    I’ve got tremendous help from you guys, because I messed up in the soldering department.
    Ubuntu is running happily, but OSX got trampled in the process of deleting an unwilling HighSierra.
    When I do a NVRAM reset, I cannot install OSX off a USB stick.
    When I do the EFI fix, and install Ubuntu on a separate partition, I still cannot install Sierra.
    Sometimes the installer runs fine and stops with 20 seconds left.
    What is the solution ?


    Saturday in Belgium and the sun is shining.
    I managed to install OSX by using target mode from a Macbook Air with El Capitan ( and a firewire adapter)
    Downloaded EL Capitan from App Store and directed it to the HDD of the MBP.
    In fact I installed an OSX on a sleeping MBP. Wicked Appleness.
    Close the bridge, reset NVRAM and SMC
    Once El Capitan was installed on the HDD of the MBP 2011, I shut it down.
    Ran the Adam EFI fix, rebooted in safe mode the new El Capitan and it worked !!
    Opened the bridge.
