    Dual boot on different hard drives completely isolated from each other


    I have a configuration with 2 hard drives and I'd like to install Ubuntu and Windows 10- let's say- Ubuntu on hard drive C, Windows 10 on hard drive D. To prevent malwares from spreading from an OS to the other, I'd like to permanently disable ubuntu's hdd in Windows and windows' hdd in Ubuntu.

    Is all that possible? Does that configuration really prevent malware from attacking the other hdd?

    What I could contribute about this layout:

    Suppose that you have two separate Operating Systems (Windows & Ubuntu), and assuming that one of the operating systems grabs malware, such as spam / advertisements / apps that are spamware / etc, then it is very unlikely that this type of malware will spread to the other operating system, no matter where the other operating system is. It could even be on the same drive. Since this type of malware is very unlikely to support both operating system, then it will only infect one operating system. So you can have Windows & Ubuntu on the same drive, or different drives.

    YET, there is one condition about malware. Assuming this malware that you grab is a very terrible type of malware (not spam nor advertisements), and is some sort of Trojan or Virus or such, where a person can take control of your computer, then no matter what, everything that is currently connected to the computer may be at risk, depending on what the person wants to do with your data that this person has access to. They could be very harmful and lock all your files until you pay them money/etc, but it all depends. There are also some malware that could just erase everything that's on the computer.

    But there's nothing to worry about these malicious types of malware, unless you open an untusted link, or some sort of advertisement stating that your computer is at risk, call this number, etc. If you ever see some weird "unprofessional" message pop up on your screen, it's most likely an advertisement from your internet browser that popped up from some website, and you shouldn't be tricked by it. Just close those types of windows.

    Thanks for answer. Actually I think about viruses and other threats that could erase or modify files. Given that I'd use Ubuntu as test platform, it may happen.

    It's a very good solution for desktop pc. Unfortunately, I forgot to say that I'm talking about a notebook with 2 ssd.

    One good practice you can get into:

    I save all my personal files (music, documents, videos) on a different drive other than the main drive that has the operating system on it. If I download files that I may want to keep, I download it onto the main drive, go through what I want/need, then save it on the other drive. From time to time, I also back up all my documents / music / videos onto an external hard drive, which stays disconnected from the computer (and sits in the closet). That backup drive is only used when I backup my documents / music / etc from the 2nd drive that is currently connected to the computer.

    Maybe you can come up with a good idea by having those two drives with your layout of having those two different operating systems.

    Ideas:
    Two partitions on one drive; Windows & Ubuntu. Save all your documents on the other drive
    Windows on one drive, Ubuntu on the other drive. Save all your documents on the drive with Ubuntu, since it is very unlikely that your Ubuntu drive to get infected. Malware is usually targeting Windows.
    etc

    As long as the SSD/HDD is physically connected to the computer, a virus can get to it.

    Hiding Them


    You must hide them from each other.

    In Ubuntu, open gnome-disk-utility to hide Windows 10. In Ten, open Mini Tool Partition Wizard to hide Ubuntu.

    That's it!

    -In Disk: Addiional Partition Options>Edit Mount Options>Deselect User Session Interface For Windows Main Partition>Turn The Switch ON>Apply Change.
    -In Partition Wizard>Hide Ubuntu Main Partition.

    For the viruses, even if they do (must be made to do so), they rarely travel from one drive to the other or even when dual boot, because there aren't compatible with ext4, LVM or BTRF partition schemes. Cross talk does it, but hiding them help alot.

    This method removes them from File Explorer and from File Manager or Nautilus in Ubuntu.

    Lastly, surfing the web safely is your best protection. A more robust method is to lock the boot sequence, but you have to enter the BIOS to boot each time.

    All the best,

    I can't think of any virus or other malware that are compatible with Windows and Linux or can affect both !

    Thank you! Do you mean disabling hard drive in BIOS according to the OS I want to run?

    Disabling a drive in BIOS would be most secure (next to disconnecting it physically) but disabling access or visibility from other system should be good enough. In Linux you can just un-mount other drive(s).
