0005 & 0009 are both fedora.. same UUID, hd(8..
Both of those entries identify a boot loader located on the same partition. Everything before "/File" is part of the device path.
how do you boot different files shim vs bootx64..
I'm not sure how to make that more clear than it is. You have a FAT32 filesystem which contains many files. One of them is \EFI\Fedora\shim.efi, which verifies and loads grubx64.efi. The other file is \EFI\BOOT\BOOTx64.EFI.
When you select a boot option from the UEFI menu, or as a result of searching the list for a valid boot loader, the firmware will load the file into memory and begin execution of whatever code is in that file.
