    Changing boot order when BIOS is set to UEFI

    Heys guys, I'm hoping I can get some help with this. I have a Lenovo y410p. It has 2 drives, one with the OS (120GB SSD 40mm N.2 NGFF) and a data drive(1TB HDD)

    My computer recently crashed when I was installing a piece of software, (Bentley MX Road, it's a road alignment package.) When I restarted my laptop I was greeted with a lovely message informing me that winload.efi was corrupt. That was fine so I did a bit of research to fix it involving getting a recover DVD and going to the command prompt to rebuild BCD. That didnt work for me as it didnt detect windows. I tried to see what was up with the SSD using DISKPART & CHKDSK. Neither of these showed the SSD. They only showed the HDD

    So now to take a step back, In order to get the recovery DVD to boot I had to change the boot option in the BIOS from UEFI to legacy support. This showed me a list of bootable devices (HDD, SSD, DVD etc.) When UEFI is selected only one option is available which is the Windows boot manager. This is followed by the serial number of the HDD which does not have any OS on it.

    I have tried using f12 which give me the windows boot manager option and nothing else. When I select this, it boots me into the error message.

    So to get to the root of this, how can I change the boot order when the BIOS is set to UEFI so I can repair the winload.efi file on the SSD. Thanks for any help.

    You change it the same way as before. Usually you can do it withe the OEM software installed on Win8.

    You may have to turn off Fast Boot if set.

    My issue is when the BIOS is set to UEFI, I only have one option in the boot order which is 'Windows boot manager'. I have no DVD drive, SSD or HDD. When I change the BIOS to legacy support, Windows Boot manager disappears and I am given the options of SSD, HDD, DVD or network.

    Normally, you do not need to change the UEFI firmware (BIOS) settings, for example, the boot order of drives, enable Legacy BIOS boot mode, enable Compatibility Support Module (CSM), or disable Secure Boot.

    - Connect your USB flash drive or insert your DVD.
    - Shut down your laptop.
    - Press the NOVO button. The system loads boot options.
    - Select the BOOT MENU option.
    - Select your USB/DVD from the boot menu.
