Hello, I just used clonezilla on a secure-boot enabled dual-boot setup that was working fine. I imaged my ubuntu 20.04 partition to a data drive, and after doing so, got the following error trying to boot back into the partition I just imaged:

error: /boot/vmlinuz-#### has invalid signature
error: you need to load the kernel first

I believe this is secure boot related and I know I can probably just disabled secure boot (I will try this tonight), but it is concerning that Clonezilla would cause alterations to my bootloader just by imaging it. Perhaps I did something wrong, this is the first time I've used Clonezilla in a while, but I did make sure to use the alterantive ubuntu amd64 flavor Clonezilla live.

Please ignore this, i messed with the boot order and it solved it in bios. I don't know how to delete this post....

Thanks for sharing that. They can be kept so that others can refer to if you do not mind.
