Question Laptop Dell Latitude memory partition screwed.

[Galeran]

First i wanted to install Linux Mint but i completely deleted the Windows partition cause at the time i thought i wouldn't need that.
Now i wanted to try and do a dual boot, problem is i couldn't create a valid partition for Windows and i ended up messing up the whole thing.
I tried to reinstall Mint but in the process of creating the partitions it crashes and now all that is left is my poor dead laptop.

I though about trying to connect an external hard disk through USB port and try to run one OS there to try get access to the internal SSD and try to fix it from there.
Any tip is welcome please help me bring him back to life.
