I have a desktop computer with Windows 8.1 that does not have a TPM Chip. This PC has a second fixed hard drive with 1tb of space and I use this hard drive primarily to store all my OneDrive Files/Folders. I use Bitlocker to encrypt my fixed hard drive for protection, and I use Microsoft Account to log into the computer.

The issue is that when I restart my computer, I have to manually unlock my bitlockered drive (as my OS drive is not encrypted), but there is no way I have been able to find to stop OneDrive starting automatically. This causes OneDrive to freak out at every start and then the app takes hours of "Setting up" and "Checking for changes" to go through my 150K+ files that I store on OneDrive.

I have trying switching to Local Account but OneDrive goes completely missing. 

Has anyone else have this issue and have they managed to resolve this? I think it is a very obvious use case. All I want to do is, protect my import files on local PC and Sync it with OneDrive.

Any suggestions to fix this issue?

This TechNet article tells that if you want to unlock your fixed drive automatically, the operating system drive has to be also protected by Bitlocker.

Then your fixed drive will also be automatically unlocked and the OneDrive application will start normally.

And what if I don't want to encrypt the OS partition? What can I do to "delay" the startup of onedrive?

You can setup onedrive to sync only at night or at specific times, or alternatively you can just disable the startup and start it manually when you're ready to sync.

how do you do that?
