Re: How To Disable Bitlocker In Windows 10 Using Cmd

If Bitlocker encryption is enabled, the storage location of the content present in the encrypted drive of the imaging computer cannot be identified. Hence, decrypting the contents of the bitlocker encrypted drive is essential for efficient imaging.
To disable bitlocker using command line, ensure that you have logged onto Admin user account to turn off bitlocker encryption. Follow the steps given below to turn off bitlocker encryption using Command Prompt.
You can ensure if the BitLocker encryption is removed by checking if the Bitlocker lock icon is removed in the particular drive and by accessing the particular drive. You can repeat the same steps to disable Bitllocker Encryption in other drives.
To disable Bitlocker encryption in Windows Powershell mode, Windows Power shell must be installed in your system. If not download & install proper Windows Powershell version from Microsoft website. Also check the Powershell System requirements before proceeding installation.
Note: If the partition with the operating system contains any automatic unlocking keys, the cmdlet to disable bitlocker encryption will not work. You can use the Clear-BitLockerAutoUnlock cmdlet in Powershell window to remove all automatic unlocking keys to disable BitLocker for the partition.
I just enabled and completed Bitlocker encryptoni on C: on a Win 10 Pro machine, remotely. I saved the bitlocker key file just in case. In order to maintain remote access over the long term, I want to ensure the computer does not prompt a user for any kind of key, I just need it to boot to Windows as normal. I'vec had users in the past, where BitLocker was on, be prompted by it at times, for no known reason. I really do not need the hassle, so I'm trying to determine how to be sure of this, yet can't.
Oh so do you mean that suspending or disabling might make those other 2 options available to toggle? That's logical I agree so I'll test that out, however my goal is to avoid enabling any features that result in users having to interact at boot time to allow booting to occur. It seems all of these 3 options in some way will ask a user to interact, which means, if I'm using remote access, I'll lock myself out by rebooting.
Now I suppose what I need to understand is why Bitlocker would have any reason to prompt a user on boot, be it triggered by an event, or periodic by design like after certain more intrusive Windows Updates perhaps. *shrug8
To turn off Bitlocker encryption on Windows 10 or 11, open the Control Panel, navigate to System and Security > Bitlocker Drive Encryption, and then click "Turn Off BitLocker." Windows will take some time to decrypt your drive.
Windows 10 and 11's BitLocker feature, for Professional and Enterprise editions, encrypts your drive to help keep your data secure. If you don't want this encryption for some reason, it's easy to disable BitLocker and decrypt your drive. We'll show you how to do that.
If you're concerned about privacy and security, know that removing BitLocker encryption makes your drive data more accessible in certain situations. For example, if you use a dual-boot PC, the other operating system can access the data stored on your drive if you've disabled BitLocker. Also, if your laptop gets stolen or you lose it, whoever has it can access the unencrypted data on your machine's drive.
If your concern is with remote hackers and thieves accessing your drive's data while you're connected to the internet, keep in mind that BitLocker doesn't protect against that; your data is already decrypted while you're using the machine. It's the job of your firewall, your antivirus software, and yourself as the user to protect you from online threats. A person or another operating system with physical access to your device will be your main concern if you choose to proceed.
Windows will now start decrypting the contents of your drive, which can take quite some time, especially if your drive has a lot of content on it. In the meantime, you can continue to work with your files as usual.
I then read up on BitLocker. I satisfied myself reading -to-use-bitlocker-on-drives-without-tpm/ and -and-bitlocker-on-a-mac-with-boot-camp/ that I could create a Bitlocker FDE Windows 10 partition and a FileVault FDE MacOS partition on the same drive, and did so. The problems started after this.
However if I plug in a USB keyboard and mouse (side note: ALWAYS keep one of those around for events such as these!) both built-in keyboard and trackpad function as expected and the MBP becomes usable.
Note that Apple's Boot Camp control panel on Windows 10 can see the FileVault encrypted MacOS partition, and I can type in the BitLocker password using the built-in keyboard when booting into Windows 10.
Unless BitLocker is unlocked, corresponding Windows drivers are no loaded. Plugging an external keyboard causes the drivers to be loaded, which allows the internal and external devices to work. There are other implications of external USB devices and Secure Boot.
After removing BitLocker FDE on the Windows partition I still don't have a [built-in] keyboard or trackpad until MacOS boots. As per the above, this makes FileVault inoperable (as I can't input a FileVault password) as well as any startup key combinations.
However this is not correct: Suspend Bitlocker before starting the Ubuntu installation and you will avoid the lengthy procedure of decrypting and re-encrypting the disk (which spoils your SSD/NVMe as well).
The EFI partition that comes with preinstalled Windows is rather small. Users who know the caveats of creating their own partition are smart enough to do it without this mentioned directly. Users who know a bit about partitioning but do not understand the full consequences should no tbe urged to forge ahead. Also, adding warnings about this-and-that for the borderline users does not belong here. It is better leave the instructions as simple as possible.
my experience doing this on one drive is that Windows tends to just take over the boot manager when you alter your device encryption configuration (as in, decrypt device then install ubuntu on dual boot then re-encrypt which requires you to set BIOS to load the windows boot manager first) - windows just goes ahead and removes your boot manager when you do that
I have just upgraded win10 to win11 and had the same issue as one commenter, that bitlocker was not activated but still blocking the install from a USB stick. I activated it, deactivated, and had to resart the computer twice.
THen I checked in Disk Manager and it was indeed no longer encrypted by BitLocker. I could then restart for the 5th time or so, and the install Ubuntu 20.0 from USB stick worked.
My new HP Pavilion came with bitlocker enabled. I would like to disable it but there is no option to do so in the Control Panel. I do see the option in Settings. Is there anything I have to do other than select turn it off?
I had to type each fedora update windows recovery key when booted to windows, but that might be just my hardware and Nvidia stuff and eventually it just lost boot option to fedora ending running WSL or VM setup and second laptop just fedora bare metal
from within windows use the disk manager to shrink the windows partition and allow space for the fedora install. This is especially critical since you are using bitlocker. The space freed up must remain unallocated.
boot the fedora installation media and do the install. Do NOT create an additional esp partition but allow fedora to automatically perform the partitioning and install. It is best to allow both OSes to share the existing esp partition.
(experienced users may define their own partitions but normally fedora does it quite well with the automatic install)
I do not use bitlocker so have no experience with the stated need to use the uefi boot menu to boot windows. Yes, grub is the default boot loader in fedora and it is installed automatically. When dual booting the grub menu should show each time you boot, which normally allows the user to select the kernel or OS to boot.
This depends upon your hardware and what drivers you use. If you do not install software that requires locally compiled kernel modules then secure boot may remain enabled. I think windows 11 probably uses secure boot by default (and may even require it). You may also sign the locally compiled modules which will allow them to load and also allow keeping secure boot enabled.
If you have a GPU such as nvidia and use the nvidia drivers or use virtualbox to run VMs, both have locally compiled kernel modules and require that either you disable secure boot to use unsigned modules, or create a local signing key and enroll it into the bios so the modules are signed when compiled and continue to use secure boot.
I use secure boot, and have installed nvidia drivers as well as virtualbox from the rpmfusion repo. There is a package named akmods that manages compiling and signing these modules for me.
Once the package akmods is installed there is a readme file /usr/share/doc/akmods/README.secureboot containing the instructions on how to create and enroll the key so modules may be automatically signed and will load with secure boot enabled.
This may be a result of using bitlocker. Is it possible to disable bitlocker without a full reinstall?
If not then it should be possible to copy off the data you desire to keep, then do a new install of windows without bitlocker and start over with the fedora install.
It has been many years since I worked with windows at that level. His info reminded me of what I used to do when windows was my main OS and had forgotten by now. Admin tasks done 15 or more years back tend to be forgotten.
Have only booted windows once in the last 6 months and that was only for update purposes. Since windows does the auto updates without asking for permission I did not want it updating when I happened to be travelling and on a slow or metered connection.
If you really do not need windows it seems that you might consider installing fedora on the drive, then use libvirt and virt-manager to create a VM of about 50 GB or so in size and install windows 10 into that VM so it would be available if needed. I guess that it might be possible to use win 11 in that manner but I have not tried that yet. Win 11 requires secure boot and TPM. libvirt does provide secure boot, but I have not tested the TPM capabilities.
