Not able to set SATA operation to AHCI in BIOS (Inspiron 7490)

I am installing Ubuntu on my Inspiron 14 7000 and have run into the common problem of the installer not being able to find find any hard drive. The solution to this problem is here: https://www.dell.com/support/article/us/en/19/sln299303/loading-ubuntu-on-systems-using-pcie-m2-driv...

I need  set the SATA operation to AHCI in BIOS. In my BIOS I don't get an option for AHCI as seen below:

Does anyone have any ideas or suggestions regarding this? I don't need to keep the Windows installation so solutions that involve removing Windows are also welcome.

Re: Not able to set SATA operation to AHCI in BIOS (Inspiron 7490)

Someone else reported this because they wanted to install Linux as well.  I hadn't seen a system that only had Disabled and RAID as options, but I asked that person to see if choosing "Disabled" might simply disable Intel RST rather than disabling the entire interface.  That person never replied.  If you haven't already, try that and see if that allows your Linux installer to see your hard drive.  If it doesn't (because Disabled truly does disable the entire interface), then my only other thought would be that perhaps NVMe SSDs would behave differently.  The option wording specifically talks about the SATA controller, although that might not mean anything because Dell has used the "SATA Operation" wording for a while, and changing that setting on other systems definitely also affects NVMe SSDs.

If Disabled really does disable the entire interface and NVMe SSDs don't behave any differently, then it would appear that your system doesn't allow AHCI mode, in which case you would not be able to install Linux unless there's some Intel RST driver for Linux out there.

As for getting rid of Windows, you would just want to delete all existing partitions on the SSD before installing your new OS.  The OS installer should give you an option to do this at some point.

I'm also blocked by missed AHCI menu in BIOS to install linux on Inspiron 7490. Have you find a workaround/solution to do that ? Thanks!

Re: Not able to set SATA operation to AHCI in BIOS (Inspiron 7490)

I face the same problem too. It's rather sad as I liked Dell Inspiron 14 7490 a lot. I really need linux for my work so I spent the whole weekend searching for solution. I have tried switching the button to "Disabled" but it didn't work as linux on LiveUSB wasn't able to see the SSD. And I'm a bit afraid to format the whole SSD with Windows being deleted cause I'm not sure it will work.

It would be nice to get some comments from Dell support about the whole situation.

Re: Not able to set SATA operation to AHCI in BIOS (Inspiron 7490)

I find this whole situation outraging. Being able to use Linux is quite crucial to me, and apparently Dell doesn't give me any option to do so with this laptop. There's no reason why they would make it so hard to install Linux here (to the point of not proving an AHCI interface??)

Don't we have any other update/further information from them?

I might ask for a refund and never buy a Dell laptop again

I have the same issue. I can't get the Ubuntu installer to load linux because I can't set AHCI mode for the SATA drive.

I have the same problem. I also tried ubuntu daily image and fedora 31 until I saw this thread, thought it was just something about ubuntu 18. 

Any help will be appreciated. It would be nice some word from Dell.

Thanks

2 months that I have the same problem, please send a fix, because actually I want a refund and never buy a DELL again ! 

In 2020, you sell a computer not compatible with Ubuntu...
