I've been trying to switch the SATA mode on an Erazer P15609 gaming laptop from Intel RST to AHCI. I'm trying to do this to install Linux on a new NVMe SSD that I have installed alongside the original. The problem I run into is that every time I set the SATA mode to AHCI, the SATA mode revers to Intel RST. Specifically the following occurs:   1 - Set SATA Mode to AHCI in BIOS/UEFI. 2 - Save changes and exit. 3 - Machine immediately reboots. 4 - Return to BIOS/UEFI to find SATA Mode is set to Intel RST. I've tried the following to get around this: * Disabling Secure Boot. * Running Windows in safe mode. * Disabling Windows Boot Manager. * Setting a Supervisor Password. * Setting a User Password.   Nothing I've tried seems to make the SATA mode persisit through a reboot. I'm honestly stumped on this one. If anyone has had any experience with his, and potentially a fix, please let me know.   On a side note, if there's a firmware update for this machine available, I cannot find it. The BIOS details are: Version: 1.07.08RME5_00011 KBC/EC Version: 1.07.01 ME FW Version: 12.0.47.1524   If an update could fix the problem, is there a link to it? ... View more
