I've dd-ed the boot-grub2-f36.iso to an USB stick and successfully tested it on the following machines: 1. Siemens PC with an i5-2400 with 8G RAM 2. Fujitsu-Siemens PC with a Core 2 Duo E6600 2.4 Ghz dual core with 4G RAM 3. Dell Latitude E6400 (core 2 duo) with 4G RAM 4. Acer One AO532 netbook with a N450 + 2G RAM The image booted fine on all 4 machines, so from a machine compatibility pov this looks good to me. There were 2 minor issues with machine 2: 1. After the "Welcome to GRUB" text the 3.5" floppy drive was searched repeatedly before showing the grub bootmenu. It also took like 5-10 seconds to show the menu. I guess that grub is using a minimal grub.cfg which is looking for the actual grub.cfg based on the partition uuid or some such and it is also checking the floppy drive. I wonder if we can tweak grub.cfg on the bootmedia to not do this? 2. Booting the kernel once making the selection in the menu takes forever (I walked away after 1 minute). But it does boot eventually and I just tried with a Fedora 36 nightly, thus using syslinux and the same happens. I believe that the USB stack of the BIOS on this machine simply is terribly slow and reading the big kernel + ramdisk files one sector at a time. So there is nothing we can do here. Since this also happens with syslinux this is not something to worry about.
