On my MacBook which now has a hybrid GPT/MBR partition table, installing Ubuntu 7.04 (choosing i386 edition even though the processor does have 64-bit capabilities) from the CD, generated an incorrect /etc/fstab file. The partition named "EFI system partition" (without the quotes, and this name already existed on my disk) was inserted in the fstab with the spaces replaced with tabs, the field separator in the fstab. They should not be replaced. Also I had earlier made a fat16 partition myself that I put grub2 on, and (in parted) changed the name to "GRUB2 bootloaders" (again, without the quotes) and that line in the installed Feisty's fstab also had the same problem. (Not that I want those entries in my fstab, unless they have noauto, which they don't!)
P.S. I didn't want it to install GRUB Legacy, so I customized it to get an error in the install (I changed (hd0) to (hd5,8) which doesn't exist). Why is it a _fatal_ error when grub-install fails (and is there anything important in the installation process that comes after that?)
Thank you for taking the time to report this bug and helping to make Ubuntu better. If possible could you please add the log reports as indicated at https:/
