Mandatory reinstallation?

Hello

Following a change of motherboard (old MSI B550 TOMAHAWK, new ASROCK X670E STEEL LEGEND) I can no longer access ARCHLINUX. I was in dual boot ARCH/WINDOWS. Now I have a systematic access to WINDOWS. In the bios, at the boot level of my motherboard, I only see WI!NDOWS.
Should I reinstall ARCH or is there another way?
If I have to reinstall ARCH it is not really a problem, only a waste of time .....

Just re-enable the NVRAM entry for ArchLinux, see: https://wiki.archlinux.org/title/Unifie … efibootmgr

Unless the partition where your Arch install was has been wiped or the filesystem corrupted beyond repair, there is never any need to reinstall.

Whatever tip you'll end up following, start by booting from the Arch installer. It's not only an installer, it's basically a live rescue environment.

Re: Mandatory reinstallation?

It should be possible to add a new entry from an Administrator prompt in Windows, for example:

bcdedit /create /d "Arch" {bootmgr}
bcdedit /set guid device partition=S:
bcdedit /set guid path \EFI\Boot\bootx64.efi

The first command should return a new GUID which should be substituted in place of guid in the other commands. The last command assumes $ESP/EFI/Boot/bootx64.efi to be the boot manager for Arch; mutatis mutandis.
