Installing Debian on secure boot blocked system

Postby woteb » 2017-10-11 16:01

Is it possible to install Debian on a system where secure boot can not be disabled. If so, how do you do that?

Dual boot with a distribution that does support Secure Boot (such as Fedora, openSUSE or Ubuntu) and use the other distribution to install and control GRUB.

Alternatively, use a "live" version of Ubuntu to install Debian with debootstrap [1] and then try the Linux Foundation's Secure Boot system:

I did have that working with wheezy but my UEFI laptop is no longer UEFI so I can't test it now.

EDIT: you could also try some self-signed keys:

Thanks!! It seems useful to me. I understand that with the admin password setting in the uefi settings it is often (read: not always) also necessary to enable / disable on secure boot.
