iN THE MEAN time i got here https://linuxconfig.org/introduction-to ... epair-grub
because of this remarks about Boot-Repair:
"This app is kind of a gamble. It used to work perfect with legacy BIOS setups, but now having some trouble with UEFI and multi-boot setups. It will either work flawlessly for you or it will funk your GRUB up. Before using this you must be using Timeshift or other backup tools regularly, and you'd better get yourself familiar with some commands"
https://community.linuxmint.com/softwar ... oot-repair

it gave me this

Code: Select all

grub rescue> ls (hd0,1)/
lost+found/ swapfile/ media/ bin/ boot/ dev/ home/  lib/
lib64/ mnt/ opt/ proc/ root/ run/ sbin/ 
srv/ sys/ tmp/ usr/ var/.........ETC

Code: Select all

grub rescue> set prefix=(hd0,1)/boot/grub
grub rescue> set root=(hd0,1)
grub rescue> insmod normal
grub rescue> normal
error: symbol 'grub_file_filters' not found
error: symbol 'grub_file_filters' not found
so we are stucked again :?

You can try the GRUB command line from a live USB.

Is grub really necessary? Is LM 19.2 the only OS on your computer? Can you pick sda in the bios boot menu and everything is good?

When you reach GRUB (not isolinux/syslinux) from the live USB, press "c" on your keyboard to enter the GRUB command line.

Now, try
grub> insmod ext2
grub> ls
grub> set root=(hdX,msdosY)
grub> configfile /boot/grub/grub.cfg

If that won't work, reboot to your live USB and open the GRUB command line (as detailed in the starting of this post)
grub> insmod ext2
grub> ls
grub> set root=(hdX,msdosY)
grub> linux /boot/vmlinuz(Press TAB key and select a working kernel, preferably the most recent one) ro root=/dev/sdY (any other kernel params here)
grub> initrd /boot/initrd...........(Same version as vmlinuz)
grub> boot

Off you go to your installed Linux Mint....

NOTE: (hdX,msdosY) and /dev/sdY refer to your installed Linux Mint's / partition.
