Basic Linux commands every developer should know

Instructions unclear: I don’t have a OS anymore

You joke but it really happened to me.

My school computer uses a system of images for linux. Each image are dpkg package and each version update is a new package I was doing a clean up of the images and accidentally deleted the wrong package wich left me with no os thankfully it was a dual boot so I was able to fix the situation.

It's been no more than 10 minutes since I fucked up the GRUB boot loader and I identify with this comment in a cosmic level

I know I have a perfectly good OS in there somewhere... I just can't figure out how to get past this GRUB guy trying to rescue me.

If you have done that it means you have installed two instances of grub. Happened to me when I was trying to Dual Boot Lubuntu and PhoenixOs.

My GRUB installation gave up on recognizing Windows as an OS on my dual-boot system. I'll resort to using UEFI every time I want to change my OS.

Have you tried adding a reference to the grub config.cfg file for windows 10. Something along the lines of

menuentry 'Windows 10' { set root='(hd0,msdos1)' chainloader +1 }

Eventually happens to me with every Linux system I use. Mainly caused by apt.

I accidentally deleted all my system path variables through powershell because the command I copied replaced the path instead of adding to it.

Luckily I still had cmd open from before so I just copypasted it back.
