This was posted by Nicholas Geovanis <nickgeova...@gmail.com>, not by me. My suspicion is that the Lenovo Legion EFI BIOS intentionally creates directories and empty file "/efi/Lenovo/BIOS/SelfHealing.fd". I do not see much benefit in investigating this further. More riddling is the directory and file found after using the USB stick on the Lenovo Thinkpad machines. The internet says that "/System Volume Information/WPSettings.dat" is part of Microsoft services. So it might be that the USB stick got in contact with MS-Windows while or before it was plugged into the Thinkpads. If this suspicion can be excluded then i'd say that Thinkpad has some strange BIOS habits. What remains for Debian in this bug report is the observation that the integrity check of the Debian installation ISO says "Your installation media or this file may have been corrupted" when just a harmless change has been made in the filesystem of the EFI partition. Some special handling of /boot/grub/efi.img during the integrity check would cause less surprise to the user. Like: "Possibly some software or firmware made changes in the EFI System Partition. This may be considered harmless unless booting of this Debian ISO encounters difficulties or other files show checksum mismatches, too." Have a nice day :) Thomas
