Update SB2 firmware #628

Closed deb75 closed 4 years ago

deb75 commented 4 years ago

Hello,

I have a surface book 2 bought in first quarter of 2018, for which I would like to update the firmware, especially the bios (or its equivalent). I guess I can only do that through windows 10.

However, I fear it messes the linux installation. I kept all windows partition except that I shrinked them to the maximum to make room for linux.

Currently, I run with secureboot disabled and I replaced the boot loader with ReFind which can launche either windows or linux.

I wonder if anyone has some experience in updating the SB2 firmware, how may I proceed ? Will I be still able to boot into linux after the upgrade ?

Thanks for your attention.

Regards

BIOS/UEFI updates shouldn't mess linux. Just go ahead and do them.

I updated my SB2 without Windows at all. fwupd can download and install for you. See the following for instructions:

Also, check the UEFI settings to make sure 'Boot configuration lock' is off, or it won't be able to boot the firmware update image.

Hi,

@chasecovello : thanks for pointing out this possibility. I had a look, interesting but I have too few time to perform carefully all steps, I fear I could mess or brick something. So at the moment, I will probably go through windows, hoping it will not mess anything, as tmarkov said.

Regards
