HELP! I can't install Mojave on MBP late 2012.

I'm having trouble installing Mojave on my MBP late 2012, I have a Kingston SSD 240GB installed in it and I'm trying to do a clean installation with a USB drive.

I booted the Mojave USB drive and the first problem I faced was a Windows blue screen mid installation. I read that it was caused from an oldBootcamp installation and the EFI partition Windows left. I cleaned the SSD completely with Diskpart on a windows computer and tried again.

The second problem I had was the "MacOS could not be installed on your computer the target disk is too small". I found that this could be caused by the Mac OS Extended (Journaled) partition, so I formated the SSD into a APFS drive. The installation continued with no issues until the prohibitory symbol showed up. I searched for a solution I found out that I should select my SSD again on the boot option menu that appear pressing option key while the computer is booting. I did that and the installation continued to a point it failed again. So I reformated my SSD into a Mac OS Exteded partition and did the same thing, this time pressing control key when I select the boot drive. And it failed again with a prohibitory symbol, rebooted and showed the "MacOS could not be installed on your computer", this time saying " error -69854)".
