Hi,

 

I bought 4 Acer Aspire XC 703 (P/N: DT.SWZEB.001) and there isn't option to change UEFI to Legacy BIOS.

 

Bios version is P11-B1 (06/16/2014) but there isn't update at support web.

 

can you help me?

 

thank you

    thank you, but in boot options panel there isn't Launch CSM option.

     

    I'll report to customer support.

    it doesn't matter, I've had to return four machines like this because they have a big problem in BIOS. They can't boot with another device (USB, CD/DVD, ...) but Windows Boot Manager and there isn't BIOS update that resolv yet. You can't install Linux or another OS.

     

    Acer support hasn't given solution to this.

     

    What a pity!

     

    thank you to all.

    On my T3-600 Acer calls it Authentfication. In BIOS Authentification/Secure boot /Disable

    When booting up from USB the usb will show UEFI as long as secure boot is disable I have had no trouble installing Linux Mint.

    Hi!

     

    do you know if Aspire XC-603 BIOS update is compatible with XC-703?

     

    If so, I'd try to update to resolv this bug.

     

    thank you

    All sorted now, a Bios update has been published that adds CSM boot to the XC703 bios. I have flashed the Bios with it, and yep... Launch CSM Boot now appears.
