Some time ago I made my own „OS” based on mint(Debian Based distro). About u week ago I deleted 3rd partition with Ubuntu. Before this weekend I got BSOD on windows, so I'm stuck on mint. And here is my problem with third OS: i deleted accidentally grub. The problem is yet bigger because filesystem was btrfs. I copied all files (even system)to external drive and formatted partition with mint to ext4, then I recopied system and tried with GRUBrepair. As I saw root and sudo was locked (mint doesn’t have su by default), so I tried to repair by myself. Now system is stuck between: grub shell, busybox shell (initramfs error), live boot mint and „shell”with prompt for root password (i didnt setted up that YET). Is there a way to boot PC normally? Or i’m stuck on live-boot? I don’t have space for installing third OS (space which stayed after deleting ubuntu was joined to windows) and my PC is yet on guarantee... (yet worse but guarantee is only for physical things, OOF)🙄
PS: bios on my pc is „aptio setup utility”, there is no way to disable uefi and i can’t: boot rescueCD from pendrive and/or boot pc from external HDD. I don’t have external CD/DVD reader.
Thanks for answer (if any)
When I tried
reiserfsck --check /dev/sda6 I got some error :
