This cannot really be happening Just a side thought but if the machine uses a M.2 type PCIe drive shipped originally with Windows on it then, because the swap is physically easy and quick, I might consider just buying a second M.2 for a LInux install thus keeping the original with Windows. - Mark

Apparently things haven't changed much. Thanks for the info; I'll know to select AHCI when I install. -- Walter Dnes I don't run "desktop environments"; I run useful applications

Back to the original question: I've not had a Dell with this option yet, but I understand Dell uses RAID with NVMe drives because it allows Intel RST drivers to work with most/all NVMe drives. I'm not sure if any of the Dell onboard software to restore the Win10 OS also depend on this. Once you initialize the OS I think you won't be able to run it in a different mode. http://forum.notebookreview.com/threads/why-does-dell-set-the-bios-to-raid-always.832016/ However, I've seen it mentioned in various places Linux will not be able to see the drive if RAID is selected - I don't know if this is still the case. https://www.dell.com/community/XPS/Pros-Cons-AHCI-vs-Raid-On-XPS13-9300-NVMe/ td-p/7636984 signature.asc Description: This is a digitally signed message part.

And Windows Home has not > forced an update all that time. The drive may be 1TB, but the data on it must be significantly less. Clonezilla can copy and compress the data into a backup image for later restoration, should a claim against warranty arise. Whether a MSWindows Update took place or not, or indeed whether the OS was even initialised or not (first run), is pretty much immaterial, as long as the failure is related to hardware and data can be provided to this effect. I've returned a PC because smartmontools showed an imminent disk failure and another because it failed an overnight run of memtest86+. signature.asc Description: This is a digitally signed message part.

Answering on my phone. No experience with Dell machines in years but I imagine setting RAID in bios assumes you want to use a built in hardware RAID controller which may require a specific driver vs the standard AHCI interface. Check your manual carefully. HTH, Mark >
