What is the usual size for MBR boot partition

As we know, system reserved partition in Windows is also called boot partition. And the usual size for MBR boot partition is about 100MB in general situations. Nevertheless, most users have encountered the situation where boot partition is contained in system partition. What’s the reason? Next, we list 3 possible reasons:


1. Install Windows 7 by upgrading.
2. Hard disk has been partitioned before we install Windows.
3. Hard disk is partitioned via diskpart.exe in the process of installing Windows.


Well then, what is the usual size for MBR system partition when boot partition has been contained in system partition? In theory, 40 GB is recommended for 32 bit Windows operating system and 60GB for 64 bit Windows. Now, check whether your MBR system partition owns reasonable size. If not, resize MBR boot partition to get desired partition size.


How to Get the Usual Size for MBR Boot Partition


We have said users can resize partition to get reasonable boot partition size, but how to complete this operation? At this time, a professional partition manager is needed rather than system built-in disk management tool. Here, MiniTool Partition Wizard is highly recommended. Next, let’s use this tool to extend MBR boot partition.


Firstly, launch the partition manager to open its main interface:
Then, select the boot partition namely partition C and click the function “Extend Partition” in action panel.
Next, extend partition by taking free space from an existing partition or from an unallocated space and drag sliding button to decide how much free space to take. Here, we take 18GB free space from partition D. After clicking “OK” button, we can see the following interface:
Now, we can see the size of boot partition becomes 47.32GB from original 29.30GB. At this time, as long as users click “Apply” button, they can get the usual size for MBR boot partition.


If users’ MBR boot partition is not allocated with reasonable capacity, download MiniTool Partition Wizard to get desired size.
