Windows 7: BIOS not ACPI compliant during installation, Windows 7, Asus X751MA

As far as I know, the installation of Windows 7 32 bits is unfaisable in UEFI, you have to enable CSM. This is the OS I use on the PC i'm using right now.

I'm using a Windows 7 Ultimate with Service Pack 1 (x64) ISO unlocked downloaded from a torrent site, since I couldn't get it somewhere else (sad to admit but it's true). I was using another Windows 7 Professional (x64) official DVD but after a few installs, I decided to get another ISO because it was annoying to every time download the SP1 after a fresh install.

The Hash key from the ISO is 9F92877E1AB55BED390040762914123A14868CF6. I used ei.cfg Removal Utility to relock the ISO and checked the Hash key again. It changes to 5370BB44F497E1B19114C7CF70F5CDEF9F3A2582 which is the correct SHA1 key.

I used this ISO on another computer (not in UEFI) and everything was fine.

I made a bootable USB with this ISO thanks to Rufus, and the result is the same.
  • CSM disabled/#1 Boot on UEFI USB/Fast boot Disabled/AHCI -> Screen frozen
  • CSM disabled/#1 Boot on UEFI USB/Fast Boot Disabled/IDE-> Screen frozen
  • CSM disabled/#1 Boot on UEFI USB/Fast boot enabled/AHCI -> Screen frozen
  • CSM disabled/#1 Boot on UEFI USB/Fast Boot enabled/IDE-> Screen frozen
The frozen screen occurs at the same time with the same red artifact (see picture in previous post) only in UEFI mode.

The Blue Screen is the same everytime (each digit is identical) and occurs only in CSM enabled.

The BIOS in this system is not fully ACPI compliant.
Please contact your system vendor for an update BIOS. STOP 0x000000A5
(0x0000000000000011, 0x0000000000000008, 0xFFFFFFFFFFD1B018,
0x0000000020120913).

Of course I contacted Asus before posting here.

I'm experiencing troubles when I attempt to install Windows 7 64 bits on my new
laptop X751MA. In BIOS, I've disabled Secure Boot and Enabled CSM to be allowed
to boot on the Windows 7 DVD. I can see the progress bar "Windows is loading
files...", then the Starting Windows screen during 5 seconds and after that there is
the following blue screen: "The BIOS in this system is not fully ACPI compliant.

several Asus laptops without problems, it's the first time i see this one.
The first response I had is:

Thank you for sending us your question.

I''m sorry to hear you are not able to install Windows 7.

Unfortunately we can''t provide you any support with downgrading your notebook to
Windows 7, that is because we only support the original product configuration.

The reason for this is because we diddn''t test Windows 7 on your notebook so we
can''t guarantee it works well.

During the install of a different operating system you will face problems most of the
time, in this case you allready experienced some issues during the install and we
recommend to keep your notebook as it is.

I hope I informed you enough.

Well, I can understand you can''t provide support for your product for each different
OS out there, but I''m very surprised that Asus completely give up support for
Windows 7 because it still the most used OS around the world (even today Windows
XP is more used than Windows 8.1).

Can''t you provide a BIOS update to allow me to install Windows 7 ? You have already
done that for the X551MA and his specs are very similar to the X751MA.
Asus support replied:

I recommend to keep the BIOS as it is now.

Maybe you can try the following steps to enable the Windows 7 Installation:

1. Turn your system off.
2. Press F2 during bootup to enter the BIOS.
3. Go to Security and set Secure Boot on Disable.
4. Go to Boot and set Laucnh CSM on Enable.
5. Press F10 and save your settings and restart your system.

Did this had any effect?
I replied:

Yes, I did every single point, as I said in my first message.

I can boot on the Windows 7 DVD, I see the progress bar "windows is loading files..." after that I have the "Starting Windows" animated logo and 5 seconds later, a Blue Screen Appears.

The BIOS in this system is not fully ACPI compliant.

0x0000000020120913)

Usually, when i reach the langage selection menu, I press MAJ+F10 to start the command prompt, I delete all partitions and I convert the disk into MBR.

After that, i do the installation of Windows 7 on a new partition.

I did it on 3 Asus notebook without problems (F751L, K72J, X75V).

The X751MA has the minimum specifications to run Windows 7, so I don''t know why it''s impossible to install it ?

I presume it''s a BIOS parameter that is missing. The X551MA had exactly the same problem and a BIOS update fixed it.
Now i'm waiting for the next response.

With all respect to you, i won't blame Asus for this. They designed this laptop specifically to run "Win8.1" and nothing else. On the official product specification page ( Notebooks & Ultrabooks | X751MA | ASUS Global ), only Windows 8 is listed as the supported OS.
Well, if you want to know all the story, this laptop is for my dad. He came to me with the printed product description of the computer and I said it was ok for office work. But like me, he is allergic to the new Windows 8 that is not designed for "professionnal" use. Furthermore, he has some softwares that doesn't work with Windows 8 and he doesn't want to buy the last version of them because these old versions have all the functionnalities he needs.

Of course, I know that Asus laptops have now Windows 8.1 pre-installed systematically. But on the product page of the store it isn't specify anywhere that it will be IMPOSSIBLE to install another OS. And I'm not trying to install Linux, I'm trying to install Windows 7, the first used OS in the world today.

In addition, I've already downgraded from Windows 8 to Windows 7 on several Asus laptops, this is why I didn't investigate in depth.

I notice that Windows Boot Manager is listed in BIOS Boot Priority and Override options, while the hard drive itself does not appear. This could be a problem if you're trying a Legacy install with CSM enabled. It would only utilize WBM for a UEFI install, but need the hard drive present to prioritize to install to CSM. So it's a long shot but see to it that the hard drive is in the Boot Order when you try installing with CSM enabled, otherwise follow the prompts (hopefully) to the right hand side of BIOS to add a Boot Option so that the hard drive is in the list - and set first to boot if trying a flash stick install which should always be triggered from BIOS Boot menu key.

Note that the UEFI formatted flash stick for GPT option when formatted by Rufus will not work for the Legacy CSM install. Use Windows 7 USB-DVD Download Tool or if it is fussy about the ISO use UltraISO Software To Create Bootable USB Flash Drive.

Hey greg,

I tried to add the HDD in the boot list with Add new boot option.

Unfortunaltly, the Blue Screen appears again, same with the new USB boot.

I think I've performed every possible configuration in BIOS to install Windows 7 on this computer. I can now have the conviction this is the BIOS that can't manage the ACPI for Windows 7, it's only designed for Windows 8 and Windows 8.1.

I'm going to wait the Asus reply and see if I can obtain a BIOS fix in a reasonnable delay. If it's not the case, I will return this laptop to the store, even if they don't accept exchanges or refund. It must be indicated in the product description that you will not be able to install another OS. This is not acceptable.

I notice that you have non-UEFI DVD option in the Boot order, followed by HD. Confirm you have booted that DVD choice since it does have the hard drive there to utilize if it will install with CSM in Legacy mode.

I'd keep the pressure on Asus for a BIOS update and also keep a current and very thorough Google search for that model Asus and BIOS' to find what others are doing about it.

Meanwhile you can install Windows 10 Technical Preview which is still pre-beta but quite stable and a worthy successor one day to Win7 with the Windows 8 style apps minimized to a corner of the Start Menu. I suggest this because it's free and getting involved in their Insider program to provide feedback will likely earn you free copies as it did for us in Win7 beta.

Yes, I confirm you I choosed the DVD in NON UEFI.

I searched every site, forum on the X751MA, essentially russian. They come to the same conclusion: the BIOS does not manage the ACPI for Windows 7.

(I hope you are ready for some state-of-the-art traduction)

Another possible long shot: have you tried running Setup as Admin from the Win7 installer Sources folder using Windows 8 on there?

Hi

There seems to be a recent BIOS update dated 2015/04/29. It may or may not add the OS selection option in BIOS but definitly worth a try -

Did you manage to downgrade?

Hi! were you able to downgrade? we bought this "old" notebook on a garage sale (go figure) and I was about to try to downgrade it to Win 7. Yup I know this is odd but we're doing it for sake of familiarity with the person who will be using it.

I'm doing my due diligence to find out if it is at all possible before I even move anything on the notebook itself. After having read the thread, I'm very reluctant to embark on this chore.

I would appreciate any updates on the issue.

Thank you!
