My dad installed Ubuntu 12.04 on his Macbook Air as a clean install, and it worked great at first, but I recently began to work on it (upgrading, updating, installing, and fixing some bugs), and eventually had to restart it. That is where I encountered some issues:
When booting, I had to hold the "Option" key to boot Ubuntu, because he deleted the Macintosh HD, and the EFI was attempting to boot that, but couldn't find it. Thus, it gave only a white screen. The problem can be easily solved by holding the "Option" key and selecting the drive, like I mentioned before, but that can be tedious when booting.
Next, there is another problem: sometimes even when booting the BIOS, it gives only a purple screen without allowing to select an OS. So far, the booting process is a tedious string of holing "Option," selecting the drive, holding "Delete" to load the BIOS, and finally selecting Ubuntu. I don't want my dad to have to go through that every time he boots.
My main questions are as follows:
First, is there a way to scrap the EFI and boot directly to BIOS in Ubuntu? Or maybe just set the EFI to automatically boot to BIOS?
Second, can I set BIOS to automatically boot to Ubuntu? If so, could I still be able to load it up by holding Delete when needing to access the recovery disk?
