today i used
sudo pacman -Syuto update my system, but something went wrong: my laptop battery was not enough to finish this job. So it just turned off, at the next time power-on, it just shows GRUB interface(shows kernel not loaded, and something is missing).
I tried to fix it by searching google/manjaro forum, but still can't find where's the problem.
1.get the message like this
error: file '/boot/vmlinuz-4.19-x86_64' not found. error: you need to load the kernel first.
2.try other's solution:
Using livecd v17.0.1 (and above) as grub to boot OS with broken bootloader
3.still cant fix it(now system is up-to-date), after use
update-grub it shows
Generating grub configuration file ... grub-probe: error: cannot find a GRUB drive for /dev/sdc1. Check your device.map. grub-probe: error: cannot find a GRUB drive for /dev/sdc1. Check your device.map. done
sda=broken system and sdc=live-cd, don't know why it choosed sdc(that's the problem?)
(Now I start up this laptop, it direct display GRUB promot)
What should i do next?
(BTW, if there's a way to backup all configs and maybe restore it after install manjaro again?(But don't want this option, fix it maybe better for this newbie XD))
