1.Format a USB drive as FAT32/GPT
2. Download the EFI shell ZIP containing the updated BIOS/Firmware for your model laptop
3. Extract/unzip into formatted flash drive
4. Make sure all the files are not contained within that first folder but located as the first thing you see when you open the USB
5. Boot from USB while laptop is plugged into power, specifically I would advise a “dumb” power supply like charging via a USB-A to USB-C cable, not a USB PD power supply
6. Profit
You can’t do this from within Linux, if you are asking how to format a drive within linux, there are many utilities that do this. I have KDE Partition Manager for instance. Other than that, I’m not really sure what “tips” are needed?
Which BIOS revision are you on currently? You can check from within the BIOS. Please be specific since the knowledgebase article mentions a requirement that you be on BIOS 3.17 to update using the EFI shell update
Below I have linked to downloads for previous BIOS revisions, you may install each EFI update using the same process as above. These are official links so don’t worry about installing some random BIOS software. I’d go one BIOS update at a time, starting from the beginning assuming you aren’t already on 3.17.
