Lenovo firmware upgrade on Ubuntu, how to not lose grub multiboot

eg flag

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?

Thanks!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
