I have installed ubuntu on my Air and have it running for over 6 months now. Today I run a software update and grub wanted to update and I selected it to not change anything / update and well it did! rEFIt was installed.
Now when I reboot I have no chime on boot, when I hold OPTION it does nothing and goes straight to GRUB. I have no way of getting back into OS X. Also the Air doesn't have a DVD drive so I can't put any disks in.
As I can't access the boot selector when holding option I have no way of booting a USB.
Anyone have any ideas?
Thanks in advanced.
