Matthew Garrett investigates
the subtleties of booting Linux with EFI. Once again, hardware vendors are myopically focusing on Windows.
"As we've seen many times in the past, the only thing many hardware vendors do is check that Windows boots correctly. Which means that it's utterly unsurprising to discover that there are some systems that appear to ignore EFI boot variables and just look for the fallback bootloader instead. The fallback bootloader that has no namespacing, guaranteeing collisions if multiple operating systems are installed on the same system.
It could be worse. If there's already a bootloader there, Windows won't overwrite it. So things are marginally better than in the MBR [Master Boot Record] days. But the Windows bootloader won't boot Linux, so if Windows gets there first we still have problems.
