Although it is mentioned everywhere that the system partition should be at least 350 MB, mine even though being 100 MB, there was no prompt to expand the drive to 350 MB and process straight away skipped to step 12. Was there any change 350 MB min requirement?
Hello Andcha,

Not that I'm aware of. Please post a screenshot showing all of your Disk Management to see if it may explain what happened. :)

Interesting, Microsoft either changed it, or this was a fluke. It'll be interesting to see if others see this as well with only a 100 MB System Reserved partition instead of 350 MB.

That too 55 MB is free out of 100.
Microsoft FAQ was last updated in October 2013, so maybe latest update has changed this requirement.
My only concern is that nothing goes wrong with my system in future because of this.

It should be fine, but I would recommend to keep a copy of the BitLocker recovery key and startup key in a safe place just in case you may need them in the future.

Shawn - I just wanna say thanks ! Super professional tutorial, you covered everything. I did lot of h/w s/w through yrs but I'm always wary of doing stuff like this which could potentially lock you out. The only thing I had to read on was TPM maintenance, and I decide to leave it "un-owned" (Im guessing factory initialized to make it easier for the users), hope I'm not going to regret it : )
And man are you meticulous :) I thought I was, and I mean in a good way

A tiny question -but don't feel obliged to answer : )
What are the things to be aware of once running a bitlocker? I've seen a lot of it like "it may be if you're running a bitlocker" but I'm trying to find some walk-through article link or something.
E.g. h/w setup, dual-booting, I can't boot from USB then into Win (it needs from HDD), Win 8 to Win 8.1 or upgrades (require turning it off temp) - anything else that pops into mind, or some link you may have handy?

And thanks again for all the effort

P.S. just to add my details. I did a TPM Bitlocker on Win8 Pro, I used gpedit to init, and "let Bitlocker" handle the stuff (i.e. no pass - but relying on the user login pass protection). I had 8.1 but factory refreshed to 8 - taking my time on the clean system for a while : )

Hello Gaga, and welcome to Eight Forums. :)

The main thing about BitLocker is to make sure you keep a backup of the recovery key since you will not be able to recover the drive without it if you should ever need to.

You can boot from a USB with BitLocker enabled. It may be Secure Boot or Fast Boot enabled in your UEFI firmware blocking you from booting from a USB. Temporarily disabling them will allow you to.

Hi Shawn,

Been a while since someone posted on this topic, but I am keen on using Bitlocker and giving it a go for its simplicity as an encryption tool.

My question is, if I encrypt, say a Thumb drive or external HDD using Bitlocker on Windows 10, would I then be able to go on to another computer that is running Windows 7/8.1 with Bitlocker on it and use that/those encrypted drives. Logic tells me yes, but always good to hear others answers and confirmations.

Hello doyoc, and welcome to Eight Forums. :)

I'm not sure what you mean. Just to verify, are you saying that the USB will no longer unlock the OS drive at startup?

Please provide more details.

Hi. The reg file just makes the options available in the manage bitlocker control panel settings. For example, if I import the reg file I'll still have option to encrypt with password and not usb key?

Hello jmsync, :)

That's correct, the .reg files are only for turning on BitLocker with or with a TPM. You would still be able to setup BitLocker how you want with a USB or password.
