Hello support, i wanted to disable secure boot for my desktop.
i have a pavilion Elite HPE-532s Bios 7.15 i followed the step in many posts but i don't have it under "Security" ?
i'm on window 10 64bit UEFI mode.
i wanted to disable it because i have a new graphic card GTX 960 and it stuck on the HP logo at the boot all the time when i use the new card.!!
I tried to disable the security slot but whatever i do that i get black screen for both my old and new card so i have to reset the bios settings.
Help me please.
Solved! Go to Solution.

Secure boot is not the problem. Secure boot will protect you against root kits. Take a look at my post here about a GTX-950 and I have a HP Envy 750-124
If you need pictures let me know but what I done is go into Bios and set my Nvidia as primary then disabled the Integrated video. Tell it to save then shutdown. swap cable back and start it up

I can make my old Nvidia as primary because I can access the bios with it but when I put the new card, I can't pass the Hp logo screen even if I hit Esc really fast I get another screen but get stuck on it and some minutes later some sounds and then nothing.
you have a new bios update 2016 mine is from 2013 and is the last.

I suspect you are not seeing a Secure Boot option because you are not using UEFI.
You can confirm UEFI or Legacy by running this command in the windows desktop search bar: msinfo32
Under 'System Summary' you will see "BIOS Mode"
If it says Legacy then it's likely that your new graphics card only supports UEFI and you will need to get one that is compatible with a Legacy BIOS.
There are Hybrid graphics cards and others that have a physical UEFI/Legacy switch which are compatible with both.
Here's an example at this link: MSI Hybrid Graphics Cards
Here is an example of a SapphireTech graphics card that is compatible with both UEFI and Legacy BIOS.

it was legacy then I checked on the bios to boot with UEFI so I needed to change windows boot from legacy to UEFI and succeded then I disabled legacy from bios and left only UEFI boot but still nothing!!
what else can I do?

Please do one more thing for me. Sorry, I still question wether you have a UEFI system. Are you able to use your mouse pointer while in BIOS/UEFI? Or are you navigating BIOS with your keyboard?
Does msinfo32 still show Legacy?
Please check how your hard drives are partitioned.
Right click the start menu and choose 'Disk Management'.
If your boot drive is partitioned MBR then it is a Legacy system not UEFI.
UEFI uses GPT [GUID] partitions.
Also curious, exactly what brand/model GTX 960 are you using? MSI, Sapphire, EVGA, etc.

It was showing Legacy in msinfo32 but I convert it from mbr to GPT with some command lines now it shows Uefi in msinfo32 and everything is OK but whatever I put the new card it doesn't work stuck in the hp boot.
I use the keyboard in Bios. no mouse.

can some option disappear in the bios if I update windows ? I had win7 and now I have win10.

Thanks for the additional information.
Here is my diagnoses/opinion:
I don't think you are going to be able to get the GTX 960 to work with that system.
Why it won't work in UEFI/GPT:
It won't work in UEFI because [I suspect] the GTX 960 is a UEFI only card and you need to disable secure boot in order for it to work. Your BIOS is only "UEFI compatible" originally intended for Windows 7 [which does not support secure boot]. If you cannot disable secure boot you cannot use that card.
Why it won't work in Legacy/MBR:
It won't work in Legacy because it is a UEFI only card.
Revert back to Legacy/MBR and use a graphics card that has a Dual BIOS/Hybrid BIOS or one that specifically supports Legacy BIOS as shown in one of my previous posts.
Some other things to consider:
Does you PSU have enough wattage for this card? I think it requires a minimum 400W PSU.
Did you connect the auxillary power connector?
Did you tried disabling "Intergrated Graphics" in BIOS [if applicable]
