Hi,
I am wondering about one point. I assumed that in the most likely scenario I would install OpenSUSE as the main system and Windows in a virtual machine.
Thanks to this, I would use the computer as before, starting Windows if necessary.
But when buying a used computer, as suggested here, I would most often have Windows installed (often in the Pro version).
In this situation, the option with a virtual machine becomes more difficult for at least two reasons:
- technical - how to get the system image from the recovery partition?
- legal - if I understand the information from Dell support correctly - 1 computer = 1 system installation; so Windows can be installed either on disk or in a virtual machine.
Forgive these trivial questions, but the last Windows system that I worked with with administrator privileges was Win XP (then only Linux privately, professionally - Windows without root privileges).
What would you do in this case, assuming you paid for the Windows license with your computer?
- Option with virtual machine, download Windows from Microsoft website and register in virtual machine with original product key (which I suppose I will get with computer)? What about the Recovery partition - is it justified to keep it (e.g. for later resale?)? Will it work?
- Dual boot - it seems to be the simplest but the least elegant option. I assumed that I would use Windows sporadically (for iPhone syncing with iTunes and Garmin eTrex). But perhaps Windows Pro should be used for other purposes?
In such a situation, keeping my existing HDD with data, I would have a difficult access due to the file system - ext4 and encryption of some partitions.
Besides, working more on Windows, I would have to run an SMB and DLNA file server on it, and the files are on ext4 partitions.
Yes, there is an option to transfer data to the Windows partition when replacing the disks with new ones, but I would not like to increase the cost of buying a computer with the cost of new disks.
- Setting Windows as the root system, OpenSUSE in a virtual machine. Is it possible to clone a host computer (OpenSUSE) to a virtual machine (OpenSUSE), perform a snapshot and then run a snapshot in Windows?
Which of these ideas makes the most sense to you? I know that it is best to verify it in practice, but before spending money, it is worth thinking twice 
I emphasize that at my age, the war of systems does not matter to me anymore, but I care about obtaining certain functionalities and comfortable use.
Last question - is the antivirus program “must have” in Windows?
Thank you and best regards!
