As you know, the requirements for Windows 11 installation include the need for your computer to support TPM 2.0 and Secure Boot. However, if your computer lacks these standards, you can still install Windows 11 using one of two methods: customize Windows 11 ISO files for installation on Legacy BIOS or intervene in the Windows Registry.

Method 1: Installing Windows 11 on Legacy BIOS by customizing Windows 11 ISO file
Firstly, for a successful installation of Windows 11 on Legacy BIOS by customizing the Windows 11 ISO file, ensure you meet the following conditions:
+ Windows 11 ISO file. Access the Windows 11 download link here (if not already obtained).
+ A computer running Windows 10 is the most suitable condition.
+ A USB with an empty capacity of 8GB to create a Windows 10 Bootable USB. Refer to the process of creating a Bootable USB here.
Once fully prepared, follow the instructions below to install Windows 11 on Legacy BIOS:
Step 1: Right-click on the Windows 11 ISO file and select Mount to open the file.
Step 2: Subsequently, click on file sources.
Step 3: Next, locate the install.wim file to copy.
Step 4: Connect the USB containing the pre-prepared Windows 10 file to your computer. Open USB in File Explorer, then find and open the source folder.
Step 5: Then, paste the copied install.wim file from step 3 into the sources folder on the USB.
Step 6: In the Replace or Skip Files alert window that appears, click Replace the file in the destination.
Step 7: After successfully replacing the install.wim file, you need to reboot your computer.
Step 8: Next, when the Boot device options window appears, choose to boot the system using the Bootable USB containing Windows 10.
Step 9: Finally, after the system successfully boots from the USB, you'll see the option to install Windows 11. Click and choose to install the Windows 11 version on your computer.
Method 2: Installing Windows 11 by intervening in the Windows Registry
Another workaround to bypass TPM 2.0 and Secure Boot requirements for Windows 11 installation is by modifying certain Registry settings during the installation on Legacy BIOS.
Essentially, this is a technique that doesn't impact any functionality of the computer, and this method can be applied to any PC device.
Step 1: Execute the following instructions to Install Windows 11 by intervening in the Windows Registry:
Step 2: Press the Windows + R key combination to open the Run dialog. Then type regedit into the text input box, and press Enter to launch the Registry Editor.
Step 3: In the Registry Editor window, navigate to the path: Computer\HKEY_LOCAL_MACHINE\SYSTEM\Setup
Step 4: Right-click on the empty space in the right-hand pane. In the opened menu, choose New => Key.
Step 4: Introduce a fresh Registry Key into the left table of the Registry Editor window; christen this new entry as Labconfig.
Step 5: Below the Labconfig file, right-click in the vacant space. From the menu that materializes, opt for New => DWORD (32-bit) Value.
Step 6: Rename that value to BypassTPMCheck. Then, reiterate step 5 to forge another DWORD (32-bit) Value, naming the value BypassSecureBootCheck.
Step 7: Following this, double-click on the BypassTPMCheck file to unveil the customization dialog, input a value of 1 for Value data, then hit OK.
Step 8: Repeat the process from Step 7 with the BypassSecureBootCheck file.
Step 9: Close the Registry Editor window and restart your computer to apply the changes.
Step 10: Finally, try running the prepared Windows 11 Preview ISO file and install Windows 11 without the need for TPM 2.0 and Secure Boot.
Above are two methods for readers to try installing Windows 11 when their computer lacks TPM 2.0 and Secure Boot support. One is through Legacy BIOS, and the other involves modifying the Registry to bypass the two Windows 11 installation conditions. Both methods have a high success rate; however, it's advisable to back up important data on your computer for the highest information security.
