Groovy to use GRUB2 for booting installer media in any modes on all architectures

Just for the record - I test groovy-desktop-arm64.iso on Lenovo Yoga C630 WOS and it does not boot.

When I write iso by using usb-creator-gtk then laptop firmware does not detect flash drive as bootable device and just skip to GRUB2 from UFS.

When I write iso manually, by coping content of both partitions from iso to FAT32 partition of flash drive I getting following behavior:

  1. Flash drive led blink
  2. Black screen
  3. Noting happens, it’s just sits here

It’s seems like GRUB2 from iso get started but then it freeze for some reason.
