Hard drive data security when using two OS?

Question

Operating Systems

I want to put a couple of OS (Windows 10 + Linux) on one machine, divide one hard drive into two logical ones for them. Further the most interesting: I want that OS (both) could not read/change (format) a logical disk of other OS. About disk encryption using OS, I roughly understand that this will not allow another system to receive data, but the current OS can format this area. Is this true, or maybe there is a necessary functionality for managing access to the hard disk?

UPD (after reading the answers): the answers confirmed that data cannot be saved from destruction when using two OSes (from myself: and from LiveCD / USB too). Therefore, it is safer to use machines in single-user mode with backups.

Answer 1

No way. The system has full access to the disk, because it is mounted with such rights))

Answer 2

1) In Linux, disable mounting the partition with Windows.
2) Tadamm, nothing needs to be done in Windows, since Windows knows how not to mount ext-X out of the box

Next is the most interesting: I want the OS (both) to be unable to read / change (format)

This is not done by the OS, but by the user. If the user has crooked hands, then the software cannot protect partitions, since the user can stick a screwdriver into the disk ...

Answer 3

You just disable administrator / superuser rights on both OSes and that's it. A normal user will not be able to format / mount drives of another OS without installing additional drivers.

Answer 4

pick fstab in Linux and Disk Manager in Windows for what you have mounted automatically in this system, if the disks are not mounted, then there will be no access to them at the application level, and you don’t have to worry about the data
