Question Cannot access singleton drive (in RAID mode) when booting from USB

[kayton]

I bought a brand-new Dell desktop that came pre-installed with Windows 11 It came with a single onboard nVMe M.2 drive set up in the pre-installed RAID mode. I added an external SATA hard drive that was removed from a different system that did not use RAID. Windows 11 boots and sees both drives. However, if I boot from a Windows 11 USB installation drive, neither the installer nor DISKPART can see the SSD nor the hard drive. DISKPART reports that the flash drive is the only drive in the system. How do I see these drives when booting from a USB flash drive? There are some folders on the M.2 drive that have issues with permissions, so I was hoping to boot to the USB to remove those pesky folders. Thank you.

This may help if you don't want raid...

Drives need to be i initialised and formatted to use in raid configuration. Maybe the usb drive has not been initialised and formatted??

Thanks, but using RAID allows much faster disk access.

The drives are all initialized and formatted. It appears that drivers need to be loaded. But I don't see how to load the drivers while booting from a Windows installation flash drive.
