Ubuntu 14.04 dual boot 10.9(USB Install)

[izan2]

Hi everyone

Im new to the forum. Not very new to Linux but not a pro

Im trying to get the new 14.04 to load on my iMac 24" (7,1)

Any advice on how to if the SUPERDRIVE is not working anymore?

I've followed this thread:

Problem is the grub is designed for 9.04 and wont boot 14.04.
Maybe there is a new grub for what I need?

Do not know Macs especially with all the versions:

But Ubuntu uses grub2 which can boot in BIOS or UEFI mode. But Macs use an older version of UEFI so the install in UEFI mode is not quite as easy. And Ubuntu will boot from gpt drives in either UEFI or BIOS mode if you have an efi partition for UEFI or a bios_grub for BIOS boot.
Windows requires the hybrid MBR/gpt configuration which otherwise you want to avoid.

@izan:

What oldfred provided in terms of making a bootable USB would be your best option . . . I have yet to try using the USB option so I can't provide any insights on that. But, in terms of that thread, that was from '09 . . . which is "old" . . . the suggestion to try "rEFIt" might be pointing in the right direction . . . but, now it would be "rEFInd" . . . that would be installed in the 10.9 volume . . . and **might** be helpful to boot the USB system. I have a triple boot system on a MBPro . . . using rEFInd & GRUB2 ???? I didn't have to search around for some special GRUB, it's whatever the buntu installer uses . . . first try the install . . . if you have "free space" try using "install into largest free space" as your choice of installs . . . otherwise, you would need to manually partition the drive, providing a space flagged as "bios_grub" for GRUB, and then root/home, and then swap, etc.
