Question: **EDITED (provided screenshots for clarification):**

A while back I installed fedora 25, besides windows 10, on my laptop. The thing is, that now I have extra device and I want to remove dual boot (linux).

I deleted linux partitions, but I still have the booting options. I tried running recovery drive of windows 10 through USB, and in CMD wrote boortec /fixmbr and bootrec /fixboot. But every time I restart my device I get to chose system to boot.

So first after turning on my device I get lenovo loading screen. Right after that I am left with a black screen with booting options:
1.[Top left corner](https://i.stack.imgur.com/A93Vd.jpg)
2. [Bottom left corner corner](https://i.stack.imgur.com/T8zUY.png)

Now when I deleted linux partitions it obviously cannot boot into fedora and every time I have to choose WBM.

How can I restore original windows 10 booting order?
I read that reinstallation of windows might help?

Answer: 
Or, even easier, just hold `Ctrl`+`Alt`+`Shift` and drag and drop your file/executable.

Unless they changed that from 17.3 to 18.x, but doubt it.
All that is super fancy, a simple text file, go to properties, permissions, tick allow «executing file as program».

From now, simply by double clicking this file, the tasks will be performed. (bash!)

For example, this will launch Firefox, if installed.

```
#!/bin/bash
firefox

```

How cool is that?
