I have quite old PC (Award BIOS v6.00, 4GB RAM Core 2 Duo) and Netrunner 18 installed on it. Recently i've tried to configure my LAMP server and broke up a little because i've tried to add myself into a "www-data" group, but accidentally i forgot about -a flag, so i removed myself form all other groups (sudo, adm etc.). Now, after reboot, i can't do anything with sudo privileges.
I found solution here: How do I add myself back as a sudo user? but next problem appeard: When i hold Shift key, "GRUB loading." text appears, and still can't see GRUB menu. Next thing i can see is standar Netrunner menu and system booting normally. Theres no errors and nothing. All i have acces to is GRUB command line (by pressing C key) but i don't have "mount" command. I add that i'm quite newbie in linux :)
My question is: can i do something more than just install OS all over again?
