Optimize hard disk to reinstall Windows

“Hi, recently I found my Windows 7 computer runs rather slow so that I plan to make a reinstallation. Well, do I just need to reinstall Windows to its original place or should I perform some extra operations”. If you are not very familiar with reinstallation, you may ask such a kind of questions. Actually, we highly suggest optimizing hard disk before reinstallation so as to get best performance.

How to Optimize Hard Disk to Reinstall Windows
1.Wipe and delete boot partition and system partition to clean old data completely.
Further reading: boot partition is the partition saving Windows system files, and it is always the C drive. System partition is the partition storing Windows boot files, and it is called system reserved partition or efi system partition.
As we know, both deleting and formatting just operate file allocation table (FAT) or master file tale (MFT) and will not erase data thoroughly. As a result, some data may still exist with keeping invisible even after we are installing Windows. However, wiping partition will erase every sector of a partition so that no data will be left. Then, delete both partitions to release unallocated space. Tip: MiniTool Partition Wizard Bootable CD is highly recommended to do these operations.

2.Install Windows via Windows installation disc.
It is believed that most people know steps to install Windows, so here we directly skip to the screen which asks where do you want to install Windows. Here, please choose the unallocated space released by boot partition and system partition to install Windows, and then perform the remaining operations by following instructions.

Note: if you are not allowed to install Windows even after deleting system partition and boot partition, try wiping the entire hard disk, which may work for you. In addition, if you want to create a system reserved partition, please wipe the entire hard disk, too.

After successful installation, Windows would run smoothly. In addition, if you are running Windows on SSD, pay attention to the 4K alignment issue since it will influence system running speed to a large extent. And to align partition(s) can make 4K alignment realized. MiniTool Partition Wizard can help do this with ease:
