    G50-80 Win 10/Linux Dual-Boot - UEFI flash to original? Remove Ubuntu


    As stated in the subject line, I am on a Lenovo G50-80 laptop w/ Windows 10 x64. I have recently been experimenting with a couple Linux OSs in a dual boot configuration with complete success. I have though since decided to dedicate another machine to my Linux ambitions.


    My partition is expanded back to norm, all is well with that, however, it still has ubuntu listed in the boot menu and I have been unable to remove it as it keeps being "reinstalled" w/ another {identifier} in BCDedit.

    Is anyone aware of how I can delete the identifier and have it not return (it's obviously stored elswhere) or simply reflash the BIOS to it's original state?

    NOTE: in BCDedit, /fixmbr or /fixboot had no effect. Also the most recent available update to the UEFI had no effect either.

    This is really a non-issue as far as the functionality of the laptop goes, it's more of myself wanting the answer and satisfying that OCD side of myself.......lol.

    Any help would be appreciated. Thx.

    Download Visual BCD Download then run. Ignore the popup error. Go thru the list on the left and delete all items related to UBUNTU.

    Tried


    Tried a few 3rd party boot editors w/ no success, it just comes back. I can delete the identifier in Administrative CMD prompt via BDCEdit /delete {indentifier #} and it does get deleted yet it will show back up again after a boot with another identifier number/letter sequence.

    I remember reading somewhere that the Ubuntu entry is written in another directory or file and that's why it continues to reinstall yet I'm unable to find where it was I read that, nor do I remember what the procedure is.

    So have you tried what I suggested above ?. You are not the first one to have this problem and other people solved it by using Visual BCD. Here's an example:

    Insert the Windows 10 installation media (USB or DVD) or mount the Windows 10 ISO file. From an elevated command prompt, CD to the boot folder of the installation media or mounted ISO file. Run bootsect /nt60 ALL /mbr /force

    That will replace any left over Linux boot sectors with Windows 10 boot sectors.

    Also, you might have to re-remove the Linux boot entry from the BCD store again, EasyBCD is an excellent program to do that with:

    You don't have to actually register to download it. Click the Register button, then just click Download on the next screen and leave your email address and name blank.
