Do you have a system that should support Windows 11 but are still getting "this pc must support secure boot" error? Its probably because your system is setup to MBR. In this video Ill show you haw to use the MBRtoGTP command to fix it so you can install Windows 11. CAUTION: I may not have been clear in this video. This method ONLY works if your system already support's UEFI but for whatever reason has an MBR disk. If you have an older BIOS that doesn't support UEFI your system will not boot if you follow this guide. If you have already followed the guild and your system is not booting I'm currently working on a video to show you how to fix it. It might be a couple of weeks before I get it done but when I do I will post the link in this comment. Sorry for any confusion.
