Can’t boot into Linux with dual-boot setup after BIOS update

Insert arch installation USB

Mount efi

And check this tool out

It will help you generate the missing entry

@hot wing Thank you for your response. Do I run this tool after chroot into the mounted drive?

Second.y when it asks for the efi partition do I give it /dev/sda1, the boot partition, or just /dev/sda

I’m not sure if this changes anything, but I have windows and arch installed on separate drives. Linux on /dev/sda and windows on /dev/nvme0n1. Both of them boot into windows 🤷‍♂️

If it worked in the past I see no reason it wouldn't work now

But grub might be easier to setup
