grub corrupted after update

[soundlord]

I already did but was stucked... because grub2-mkconfig failed.

rescue system is booting

got hd2,msdos1 as the set root grub directive took pictures of the screen the computer is far away from this one

[soundlord]

my messenger name is "hurukan imperial stepper" it may be better

[soundlord]

map of partitions is:

hd2 /dev/sdc
hd3 /dev/sdd
hd0 /dev/sdb
hd1 /dev/sda

I have rarely such issue so I'm not efficient at all to troubleshoot.

my fstab shows

/dev/sda6 as /

fdsik -l shows asterisks at "strangely"

/dev/sda1 EFI (100 Mo) but the /boot/efi is empty
/dev/sdc2 Linux

I will try to lead you through it.[/QUOTE]
What's the output from:

grep LOADER_TYPE /etc/sysconfig

Obviously, you need to change the path depending on where you mounted the root partition.

And are you using "btrfs" for the root file system?

[soundlord]

thank you very much for your "psychic support" ^^
I was near the nervous break down ^^

What I did:

Boot with 15.1 usb stick
selected rescue system

mount /dev/sd** (where the system was) /system | mkdir /system
mount --bind /dev /system/dev
mount --bind /proc /system/proc
mount --bind /sys /system/sys

chroot /system
grub2-mkconfig -o grub.cfg

yast -> bootloader -> write generic to mbr
exit
reboot

...and I can now send my covid19 charts before midnite ^^

Those steps are about right. If you are using "btrfs" then you also need a "mount -a" before the "chroot", though it might work without.

I think you are saying that your system is now up and running again.

[soundlord]

I confirm ^^
Thank you, I'm suggest to high stress when I can't sleep at night with those temps... thank you very much !!
