How to extend boot partition/C partition in Windows 7

Updated on Dec 04, 2018 by Tracy King to Partition Master

When the boot partition or system C drive becomes low disk space, Windows 10/8/7 would run extremely slow on your computer. Then you'll need to add space to the C drive. Here you can use EaseUS Partition Master to extend boot partition/C partition in Windows 7/8/10 in a few simple steps.

The definition of boot partition

The disk partition that contains the Windows operating system files and its supporting files is called boot partition. By default, the Windows operating system files are in the WINDOWS folder, while WINDOWS\System32 folder contains supporting files.

The boot partition can be the same as system partition (usually referred to as C partition), but they can be on different partitions too, there is no requirement on this. Generally, there is only one system partition; while there will be one boot partition for each operating system under a dual-boot or multi-boot environment.

Need to extend boot partition/C partition

As computer technicians, we are always asked how to speed up Windows 7 computers and make it run faster, how to resize partition, especially extending boot partition without reboot to maximize computer performance or solve Windows 7/8/10 low disk space warning. Would you please tell me the safest way to extend boot partition/C partition without data loss?

While you can always use Windows 7 Disk Management, but there is no obvious improvement of Disk Management tool in Windows 7 compared with Vista, the limitations, especially that it cannot move partitions, make some advanced partition management operations in Windows 7 still need a third-party partitioning utility like EaseUS Partition Master.
