FT240 Posted December 9, 2023 Share Posted December 9, 2023 Hi all, my s740 won't boot from my usb sticks unraid partition. BIOS is set to default, partition shows up in BIOS and boot selection menu. Also, tested this stick on a windows PC, bootet without a problem. Any suggestions on where to start troubleshooting? I have almost zero experience. Thanks Quote Link to comment
itimpi Posted December 9, 2023 Share Posted December 9, 2023 Are you trying to boot in UEFI or legacy mode? Quote Link to comment
FT240 Posted December 9, 2023 Author Share Posted December 9, 2023 (edited) In UEFI mode. All other boot options disabled. Edit/ can't even find the bios option to switch btw legacy and UEFI Edited December 9, 2023 by FT240 Quote Link to comment
itimpi Posted December 9, 2023 Share Posted December 9, 2023 Have you made sure the EFI folder does not have a trailing ~ character? It must not be there to boot in UEFI mode. Does it even start the boot sequence (i.e. the blue Unraid menu), or fail later in the boot sequence. The fact you booted the stick on another machine does at least confirm the flash drive is potentially bootable. Quote Link to comment
FT240 Posted December 10, 2023 Author Share Posted December 10, 2023 EFI Folder is named 'EFI-'. Boot sequence doesn't start. After selecting the stick in the boot menu, screen goes black for a couple of seconds, then the boot selection pops up again. Any other ideas? Otherwise I'm just getting different hardware.

FT240 Posted December 10, 2023 Author Share Posted December 10, 2023 Yep that worked. Thanks a lot. Sorry, not a native speaker. Thought trailing character meant exactly this symbol '~'. Think it worked on my windows PC as that one is 12 years old and probably set to legacy, not UEFI. Quote Link to comment
