I installed Ubuntu (Precise) on my Macbook Pro but now I'd like to go back to OSX but I can't boot off the OSX Snow Leopard DVD to do a reinstall. I have tried booting and holding down "c" or using "Option" and then selecting the OSX install media but after selecting the OSX media the grub menu loads and tried to boot Ubuntu instead of booting off the DVD.
I tried booting off my Ubuntu LiveUSB and removing all of the partitions using gparted but the problem still persists. Any ideas? I just want to wipe everything and go back to OSX only. When I installed Ubuntu I pretty much followed the default options.
