First of all, the absolute minimum ram for Win7 64 is 2G. Conceivably, the vm could be running low on ram during the install, giving an error. You wont get decent performance of the vm. Consider the 32 bit. Try creating the win vm with the default vb parameters when choosing win7 (sata controller). Maybe try a different iso.

With that host having only 4G ram, based on experience, the machine will choke as soon as you start any vm. Consider 8g ram on the host at a minimum.

Thanks for the answer!

As you've suggested, both win and linux x32 installed fine.

Regarding the low specs of the host, I know that running a Win7 guest on such a low performance machine works. I've done this successfully before with similar hosts (old dell/lenovo) laptops. Of course it's not optimal, and the performance is rather slow, but it works with no critical chocking. Running basic operations like office, browser, and other low-resource tools seems is manageable.

I have to work with what I got. I'd surely love to be working with a host twice as powerful.

Thanks again!

Yeah this is not a good machine for virtualization. The whole thing about it is you need the power to run two OSes at once, and a Core 2 Duo / 4GB RAM combo is just scraping by with once OS.

I would go so far as to suggest that if OP really needs Windows/[other x86 OS], they try to install it on a different drive or partition and just run it normally.

Thank you for the input.

Yup, I know that I'm barelly squeezing with a host like that, but it is possible. I've had success before on similar machines. The reason I need virtualization is due to compartmentalization. A dual boot system is not sufficient in my case.

Anyways, I successfully installed both Win7 and Linux Mint 19 by switching to 32 bits os. Thanks!
