Figure 4-43
Disk partitioning screen
These partitions are as follows:
±
Partition1 [FAT]: EFI System Partition
±
Partition2 [Reserved]: Microsoft Reserved Partition (both disks)
Do not attempt to install the operating system into the first two partitions. Instead,
use the unpartitioned space on the disk to create the data partition. The internal
disk is recommended if you have both internal and external disks.
The sizes of the ESP and the MSR partition are calculated according to the rules
described in “EFI System Partition” on page 33 and “Microsoft Reserved
Partition” on page 137, respectively.
Continue to the formatting screen. There is now an option to quick format (see
Figure 4-44 on page 144).
Tip:
Do not remove or resize the ESP and MSR partitions after they are
created. The ESP partition appears as
Partition1 [FAT]
and MSR partition
as
Partition2 [Unknown]
in the Disk partitioning menu during text-mode
setup.
