Same error as before, only difference is that the option to boot Windows disappearedā¦ 
ok so chroot again nad reinstall the 5.17 kernel:
mhwd-kernel -r linux517
install again:
mhwd-kernel -i linux517
run this:
update-grub
and copy the output from this command here
In chroot, make sure to run the update again before going into more troubleshooting.
Boot from live USB and do
manjaro-chroot -a
then
pacman-mirrors -c Global && pacman -Syyu
then you can try to reinstall the video drivers again. This way you are sure you donāt have a mismatch of packages due to wrong mirror sync or something like that.

@omano ok i did that and uninstall:
sudo mhwd -r pci video-nvidia
install again:
sudo mhwd -i pci video-nvidia
Should I now reboot again or is anything left to do before?
windows is not being detected, very interestingā¦
now install also headers, since they were mentioned aboveā¦
pamac install linux515-headers linux517-headers
then run again:
update-grub
mkinitcpio -P
exit
systemctl reboot
Now it worked, thank you so much!!!
Only thing was no Windows in Grub, but after logging into Manjaro I did update-grub again and then it workedā¦
