Dualbooting RetroPie and Raspbian (while running VPN on Raspbian)

[Jundishi]

I currently have a Raspberry Pi 3 with RetroPie loaded onto it.

After the FCC Privacy rules vote yesterday, I would like to install a VPN on my Pi as well so I can run my traffic through there for encryption.

It looks like I can't install the VPN in Retropie OS so I would need to have the ability to dualboot both Raspbian and RetroPie.

From what I have been reading, the best way to do this would be to wipe my SD card and install BerryBoot then install Raspbian/Retropie via BerryBoot to give me the option of choosing the OS on boot up. From there I will be able to boot into Raspbian and install whatever VPN I choose.

Then I will have the ability to run the VPN on Raspbian and potentially boot into RetroPie to play games if I choose to.

Has anyone done something similar before?
Before I wipe all the configuration I already have, is there a better way of going about this??

Thanks for the help!

@Jundishi There is no such thing as RetroPie OS. RetroPie runs on Raspbian on the premade images. So anything that works on Raspbian will work on it.

@BuZz Thanks for the response

I haven't been able to find any mention of installing a VPN on RetroPie, is it even possible to do?

If I am understanding you correctly, then I should be able to exit RetroPie into Raspbian install the VPN on there?

Then once I turn on the Pi I will just need to exit RetroPie and enable the VPN and then go back into RetroPie??

I am a bit confused of the interaction.

Would it just be easier to install BerryBoot?

@Jundishi installing VPN on the retropie image is exactly the same as doing it on Raspbian. There are a selection of openvpn tutorials for Raspbian on the net. You can enable the vpn on boot for RetroPie via /etc/rc.local or via /opt/retropie/configs/all/autostart.sh

@BuZz Thanks for all the info.

I am pretty new to Linux but I think I should be okay with the VPN portion of it by following a guide.

As for enabling VPN on boot for RetroPie, that should be as simple correct? Just SSH into the Pi and edit the settings there?

Sorry for the dumb questions!
