Can You Reinstall Windows 10 Without Losing Data from Other Drives

Can I do a fresh install of windows without losing data on my other drives?

As illustrated in this post from Reddit, if your current Windows 10 is bugged or slow, or your Windows 10 is installed on a small-capacity hard drive, you may need to reinstall Windows or replace the current hard drive with a larger one. However, a question arises for this issue: Will you lose data on other drives when reinstalling Windows or clean installing Windows?

The answer is NO. Fresh/clean install only deletes data from the drive you install on and nothing else to other drives. To illustrate further, it only deletes data from the partition you're installing Windows. If you have multiple partitions on the hard drive, all but one are safe.

You won't lose anything if the hard drive you plan to install Windows on is brand new. If you want to be 100% safe and secure, you can disconnect all other drives, install Windows, and reconnect other drives. You can also create a backup of your data on other drives before reinstalling Windows 10.

To this end, you can use professional free backup software, EaseUS Todo Backup, to help you create a backup of your hard drives. Once you have a backup, you can restore it anytime when needed.

Install Windows 10 on New Hard Drive via Cloning (No Data Loss)

Cloning can also help you install Windows on a new hard drive, and compared with a clean installation, it has many advantages: cloning can help you install Windows 10/11 on a hard drive in just several simple clicks, and it can help you transfer data from one SSD to another without losing data or reinstalling Windows from scratch.

To clone a hard drive in Windows 11/10/8/7, you must utilize professional disk clone software because Windows does not have preinstalled cloning settings. So, here comes a question: how to look for a reliable and efficient cloning tool for Windows PCs?

EaseUS Disk Copy is such a cloning tool that helps you migrate Windows 11/10 to a new hard drive without losing anything. It can help clone a hard drive and transfer boot drive to another drive with just 4 simple clicks.

In addition, it can let you create a WinPE bootable disk to boot your PC if there are boot issues. It has advanced sector-by-sector clone technology, which allows you to copy a hard drive bit for bit. If the target disk is brand new, it can directly migrate Windows OS to it. Here is how to use it to clone your Windows 10 to a new hard drive:

Prior Notice:

  • The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
  • All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

select the source disk and click next

Step 2. Choose the other disk as the destination disk.

select the destination disk

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout". 

click ok when a warning message appears
  • "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
  • "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
  • "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 4. Click "Proceed" to officially execute the task.
