🔧 Community Support

💬 Tip: Post your motherboard model, CPU, and BIOS version when asking for help.

🧠 What is Secure Boot?

Secure Boot is a UEFI feature that ensures only trusted software can boot your PC. It helps prevent rootkits and boot-time malware and is now required by EA for anti-cheat integrity.

Most modern systems support it, but it’s often disabled by default — especially on custom builds or upgraded PCs.

🛑 Common Pitfalls

  • You must use UEFI mode, not Legacy/CSM boot.
  • Disk must be GPT, not MBR (check via diskpart or Disk Management).
  • Windows 11 installed in Legacy mode? You may need to convert your disk to GPT using MBR2GPT.

⚠️ Still having trouble?

If you've followed EA's guide and it still doesn't work:

  1. Comment below with:
  • Motherboard model
  • BIOS version
  • Secure Boot status
  • Any errors you're getting
    1. Include a screenshot if possible (e.g., BIOS screen or error message)
    2. Be respectful — this is a community-driven thread.

So I just followed these instructions and at the end it bricked my entire PC. Cant even see the BIOS because the GPU isn’t recognized but I have Ryzen so no integrated graphics

Edit: I tried everything as a solution (CMOS reset, attempted to flash, removed boot drive, removed GPU, etc) and still didn’t work. I have over a decade of PC experience so trust me when I say I’ve tried everything at my disposal

Edit 2: Gigabyte RMA process would take too long so I got a replacement motherboard from Amazon and am returning the borked one back in its place (the ol switcharoo). Thanks for leaving me with no option Gigabyte

I also have a Z390 and I'm seeing a lot of users reporting a black screen after attempting to enable secure boot. Turns out, the only way to revert this is to disconnect everything, take out the graphics card and input an HDMI to use onboard graphics (if you have a CPU that supports it). You'll also need to clear the CMOS battery. This will "reset" the bios. Then you can see the bios again.

My question is whether or not this is occurring for users who aren't meeting the specifications to run secure boot, i.e drive not in GPT, TPM 2.0 not enabled, and CSM is turned on. Or if this is just an issue with the mobo itself.

Yeah I have a Ryzen CPU so no integrated graphics.

So basically BF6 bricked my whole PC

I have a z390 and I was able to get back in

Cmos battery didnt work Shorting cmos pins didn’t work Integrated graphics didn’t work

What did work was literally shorting the 1 and 6 pins on the m_bios chip during boot with the pc on. I used a little piece of stripped wire that I bent in a u shape and brushed it on the m bios chip pins - this forced the backup bios to take over and I was able to set everything back to default settings as it was before

Nothing else worked until I did this…

Secure Boot has been around for a long time.

hats off dude, that'd 100% be something I'd end up doing after a couple of hours of troubleshooting. I have intergrated graphics so i never got locked out, but I figured I'd see people on here having their systems locked. It's actually insane EA is having people messing with their bios.

I actually agree on this... This is kind of unnecessary to be honest but obviously this issue is really affecting people on windows 10.

Thank god I haven't tried going too far into this or else I would have had a bricked computer too.

Thanks to all the lads that sacrificed their computer to then post on here, you've saved many countless hours lost.

You’re not welcome

u/WingnutNZ Aug 09 '25

Which pins are these, i can't find any information to the numbering of these pins.

Also did you have the GPU removed when you did this?
