The eval is the same installer as the normal one, it isn't picky about hardware. Erroring before setup appears is nearly always how the USB was made. Old PC, so write it with Rufus and choose MBR with BIOS or UEFI-CSM, not GPT/UEFI. Make sure you grabbed the 64 bit ISO only if the CPU supports it, old machines may need the 32 bit one. If you get an error code, post it, a 0xc000000f type error points at the USB, a message about NX or PAE means the CPU is too old for 10 full stop.
