I think you are talking about doing some "partitioning", this is easy when you have Windows installed and do a "install along side" known as dual booting. Kind of more challenging doing it the other way around as Windows does not recognize the file systems Ubuntu uses by default known as ext2 or ext4 (not sure of Lubuntu defaults as it is either or).

You would have to use an application called gparted to create a separate ntfs partition for Windows to install on and then edit the grub2 boot loader to handle the boot process for Windows.

Honestly if you are not experienced with this and I would recommend backing up your files anyway I would do a fresh install of Windows 10 and then install Lubuntu. In the installer for Lubuntu there is a option to install along side Windows which will handle your partitioning for you and when complete and reboot grub2 each time will ask whether you want to boot into Windows or Lubuntu.

If you are looking for a good way to backup then use the "Backup" utility which I believe is installed on all Ubuntu flavors, if it is not on Lubuntu then run this command.

sudo apt install deja-dup

Then you will have the backup utility installed.
 
Use Gparted or Fdisk from a disk or usb and shrink the Lubuntu main partition size down.
Next, install Windows on that partition.
Then, download the free copy of EasyBCD and use that to install the GRUB bootloader.

Or, install PLoP to let you boot from a specific disk partition, boot from the existing GRUB partition, and then in Lubuntu run
Code:
$ sudo update-grub > ~/log.txt

If you have any issues, you can post the contents of log.txt to see what went wrong.

Tbh I would go with @DMGrier. Just nuke the hard disk and install windows, THEN install Unix over it. Ensure you shrink the main partition (Windows) using either diskmgmt.msc or diskpart.exe (GUI vs CLI) on WINDOWS. Ubuntu may mess up the Windows partition otherwise.
