I have a Dell M3800 Laptop with a 512GB SSD.

I want to install 2 instances of Windows 8.1 - the user would choose at boot up - and each would be protected by bit locker.

is this possible?

I was interested and found out by trying.
You'll find it hard to believe, but it "just works".
Steps to reproduce, to do it just like me (I did it inside a hyper-v machine, so no tpm):
-add a hard drive with 40 GB, boot setup, create a 20 GB partition, install win8.1
-boot setup again, install a second win8.1 into another 20 GB partition.
-boot one of those, encrypt it, reboot
-when starting, select the OS you just encrypted and confirm that your password works, then restart
-boot the other OS by selecting F11 at the Bitlocker prompt, encrypt it using a different password of course, reboot. Done, both are bootable, one is the default option, the other is reachable via F11, Bitlocker works for both without any issues!

Yes.. I tried it earlier.. Worked like a area

I used diskpart to remove the volume name of the os partition for the other instance.

I also used bcdedit to change the os names in the boot menu so it was easier to identify what instance you are booting into

Thanks for testing it out
