ubuntu doesn’t work :UUID=xxxx does not exitst

My computer has two systems, Windows 10 and ubuntu18.04. Today, when I tried to get into Ubuntu(I already laid it aside for about one week ), the whole screen showed pure purple for at least 10 minutes, so I forced the computer to shut down.Then when I tried to get into Ubuntu again, it showed :

Then I tried to open ubuntu in recovery mode,but the outcome was same.And I also tried this solution:https://forums.linuxmint.com/viewtopic.php?t=47594,doesn’t work either.
At last I run fsck.ext4 -y /dev/sda1(where the root is),and showed:

How to partition hard drive in Ubuntu 20.04

I’m literally brand-new to Linux and Ubuntu, so please forgive my ignorance and bear with me here. I purchased a Dell Inspiron 5593 recently and immediately installed Ubuntu 20.04 on it. Long story short, the keyboard is screwed up, and the place I bought it from won’t service Linux OS. Gotta be Windows/Mac OSX for some stupid reason.

So now I’m trying to partition the hard drive and reinstall Windows on the the partition. I’ve checked out GParted, but I haven’t been able to follow the documentation. For example, I don’t see any unallocated space on my disk, and I’m not willing to unmount my main disk without knowing what that will do to my computer.

Honestly at this point I’m ripping my hair out and would just appreciate some clear instructions on how to partition a hard drive in Ubuntu 20.04 because I’m clearly too technically illiterate to understand GParted’s documentation.
