Dell Precision 7730 OEM Ubuntu

I'm struggling with installing Ubuntu. The only way I could run Ubuntu was with nomodeset but nothing worked graphically.

Before that I had made a very successful install with RAID config on, but due to a lot of crap I needed to install both Windows 10 and Ubuntu. I turned off RAID (also better in Windows 10) and the Ubuntu installer wasn't even loading. I had a lot of problems, and I couldn't start an installation without using nomodeset.

I had the same USB stick. When it succeeded it was on mbr in Rufus, (with Ubuntu 18.04), but Ubuntu 20.04 didn't seem to work. Is there a way I can obtain the OEM image? I called Dell before, but they refused to help.

You crapped out with the Dell OEM image request, but you mentioned that you successfully installed Ubuntu 18.04 with Rufus. You will need to install Windows 10 before installing Ubuntu and then select UEFI mode in Rufus in order to be compatible with Windows 10. Getting the Ubuntu installer to work in UEFI mode on your Dell Precision 7730 is your biggest problem as I see it. Installing Ubuntu 18.04 worked before, so try installing Ubuntu 18.04 again and immediately upgrading it to Ubuntu 20.04.

I sit in a Tesla and translated this thread with Ai:

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.
