Will Ubuntu 20.04LTS boot a computer configured for UEFI secure boot?

co flag

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.

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.

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.

@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.

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
