Hello I recently did a dual boot with fedora on my computer. So I disabled bitlocker for a moment but now all information about bitlocker just disappeared and Im not able to enable it again. Second question : do I really need it ?

Sorry for bad english
Thanks

Did you suspend BitLocker before installing Fedora? Or did you turn it off? If you turn it off, it it permanently removes the encryption from your Windows volume. But you should be able to set it up again, instructions are here: BitLocker Drive Encryption | Microsoft Support

Whether you need it or not depends on your situation. For a laptop that you take out of your house, you should definitely use BitLocker (and/or Linux full disk encryption) as it will help protect your personal data if your laptop gets lost or stolen. But if it’s a stationary desktop PC that doesn’t leave your house, then maybe you don’t need it as much.

I haven’t tested this lately on Fedora, but in the past I had issues with BitLocker and dual boot with Ubuntu: Booting Linux would invalidate the BitLocker key and trigger a recovery process. Not sure if this issue has been fixed as I haven’t tested it lately.

I turn it off it removed the encryption. But I have windows family and I guess its the problem, when I search for bitlocker in start menu nothing appeared the setting option aren’t there like bitlock never existed lol

Ah, ok. For Windows Home edition, you do not have access to the BitLocker feature. But there is a similar feature called Device Encryption: Device Encryption in Windows | Microsoft Support

Yes but before I set my dualboot all the bitlocker settings where there. And there is no “device encryption menu”

Why? In order to shrink the windows partition and setup dual boot?
Windows can shrink encrypted bitlocker partitions.
Then all you need to do is booting a fedora live iso and install into the free, available unassigned space.

Maybe it’s In windows security?
It should be possible to enable bitlocker/device-security via cli with manage-bde
IIRC there are several steps.

  1. enable encryption
  2. add protector(s)

don’t forget to write down or copy the recovery key(s)

Maybe it’s one of these reasons, as per the site:

Why isn’t Device Encryption available?

Here are the steps to determine why Device Encryption might not be available:

  1. From Start WindowsLogo type System Information, right-click System Information in the list of results, then select Run as administrator
  2. In the System Summary - Item’s list, look for the value of Automatic Device Encryption Support or Device Encryption Support
    The value describes the support status of Device Encryption:
  • Meets prerequisites: Device Encryption is available on your device
  • TPM is not usable: your device doesn’t have a Trusted Platform Module (TPM), or the TPM isn’t enabled in the BIOS or in the UEFI
  • WinRE is not configured: your device doesn’t have Windows Recovery Environment configured
  • PCR7 binding is not supported: Secure Boot is disabled in the BIOS/UEFI, or you have peripherals connected to your device during boot (like specialized network interfaces, docking stations, or external graphic card)

manage-bde donc work my “windows versions is not supported” thats why but I could do it before setting up the dual boot

It does work for sure on a WIn10 Home system with a local account. System doesn’t have any MS account.
This is not a win support forum but maybe check whether the system has finished decrypting the volume(s).

No.

It could be useful if you want to forget your password and lock your data permanently though.
