Install Ubuntu only (no dual boot) SSD+HDD

in flag

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

enter image description here

and when booting there are serveral options:

  1. Ubuntu
  2. Ubuntu 20.04.2 LTS

enter image description here

does that mean I installed 2 OS?

Yes, you did install it twice. Details to know: The location of the ESP isn't relevant. You can keep it in the HDD provided that drive has the first priority in UEFI BBS boot order but then you MUST use something else and define at least / (root), the only partition needed, on the other drive. Probably better to use GParted in a live session and delete everything. Then change the boot priority to the SSD and then proceed with a fresh installation.

You should install it on the SSD and use the HDD only to save stuff. The SSD is much faster therefore better for the OS and programs whereas the HDD is cheaper to save big files (e.g. videos) for which the drive's speed is much less important or not at all. And having only one OS installed is what obviously makes sense. So, again, in a live session you can delete everything a start over making sure to select the SSD this time.

You should post duplicates. "LIve Session" is what you have when you boot the installation media and select "Try Ubuntu"

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
