Work is ongoing on making this easier for Linux distributions, and all Linux distributions can support Secure Boot-enabled PCs with a bit of work already. ![]() ![]() ![]() Matthew Garrett pledged to work on combining the Linux Foundation’s solution and shim to create one standard boot loader all Linux distributions can take advantage of. The Linux Foundation has released its own Secure Boot solution, which other Linux distributions would be free to use instead of shim. Some other smaller Linux distributions also use shim. They use a small “shim” boot loader signed by Microsoft, which in turn confirms the main boot loader was signed by the Linux distribution before loading it. Modern versions of Ubuntu, Fedora, openSUSE, and Red Hat Enterprise Linux all “just work” without disabling or configuring Secure Boot. But, in practice, most PC manufacturers do install this Microsoft key.įedora shouldn’t have any problem installing on a system with Secure Boot enabled. PC manufacturers aren’t required to include the Microsoft key for third-party UEFI applications as part of the Secure Boot specification, which means that these Linux distributions may not actually work on all Secure Boot PCs. While Microsoft does sign Linux boot loaders with a Microsoft key, these boot loaders are signed with a separate key from the one Microsoft uses to sign Windows. The handful of Linux distributions that take advantage of this should boot with no problems and no further configuration on a PC with Secure Boot enabled. Microsoft provides a signing service Linux distros can take advantage of, allowing them to boot on most Secure Boot-enabled PCs with no further configuration. These PCs ship with Microsoft’s keys preinstalled, so they’re effectively checking Microsoft has signed the boot loader before allowing it to boot. PCs with Secure Boot check that the system’s boot loader is signed by an approved key before booting from it.

Some Linux distributions have had their boot loaders signed by Microsoft so they’ll boot with no problems. ![]()
