Hi,
Lubuntu 13.10 on Mac iBook G4.
I installed grub2 in order to boot into an older kernel (see this thread). To do this I followed the instructions here.
However, when I start the computer I get this error message:
"Invalid memory access at (code numbers)"
I am then dumped in Open Firmware.
There is a bug describing a similar issue here, and I have applied the suggested work around, but it makes no difference.
I can boot but only by entering Open Firmware and booting from there. Before installing grub it would automatically boot into Lubuntu.
Now I would like either to fix this so that grub loads normally, or failing that, remove grub. Can anybody please help me to do either of these?
Many thanks.
