How to Replace Ubuntu with Windows 10 Using USB🔥

Windows 10 was preinstalled as the default operating system on my computer. I accidentally erased the Windows operating system from my primary drive and replaced it with Ubuntu Linux. I'm unable to undo it and reinstall Windows 10 on that drive. I want to install Windows 10 on the Ubuntu-containing drive and erase Ubuntu via a USB, but how can I do that?

To replace Ubuntu with Windows 10 via a USB on your computer, you need to format the hard drive (your primary hard drive) to remove the installed Ubuntu OS and perform a clean installation of Windows 10. It is worth noting that installing a fresh copy of Windows 10 will erase data and programs on your PC.

Here are some things you should know about this:

1️⃣You need to prepare a USB flash drive with at least 8GB of space and a disk partition with 20 - 50GB of storage space to install Windows 10.

2️⃣Once you download an ISO image of Windows 10 from Microsoft to create a bootable USB or use EaseUS OS2Go to create one.

3️⃣Boot from the bootable USB drive to install Windows 10.

There are the detailed steps you need to follow to do that:

Step 1. Back up your data with free backup software - EaseUS Todo Backup.
Step 2. Create a Windows 10 bootable USB using a Windows bootable USB creator, like EaseUS OS2Go.
Step 3. Connect the bootable USB to your PC and boot it.
Step 4. Open the Boot Device to select the bootable media.
Step 5. Choose the disk partition and the Windows 10 version you want to install.
Step 6. A message with "This partition is not NTFS and has an unknown type" may appear.
Step 7. You will have the choice of "unlocated space."
Step 8. Press new and input the values for the new partitions' sizes in MB.
Step 9. Make the partition you want, choose one, and then proceed with the Windows 10 installation.

When it comes to making a bootable USB, it is recommended to use a professional bootable USB creator - EaseUS OS2Go. It can help you create Windows bootable media without downloading the ISO file from Microsoft's official website.

If you clean install Windows 10, all of the data, including applications and files you installed on Ubuntu, will be lost. Therefore, remember to create a backup of your data before installing Windows 10.
