I've tried using safe mode, to no avail. Additionally, the screen doesn't refresh; it leaves this information on the screen: > > EFI framebuffer information: > > addr, size 0x0, 0x0 > > dimensions 640x480 > > stride 640 > > masks 0x00ff0000 0x0000ff00 0x0000000ff 0xff000000 > > > I can actually use the menus, the system is responsive. However, I can only see the small portion at the top, which makes it impossible to actually perform the installation. Just a shot in the dark, but have you tried playing with the GOP commands in the loader prompt?: gop [list | get | set ] Hope it helps, Juan
