I try to setup Linux on a MacBook (13in, mid 2009). I created an Ubuntu Live USB stick (ubuntu-13.04-desktop-amd64+mac) and installed Refind (0.10.8). Booting into the live environment works, also creation of the partitions with gparted. But as soon as the swap partition is formated with linux-swap the computer hangs at the next reboot: Refind lets me select the Ubuntu Live USB, but instead of the Ubuntu boot menu only a blank screen with a blinking cursor appears.
The reason for this behavior is definitely the creation of the swap partition. As long as the partitions are formatted differently (HFS+, FAT32, ext3,..) the boot menu appears immediately. I tried different suggestions I found (e.g. press Shift or Escape) but without any effect. Solutions with different boot options are useless because I don't even see the boot menu.
Any ideas what could cause this problem?
