When I tried to install Android x86 on a partition on my production machine, and by mistake installed it using GPT on my MBR machine.
I pulled 2 all nighters to fix that.
That was when I learned about GPT and MBR.
Fml.

I have no idea what either is. Am i missing out? Feel like I should know what that is.

@PoliteRanter69 You don't need to know if:
- You don't use partitions
- You never cared for formats/wipes (they always worked for you)
- You are not force shutting down your PC too often
- You don't experiment with new OSes
- You don't care about how information are stored on your hard drive
- You don't care about how your PC boots
