@rzeta0@mastodon.social @itsfoss Normally you can disable Secure Boot and then any OS will boot.

A more secure solution would be to get a distro signed by MS (or a distro which signs everything using its own key and then add that key to your allowed key list in UEFI).

For most security, you could get a distro which signs everything using its own key, and then set UEFI to allow only this key and no other. This would prevent dual-boot with Windows though.
