My windows 7 laptop had a motherboard issue but the removed HDD is still good. I want to create a bootable ISO-image of the windows-7 installation on this now external HDD that I can connect via USB to a Windows-11 laptop on which I have installed Microsoft windows Hyper-V virtual machine software. Hopefully this will allow me to run the programs that were on the windows 7 laptop using the virtual machine. These programs include over 10 years of tax software, 3-D Cad, etc. I have 64GB of RAM, a 1TB VME C drive, a new installed 1TB VME split into 500 GB D and E drives and a new installed 2TB SSD split into 1 TB F and G drives.
How do I go about creating the ISO-file from the installation that was in the windows 7 laptop? I could copy the installation over to one of the hard drives and make the ISO from there if that makes sense. If I moved it how would I do it so that the bootable ISO could then be created?
