It just baffled me as to why Dell set it this way by default.Ģ.

Exactly! I'm not, nor am i planning on ever, using a RAID configuration with this particular desktop.

Clean the SSD with diskpart to make sure there are no partitions.

What USB drive are you using and how did you make your installation media?.

The only exception I know if is when you install Windows 7 on a NVMe drive.

AHCI is preferred over RAID in all scenarios (the only time it would make sense would be if you were actually using RAID, but if you needed RAID, you wouldn't be using FakeRAID).

Now, I don't know if the changes to the BIOS/UEFI are causing a problem or whether im having a different issue entirely with the installation, but any help or insight would be wonderful. upon formatting the SSD, Windows 10 will not install the OS on the drive or allow me to delete the partitions I forgot only an hour ago. (Also decided to change the SATA operation from the default RAID to AHCI as i cannot understand why i would need to use a RAID configuration if I'm not setting up a RAID to begin with.)ģ. I had to disable secure boot, set the BIOS to use legacy boot to get the machine to even see my Win10 Pro usb boot key. Both drives mentioned are not the originally Hard drives that came with itĢ. To it simply, I'm reloading a fresh Dell XPS 8930 desktop machine so that i can use a Western Digital NAND 500GB SSD as my boot drive and then use a blank 2TB Seagate drive as pure storage.ġ. I'm back with another question that I'm losing handful of hair over.
