Which Linux distro are you using?
Arch
Which BIOS version are you using?
Which Framework Laptop 13 model are you using? AMD Ryzen™ 7040 Series
So basically I booted into the USB and successfully installed arch onto my SSD which I bought the 1TB one that framework offers, the WD Black. I chrooted into the install and installed and configured a couple things like network manager and grub. But when I reboot I get:
“Default Boot Device Missing”
In the boot manager the SSD isnt even an option
If you cloned or copied the os from one pc to framework you need to make sure the ssd is showing as mounter labeled, I’ve encountered same issue when i tried clonezilla my kali to my old laptop to fw13 as my ssd was mounted but not label even though kali was installed through clonezilla the boot drive was not mentioned also if grub has not been installed during linux installation it will show boot device missing so check that. I am using ubuntu with latest bios, amd 7840u
If you didn’t set up the EFI system partition or the NVRAM boot entry the firmware won’t know how to boot it.
