Under Win10 I burned the latest Iso to a USB memory using Rufus and I can boot off the USB no problem. This has an Aptio 2008 bios. When I try it on another laptop (the one I want it to run on of course) it freezes with a message
Could not open “\EFI\BOOT\fallback.efi”
This second machine has an Aptio 2018 BIOS and is a GeoBook.Any pointers?
Do you have a 2nd usb stick you can use? If so, I suggest that you boot the existing usb stick on the computer where it works and then plug in the 2nd stick and run “sudo live-usb-maker”. This will offer to clone your system to the new stick. The new stick might work better on the UEFI computer.
Too many notes
I imagine Rufus makes what is called a dd live-usb (or what I would call a dd-live-iso because the stick has the read-only iso filesystem copied to it) and some tricks are played (using hybridiso) to add a fat-32 file system so UEFI can read it and boot from it. But UEFI is generally pretty buggy and does strange things. If it boots Windows then it is assumed to be problem free. The cloned live-usb will be a “real” live-usb with read-write file system which might work better.
That error message shows up when you boot our dd-live-iso with UEFI. Normally the system will continue to boot and after that message flashes by you will get to the Grub menu. Our “real” live-usb boots slightly differently so maybe the problem that you had with the dd-live-iso will not occur with the real live-usb you cloned.
If you tell me the iso file you used, I will test here to make sure a dd-live-usb made from it boots via UEFI. Edit: The exact make and model of the computer that is not booting might help us see if other people are reporting similar problems on it.
The live-usb-maker clone mode is part of our strategy to get people to use live-usbs made with our software. We believe this is the best live-usb you can get. The Most Extensive Live-usb on the Planet! We have no control over other software that makes live-usbs and the whole “hybridiso” plus “dd” thing is a kludge. UEFI is a messy, buggy kludge as well with lots of system specific crazy bugs. If UEFI is not working right, you always want to test it on another, different machine. I’ve got 4 machines here I test on. The most expensive one has the wackiest UEFI bugs.
I also suggest that when you boot your existing live-usb you select the “checkmd5” option. This will verify that most of the bits written were written correctly. If an error is detected then it is possible there was also an error in the “dd” UEFI bootloader. You can do the same check on the cloned live-usb.
PS: our live-usb works with secure boot even though our installed systems do not (yet). You could try disabling secure boot anyway and see if that helps.
PS-2: Ninja’ed by christophe! Sorry christophe, I should have read your post more carefully before chiming in.
