    I've created a new thread with you post which was on a thread that was 3 years old and totally unrelated.

    What version of macOS was on the MBP before you did the upgrade? What version did you try to upgrade to?

    Good afternoon Sir. Thanks for your help. I have no idea what the previous operating system was . I think it was el capitan but I was trying to install Sierra on it.. It started installing and after 12 minutes says that it cannot install and then redirects to restart pressing the D key.
    Did that and then got the 3403D error code. I was trying to be smart and now my wife's Mac is crashed. I fear no one but her.. Please help me out or tell me how to solve this. Thanks in advance...

    You will need to probably run the Apple Hardware Test to check that the Mac is in full working order. You have have picked up an issue that has been manifested itself. You need a Mac OS disk or download from GitHub to check the mac is ok or not. It should run Sierra fine.

    Ok. Someone advise me to restart by pressing the command option r keys at the same time . Got to use the safari and have the four options but it does not go back to the original Mac OS system and it just tries to reinstall the one that crashed it. Think I need a start up disc or to access the hard drive in order to erase some files since it seems that I don't have enough disc space to install the newer version.Please help me and indicate How do I restart from an external unit? how do I get to the hard drive to back up and erase some files ?
    thanks

    Maybe you could post the details of all your Macs, models etc. so that we could suggest some solutions.

    Do you have any good Mac support tech/dealers fairly close by that you could get to help and assist you???

    You can get Mac OS X Snow Leopard, Mac OS X 10.6 Snow Leopard - Apple, from Apple.

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    I'm sorry, but I have to ask, because it simplifies any restoration process we might suggest. Do you have a backup of your wife's computer?
    I used to be conceited but now I'm perfect.

    Have a read through here, it should work even with a time machine backup:
    Restore your Mac from a backup
    Restore your Mac from a backup - Apple Support

    Other backup methods using Carbon Copy Cloner or or SuperDuper use a different method.
