you dont need to use chroot if you can enter into TTY … however, since you didnt post what the exact issue is you have its hard to tell… cant you boot into manjaro at all, or do you get stuck on black screen, or do you see some messages, when booting?
Oh, sorry. The system refused to boot after an update, it said something like your driver will not work with the new kernel or so. It been a year in the past.
so if i understand it correctly, you have this for a year… try booting into your installatian, and on the stuck screen can you enter into TTY by pressing Ctrl+Alt+F2 ? if so then try updating your system (yesterday was released a system update, so it will take some time): sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
so did you rebooted after the update?
so again enter TTY, and try uninstalling your nvidia drivers-dont install them again: sudo mhwd -r pci video-nvidia
then try updating your grub and recreate initframs: sudo update-grub sudo mkinitcpio -P
then reboot: systemctl reboot
if you still get black screen enter TTY, and run this command: startx
did it boot directly into your system or you had to use the startx command? if you had to use the command, than you still have issues, if you booted directly, then try again installing your nvidia drivers, go to system settings/hardware configuration/auto install proprietary driver, then reboot and check if you can boot normally
