On some early, buggy UEFI implementations, you may need to disable EFI under Qubes completely.
This can sometimes be done by switching to legacy mode in your BIOS/UEFI configuration.
If that's not an option there, or legacy mode does not work either, you can try the following to add `efi=no-rs`.
Consider this approach as a last resort, because it will make every Xen update a manual process.

There is a [common bug in UEFI implementation](http://xen.markmail.org/message/f6lx2ab4o2fch35r), affecting mostly Lenovo systems, but probably some others too. You can try existing workaround:
01. In GRUB menu<sup id="a1-1">[1](#f1)</sup>, select "Troubleshoot", then "Boot from device", then press `e`.
02. At the end of `chainloader` line add `/mapbs /noexitboot`.
