If you have an ACER ASPIRE laptop model which comes with UEFI SHELL preinstalled and you've mess it up and you're obsessed with the fact that that little mini firmware interface UEFI SHELL is not showing anymore into your UEFI BIOS this is what you have to do it. I'm sharing this for all of you who get upset with this issue. After 2 weeks spent on Google, asking IT friends (Intel engineers), Forums (askubuntu, askMicrosoft, ask ACER) I found out the solution for RESURECTING that little one back :+1:

P.S. your ACER ASPIRE laptop will work perfect without this mini firmware interface but if you're obsessed on how it can be done..

P.S. 2 I hope I saved you 2 weeks from your life and make a pray for me  <3
