Welcome to the Community,
if I understand you correctly you are looking into converting the existing Win7 PC into a virtual machine!?
In this case you may use vCenter Converter: P2V-Converter für virtuelle Maschinen | VMware to do the job. Once done install VMware Tools within the guest VM (from the Workstation menu). VMware Workstation will automatically use the correct VMware Tools version based on the guest OS selection.
At this point in time my notebook only has one Harddrive with Win7
I think about to put in a second Harddrive with Win10 as primary OS
and then, from this new Installation Win10, create / use the
'old' Win7 as a VMWare under / from the Win10 System.
Ok, do I understand it correctly, its more simple to
1. create and save a Win7 Image by using the converter tool from within the Win7
2. install the new OS Win10 and install VM Workstation on this Win10 OS
3. install the Win7-Image ( saved from #1 ) as VM into the VM Workstation on Win10
thats right ?
Yes, that's basically how you'd usually do this.
- optional: backup the Win7 installation (using e.g. Acronis, etc.) if you are going to overwrite the current disk
- create a VM by using the converter tool from within the Win7, and save it on e.g. an external disk
- install the new OS Win10 and install VM Workstation on this Win10 OS (Note: you will need to disable Hyper-V on the Win10 installation)
- copy the Win7-VM's folder ( saved from #1 ) to the Win10 disk, and add it to the VMware Workstation inventory
