Prevent Windows OS to access other partitions

cn flag

I have three partitions of the SSD:

  1. Ubuntu with all my work
  2. partition for videos/photos
  3. (here I want to install Windows 10 OS)

I would like that Windows 10 OS is "completely constrained" to the third partition. That it has no access to partitions 1 and 2, for security reasons.

How to do that?

Unless you encrypt partitions 1 and 2, you cannot. Even if they are not mounted (or whatever terminology is used by Windows), Windows should at least see them and/or know that they're there. What you seem to be asking for is to someone make Windows not even know the other two partitions exist. I don't believe you can.

Thanks @Ray, actually I'm ok with windows knowing the partitions are there (or even know the partitions' meta-data like size), I just need to prevent it to be able to access (read) the content.

Unless you do encryption, I don't think you can. A normal user has permission to mount a partition in Windows, I think. That isn't the case with Linux/Ubuntu -- system administrator's access is required. So, this is more of a problem of Windows allowing normal users to mount than Ubuntu/Linux allowing it to mount. Perhaps you can create a user in Windows with a lower access level and see if it can be used to mount. I think your problem is more of an issue for Windows than Linux. I don't suggest you use encryption, because that opens up other potential problems.

"I would like that Windows 10 OS is "completely constrained" to the third partition. That it has no access to partitions 1 and 2, for security reasons." Impossible. Even with encrypyion you can delete the partition :-) If you do not want Windows to touch Ubuntu do not put the on the same machine. And this is a windows problem... not Ubuntu... we take security serious and require a mandatory admin with admin password for these kind of actions ;-)

You can encrypt each one. LUKS for Linux and bitlocker for windows.

Thank you. Will this slow down the regular reading of media on partition 2., and my regular work on partition 1.?

I don't think so. You will have to unlock them each time you want to access them though.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
