I'm trying to install Windows as a dual-boot on an Asus P8H67-V (Socket 1155) PC running Elementary OS (Debian).  Here's my configuration:

  • Intel Core I5-2500K
  • Samsung 840 Pro SSD
    • This previously had Windows 7 x64 installed.
    • I've cleaned it; now I'm trying to install Windows on it from scratch.
  • Samsung 850 Evo SSD
    • This is where I have Elementary OS installed.
  • Multiple WD Red (≥ 2 TB)
  • 2 × Zotac GeForce GTX 660
  • BIOS set to AHCI for boot
    • I consider switching back to IDE in BIOS not to be an option.

I'm trying to install Windows by booting from the following devices:

  • External DVD/BR Drive using a verified Win7_x64 Disc (this has worked on other machines)
  • Samsung USB Stick (128 GB, 8 GB Partition for Win10_x64)

I get this error message:

Load Driver

A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.

Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step

This message appeared for Windows 10 and Windows 7.

The installers boot like a charm, as does Elementary OS.

I have tried:

  • Using both a USB 3 port and a USB 2 port. No success over here.
  • Somehow I was able to boot both devices in IDE Mode – still it wouldn't let me install... Same message.

  • Assuming that it has something to do with AHCI instead of IDE in SATA Mode inside BIOS Configuration, I downloaded AHCI Drivers from Intel (chipset manufacturer) and ASUS (motherboard manufacturer) but none of them worked. The drivers were shown as applicable for the hardware (Windows 10 Setup), but I was still not able to continue the setup process.

Question:

  • Is there a possibility to determine which exact driver is missing? The error message is not what I would call conclusive as it does not really state more than "It's not working, I don't know why."

  • Is there something I missed? Any other drivers to try? Any preparation for the Samsung 840 needed I missed?

  • I've always had to set the BIOS to IDE mode, install the OS, install the AHCI drivers, and then switch the bios to AHCI. At least with Win7. I believe Win10 installed with AHCI support. Commented Jun 7, 2016 at 11:57
  • Disabling AHCI does not give me permission to boot from usb / external dvd drive. It also removes both SSDs from boot device lists.
