Question: I want to make my Minecraft Skin Viewer not have to be put into the Terminal like

```
User@ChrUbuntu~$ Wine '/home/user/Documents/MCSV.exe'

```

I just want to be able to double click the .exe file and it will run. How can I do that?

Answer: 
choose legacy mode on bios and then try [`boot-repair`](http://sourceforge.net/projects/boot-repair-cd/files/?source=navbar).
Try installing Boot Repair in a live CD/USB session. It can work miracles for a missing entry in grub.
