Hi, I created a USB stick with a live version of Fedora 40. I tried both the default version and the KDE Spin. I tried using dd and using mediawriter. Same result: I cannot boot on the USB drive if my BIOS is configured in UEFI as it is to boot from my hard disk on Fedora 38. It says that there is no bootable drive. Note that I need a USB stick because I want to change my hard drive. I noticed that I can still boot F30 from an old live USB drive and you can see below that the output of dmesg is not the same for both Fedora versions. With the F40 image, I see an error: [ 1543.382799] GPT:Primary header thinks Alt. header is not at the end of the disk. [ 1543.382808] GPT:4484087 != 31129599 [ 1543.382810] GPT:Alternate GPT header not at the end of the disk. [ 1543.382811] GPT:4484087 != 31129599 [ 1543.382812] GPT: Use GNU Parted to correct GPT errors. I tried to boot with legacy BIOS and it works but then when I want to install F40 on the new hard drive, I have the impression it wants to install it for legacy BIOS and not for UEFI which I would like to keep. If there is another mean to install Fedora on a new hard drive, please share. I can plug the new hard drive as USB3.
