Can i disable secure boot while in UEFI mode?

[felipejfc]

Normally yes... and also I can try modding a backup of your BIOS, flash the BIOS I send you and then backup it with this tool, run as admin

If you modded the bios to disable secure boot, please enable a menu to overclock

I see that you already have advanced menus inlocked... for OC you'ld need extermal eeprom programmer to mod ME like $20 of tools on ebay.

Hi.

I Have same version bios and unlocked menu.
but can't change the option secure boot in UEFI mode.

I try using felipejfc mod bios, http://dl.felipejfc.com/bios%20mods/menu...PEJFC6.zip

when flashing i get error 28. "Protected range register are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable Protected Range Registers."

[felipejfc]

after the error you are supposed to press enter, then it will retry with memory unlocked for writing

[riskihajar]

but nothing change, the secure menu still disable.

after press enter, i have this message

"Platform: Intel® HM77 Express Chipset
Reading HSFSTS register... Flash Descriptor: Valid
