install ubuntu alone on apple iMac (Intel)
Yesterday I've try to reinstall ubuntu on my iMac at the only difference is that I don't want to see mac OS any more as I never use it.
So I erase all partitions of the hard drive (including the EFI one)
set the HD as GPT and use the following partitions schema:
sda1 /boot ext4 200Mo
sda2 / ext4 25Go
sda3 SWAP 1Go
sda4 /home ext4 200Go
Then I install ubuntu 10.4 TLS
every thing went well up to the end where is told me installation successful and ask to restart.
But when I restart it give me this
e745...(cut)...0a2 end_request: I/O error, dev sr0, sector
I know that my iMac doesn't use a BIOS but an open firmware and I didn't create any EFI partition.
should I create one?
do I have to modify something in the Open Firmware?
and it it possible to install Linux ALONE on an iMac (intel)? as I don't want macOs on it nor rEFIt as possible.
