How to change from UEFI to Legacy BIOS?

ANONIMNIQANONIMNIQ Posts: 11Member

Hi,

I have PACKARD BELL IMEDIA S2883 with preinstalled Windows 8.1. BIOS is UEFI and i can't fint option to change it to Legacy BIOS. In UEFI it's won't detect legacy boot devices even with Secure boot option disabled and Legacy USB enabled. Is there any way to use standart Legacy BIOS? Any help will be appreciated!

    Hi ANONIMNIQ,

     

    Could you tell me what your current BIOS version is? Also, could you send me a private message with your Serial Number? I'll see what I can track down for you.

    sorry, no other suggestions.

     

    maybe contact packard bell support and ask about Legacy mode.

    After a week talk with technical support, this is their final answer. I'm speechess!

     


    Regarding your query, I would like to ask you where do you reside now.

    If there is no region to select, then I am sorry to inform you that there is no other option.

    You might have to check with the local technician or contact the place from where you bought this unit.

    I recieved Cory's answer. In my case, the solution is to update to BIOS P11-B2. Now I have Launch CSM option and legacy media is detected, but I still have some problems to boot from the devices - When I trying to boot, my machine reboot, or get mesasage ""An operating system wasn't found. Try disconnecting any drives that don't contain an operating system.". I'm not sure where is the problem. I try to install seccond OS to my machine, but even live usb distributions won't boot properly in legacy mode. Is it possible to have Windows and Linux on the same machine?

    BTW I don't have DVD drive, so I only tried with usb installations.

    under Legacy and CSM, you can have 2 OS.

    do you have also secure boot settings?

    Yes, Secure boot is disabled and Launch CSM is Always.

    I tried with Fedora live usb, and in UEFI mode it boots properly, but in legacy mode when I try to boot from the usb it shows me a message "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system."

    With Launch CSM enabled it's normal to stop detecting my current Windows 8 HDD partition, but I don't understand why it's not boot properly from the usb devices.

    try to boot this .iso from Legacy and USB:

    http://www.partitionwizard.com/partition-wizard-bootable-cd.html

     

    it's partition wizard bootable live iso and i'm curious if it will be able to boot.

    ok, I tried this and it's work properly - boot with no problem in legacy mode. So... what could be the problem with the other installers Smiley Sad

  • IronFlyIronFly Posts: 17,890ACE Trailblazer

    probably Fedora switched to UEFI boot to have windows 8.x working too, without messing with BIOS settings, apart maybe secure boot.

    But that's strange, because I even tried to delete EFI folder from USB stick and unplugged my Windows HDD, but the result is the same.

  • IronFlyIronFly Posts: 17,890ACE Trailblazer

    check if the fedora partition on the USB is marked as active.

     

    which kind of software are you using to burn iso to USB?

    rufus?

    I use this to burn iso to usb:

    https://fedorahosted.org/liveusb-creator/

     

    I make the usb partition active with diskpart and now when I try to boot from it I get this:
