Hi All,
I am officially confused. Search.brave.com give tons of stuff I either can't use or can't figure out.
I AM NOT DUAL BOOTING WITH WINDOWS!!! (That is dumb to do. Use qemu-kvm)
I have a USB flash drive I have installed Fedroa 41 on. I somehow goofed my EUFI boot. Yes it was definitely my doing.
How do I fix my EUFI boot on the USB drive from my main fc41 computer?
The flash drive is completely readable from my main computer including the flash drive's boot folder
I am concerned that I my goof my main computer EUFI boot in the process.
Yours in confusion, -T
If it helps (from my main computer):

It's very unlikely that it is a problem with the USB drive. You didn't say where you're trying to boot it. But wherever it is, you will either need to select it from the UEFI boot menu or go into the BIOS and either set the USB as the primary boot or add the USB Fedora entry to the boot list. If you also have Fedora installed on the hard drive, this will likely conflict, although you could manually add it with a different name.

A different name is configured for Grub2 users in /etc/default/grub as a value for GRUB_DISTRIBUTOR=. You might use GRUB_DISTRIBUTOR="fedora41usb". That would result in a new directory on the ESP partition /EFI/fedora41usb/ along with existing entry /EFI/fedora/, and a corresponding new BBS hotkey boot menu selection of fedora41usb when booting with that USB stick affixed - upon application of your edit. Simply editing /etc/default/grub only changes the file. It takes effect only after it gets "installed" to the ESP and the UEFI BIOS. The specific procedure for that for a USB stick I don't know, but it should be discoverable in man efibootmgr.
BLS I haven't used yet, so I have no idea how to implement name change for its users.

That only applies if you have multiple Fedora installs on the same disk. I'm not saying there's a directory conflict. It's a UEFI boot entry conflict. The USB drive has its own ESP partition.

Can you show the fdisk output instead? It's more useful.

This stick is not configured for UEFI booting. Instead of a required EFI System partition (ESP) of 100M or more you have a 1M BIOS boot partition.

The ESP doesn't need to be too big, so you can probably take 200MB from the /boot partition to extend the first partition. Then you need to format it as FAT32 and flag it correctly (gparted knows how to do it). Then you need to install (or re-install) grub2-efi. Hopefully that will do it. You could probably copy the efi partition from another drive to get started. That might let you boot and re-install from the running system.

Do you mean you've installed Fedora so it can run from the drive (liveboot) if it can find it? Or do you mean you've copied the installer to the drive?

The flash drive is completely readable from my main computer including the flash drive's boot folder
With my last Fedora install (40), I had to use the server install ISO, because none of my systems could boot from that USB. It didn't matter if I used dd or one the mediawriter things.

I am thinking now that it booted legacy and I did not know any better.
I think I will dd /dev/zero the drive, then partition it GPT and see if the Fedora installer put EFI on it before configuring it. (I wrote down all the steps I want to configure it. It is just follow the steps.)

If it's a fresh install, then yes, just re-install it. Make sure that you're booting the installer in UEFI mode. You can probably disable CSM mode in the BIOS settings.

After the 3rd Windows 11 update in row left me unable to boot Fedora (40 and then 41), I dumped Windows 11 (I only have W11 it so I can report issues with PDF files in Adobe Reader to the authors) but had to use the Fedora 41 Server Installer (via ventory) as the F40 and F41 Workstation installers wouldn't boot.

If you need Windows and Wine won't cut it, run qemu-kvm. Dual boot is asking for a disaster.
Plus with qemu-kvm, you can run both simultaneously. Even copy and paste between the two
