Nope. UEFI boot mode still grayed out. Even with all possible passwords set, secure boot and tpm off, and even after saving changes and reboot. I wonder if it has something to do with the two NVMe ssd's that i got installed. Maybe it needs an SATA drive to work out?...

First of all, thanks for the answer!

Well, that's actually the first thing i ever do! Don't wanna anyone of my dumb friends messing around with my settings, but the only option that it still gets grayed out is the boot mode, even with secure boot and tpm sets to disable. That's why i was going kinda deep into bios mods!...

Well, what to say? It worked flawlessly! I installed de TI version, and it rebooted like as when we have a cmos reset, and it just got working. But i still have no idea what did you have done to make this magic happen! Thanks a lot, dude.

Could you explain or send me a link to learn more about exactly what did you do? I'm actually really intrested right now, ive spent 10 hours yesterday looking for a solution and would appreciate it if you could teach me.

Again, i'm so grateful! Thanks, dude! (wrote through AN517-54!)

Edit: Btw, is there any way to enable...

Hey guys! I've recently found out this amazing forum where people talk and discuss about electronics repairs and i'm actually amazed with everything that here's have to offer.

Oh well, i came here looking for a simple bios file in order to get my main laptop working again, but after a while trying to figure out what the hell was going on, i'm quite concerned that it would be worse than i tought. I was fooling around with Mr. Smokeless's UMAF BIOS mod, looking for a way to enable CSM compatibility and legacy boot on my device.
