Hi, > You are a wizard Thomas,
I lurk at boot loader mailing lists since more than a decade. But as sysadmin i am lame enough to not knowing how to make ASUS ProWS C246-ACE EFI firmware 1401 offer me any external storage device for booting, or how to disable its Secure Boot setting. I will have to ask the provider of the machine how he installed a Debian 10 base system to it a few months ago. (It will be my next workstation. But due to some hardware flaws i began to use it for kernel experiments. Now the flaws are gone and i should invest more time into accomodating it to my oldfashioned window manager desires.) > -boot_image any mbr_force_bootable=on > makes the cloned USB drive work both in the HP Elitebook 8560p and > the Lenovo V130 :-) That means we should ask Steve Langasek to add option --mbr-force-bootable to the xorriso -as mkisofs command that is used for ISO production. Then the waiting for complaints will begin again. >From comment #12: > A solution would be to revert to the boot structure of 20.04.x LTS, That would mean to revive ISOLINUX as BIOS boot loader. I assume there were compelling reasons to switch to GRUB for that job. (My current theory for Lenovo V130 is that its firmware recognizes ISOLINUX isohybrid and then drops its usual demand for valid GPT. The V14 could have the flaw that it offers to disable Secure Boot but nevertheless fails if no Secure Boot signature is found. I am not aware that we got confirmation that V14 boots with old Ubuntu ISOs. We have a report in #176 of 1886148 that Manjaro and openSUSE fail.)
