sounds like a secure boot issue.

I just do clean installs anymore not a lot to do with Linux as vs Windows, Linux takes me like 30 mins to setup as vs Windows can take hours.

Android apps on flathub will be lovely.

any updates for wifi 7 drivers?

I use ZFS on my workstations with Debian, but yeah full drive is the way to go i think even Linux Mint does full drive anymore, also remember to keep backups.

I been using the open kernel driver with my Debian Workstation, it has worked better then the default driver by far with the Debian backport Kernel, I installed it using the Nvidia Cuda Repo.
