Since installing Win7Loader release 5 (with great success - TY Hazar for option #2!) I have discovered my bios is slic 2.1 enabled. (Dell Inspiron 531 - BIOS ver 10.1.13). Would there be anything to gain if I could uninstall Hazar's loader (option 2) and use a cert and key instead (option 1) ?? I have noticed a slight delay in by normal boot time ..no biggie..but without the grub mbr would that delay go away. Thank you.
