I've tried to reinstall several times and didn't find any good results. this is my first time installing ubuntu in my PC.
I have SSD (240gb) and HDD(1tb). i want to install ubuntu on SSD for better performance.
I just want to make sure is I did the right installation?
cmd : sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
and when booting there are serveral options:
- Ubuntu
- Ubuntu 20.04.2 LTS
does that mean I installed 2 OS?
