Failed to start default target ERROR (after moving home to another drive)

[AutisticChiliDog]

I was following this guy's tutorial on how to move my home folder to another drive to have space and I rebooted and then the errors came.

I'm not sure if you guys can see the images but I'll try to describe it best as I can.
So I turn on my pc as usual, go to linux mint option click on it, but it says I'm in emergency mode and when I press Control+D I get an error saying "systemd-fstab-generator[834] Failed to create unit file /run/systemd/generator/home.mount as it already exists"

It prints this 4 times then it says "Starting default target"
Then "Failed to start default target: Transaction for graphical.target/start is destructive (emergency.target has 'job' queue)"

Then if I wait a few minutes, it goes to the login screen, but if I login its just a black screen then it goes back to the login screen.

My question is, how do I reinstall Linux mint XFE, I also deleted my windows operating system im pretty sure because I wanted to make the jump to linux permanently.

I would really appreciate the help!

Boot the live system, open there from the menu Timeshift and point to the partition with the snapshots. Now revert to a suitable snapshot.

How do I open the Timeshift menu and point to a partition with a snapshot? I should also mention that I can't get to the OS and when I try, I get the errors. My only options are using a command line

The first part of my advice is: Boot the live system.

There is a menu like in the installed system, you find Timeshift there and after opening it you set the partition.

I dont even know what boot the live system means, if thats the first choice at like BIOS then I've done that. I'm gonna do all 3 options and send back everything that happens, also sorry for not using imgur, they don't upload fast enough and im being gangstalked as well.

https://ibb.co/YXh98dw CLICKED ON 1ST OPTION, LOADING
https://ibb.co/fFf5bv7 GET THIS MESSAGE
https://ibb.co/YcjKnKk GET THE STARTUP AT TARGET ERROR
Wait a few minutes, screen turns black then go to login screen.
https://ibb.co/bv8B8d8
If I login, screen goes black for a few minutes, I can move my mouse. Then goes back to login screen.

Now going to option 2:
Generic mode

Option 2: choice 1
Loading screen
Then the same screen as before
https://ibb.co/Y3Mtnhc
I press control + D and the error shows up
https://ibb.co/8D9x89j
Waiting and nothing seems to happen, I suppose when its red that means I gotta restart.

Option 2: Choice 2:
Recovery mode

Everything seems to be going well until it says MTD device must be supplied

Then another message
https://ibb.co/StGZtxX
Then I get to the Recovery Menu (filesystem state: read-only)

I knew I said I was gonna do all 3 but everyone knows what UEFI Firmware probably looks like.

So just if anyone knows how to fix this, please let me know

The live system is that, what you used to install Mint. A DVD or an USB stick.
