I have a Lenovo ThinkPad P15 Gen 1 with Windows 10 Pro 64 pre-installed. I installed some time ago Ubuntu 20.04.5 LTS as a dual boot with grub on a secondary partition.

Now, I've some firmware upgrades left behind, at least 4 of them.

I want to upgrade them but I fear I'll lose the multi-boot and I'll not be able to login to Ubuntu anymore, and Ubuntu is my working environment, I use Windows for games only.

So, my questions are:

  1. Should I run the firmware upgrades from my Ubuntu installation or from the Windows one (the main default)?
  2. How can I recover my Ubuntu installation if, after the firmware upgrade, Windows will start automatically?
