Hi,
I already searched some articles on how to fix this but unfortunately I cant fix it because there is no Boot Mode option available where I can select Legacy instead of UEFI. Can you please help me how to fix it? I also changed the boot order but still didnt fixed it.

Thanks

  • what is the exact model of your noteboo? example v3-571! Some models are no longer coming with legacy mode active in bios!

    The device must have a slot on the chipset & the Legacy firmware specific for it, to boot from BIOS instead of UEFI.
  • Dear @Wis, the current models are no longer coming with bios legacy mode!

    Hi @fror
    1. From a cold start (complete shutdown)
    2. Press the power button and immediatly continually tap F2 key to open the BISO setup
    3. In BIOS go to the ADVANCED menu tab
    4. Select System Configuration
    5. Select Boot Mode
    6. For laptops running Windows 7  toggle and set the boot mode to CSM
    7. For laptops running Windows 8 and above toggle and set the boot mode to UEFI Boot
    8. In the SECURITY menu tab
    9. If the Secure Boot option is available set Secure boot to disabled
    10. Press F10 to and then YES to SAVE changes

    * If this resolves your issue and if you are running Windows 8 and above you should go back into BIOS and enable Secure Boot for the best protection

    Hi egydiocoelho,
    I was trying to explain to the OP why it would be impossible to boot in Legacy mode.  Firstly because he may not have the slot on the chipset & secondly Acer may not have a Legacy firmware for the device.  I hope he understands that he can easily brick his machine by trying flash UEFI to Legacy.  Now it's his turn to explain why he wants to do it in the first place.
  • I know you tried to explain, because some models still have the function to select bios legacy mode! However the current models are already coming from the factory with uefi class III, which no longer contains the function to change to bios legacy mode! Intel itself has confirmed that all devices will only support uefi mode from 2020!
    I think it is trying to install a different operating system than it came from the factory! However it is also possible that some virus has corrupted the gpt boot partition table!
