Tips
When creating a partition, Windows OS creates the
following partitions at the
top of hard disk drive.
Recovery Partition: 300MB
EFI System Partition (ESP): 100MB *1
Microsoft Reserved Partition (MSR): 128MB *2
528MB is allocated for these three partitions out of the specified partition size.
For example, when 61,440MB
is specified for partition size, the area available
free area is calculated as follows:
61,440MB – (300MB + 100MB + 128MB) = 60,912MB
Microsoft Reserved Partition (MSR)
*2
(128MB)
Recovery Partition
(300MB)
EFI
System Partition (ESP) *1
(100MB)
*1 May be 260MB in size depending on hard disk drive type.
*2 MSR is not displayed on Disk Management.

Using BitLocker
If using BitLocker, note the following.
Be sure to keep the recovery password secure. Do not keep it near a server running
BitLocker.
To reinstall the operating system into a partition that is encrypted with BitLocker, delete the
BitLocker-encrypted partition prior to reinstallation.
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
— Change of BIOS setting
— Initialization of trusted platform module (TPM) *
* Depending on your system, it may not be supported.
Refer to the document about hardware.
