I think it's related to this. My guess is, when you installed 4.0, it overwrote the boot menu entry in your EFI firmware, so now it doesn't work for 3.2. If you were using legacy mode boot for 3.2, try to set that first in your boot order. If EFI mode, you might have to boot into Qubes recovery mode (possibly from the 3.2 DVD), then repair the EFI boot entry. The command will be something like: sudo efibootmgr -c -L Qubes32 -d /dev/sda -p 1 -l \\EFI\\qubes\\xen.efi Note the "/dev/sda" and "-p 1" might vary. "-p 1" is the partition number for your EFI partition (and this is what might have changed with your 4.0 install. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
