I have a home-built PC with Gigabyte H370N-WIFI motherboard and two SSDs (the primary one with Ubuntu 20.04 LTS and another one for gaming running Windows 10). I want to be sure my PC will support Windows 11 in the future. When I run Windows health check to check compatibility with Windows 11, it tells me I need to enable UEFI secure boot. My question is - if I were to enable secure boot in BIOS would this affect my ability to boot Ubuntu?

    Turn on secure boot, upgrade and then turn off secure boot after. – David Oct 06 '21 at 14:20

    It might. The doc from microsoft https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/oem-secure-boot could include non-windows partition as "untrusted". If they want the could enforce a full recovery deleting any non-windows partition. – Rinzwind Oct 06 '21 at 14:54

    A lot of things like video drivers and virtual box will stop working if you enable secure boot assuming you haven't done the signing key thing. – Organic Marble Oct 06 '21 at 14:58

    @Rinzwind I wouldn't put it past Microsoft to change/delete Linux ext4 partitions... like they did with major Windows updates and MBR disks on single disk installations. – heynnema Oct 06 '21 at 17:03

I am using dual-boot system with windows 10 and kubuntu 21.04 (earlier ubuntu 20.04). I have enabled secure boot ON. Not facing any issues in booting either of the OS. I have one single SSD.
