Dual booting with Win 10 Pro and Win 7 Pro

I'll be receiving a new computer with Win 10 Pro as my computer w/ Windows 7 Pro crashed. I'd like to take the hard drive with Windows 7 Pro and install it into the new one to have dual booting. Any problem doing that and what steps are needed? Thank
you.

How do I get the key for win 10 pro?

Hi,

I upgraded from win 10 home edition to win 10 pro. I had to reformat my computer with the factory image restore. It installed the win 10 but I did not have key to upgrade to pro. I have the following information from my Microsoft account. How do I get the
key for win 10 pro?

Here is my computer info where the win 10 pro got upgraded.

• DESKTOP-JP9JK4V
• Dell Inc. XPS 8900
  • Serial #: 3R8F082

Thanks!
