Network Installation

USB Installation

It is possible to start an installation of Fedora 21 Alpha with out going through the steps of setting up a PXE server and rather initiating the installation through a USB drive formatted appropriately. To begin you will need the ISO.

wget FIXME

format the USB to use a GPT partition, with the first partition being 100M and formatted as vfat. the second using the remaining space (used 2GB USB) and ext4.

copy the EFI directory from the ISO to the vfat partition

edit grub.conf, change inst.stage2 to inst.repo (FIXME - ?)
