Windows – The BIOS in this system is not fully ACPI compliant

acpibiosbootwindows 7

I have a Dell Inspiron 3050 desktop (one of the little mini square PCs) which I'm trying to put some version of Windows on.

I'm able to load various Linux flavors, but when I try Windows, I get a blue screen with "The BIOS in this system is not fully ACPI compliant".

This happens on Windows 7, Server 2008R2, Vista, and XP, and happens both with a USB DVD drive and with a USB flash drive installation.

I'd be happy to upgrade the BIOS if I could – I have the exe from Dell's site for the latest, which I'm not even sure if it's different from mine, but since I can't get any Windows to load, I can't run it.

It won't run in Wine on Linux.

I can't boot to FreeDOS – I get "Remove disks or other media. Press any key to restart."

I've tried the "press F7 instead of F6 in the XP setup" solution – that gets me through the text-based installation but then blue-screens anyway.

The original recovery partition on this machine is toast – I lost that a long time ago, so I can't restore the emergency recovery OS.

My system is set for Legacy mode – whenever I try UEFI, I can't get a bootable USB drive to get recognized, regardless of whether I made it with unetbootin, Tuxboot, or Diskpart with manual copying. When I'm manually building the USB drives, I format them with FAT32 on MBR.

Is there some way I can boot to a command prompt or something with a Windows install disc, long enough to try to update the BIOS? Or any other way to get around this error message?

I'm not very good with boot stuff, so if you've got a complex answer, I'd really appreciate if you could dumb it down for me a bit.

I also encountered the same error when trying to install Windows 7.

This is what I have done:

  1. Go to BIOS. Opening it varies on every device. A simple search on the web will help you find how to go to BIOS.
  2. Under Advanced > OS Version, it was selected to Windows 10, which then I replaced it to Windows 7.

After saving BIOS configuration, I tried installing it again, and I never encountered the error, and the installation was done successfully.
