I've also tried to piece together advice from the Google Group and the Mac troubleshooting tips for Macbook Airs of a similar age and have got this far:
- Qubes 3.2 on a USB2.0 drive (not USB3.0)
- Booting from rEFInd first
When I boot from rEFInd and choose "Boot EFI\BOOT\xen.efi from ANACONDA" I get the four penguins and "efi: EFI_MEMMAP is not enabled" and "esrt: ESRT header is not in the memory map". Because the solutions for these problems require changing a lot of EFI options that Mac users don't have access to, I've decided BIOS booting is the way forward.
Again from rEFInd, when I choose "Boot Fallback boot loader from ANACONDA" I get the screen where one can choose to boot, check the media and boot or rescue a system. If I choose any of these the screen flashes and I'm dumped back at the same screen. This is also what I get without rEFInd
Last option from rEFInd - when I choose "Boot Legacy OS from whole disk Volume" I get what looks to be a typical GRUB boot screen (in blue, with the Qubes logo). "Install Qubes R3.2", "Test this media and install Qubes R3.2" and "Troubleshooting -> Install Qubes R3.2 in basic graphics mode" all result in exactly the same thing:
Loading xen.gz... ok Loading vmlinuz... ok Loading initrd.img... ok
And then nothing more. The cursor sits and blinks at me. Booting without 'quiet' as a command line argument also doesn't give further details.
Does anybody have any ideas or is there something I have overlooked?
This machine is more than capable of running Qubes (dual SSDs and 16GB of RAM). I'd hate to have to get a new machine just for running Qubes.
Any help or ideas hugely appreciated.
thanks!
