How to set up Bosch to emulate Win 7 x64 on Windows 7 x64?

Question

Virtualization

I downloaded bochs-2.6.7-win64, but I can't figure out the settings.
I didn't see any guides on the internet.
I do a similar task in VMware in 5 minutes, but then I got confused.
As a cd-rom image, I choose an image with win7x64.iso, I can’t create a hard disk. Cpu chose i7, RAM 2GB. Runs, gives out 2 messages, that the error is with the rum and the error of the hard drive. How to fix?
Maybe someone has already launched a virtual machine or someone has a ready-made image?
Help me please.
