Hi,

I will install Ubuntu 16 and windows 10 both 64 bit on virtualbox. We are using these as development/research environments.

I just want to learn about these options o virtualbox:

1- There is an option: "enable EFI". Is this option supports for UEFI ? Or it is just EFI 1.X version?

2- Which operating systems are supporting by "EFI" option? At least can you please tell me if Ubuntu 16.04 64 bit and windows 10 64 bit is supporting?

3- I know that SATA and IDE are alternative of each others. SATA is newer technology. Can I switch my drive (VDI or WDMK) to use SATA or IDE anytime I want? Or I should install the operating system again? I mean will I face driver problems?

Thanks in advance

EFI is mainly used for OSX guests. It is not as mature as the BIOS yet. It works, but it is not necessary to have it enabled. People have reported that it works with Win10 and Ubuntu 16.04.

You can switch between SATA and IDE as long as your operating system supports it. Ubuntu 16.04 and Win10 do, as far as I know. Mind you that you cannot switch controllers on the fly (yet). You have to remove the HD from the controller, remove the controller, add a different controller and re-add the HD.

I think you should stick to the defaults for these values selected by the OS template. There are good reasons why the defaults are what they are, and until you have the knowledge to contradict the dev expert who selected that setting, you should probably stick with it!
