I’m not sure I ask the right question, simply because I’m not very tech savvy but this is kind of an important thing for me (maybe for someone else too) which would bring a lot of peace of mind. So thank you in advance to everyone replying here.
I’m currently having a home PC running an OS other than Linux, unfortunately. The reason being that I need some proprietary software for my job, which is not available on Linux.
So I thought I’d buy a SATA power switch and connect three hard drives via it:
1 - the proprietary OS
2 - PureOS as my main OS
3 - this one I wanna leave for any kind of testing, and stuff, it’s just awesome knowing that you have a spare HDD waiting for you to experiment on it
note: Dual booting I consider as “not safe”, or at least not as safe as having a physical power switch.
So I’d have installed 2 or possibly 3 OSs but only activated one at a time. So my question would be if anything remains into any hardware components (other than the hard drive itself where the OS is installed) that could compromise the integrity of the other OS that we would switch to? Or if having such an infrastructure, all 3 OSs are 100% separated, and if activating them each at a time, in no way possible they could communicate, even indirectly?
note: the switch between one OS to another, would be done in such a way: 1- power off the PC, 2- toggle the OS switch and 3- start the PC.
