If using BitLocker, note the following.
•
Be sure to keep the recovery password secure. Do not keep it near a server running BitLocker.
Important If the recovery password is not entered, the OS cannot be
started, and the content of the partition encrypted by BitLocker
cannot be referenced any more.
The recovery password might be required at startup of the OS
after the following:
– Replacement of motherboard
Initialization of trusted platform module (TPM)
Change of BIOS setting
•
To reinstall the operating system into a partition that is encrypted with BitLocker, delete the
BitLocker-encrypted partition prior to reinstallation.
•
Microsoft releases software updates for BitLocker encryption. If using BitLocker, it is important
that you read through the information provided by Microsoft. Also read through the checklist
published by Microsoft.

 If the OS installation media contains Service Pack 1, you need not apply the service pack
again.
 You can install the Service Pack on the server. When the Service Pack is not attached to
your system, prepare it by yourself.
License authentication might be required, depending on the installation of Windows.
For details, see Chapter 1 (3.14 License Authentication).
Note • Activate within 30 days following installation.
• A Virtual Product Key is used when installing in a virtual
environment. It is not used when directly installing an operating
system to a physical server.
Do not compress the root directory and the Windows directory.
Tips The Windows Server 2008 R2 directory is labeled as "Windows".
If you compress the root directory and the Windows directory, operational stability cannot be
ensured because the Windows File Protection (WFP) may replace an unassigned driver with a
signed driver.
