Dual boot W10 with a second W10?

A friend was given a computer that's running Windows 10 Enterprise N.
The system runs but not 100%. One problem is that System Restore is damaged, so I can't back it up.
But there are numerous other little glitches so I plan to set up a fresh W10 Professional running alongside Enterprise.
Once the new version is complete with her files, emails, docs and games transferred, I'll delete Enterprise.

Her system drive is a 250GB SSD, but there's not a lot of space for the additional system so I've added a PCIe card with a new, empty 500GB SSD, on which I'll install W10 Pro.

It's a while since I've done anything as complicated as a dual-boot so I'm a little rusty. Any advice would be much appreciated

    Dual-booting Windows is straightforward but requires attention to partitioning and boot configurations. If you’re cautious and follow these steps, you should be able to set up a reliable dual-boot environment to transfer her data and then remove the old OS.

    Ensure the new 500GB SSD is properly installed and recognized by the system. Use Disk Management (search for it in the Windows search bar) to check its status. Note the drive letter assigned to it. You want to be absolutely sure the new drive is seen and ready.

    Ensure both OSes are installed using the same mode (UEFI or Legacy). Mixing modes can cause boot issues.
