Downgrading Pre-installed Windows 11

[FriendlyGabe]

I recently got this computer (HP Victus 15L) to use with my 3D printer, but the software for my 3D printer is only compatible with windows 10. This computer came with windows 11 pre-installed. I have tried to use Microsoft's Windows 10 ISO tool, and I am able to get into setup and progress to the select disk screen, but no drives appear. Using /diskpart /list disk no drives appear except for the media drive itself. HP doesn't have any Intel RST driver support for windows 10 on this device according to HP Support documents. I have also downloaded HP's Cloud recovery tool, but I have no option of creating a windows 10 image. HP support told me to contact Microsoft, but I fail to see how that would help.

I cannot use this computer unless I can install windows 10, any help would be appreciated.

See if this works for you...

I have zipped up and attached below, the Intel storage controller drivers that I hope work for Windows to find the hard drive.

Copy all of the files inside both of the folders inside the driver folder to a USB flash drive.

Have the flash drive and your W10 installation media plugged into USB ports.

Boot from the W10 installation flash drive.

When you get to the screen where no drives can be found, click on the Load driver option, browse to the flash drive with the storage controller drivers on it.

If you check the box, it will only include the compatible driver.

Click Next and if those are the right drivers W10 should find the drive and install.

Thank you! Worked perfectly and system is functioning as intended.
