Does Formatting a Hard Drive Remove OS? Check Your Full Guide Here 2024 (2024)

Does Formatting Remove OS? Yes or No?

There are many reasons why you may wish to format a hard drive. Maybe your hard drive has corrupted data, and you have decided that reformatting the hard drive is the best way to get rid of it. Or maybe you just need to reinstall Windows 10 after a nasty malware infection attack. Whatever the reason, unfortunately formatting an OS hard drive will also erase any operating system installed on the computer, including Windows.

If your system drive is formatted, you'll have to reinstall Windows and then install your programs again. Even if you have a backup of your data or documents, the default format for external drives is NTFS, and restoring them to their previous state is a cumbersome process. After formatting, you cannot recover the original data from bad sectors on your hard drive.

Follow the guide below to know how to keep your Windows intact while formatting the hard disk!

Method 1. Format Hard Drive with EaseUS Partition Master
Method 2. Reset PC (Delete All Files and Reinstall Windows)
Method 3. Refresh PC (Keep Personal Files and Reinstall Windows)

How to Format a Hard Drive Without Removing OS

You can format a hard drive without deleting Windows using these methods:

Using Third-Party Software: Even though Windows has its own built-in Disk Management software, it still cannot compete with third-party partition managers. With an advanced and well organized interface, EaseUS Partition Master for Windows is a comprehensive disk management package for common users and IT engineers.

Reset your PC: Resetting your PC deletes everything you have on the computer, but doesn't change any of your personal settings. It doesn't affect the files you've saved in SkyDrive, and any OEM or additional apps that came preinstalled with the PC will still be available after resetting the computer. Also, all the files and documents stored on other partitions will not be deleted.

Refresh your PC: Tired of your dull Windows laptop? You can refresh it to reinstall Windows and keep your personal files and settings. Refresh keeps your preinstalled apps on the device, including Mail, Calendar, Maps, Music, and Photos, as well as any apps you’ve downloaded from the Microsoft Store.

Manual File deletion: The truth is, manually deleting files and folders from Windows is unsafe. It affects the functionality of your system, and if you are a novice user, you shouldn’t consider this.
