I recently bought a Dell Precision 7530 laptop which came preinstalled with Ubuntu 16.04 on a 500GB SATA drive. Later I bought a 1TB PCIe SSD and installed it in a free slot in addition to the original SATA drive. I then installed Ubuntu 19.10 on the new SSD drive. The following is a screen shot from the Ubuntu USB installer:

The above screen shot shows that both disks were recognized at install time, and I installed Ubuntu 19.10 on the top most item from the above list: /dev/nvme0n1 - 1.0 TB SSD.

However, after installation completed and the machine restarted, there was no boot menu shown and it booted directly into the Ubuntu 16.04 on the SATA drive.

I then restarted the machine, and pressed F12 to enter the BIOS menu:

In the above screen shot, both the two items under the UEFI BOOT heading:

  • ubuntu, and
  • UEFI ST500LM021-1KJ152, Partition 2

refers to the preinstalled 500 GB SATA drive. Further if I enter BIOS setup, and then Boot Sequence, I get the following screen shot:

Also, I include a screen shot of the "Sata Operation" section from the BIOS setup: enter image description here

Any suggestions what I should try here?

    Many with Dell need UEFI update & SSD firmware update, even if SSD is new. It looks like you already have AHCI on drives. – oldfred Oct 29 '19 at 15:56
  • Not sure if it applies to your machine as well, but setting up dual boot windows on my Dell XPS was a major pain. Your symptoms seems similar to what I experienced so I would suggest checking this article for BIOS settings and other tips. – Smurfz87 Oct 29 '19 at 14:37
  • You need to enable RAID on in the BIOS – George Oct 02 '22 at 05:26
