First of all your GRUB (Linux Bootloader) won't be deleted, just be overwritten by the Windows Bootloader
You can easily do it with a software called EasyBCD. Install Windows like you normally would and then install EasyBCD. Go to Add New Entry>Linux/BSD. Select GRUB2 and select the partition where you have your Linux installed (EasyBCD would have labelled it for you!). Rename your entry (You don't want NeoSmart Right?) to Ubuntu. Here's what it should look like!

Now you'd have both entries listed in Edit Boot Menu. Click on Save Settings. Now reboot your PC to find the Ubuntu option listed there. Select it to boot to Linux Bootloader
Hope this helps!
