Newbie alert - it has been _years_ since I've tried to boot from USB - today I have tried two TW ISOs - first TW Rescue CD i686,
TW stopped bulding 32 bit since the beginning of April. It is now maintained in ports, although it seems to be stalled.
next TW DVD x86_64. Copied them to USB with 'dd'. Booting either one produces $SUBJ.
I tested openSUSE-Tumbleweed-DVD-x86_64-Snapshot20230420-Media.iso and openSUSE-Tumbleweed-LegacyX86-NET-i586-Snapshot20230403-Media.iso in QEMU with legacy BIOS presenting them as USB drive and both show boot menu. x86_64 image failed to boot rescue system, I had to manually select ISO partition as installation source then it worked. i586 image booted rescue normally.
Any hints?
Sounds like BIOS problem. The message comes from extlinux boot code that tries to read from partition. How exactly did you create USB?
