[Discuss] Help installing linux on I Mac

[Jerry Feldman]

I am not familiar with Mac hardware. Most Linux distros come with gparted.
While both fedora and Ubuntu use different installers, both installers now
use the gparted libraries, but different front ends. You can use both to
remove the partition tables, but neither are very user friendly. I think
Ubuntu comes with gparted on the live USB. So, from the live USB, just use
gparted to blow away the partition table. Or, from a terminal you can wipe
the first few sectors using the dd comnand. If done this a few times to
zero the MBR
dd if=/dev/zero of=/dev/sda bs=512 count=1
