Bootcamp problems

I tried to install windows 10 on my iMac (Retina 5k, 2017) with the MacOS Mojave 10.14.5 software version but while the bootcamp was doing its job, suddenly I had a power outage. I restarted it. It apparently created a partition for the windows, although it didn't open windows installer or anything of that sort.

My USB Drive of 64 Gb remained unchanged (I think).

I tried running bootcamp again and it had the option of choosing either the macintosh hd disc and creating a new partition with windows on it (which I don't really want to) and the option of deleting the disk that was supposed to have the windows and creating a unique partition for windows. I chose the 2nd option, however this time, after choosing that option it said that there was no usb drive connected to the system (but it was). Still I did it, I chose the proper ISO file and started it. After the process was done, the Mac restarted and after a couple of seconds, it appeared a flashing image of a file with an interrogation mark on it. I shut the mac down and powered it back on. I started normally again. And that's how it ended. Can someone help me?

This a diagnostic step. It does not modify the system.
