Please help to fix this problem Here I used THOMSON TH-int8win16l (windows 8.1)TABLET. When I turn ON its showing this error EFI shell version 2.31 (5.8) shown in the photo. Then I tried to type “EXIT” then it enters to bios then I pressed F3 for optimized default. No use. Here I have attached the photos present in the Bios. How to fix or install OS in this situation? Help me.
