    Dell Inspiron 7490 and Intel RST - a variation on the usual complaint

    So, can't switch to AHCI as so many of us have sadly discovered. This means the computer will not accept Ubuntu or other mainstream distro)
    And yet, i can install and run Endless OS (but i don't like it much)

    So, is there any hope of applying Endless's install magic to mainstream distros?

    Re: Dell Inspiron 7490 and Intel RST - a variation on the usual complaint

    Can you do a full install to an external drive?
    I for years did full installs to any flash drive larger than 16GB. Install was very slow, but with some changes to reduce writes, they have worked.
    I do not use them for daily use, and they do have limited life.

    But then I installed to a SSD in an external USB3 adapter.
    I upgraded my desktop with newer NVMe drive & removed the smaller M.2 SSD. So to use SSD I purchaced a inexpensive M.2 to USB adapter. It is almost as fast as it was as when an internal drive and lot faster then my internal HDD.
    I am just about to the point of not buying any more USB flash drives (I have a lot) and only buy SSDs.

    You should still be able to run Ubuntu in a virtual machine. I do not have the AHCI problem, but this works for me.

    Thank you for your reply. I have read that article. The problem is that the Inspiron 7490 has no way to switch to AHCI, and so the C: drive is not seen by the Ubuntu install. It's a known problem that only Endless OS has seemed to be able to overcome. Again, thanks for taking the time.

    Thanks for responding. I'll have to give that a try.

    Thank you oldfred for your reply. The machine in question is a laptop, usually used away from a power source or even a table, so an external SSD has limited appeal in this case.
    It's been a while or two since i tried making a persistent Ubuntu USB. I never really had much luck with that. I'll try again in the hopes that the available tools have improved (or that i have!).
    Thanks again
