Mainly, by partitioning your disk, you can separate your operating system from your data and thus when system corrupted, it can reduce the chances of your data becoming corrupted. For this reason, you can make partition after installation. Next, this passage will introduce how to make partition in Windows 7 after installation.

Step 2: Right-click on the partition you wish to resize and select the Shrink Volume option.
Step 3: Enter the size you wish to shrink your drive to in megabytes (1000 MB = 1GB). Then click on the Shrink button.
Note: You cannot shrink your volume greater than the amount indicated in the Size of available shrink space in MB section.
Step 4: You should now see a new unallocated partition in your Disk Management window. Right-click on the unallocated partition and select the New Simple Volume option. The New Simple Volume Wizard should pop up. lick on the Next button to continue. Enter the amount of memory you wish to allocate for your new partition and click on the Next button.

If you want another new partition, follow the same step. If your disk is MBR, sometimes, you may receive an error message: you cannot create a new volume in this allocated space because the disk already contains the maximum number of partitions.
MBR disk only supports 4 primary partitions or 3 primary partitions and 1 extended partition at most. In this case, you have to convert primary partition to logical partition.
