What version of VirtualBox? VirtualBox 6.1.x does not have an option to enable or disable hardware virtualization.

It does have an unrelated option to enable nested virtualization, but you've given me no reason to believe you should care about that. You don't need that to run any VMs on your host.

Virtualization on the host is enabled and disabled in the host BIOS, not in VirtualBox. It's a feature of your PC.

It does! I tried to run windows 7 and the installation crashed. I created another VM and the other one worked. Virtualization is enabled by default for me and on VBox it's enabled by default too, but i turned it off

Please show me a picture of the grayed out option.

And please tell me the VirtualBox version.

So you are referring to the "nested paging" setting?

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

Hardware virtualization is turned on, and is of course used by the VM since that is no longer optional in 6.1.x.

Trying to run Win7-64bit in only 1024MB of RAM and 1 core doesn't seem like a good idea, however doing much better will be hard since your Asus host is extremely limited - only 6GB RAM total, and Win10-64bit installed as the host OS.

You also have no Extension Pack installed, no Guest Additions, and you seem to be running the VM from drive H: which I hope is not a USB flash drive!

These choices will not give good performance.

That will be much slower, especially when booting up or doing updates.

If you have automatic updates enabled, Windows 7 will try to install hundreds of updates. That could take quite a while on a slow vm.
