Can Bitlocker be used in a dual boot system with Windows on one drive, Linux on another?

If the new computer does not have a Trusted Platform Module, it should work just fine without any special setup procedures. Get the new computer, get Linux installed and dual boot working, then enable Bitlocker and encrypt the Windows drive.

I've got a similar configuration that works just fine, but I have separate partitions for Windows and Linux on the same drive.

It's still doable with a TPM, but it's not as straightforward.

Despite Spiderlucci's somewhat final comments :P, I've just set up a dual boot system with windows 10 using bitlocker (password encryption rather than tpm).

The steps I followed were:

• Remove bitlocker encryption via the bitlocker wizard
• Resize this partition from a ubuntu live cd (windows disk partition tool does support resizing, but was refusing to shrink my mostly empty 250G partition to much less than 170G)
• After this the bitlocker wizard/ GUI willfully claimed that it couldn't encrypt anything
• I worked around this by using the bde-manage.exe (https://technet.microsoft.com/en-gb/windows/dd361745) from an adminstrative cmd shell.

This is how I installed and managed to set up a dual boot of Linux (arch) and Windows 11.

1. In Windows:

• backup BitLocker keys (important!) you will need them later
• suspend BitLocker (it will stay off until next Windows boot)
• reboot to bios (f whatever key need to do or use advanced reboot from Windows)

2. In BIOS:

• turn off the secure boot
• boot from USB that you are going to install Linux from

3. Linux (you should be able to boot now) from USB

• install your distro on a separate partition and create a separate boot partition for it
• once installation has finished just reboot

4. Now you should see the grub menu and be able to boot Linux

• if you want to boot Windows from it you will need to provide BitLocker key
• you also should be able to boot Windows from BIOS boot menu (you still might need they BitLocker key)

Thats it!
