I have Acer Aspire A315-31 with preinstalled endless os .I deleted it and put windows 8.1 in it .Everything was going correct. But when I tried to dual boot windows 8.1 and Ubuntu 14.04,it failed.I changed the boot priority order in boot manager.When I exit saving changes ,it showed security boot failed .When I wants to enter in boot manager to change boot priority order using F2,it doesn't opened .I entered windows through boot menu. Plz. Help me .

    "security boot failed" - easy way is to turn off UEFI by going into the BIOS, create a system password (write down and put in a safe place you will remember), and reboot. Under BIOS/Security there should be an "Erase Store..." selection. Erase and reboot. This should take care of the security boot issue.
