Mine's an E430. An update, I toggled the hybrid UEFI/Legacy to allow either, otherwise I'd have to reinstall windows. The only side effect so far is that I borked grub in my dual boot as it can seem to boot windows anymore. The BIOS boot menu lets me bypass directly to the windows partition so it still works I just need to redo grub.
So changing boot type on a dual boot is likely to bork boot loaders. I do not know if it causes problems on a windows only UEFI machine.
