So I think part of my problem is that after installing I still had ~17 GB of space left on the SSD and accidentally filled it with downloads, I wasn't able to download directly to my SD card or external HD and when I moved them in the file explorer I trashed then from the SSD but didn't empty the trash.
The Zorin download page says
Zorin OS Lite needs at least
| CPU | 700 MHz Single Core – Intel/AMD 64-bit or 32-bit processor |
|---|---|
| RAM | 512 MB |
| Storage | 8 GB |
| Display | 640 × 480 resolution |
So I don't know why it should need 60 GB as @StarTreker said.
Is there a way to reformat my drive to delete all the data and reinstall Zorin lite or should I just give up and try to download another copy of windows 10 to reinstall (these netbooks don't come with disk drives so no reinstall disk) ?
