I can't boot Qube OS 4.3, I ruined grub configuration

After upgrading to Qube 4.3 with dual boot other linux system (I know the risks for dual booting with other system) trying to put both system in one list in grub when pc starts I fucked up and delete grub files in boot partition of both systems, I managed to fix the other system but I can’t get into Qube to regenerate grub configuration files, I install live usb of qube but after decrypting the partition qube is very complicated with LV0 something I can’t even mount the partition and get to chroot, so is there a tutorial or a way I can fix this without reinstall entire Qube OS.

Hi!
