I have the following situation, please anybody help:

I have acer swift 3. Wanted to install Ubuntu alongside Windows 10. After installing Ubuntu added grub into boot efi. 

Now I got: 

Failed to Open EFI\BOOT\grubx64.efi


and see "Security Boot Fail" 

Wanted to use live Ubuntu to fix it but somehow my bios has a password although i did not set it. How Can I RESET my BIOS PASS and fix my problem? Thanks
Or how can i boot from USB?

P.S: Boot Manager is not available(F12). Do not know why. CMOS battery disconnect did not help(waited 10 min). ((((((((((((((((((
