Tutorial to Reinstall Windows without using a CD/DVD or USB drive.

Step 1. Run WinToHDD, then click the "Reinstall Windows" button.

Step 2. Please use the following guidelines to prepare your installation source.

• Installing from an ISO/WIM/ESD/SWM/VHD/VHDX File: Click the button, then click the button and select the ISO/WIM/ESD/SWM/VHD/VHDX file from the open dialog box.
• Installing from a DVD drive: Insert the Windows installation CD/DVD into your CD/DVD drive. Once the CD/DVD is being detected in Windows, then click button and select the CD/DVD drive in the drop-down list. If your CD/DVD drive is not correctly recognized by WinToHDD, you need to click the button for the program to recognize the CD/DVD drive.

Step 4. WinToHDD will automatically select the target boot partition and system partition from the partition list, and the selected partitions will be marked as red.

Tips:

1. The "Legacy" installation mode installs Windows directly into the boot partition on the drive, and the "VHD/VHDX" installation mode installs Windows on the VHD/VHDX file that is stored in the boot partition.
2. The "Enable support for 'Windows UEFI CA 2023'" option allows you to create a bootable medium that complies with Microsoft's UEFI CA 2023 secure signature standard. This enables it to pass Secure Boot verification on computers that only trust this new certificate. Therefore, please ensure that your computer's motherboard UEFI firmware is compatible with this standard.
3. The "Additional drivers" option allows us to inject drivers into the newly installed Windows, which is particularly important when we have to rely on hardware drivers to complete the Windows installation.
4. The "Bypass internet connection requirement" option allows us to bypass the Internet connection requirement when installing Windows 11.
5. The "Prevent automatic device encryption" option allows us to prevent automatic BitLocker device encryption when installing Windows 11.
6. If you want to encrypt boot partition using BitLocker, tick the "Enable BitLocker" check box and enter encryption password. You can also specify the encryption mode and encryption strength here.

Step 5. Click "Next". After clicking "Next", a pop-up will appear asking you if you want to build a WinPE image to continue. Click "Yes".

Step 6. After successfully builded the WinPE image, a window will pop up warning you that all data on the selected partition(s) will be destroyed before proceeding. If you are sure you want to proceed, please click 'Yes'.

Step 7. After clicking "Yes", WinToHDD will prompt you to reboot the computer, click "Yes" button to allow WinToHDD to reboot your computer.

Step 8. It takes some time to reinstall Windows. After successfully reinstalled restart the computer, Windows installation starts up and you have to complete all the installation steps.
