I've recently upgraded my PC, specs will be below. Running W10. After building, I was not able to boot into windows using the same drives I previously used. I was able to change UEFI mode to CMS to boot into windows, without formatting drives. I believe CMS is only a temp fix, and I am hoping to find a more permanent solution. I now cannot load into BIOS unless I unplug all of my SSD/HDD(tried everything, only unplugging works). Are there any cons of using CMS vs the usual UEFI?

System runs just fine, however access to BIOS will be nice. I am also unaware of any cons using CMS.
