Bios not detecting any HD's in UEFI mode aw18 a10 bios

Decided to do a fresh install however none of the hds will not show up in UEFI mode, only in legacy. (in AHCI or raid) The SSD I'm attempting to install on is GPT formatted with no volumes. I'm running a TB Samsung 850 SSD unlikely wife will let me get another one. At the moment I have no need for raid, so I think I will use AHCI so I dont have to stare at that screen everytime I boot. Any ideas why nothing is showing up? SSD was previously running in raid, formatted it, removed system partition, converted to gpt (its all just unallocated gpt space now) but still wont show up in UEFI.

 

This is fairly common. If you have Secure Boot enabled in the BIOS, try disabling that and see if they are detected. You can use UEFI without Legacy/CSM support without having to enable the Secure Boot cancer.

Secure Boot cancer requires that the drives have a "signature" in order to use them. That's to protect you from yourself and block "dangerous" upgrades that the OEM did not make any money off of.

 

secure boot is off and drive was activated in. but none of the 3 hds show up in uefi

 

Did you do a diskpart clean command on each drive? After I re-read your first post is it not clear that you did.

Administrator Command Prompt:
C:\

• diskpart
• list disk (shows a list of drives)
• select disk _ (the _ is where you type the number of the disk you want to select)
• clean
• convert gpt (or mbr if you prefer that as I do)
• repeat for each drive

 

I did it on the ssd that im attempting to install it to. Attempting to reinstall once more, same thing have to enable uefi with legacy for anything to be visible, setup confirms that its a gpt disk and shows an msr partition on it

 

Is there a reason you have a problem with Legacy support being enabled? Having the option to use Legacy BIOS is a hallmark characteristic of a superior laptop. It's the crappy disposable turds that lack that option.

Are you trying to run 980M video cards or something? Pure UEFI really sucks... not sure why you would actually want to have that configuration set up on purpose unless you are left with no option due to Maxwell MXM GPUs not being engineered correctly. All you are doing is limiting your options by disabling Legacy support. There is no benefit to pure UEFI mode other than having a partial workaround for the flaws in Maxwell GPU architecture.

The drives not showing up is courtesy of Micro$oft and their hardware signing idiocy. If you are convinced there is some kind of mystic value to seeing UEFI when you look in your BIOS you can set UEFI with Legacy Option ROM and bypass all of these worthless exercises.

 

no 980m yet not until they sort that business out, more of a curiosity at this point. Disk does show that it is an efi partition so suppose all is well, curious why it wont show in uefi mode only though.
