@Kebicle - Before I do the edit, can you already see "Boot Mode" Option on Boot page? Just want to make sure the setting itself does not need revealed too
Also, you can see "Secure Boot" option there too, correct?

@Lost_N_BIOS Yeah I can go to boot mode but when I enter the submenu (if thats what its called), UEFI is the only option there

Thanks, please see my edit question above about secure boot, then I will do the edit for you

Yes I can also see secure boot and am able to enable or disable it

@Kebicle - Secure boot needs to be disabled to run Legacy, at least I think so
Here is mod BIOS where you should be able to see Legacy now. If it's visible, but still does not function properly, let me know, I think some other item connected to why it was hidden may need nulled out.

@Lost_N_BIOS Thank you so much. I will be flashing it asap (taking apart laptop again now). Any idea on how I would know if it is functioning properly?

You're welcome! If you can install in legacy mode If whatever caused you to want/need this works now, then you know it works MBR partitions should be bootable in Legacy mode, UEFI/GPT ones would not (or maybe they can with Secure boot enabled, on legacy, I'm 100% sure)
Why did you want it anyway?

Leave system apart in case we need to apply that follow up edit I mentioned

@Lost_N_BIOS Yeah Ill leave it apart. Flashing in two minutesh ish. Wanted the option to install older windows versions such as windows 7.

You can install Win7 in UEFI mode to GPT partition as well, Legacy is not needed for that.

I'm curious to know if Legacy boot can be unlocked as well; I assumed this laptop didn't have CSM or legacy oproms available. Even with the unlocked settings I have now (the fd from first post) and SecureBoot disabled, I still only saw UEFI as an option there.

@Espionage724 - I forced legacy option visible (unsuppressed it), may need follow up edit due to something I noticed tied to the suppressed setting, but we shall see
BIOS contains orom vBIOS (many) legacy, but does not contain legacy RST (so no legacy RAID) - Take that back, I see orom RST at 501737AB-9D1A-4856-86D3-7F1287FA5A55 >> EFI one is at 382F560D-17A9-4887-BD9C-EB439C1CC482
However, CSM is not mentioned at all in the BIOS, so legacy may not be possible unless CSM (While hidden/missing) is enabled by default when legacy is selected

@Lost_N_BIOS While it is true you can install win7 in uefi to gpt, you need to have CSM compatiblity which this motherboard doesnt have. therefore making it impossible over uefi.

@Espionage724 Ill update you if I sucsesfully install 7 using legacy

@Kebicle - see my edited reply above at #42 -
As for Win7 and CSM/GPT, you should not have to have CSM enabled to install Win7 to GPT, unless something is legacy only (That's the only time you need CSM when secure boot is enabled and installing to GPT), but you would need secure boot enabled.

* Edit
@Kebicle - Here is follow up BIOS edit, in case first one fails to allow legacy install, or fails to properly allow legacy selection, or on reboot it's set back to UEFI etc -

@Lost_N_BIOS Just flashed :) time to test. As for the uefi windows 7, Im 99 percent sure and the reason has something to do with the boot files, give it a google when you have time.
