BitLocker Keys
More details on my OneNote page. They are needed to authenticate changes to the BIOS and without them BIOS locks you out. Locating the BitLocker Keys was a unexpected challenge. This is what I did.
- Google search on "BitLocker recovery Enter the recovery key for this drive" took me here
- Windows 10 Find my BitLocker Recovery Key
- Selected In your Azure Active Directory account. For work PCs where you sign in with an Azure Active Directory account, to get your recovery key, see the device info for your Microsoft Azure account. This took me to:
- UP Profile Page
- With my UP account and password I went here. window azure
- In my Profile Page I selected in the "Device and Activity" section "Get BitLockerKeys"
Missteps
Things I Backed Out Of
- Boot from the Linux Boot USB
- Didn't create a proper USB boot install - corrected with Rufus on Windows
- Install Alongside Windows 10 option did not show
- Disable hibernate in command tool - couldn't turn of Fast Start
- Don't Partition disk ahead of time - do a Shrink only
Things I Thought of Trying
- I was going to decrypt the Windows C: file system. However none of the command line or windows tools were available, for example, Disable-BitLocker. I was going to install them but got install to work before this
- I though about using GPT in Regus because it works with larger disks and more partitions. I got things to work before I got to this.
Partition
Reference
Create Partition
- Open Computer Management by selecting the Start button. The select Control Panel > System and Security > Administrative Tools, and then double-click Computer Management.
- In the left pane, under Storage, select Disk Management.
- Right-click an unallocated region on your hard disk, and then select New Simple Volume.
- In the New Simple Volume Wizard, select Next.
- Enter the size of the volume you want to create in megabytes (MB) or accept the maximum default size, and then select Next.
- Accept the default drive letter or choose a different drive letter to identify the partition, and then select Next.
- In the Format Partition dialog box, do one of the following:
- If you don't want to format the volume right now, select Do not format this volume, and then select Next.

Because I wasn't getting Fast Boot disable I reversed the following - See No install beside See also how to prepare for dual boot. See also install along side Windows. Didn't hellp
From Andrew Gilligan (12/17/17) "One thing of note, regardless of single or multiple disk booting strategies, you may need to disable hibernate on the Windows side, it expects a warm boot to return to Windows, when it goes to Linux instead it causes headaches on the next boot of Windows."
- Click Start, and then type cmd in the Start Search box.
- In the search results list, right-click Command Prompt, and then click Run as Administrator.
