I am about to update my B760M Pro RS/D4 PC from Windows 10 to Windows 11. I am going to install Windows 11 on a new M.2 drive. Afterwards put the old drive with Windows 10 into the second M.2 slot in order to copy some files from old to new drives. Will the PC automatically boot from the first M.2 slot? Or am I asking for trouble by having two boot drives? Thanks for any comments & suggestions. |

You can set Boot Priority on the "Boot" screen of the BIOS - you should be able to tell it to prioritize the new Windows Install - also, you can use "Boot Override" which is typically on the same BIOS screen as the "Save & Exit" option, to manually go to one install or the other, depending on what you need to do. But you should be able to tell it which drive to boot to on the "Boot" tab of the BIOS. Which ever one is at the top is the one it will prioritize. |

No worries, happens to the best of us. Only reason I know this is similar experience, I had a few different installs of Windows and wanted to get old files off of it, I actually had to set the boot order because for some reason the motherboard I was using at the time picked the old drive as the first priority. ------------- AMD 9950X3D - Asrock X870E Taichi - 2x48GB G.Skill Trident Z Royal Asrock Taichi 1650W PSU - MSI RTX 5090 Liquid Suprim SOC |
