    Well i tried the P11-B2 bios on another new AXC 603G-Uw30 and i did get the Launch CSM option so i guess it should be the same. I am backing up win 8 and will install win 7 soon. Will let you know how it goes

    EDIT: No Problem win 7 installed on the P11-B2 BIOS. Life is good.

    If you're up for more experimenting, there have been several even newer BIOS releases recently, all apparently Win 7 compatible: B2L, B1L and B2. Version B2 is probably the most appropriate one to run with Win7 and 8.x.

    Click Download Drivers and Manuals | Acer Official Site then click the BIOS tab.

    Really, i just went to the site to check, i seen a P11-B0L but i did not see the others, i will check that new link you posted, but i don't thing i need the others at this time.

    EDIT: I see them i though they were older but there are the L version to support other OS. I wonder if they now list drivers for other OS's in the driver section.

    OK I finally got around to trying to put Win 7 on this thing and was under the impression that it had some OEM SLP downgrade rights but none of the installs from different Win7 disc I try grab the bios key correctly. Was I wrong to assume I could use the Win 8 license for a Win 7 install? If so what media do I use.

    TIA
    TP

    Acer AXC-603 Downgrade to windows 7 Instructions

    STEP 1 - Downgrade BIOS/UEFI
    WARNING: DO THIS STEP AT YOUR OWN RISK. IF SOMETHING GOES WRONG HERE, YOU RISK PERMANENTLY DAMAGING YOUR COMPUTER. I MODIFIED THE BATCH FILES TO IGNORE CHECKING ROM ID. IT WORKED PERFECTLY FOR ME BUT THERE ARE NO GUARANTEES THAT IT WILL WORK FOR YOU. I AM IN NO WAY RESPONSIBLE IF THE FOLLOWING INSTRUCTIONS DAMAGE YOUR COMPUTER.
    This step depends on what operating system you currently have on the machine. You will need the files provided HERE (Please download a local copy. I will try to keep this available as long as i can but cant make any promises for the distant future)

    Step1-A – IF NO operating system
    If you have a recovery disk you can also try using it or the recovery partition (Alt+F10 at boot). If that doesn't work, the easiest way to do this is to download the evaluation copy of windows 8 from Microsoft and do a fresh installation.
    After windows 8 is installed follow steps from Step1-B.

    Step1-B – IF YOU ARE IN WINDOWS 8
    Open the “Bios WIN” folder from the files provided HERE. Navigate to the “WIN” directory. Right click on Flash.bat and run as administrator (can also be run from an elevated command prompt from within windows)
    You should see a command prompt popup and it will now downgrade your BIOS.
    If you manage to get through this step, you've won 90% of the battle so cheer UP!

    Step1-C – IF YOU ARE IN DOS / FREEDOS
    I haven’t tried this personally but the following should theoretically work
    Use another machine to download the provided files. Burn them on a CD/DVD that is accessible from dos.
    Boot to dos and use the “cd” command to navigate to the “Bios Dos” directory
    Execute Flash.bat
    If you manage to get through this step, you've won 90% of the battle so cheer UP!


    STEP 2 - BIOS/UEFI Settings
    After flashing the bios press “Del” while booting to make sure the following settings are set
    Set secure boot to disabled
    Set CSM mode to always
    Boot Priority – As per your preference.


    Step 3 - Install WIN 7
    Boot from windows 7 DVD or USB to install windows 7. I personally used a DVD to complete the process so I can verify that is working.
    Hard disk Partitions – If you have left over partitions from previous installations, delete all of them and creating new partitions. You can try installing over the old partitions but I personally haven’t tested this.

    Step 4 - Install Drivers
    Install the drivers provided in the link

    STEP 5 – ENJOY WINDOWS 7

    Windows 8.1

    windows 8.1 down to windows 7 ult


    I just bought an Acer Axc-603-eb11 with Windows 8.1 and with everything in this post i followed including several YouTube videos and other searches and still nothing. I've done the disabling or secure boot, cd/DVD drive to be first priority and still nothing. After I press any key to continue it loads files and than stops at the windows 7 load up screen and does not load. Can someone help me with this? I'm so frustrated and confused I just don't understand. I also purchased online windows 7 ultimate and burnt the file to a cd. I also dont see a CSM mode ..

    I have the same computer as you, but it came preloaded with Windows 8.1. When I was having issues with my desktop, they told me to upgrade my BIOS to P11.B2.
