In order to resolve issues related to booting and the start menu, I am trying to run a repair installation of Windows 10.
The computer was delivered with a pre-installed Windows 7 without any installation disks (delivering those seems to have fallen out of fashion, unfortunately) and was unintentionally upgraded to Windows 10 when the user ran into Microsoft's X means accept trap.
As is suggested in this forum, a repair install of Windows 10 can be done despite not having any installation media by using the Windows 10 ISO. I have thus prepared a bootable USB storage with the ISO file generated by Microsoft's MediaCreationTool.exe.
Upon booting the destination computer from that device, however, I am confronted with the following message (in German, my translation below):
In English:
Apparently, you have launched an upgrade and conducted a system reboot from the installation media. If you wish to continue the upgrade, remove these media from the PC and click "Yes". In order to run a clean reinstall instead, click "No".
I am confused by this message and do not understand what it is trying to tell me:
- The premise seems incorrect. I have not yet started anything, least of all an "upgrade".
- As I have not started anything, and as I do not want to run any "upgrade" (I have not purchased any newer or higher version that the installed OS could be upgraded to), I do not want to continue the upgrade. Hence, "Yes" seems like the wrong choice.
- I want to repair the existing installation. I do not want to entirely reset the system. Thus, "No" appears to be the wrong choice, as well.
How do I proceed from this point to reach any repair installation options?
