I'm trying to switch my computer's boot drive from an old drive to a new one. I've cloned the old drive to a partition on the new M.2 drive, but the BIOS isn't allowing me to select the new drive as the boot location. The new drive has been in the system for about a year and has data on it, so I know the system recognizes it. I have some photos I'll share in the comments if they help!

It sounds like your new drive isn't set up correctly as a boot drive. You might need to check its settings or the way it was cloned; sometimes cloning doesn't include the boot sector. If you can, try a different cloning tool or consider doing a clean install of your OS after backing up your data.

What if it's not a USB drive? Does that change anything?
