Does the boot drive need to be in GUID partition table mode when using optane to accelerate a secondary hard drive that IS using GPT?

I am trying to use a 32GB Optane module to accelerate a secondary hard drive that stores most of my files. I am using an Asus Prime Z270A motherboard and an i7-7700k. When I first tried installing the Optane drivers after plugging in the module, I got an error telling me to change boot device control setting in the BIOS to EUFI Only, the same as this guide from Asus. http://dlcdnmkt.asus.com/microsite/Optane-Memory-SOP.pdf http://dlcdnmkt.asus.com/microsite/Optane-Memory-SOP.pdf After changing the setting and rebooting, I am unable to boot into windows because i get an error that there are no boot drives. This is because windows was installed in Legacy mode and the drive uses Master Boot Record and not GUID. My question is, do I have to change my windows boot disk from MBR to GUID partition table even if I only want to accelerate a different disk that is already running with GPT? If so, is there a way to do this without losing data on the boot disk? (This guide says there is, but doesn't go into much detail on how to back up the data https://www.intel.com/content/www/us/en/support/articles/000024558/memory-and-storage/intel-optane-m...

Hi _mu110_,

 

 

Thank you for contacting our support community.

 

 

We understand your situation regarding the Intel® Optane™ Memory.

 

 

We would like to inform you for secondary/data drive acceleration support, Intel® RST Pre OS UEFI driver 16.0.2 or later is required and this is done through a BIOS update, so we recommend you to contact your motherboard vendor in order to confirm if your system has a BIOS update available that contains the Intel® RST Pre OS UEFI driver 16.0.2 or later.

 

 

In case there is no update, then you will need a system that has the proper BIOS support. For more information you can check these articles:

Also, for Secondary acceleration, the drive is required to be formatted with a GPT partition as well as the boot drive.
