoided breaking MS install & boot, which was a main concern for Linux Install on 2nd disk.
Having had to recover my 11.2 install after having thrown an 11.1 on the same disk yesterday, I am thinking an ‘expert mode’ where you can STOP GRUB being installed anywhere, just having Boot loader generate sample menu.lst file would save troubles.

Thats exactly what you can’t do when you are using RAID setup.
