    This is good but I have two large questions. You have a RAID0 and you mentioned that you added a new SATA SSD just for Linux. You are apparently finding only one large 932 GiB drive sda which has Windows and 30 GiB sdb which looks to be your USB drive.

    Q1: What has happened to the new SATA SSD you installed ?

    Q2: Is F27 somehow detecting the RAID0 NVMe array transparently as a single drive as it would with true hardware RAID ? With fakeRAID both NVMe drives would be seen as sda and sdb and you would access the array with a /dev/mapper entry. Or is F27 detecting only one of the drives ?

    To test this you could try reading from sda from the live USB by mounting sda as read only. If you can read directories and files then it must be accessing both drives in the striped array as reading from only one drive of a striped array would have only half the information.

    Re: Fedora 26, FakeRAID, unrecognised m.2 SSD

    ok i will try to explain more clearly.

    My setup was:

    -raid0 (windows)
    --m.2 1 250GB
    --m.2-2 250GB

    -Sata SSD 1TB (Documents)

    all drives run thru Intel RST, so they were not recognised at all. except my usb live disk.
    in Fedora 27, my SATA SSD 1TB appeared, so I added another m.2 drive to install Fedora 27. so now my setup is:

    -raid0 (windows)
    --m.2 1 250GB
    --m.2-2 250GB

    --m.2 250GB (fedora 27)

    -Sata SSD 1TB (Documents)

    so answer to question2 is sadly, i'm still unable to see raid0, but it's now detecting other drives in my system.
    also, to boot linux I have choose F11 in bios to enter boot options as there is no way to install grub in raid0. It bit a hassle but it's fine.

    Re: Fedora 26, FakeRAID, unrecognised m.2 SSD

    Can you try an FC25 instead of FC27 ? I just had a problem with the Disk Config in FC27, so I reverted to installing FC25, and then upgrading with "fedup".

    Also, could you try setting your BIOS into "Legacy boot" mode ? ...just a thought. It helped me long ago when trying to install on a laptop over a hardware raid 1.

    If you had read the whole thread including the last post the OP has now successfully installed F27 on a new M.2 NVMe SSD. It didn't work at all with F26. Also fedup is obsolete and has not been used since F21. The new method is dnf system upgrade. Therefore you couldn't upgrade from F25 using fedup as it is no longer used.

    https://fedoraproject.org/wiki/DNF_system_upgrade

    By the way what are FC25 and FC27 ? Fedora Core ? It has been just Fedora since Fedora 7 released in May 2007. Therefore your terminology is over 10 years out of date.

    Also, could you try setting your BIOS into "Legacy boot" mode ? ...just a thought. It helped me long ago when trying to install on a laptop over a hardware raid 1.
    This won't work for the OP as they would have to re-install Windows into Legacy CSM mode which may not be possible.

    Also fakeRAID is not real hardware RAID.

    Re: Fedora 26, FakeRAID, unrecognised m.2 SSD

    i can confirm legacy bios mode haven´t solved any issues.
    anyway can´t manage to find my m.2 raid0 windows installation and it´s no big deal. Just sadly can´t have a grub OS selector when the system loads up so have to make it manually with F11.
    as I understand it should be written in the raid0 partition?

    I thought will make Fedora boot 1st but, this doesn´t work either as raid0 doesn´t show up as I mentioned before.
    Anyway this works fine for now, but probably if i´ll get in love with linux should loose the raid.

    The terminology reflects the current naming conventions for Fedora release's.

    Except for the lowercase fc in the kernel line uppercase FC does not appear in the OS name. The fc in the kernel name is used for historical reasons for continuity. It was 'fc' for Fedora Core 1-6 and 'f' by itself would be too short so for continuity fc was kept. However it has been Fedora since version 7. Virtually no one calls the OS itself FC. People use the shortcuts F25, F26, F27. You see it all the time in this forum.

    https://fedoraproject.org/wiki/FAQ#W...ora_Core.3F.27

    What happened to 'Fedora Core?'

    Fedora Project originally had two repositories, Fedora Core and Fedora Extras. Packages in Fedora Core repository was maintained by Red Hat developers and was part of official Fedora media and Fedora Extras was a add-on online repository open to volunteers. As the community around Fedora project grew, technical advantages (packaging guidelines, package review process in Fedora Extras) and limitations (packages in Fedora Core cannot depend on Fedora Extras but only vice versa, Fedora Extras packages were not included in official media) and other non technical advantages (Red Hat developers and community volunteers can work together in a team, no perception of any repository being treated as second class etc) led to a merge of Fedora Core and Fedora Extras into a single repository just before the release of Fedora 7. Since the repositories have merged, Fedora Core is no more. The releases are simply called Fedora.

    Why does the tag in my packages say "fc"?

    "fc" used to denote "Fedora Core. However after the Fedora 7 release, it has been retroactively renamed to "Fedora Collection" along the lines of GCC which is now "GNU Compiler Collection". From the perspective of version comparisons in RPM, it was easier to adopt a new meaning for c rather than dropping it simply because it refers to the old Core appellation.
    Therefore the OS is now named Fedora but fc remains in the package tags for continuity. Most people would contract Fedora 27 to F27.
