    Windows 10 Upgrade failed on laptop

    Hi guys, I convinced my friend to upgrade to windows 10 on his laptop and it failed leaving it screwed.

    The laptop is based on a Clevo W350ET chassis.

    When you turn it on it goes to a screen saying 'Recovery Your PC/Device needs to be repaired, A required device isn't connected or can't be accessed, Error code 0xc000000f'.

    Any options like revert to a previous built, system restore or whatever do not work.

    Any chance of saving the current install or will I have to reinstall everything? My friend has old programs he is concerned he cannot get anymore.

    In my opinion, reinstall is the only option.
    You can do an in-place upgrade install which will allow you to keep your settings, files and apps.

    No, It is not necessary.
    Assuming your Win 7 is a genuine copy and has already been activated, Win 10 will be activated automatically after install is completed.

    You have one problem.
    Do I understand that you are not able to login to the computer?
    If that is the case, I am afraid a Clean Install is in order which will not be able to keep the old programs you mentioned.
    You will need to use another computer to download Windows 10 ISO > burn it to a bootable DVD or USB and then take the bootable media to the computer in question.
    Then you will need to access the Boot Order ( one of your F keys. Usually it is F12, or 2, or 10 )> change the boot sequence to CD/DVD or USB > insert the bootable media > restart the computer > Installation will begin.
