Here is how to create a Windows 11/10 bootable USB with EaseUS OS2Go.
Step 1. Install EaseUS OS2Go on your Windows computer, it will display your system drive's used space. Plug in a USB drive that is larger than the system drive used space. Choose the target USB drive and click Next to continue.
Step 2. EaseUS OS2Go will notify you that the following operation would delete all data on your drive. Make sure that you have backed up all the important data. Click the Continue button to proceed.
Step 3. Adjust disk layout. The default disk layout on the target drive will be exactly the same as the resource drive. You could also edit the layout according to your needs. Tick the option there if you're using a Solid State Drive as the Windows bootable drive. Next, click Proceed.
Step 4. Then EaseUS OS2Go will start to create the portable USB drive. It usually takes a while depending on your OS and Network condition. When the progress reaches 100%, the USB drive should be bootable now.
Step 5. Insert the portable Windows USB and start your computer. Press the required key (F2, DEL, F10...) to access BIOS. Choose to boot from the USB disk.
Note: Please make sure that the boot mode (UEFI or Legacy) of the portable USB and your target computer are the same, otherwise you may not be able to boot.
If you want to install a second version of Windows on the same drive as the first, there must be enough space. If you're low on storage, this may be challenging. For example, dual booting Windows 10 with 11 ideally requires about 20-25GB (however, we usually recommend at least 50-100GB of free storage space).
You can perform the following steps to create a new partition using Disk Management Tool.
Step 1. Hold down the Windows + R keys to open the Run dialogue box. Then type diskmgmt.msc and press Enter.
Step 2. You will see a list of the partitions on your hard drive. First, select the primary partition, usually C drive, then right-click it and select Shrink Volume.
Step 3. In the box near Enter the amount of space you want to shrink in MB, input a number, then click the Shrink.
- To create a 25GB partition on your hard drive, enter 25000. Doing this lets you change the partition and make the room needed to set up Windows 10 or 11.
Wait for the process to finish, and you will get an unallocated volume.
Before installing another Windows on your computer, you must prepare your computer for installation. Here is how to prepare your PC. Take Windows 10 for example.
Step 1. Turn off Fast Boot
You can disable Windows' Fast Boot by doing the steps shown below.
- In the Windows search bar, type Control Panel and then open it.

- Tap Choose what the power button does.
- Hit Change settings that are currently unavailable.
- Ensure that the bottom box labeled "Turn on fast startup (Recommended)" is not checked. Then click Save Changes.
Step 2. Enter BIOS on your computer
To install a second operating system, the BIOS will require some changes. Each computer brand and model has a unique way of accessing the BIOS. You may enter the BIOS on some computers by pressing one of the function keys (such as F1, F2, F9, or F12), Esc, or Delete while your computer is booting up. The steps listed below can also be used to reboot the BIOS in Windows.
- Click the Windows 10 Start menu.
- Click the Power icon.
- Hold down Shift and click Restart.
- Click Troubleshoot.
- Click Advanced Options: UEFI Firmware Settings
- Click Restart.
Step 3. Disable Secure Boot
The BIOS menu varies from one computer to another. To access the BIOS menu, use your keyboard's arrow keys. The Security, Boot, or Authentication menus are typically where you may access Secure Boot. Find Secure Boot and change its status to "Disabled".
Step 4. Change the boot order to boot from a USB
Typically, this can be located in the Boot menu. Find the boot order menu, and change it such that a USB drive boots up first.
Step 5. Save settings
After making the appropriate BIOS system changes, find the option to save your settings. Then, use the BIOS save and exit option to save and restart your computer.
Now, let us come to the last part, how to install the second OS on your computer. Follow the instructions below to install Windows step by step:
Step 1. Insert the bootable USB drive into your computer.
Step 2. You should restart your computer if it is on. If not, turn on your computer by pressing the power button, which will cause it to start from the USB drive.
Step 3. You can see the setup program for the operating system if your computer successfully boots from the bootable USB drive.
