Can Debian be booted with Secure Boot enabled?

Hi,

Since users need to disable secure boot to install Debian but can you enable after its installation?

No. Secure boot prevents you from booting it at all. They may be a way around it (such as Ubuntu and Fedora have implemented) but it is probably best to leave it off (no real benefit)

I've heard that there's issues with using UEFI own bootloader on dual booting. They usually report one system booting and not the other. What different steps can it take to resolve this?

I have experienced this on one laptop with Windows and I have a workable solution.

Post a new thread with a descriptive title if this happens to you and I will post the solution so all can benefit.

How about posting it in the "Docs, Howtos, Tips & Tricks" section?

Are you saying that the UEFI bootloader should be able dual boot both systems?

I have one UEFI laptop triple-booting Arch, Debian Sid & Slackware64-Current and another laptop booting Windows 10, Arch, Debian Jessie & Slackware64-Current in EFI-mode and FreeBSD 10.1 in non-EFI-mode so it most certainly is possible

The only problem I encountered was when I installed Windows 10 in EFI-mode and the laptop defaulted to boot that automatically no matter what changes were attempted with `efibootmgr` (in GNU/Linux), `bcdedit` (in Windows) or from the firmware (BIOS) menu options.

My solution was to rename the /boot/Microsoft folder and write a gummiboot menu entry to boot the Windows bootmanager manually from the modified path.
