Installing Windows 7 on ASUS X551MA laptop (Bios not ACPI compliant error)

[I_know_nothing]

Hi,

I am trying to install windows 7 on a ASUS X551MA laptop that came with windows 8 64bit. I have swapped the original drive out with a 240GB SSD that is currently bare. I have a official windows 7 64bit upgrade dvd to install (I have always used this in the past) and an genuine windows 7 oem key.

Every time I boot from the dvd to start the install, windows says loading files, I get the windows starting (without the windows logo popping up) and then the message "the bios in this system are not fully ACPI compliant. Contact your vender for updated bios."

I have turned off safe boot and enabled CMS in the bios. Is there a step I have missed?

I have updated the bios of the motherboard to the most recent version to see if it helped. 5.13. The computer works fine with the windows 8 drive in it so I am pretty sure it isn't a bios corruption issue or a hardware failure.

Thanks!

Try the clean install method first to ensure Windows creates the correct partition type:

Possibly, you may need to enable legacy mode in the bios if that option is available or disable AHCI. Did you initialize the SSD prior to attempting to install? If not, you may need to initialize the drive first, then install using the clean method.

The easiest way to do this is to attach it to another system that's already running windows and initialize the drive in drive management. If that's not possible, you can probably do it using Partition magic:

Thanks for the detailed response, I never noticed but this motherboard actually has a BIOS setting for which operating system can be installed on it. I have never seen that before and don't know how I missed that before. I switched it to windows 7 and it is not installing correctly. Your answer could have been very applicable though so I will mark it as best answer. Thank you again.

Switching it to Windows 7 most likely disables AHCI and places it in legacy mode. You would then need to install using the clean method making sure to delete all existing partitions (Including the otherwise hidden MBR or GPT partition boot record which tells the system which way to boot) until there is only unallocated space left and then install to the unallocated space without creating a partition. Windows will create the necessary boot record and partition. If you create a new partition yourself, it's likely it might be the wrong type.
