[Solved] Can I run this off my HD?

[Creighton Miller]

There is a icon on the desktop 'install Linux Lite' or so. Double click it and just go through the installation process. Since it's the standard Ubuntu installer you should find many video on Youtube for instructions.

This will expose me as a luser but I'm having trouble being certain that I am pointing the installer at the drive I'm intending. I'm running LinuxLite off a USB and I'm trying to install on an SSD that's in the machine. Would you have any advice for me? Once I suspect that i did an install right over the top of my USB and had to recreate it.

I'm seeing notifications that tell me that there are mounted partitions on/dev/sda (and I don't know what that means, I did mount the drive icon on the desktop during troubleshooting)

When I'm in the "installation type" screen I'm not sure whether the statement that LinuxLite is on the computer means that it's on the ssd or on the usb, and I don't know whether "erase disk and install" refers to the ssd or the usb.

If I choose "Something Else" I don't understand what the "devices" are referring to and in the dropbox at the bottom I finally can see my SSD but I'm not sure if "Device for boot loader installation" means that the "device" is coming to or going from the "device".

I think I'm just one brain fart away from understanding this. Does anything stick out to you?
