Dear Paul,
I have a Lenovo x230 i5 and I wold like install the Qubes.
I have a bootable USB with 3.2 but i have a problem.
I saw this
https://www.qubes-os.org/doc/uefi-troubleshooting/ but I am not sure how can i do that? Where I have to edit the xen.cfg file? What I missed?
Edit /mnt/sysimage/boot/efi/EFI/qubes/xen.cfg (you can use vi editor) and add to every kernel section:
mapbs=1
noexitboot=1
Note: You must add these parameters on two separate new lines (one paramater on each line) at the end of each section that includes a kernel line (i.e., all sections except the first one, since it doesn’t have a kernel line).
Now you can reboot the system by issuing reboot command.
