#1090321 — Bug#1004126: memtest86+.iso does not boot from USB

Package: memtest86+
Version: 5.31b+dfsg-2
Severity: minor

(Severity: minor, because the experimental version is affected)

I tried dd'ing the memtest86+.iso to two differen USB sticks. Both don't
boot on two different older ThinkPad Notebooks (one T520 and one X121e)
- the systems just fall back to the Boot Menu. The Free-as-in-Beer
memtest.iso from memtest86.com works fine on both boxes.

Greetings
Marc

memtest86+.elf on the same system runs fine if booted from an USB stick
with grub-pc (not grub-efi). Is that a possible indication that the
system doesn't run with EFI? I'd like to keep it running until tomorrow.

If you have /sys/firmware/efi on your running Debian system (with
either efivars or efivarfs kernel module loaded), then you're
running in EFI mode.

grub-pc doesn't do EFI boot, so I'd assume your system was booted in
legacy/compatibility mode then?

I can confirm that the X121e has its boot mode set to "Legacy only". The
T520 will be running the test until tomorrow morning.

The T520 is set to "UEFI/Legacy Boot: Both" and "UEFI/Legacy Boot
Priority: Legacy First".

I suppose your system runs with EFI, while memtest86+ needs 16-bit
boot and doesn't work with EFI systems, AFAIK.

thanks for test the package in experimental and report

the iso part should not be different from upstream except the the 
reproducibility changes (that I saw that was not working), today I did a 
small patch that make the iso with xorriso instead of cdrkit and a 
working change to make build reproducible (for now is only in git), 
tomorrow I'll do some tests with the iso if I'll have time

small note: makeiso.sh use the .bin that as already saw in some cases 
don't work correctly but the .elf yes, so in 5.31b+dfsg-1 I changed the 
default in grub2 from .bin to .elf (the iso instead remain with .bin), 
like what already done in ubuntu long time ago

today on the tests for 5.31b+dfsg-3 I saw that iso is working on cd but 
not on usb, looking at www.memtest.org "Pre-Compiled Bootable ISO" is 
the same but "Auto-installer for USB Key (Win 7/8/10)" produce a 
different content that I not found in source code from a fast look, I 
don't know how to change the iso to make working also on usb and in 
these days I don't have enought time to document me and do it (I want do 
something also on other packages I maintain and projects I support), if 
someone already knows and wants to do a patch when I'll have time I will 
test it

Control: found -1 5.01-3

the iso on usb pendrive not working is not "a regression" of 
experimental build, I tried older version I saw that have the same issue
