This is probably super simple, but I've spent about 7 hours over the last 2 days trying to get this accomplished. Most of the time is just waiting while things install or boot. I first tried putting the iso on a 64GB USB with the Pendrive USB installer and then installing from that. After many attempts where my computer would just freeze on a black screen or freeze during the language selection I found that many large USB 2.0 pen drives will not work. So I tried my smaller pen drive and actually got to the part where I pick the install location. It was confusing though because it had two different things, sorry but I cannot remember the names and it takes about 30 minutes to get to the screen. The top part showed all of the partions of all of my different drives, there are two interal SSDs and three external drives, but it listed them with a naming scheme that made it basically impossible to tell them apart. I think I found the right one though by the size of the partition and used space. The bottom had a selection box where it asked what drive to do something, which is what I don't understand. I thought I was just selecting the place to install. So I selected the same partition in both and tried to install but the button was grayed. So I tried to select the button where it says "create" something, thinking that I didn't have the partition set up properly but the create button is unresponsive.
Sorry for my crappy explanation, I can't remember the exact wording of the button/prompts. Is there someway I can install Ubuntu on the second SSD from the Windows environment? Thanks!
