Hey everyone! I'm in the process of upgrading my laptop and I'm planning to install a second NVMe drive. The catch is that this drive has Windows and all my files from my previous laptop on it. I'm wondering if there could be any problems that arise from this setup. Should I just reset the second NVMe drive, or is there something else I should consider after backing up my files?

When you boot after adding the new M.2, there are two possible outcomes. Most likely, you'll boot into your original Windows installation. In that case, just format the M.2 using Disk Management. If you boot into the second Windows installation, youโ€™ll need to reconfigure the boot order in BIOS or use the boot override option. You can even create a shortcut to quickly access BIOS if needed!

You might need to adjust the boot order in the BIOS, but overall it shouldn't cause major issues! Just make sure everything is set correctly when you plug in the new drive.

You'll likely want to head into UEFI/BIOS and make sure your laptop is booting from the first NVMe. After that, back up your files from the second NVMe and wipe any partitions using Disk Management or the command prompt. Just use the command 'diskpart' instead of fdisk if you're using CMD, and check the commands with 'diskpart /help'.
