I try to remove the first page of the site to get the folder inside index page set as home page

Hello I try to remove the 1st page of the site. I want to have only the 2nd page who contains 4 visuals. The issue I have is folders within Index page cannot be set as home page. So i don't know how to proceed.  I have no other choice to proceed this way to avoid to have the visuals cropped in the mobile version . Thank you so much in advance for your help. 

site : missionpossiblegang.com

Code: 1604

I'll be happy to have only this page.  thank you

Did you solve it? I see 1 section only, your screenshot has 3

No i didn't solved it 😞

1. Start IIS manger: Go to run window and type “inetmgr” and hit enter to open IIS web server in your windows system.
2. Select Default Document Option: Now go under sites option in left side bar and select Default Web Site.
3. Select Default.htm (Page to be disable)
