I've tried and tried every method I can find about creating a bootable USB drive running Ubuntu (used the Ubuntu website method, downloaded EFI files and put the ISO file as boot.iso on the FAT formatted USB drive, downloaded packages that claimed to be complete, everything I could find) and I still can't figure out anything about how to get this to work right. My Specs: Macbook Pro 5,1 8GB RAM, rest factory. Has Lion installed as primary OS and a Ubuntu VM (that I hope to be able to delete and replace with a USB Boot Drive with Persistance Mode) and Downloaded Ubuntu 11.10 64 Bit version. My flashdrive is a 32GB Attaché model. Can anyone help me please? Thanks!!
