New Desktop Computer and SSD Drive

[colin]

I very recently bought a new desktop computer which came with a 500GB SSD drive and a mate of mine installed Ubuntu GNOME 17.10 on it (which i'm not very happy with). But only a couple of days ago i decided to run a "live" cd, Ubuntu MATE. My new desktop has an external CD/DVD drive and i selected this drive in order to run the "live" cd. After i had run the live cd i wanted to change the boot order in the bios back to what it was originally but there are two entries for the ssd drive and i just wonder if i have choosen the wrong one? The entries are:

a) ubuntu (PO: CT500MX500SSD1)
b) PO: CT500MX500SSD1

Would it make a difference if i choose either one?

Also, my mate installed the OS on the SSD drive.
But i would like to know if would it be possible to install an internal 1TB SATA hard drive
So that i could keep the SSD drive just for the OS + updates and everything else would
go on the internal sata hard drive. Hope i'm making sense here lol. 
 
Thanks all

Hi Colin,

Your post doesn't seem to be related to Linux Lite but I'm guessing the Ubuntu line would be the "correct" one.
Also, the second one could be related to another boot section, another OS or maybe the UEFI parition (if in UEFI).

Cheers!
