    Cannot access to BIOS/UEFI/boot options on Lenovo h50 with windows 10


    I got this computer used and want to install Windows 7 to it. So I followed whatever instruction I found on the web, got into advanced restart setting on W10, somehow found UEFI firmware settings. Restarted, got into UEFI, changed boot order to USB everything and THEN HDD. Inserted W7 installation USB stick I prepared using Rufus with UEFI and FAT32 settings.
    1) It won't boot up.
    2) There is no Lenovo splash screen when starting up. It either goes directly into W10 or doesn't even turn the monitor on.
    3) Somehow (I think I'm going crazy) "UEFI firmware settings" option in the settings has gone. I don't have that anymore. I check via system information window, it still shows UEFI, not BIOS.

    F1, F2, F8, F10, F12 is out of the question, it does not even look for an input. If I disconnect the HDD, it does not power up the monitor. It insists on booting directly to W10 without any prior screen signal or not booting at all. I've never used a UEFI PC before. I already hate it. So, what to do now? Thanks in advance.

    :)

    No boot option in BIOS after attempting to revert back to Windows 8.1 from 10 on lenovo edge e545

    Did anyone come up with a solution for this?

    I have an E545, originally WIn8.0 that ran out of battery during an update to 8.1

    Now it will boot to a blank screen, and no further

    As in picture above, the BIOS is missing the setup option (so cannot access / change boot order)

    Enter then F12 on boot doesn't give me a list of boot devices to do a recovery (although the BIOS lists the DVD)

    My next step is to pull the HD and delete all partitions, then try the recovery again

    Unable to upgrade to Windows 10, Error message: A system image created using UEFI cannot be restored on a computer using legacy BIOS.

    Hi,



    UEFI BIOS supports two boot modes: Legacy BIOS boot mode and UEFI boot mode. Some devices and operating systems do not yet support UEFI-based BIOS and can boot only from Legacy BIOS boot mode. Choose Legacy BIOS boot mode to allow HBAs and Express
    Module devices to use option ROMs. Choose UEFI boot mode to use UEFI drivers.



    Only devices that support the selected boot mode are listed on the BIOS Boot screen. If you select UEFI Boot Mode, only boot candidates that support UEFI BIOS boot mode are listed on the BIOS Setup Utility screens in the Boot Options Priority list.
    If you select Legacy BIOS boot mode, only boot candidates that support Legacy BIOS boot mode are listed in the Boot Options Priority list.



    Please refer to the below article to Upgrade to Windows 10 using ISO File.

    How to Upgrade to Windows 10 Anniversary Update version 1607 using ISO File



    Hope you can upgrade to Windows 10.

    Let us know if you need further assistance on upgrading to Windows 10, we will be glad to help you.
