Why delete or format the C drive containing the old operating system when installing Windows?

When installing Windows, we need to delete or format the drive containing old Windows and partitions of small size 1GB to: completely delete the old operating system, completely delete the files and old programs on drive C (files on drives other than drive C are not deleted).

Thus, after installing new Windows, our computer will have a new operating system, “clean”, not “disturbed” by junk software on old Windows (if any).

What is the difference between deleting and formatting the C drive containing the old Windows?

Each Windows when installed, in addition to the C drive, it also requires one or more small partitions (depending on the Windows installation standard is Legacy or UEFI) with a capacity of less than 1GB (these small partitions help the computer identify) disks and system software for booting Windows), with different Windows volumes and sizes of partitions under 1 GB.

Therefore, if you install a new Windows that is different from the version of Windows you are using, then after formatting and selecting the drive to install Windows, there may be a problem: redundant or missing drives with partitions smaller than 1GB, the size of partitions non-optimal area, .. This makes it easy to encounter errors after installing Windows, non-optimal performance (slow), ..

By deleting the drive containing old Windows and free partitions under 1GB, it completely overcome the above disadvantages because after deleting and selecting the drive to install Windows, the computer will automatically split the partitions with a number of and the size is appropriate for the new version of Windows you are installing.

Therefore, the best solution when installing new Windows is for you delete drive C containing the old OS and partitions less than 1GB in size.
