========================
Detailed description:I recently have been having issues with my Q525UA laptop, that conveniently starts happening after the warranty is over. Every half hour or so it would give me a WHE error, so I spoke with ASSUS and they said that the problem was hardware and that I should reset the BIOS to default, however when I did that the computer boots back to BIOS and it doesn't detect a boot device regardless of there being a drive and a loaded OS, so then I was reading on forums that there is an issue with specific UEFI BIOS that don't allow Windows to boot with Secure Boot so to do that you have to disable Secure boot. But I still was unable to get it to recognize because the drive was coming up under the PORT3 rather than PORT 0 and I was reading farther and it says that you have to have a specific type of setup to USE secure boot but you can still enable CSM Support to run a regular hard drive.

But I am concerned that running the computer in CSM mode is what is causing these WHEA errors

I have windows 10 installed on a gpt disk (ssd) but i can't boot without csm enabled,if i try to it just takes me to BIOS and doesn't show my ssd as a boot option. I want to be able to fastboot hence I want to be able to disable csm.

in gpt disk, in first partition is invisible to users and it formatted to FAT32 . Name of the partition is EFI and the partition contains only EFI boot files including fw boot.
