    BCD issue on a Lenovo. UFEI? HELP


    Basically i was messing around with MSconfig the other day and i removed either a critical startup action or file because i restarted my computer and it booted to the BCD error screen. I have a windows 8 recovery USB but It wont let me boot from there since this laptop is a freaking Lenovo with UFEI. If i cant access f12 how the FFFFF am i supposed to boot this computer to the usb? Please guys i came here once before and i did not receive much help but a couple of links that did no help AT ALL.

    The error i am getting is: Recovery
    File:\ BCD error code 0xc0000034

    Dude does F2 or any other key defined by lenovo allow you get into BIOS?

    The error code ur receiving is a corrupt boot sector, and it can be fixed by running startup recovery.

    I dont think so man. Ive been reading a lot and it says that new computers with uefi dont have start up key options such asf f etc. The only thing i can access right now is the UEFI screen.

    Forget about links you have been reading.
    You CAN and it is possible to get into BIOS.

    Do you even know the function key needed for BIOS? it's F2 or F1 or F10 or I don't know.
    As soon as pc starts booting you need to keep pressing one of those key until you see BIOS screen.

    EDIT:
    Please provide name, make and model of your machine. the key depends on these things.

    okay i found it. it gives me 4 options. Normal start up, BIOS setup, Boot Menu and system recovery. which one do i do, also i dont want to lose all my files because in the system recovery option it says i will lose them if i didnt back them up. But ive read that for this type of error i shouldnt have to wipe my computer

    First of I do not want to responsible for any data loss.

    1. Your stick needs to be inserted into USB port.
    2. In order to boot from USB you need to enter BIOS setup and there switch from "secure boot" to "legacy".
    3. while in BIOS, in boot order options USB needs to be listed as first option
    4. save BIOS settings and reboot

    NOTE: Switching from "secure boot" to "legacy" will prevent you to boot into Windows installed on HDD.
    You will need to switch these settings back later in order to get into Windows

    Yes,
    Use F5 and F6 keys to move your USB to the top on the list.
    Under "Boot mode" UEFI needs to be changed to legacy
    Finally Press F10 to save and reboot
