Hi there, welcome!
I think you could try the following procedure:
- use the USB and from there chroot into your system
- run
sudo micro /etc/mkinitcpio.conf
- add the module
vmd
to the MODULES list - run
sudo mkinitcpio -P
to regenerate all initramfs - run
sudo micro /etc/default/grub
- add
nvme_load=YES
toGRUB_CMDLINE_LINUX
line - run
sudo grub-mkconfig -o /boot/grub/grub.cfg
to regenerate the GRUB menu - reboot
If you don't know how to chroot, there is a tool for that in the live USB or a tutorial in the forum to do it "manually".
