NON-UEFI BIOS Mode prevents our solutions from launching, so please make sure it is UEFI.

To find out the BIOS mode do this:

1. Open msinfo32, by typing msinfo32 in windows search.

1. Go to System Summary.

1. Find line called BIOS Mode, if its UEFI, then you are good to go

In case if your BIOS Mode isnt UEFI, then you can either do MBR2GPT, that doesnt work for everyone, or you can reinstall your windows.
