Package: grub-efi-amd64
Version: 2.02+dfsg1-10
Severity: important

Dear Maintainer,


   * What led up to the situation?
Installed Debian Buster on mdraid 1 (2 disks) system using debootstrap. Disks
are partitioned to allow both UEFI and legacy boot. Configured things in
chroot. Installed grub-efi-amd64 and grub-pc-bin package.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Ran "grub-install --target=i386-pc /dev/sda", "grub-install --target=i386-pc
/dev/sdb" to install grub in bios-grub partition, "grub-install
--target=x86_64-efi --no-nvram --removable" to install grub into efi partition,
done in chroot on laptop with disks attached via usb and mdraid started. Moved
disks to target system. Tried to boot up.

   * What was the outcome of this action?
System does not boot, neither UEFI nor legacy mode. GRUB drops to shell.

   * What outcome did you expect instead?
Expected to get to GRUB menu.

   * Workaround
Downgraded all GRUB packages to current Debian Stretch versions. No other
changes. Ran "grub-install ..." in chroot as above. Moved disks to target
system. Result: System boots fine in both UEFI and legacy mode.
Upgraded GRUB to Buster versions on running target system, reinstalled GRUB
(both legacy and efi). After that, system does not boot any more, as above.

   * Note
System information is not from affected server system, it's from the laptop
that's running reportbug.
