How to Install Windows 11 from USB on a System with BIOS
Instead of the conventional BIOS, modern computers employ the UEFI interface. BIOS is still used by many older computers and some specific devices. Here is a step-by-step tutorial on how to install Windows 11 on a system that has a BIOS.

Preparation of the Bootable USB Flash Drive
- Using Suitable Software:
- Download and install RUFUS.
- Start RUFUS and select your USB stick.
- In the “Partition scheme” section, choose “MBR” and as target system “BIOS or UEFI-CSM“.
- Load the Windows 11 ISO image using the “Select” option.
- Click “Start” to create the bootable USB stick.
Install from BIOS
- BIOS access:
- Restart your computer.
- During the boot process, repeatedly press the appropriate key (usually F2, F10, F12 or DEL) to enter the BIOS.
- Configuring Boot Options:
- In the BIOS, navigate to the “Boot” or “Startup” section.
- Make sure “USB Drive” or “USB Device” is set as the first boot option.
- Save changes and exit BIOS.
- Startup and Installation:
- With the USB stick inserted, the computer should boot from it.
- Follow the onscreen instructions to proceed with installing Windows 11.
- During the installation, you may get some warnings about the Windows 11 system requirements. If you have already prepared your USB to bypass these requirements (such as TPM or Secure Boot), you can proceed with the installation.
How to Install Windows 11 from USB Without Requirements
Windows 11 introduced a number of new hardware requirements that weren’t present in previous versions of Windows. In this guide, we will show you how to bypass these system checks and install Windows 11 from USB even on unsupported hardware.You must be aware, before moving forward, that ignoring the prerequisites could lead to Windows 11 compatibility problems or inferior performance.

How to Install Windows 11 from USB Without Meeting CPU Requirements
The system requirements for Windows 11 have been thoroughly set out by Microsoft, with an emphasis on specific CPU specs. Many users with older or unofficially supported CPUs may want to try the new OS. Here’s how to set up Windows 11 without having a compatible CPU. It’s important to keep in mind that installing Windows 11 on an incompatible CPU may result in poor performance and potential compatibility issues.

Prepare the USB stick using one of the procedures found in this article.
- Bypass CPU Control:
- On the USB stick, access the Sources folder.
- Locate the appraiserres.dll file and rename it (e.g. appraiserres.old). This file is responsible for checking hardware during installation.
- Download a modified version of appraiserres.dll with CPU checking turned off. You can find modified versions on dedicated community forums.
- Copy the modified version of the appraiserres.dll file to the sources folder of your USB stick.
- Startup and Installation:
- Insert the USB stick into the computer where you want to install Windows 11 and restart.
- During the reboot, select the option to boot from the USB stick (usually by pressing a key like F12 or ESC).
- Once booted from the USB, go through the installation process as usual, ignoring the CPU compatibility warnings.
- Post-Installation Configuration:
- Once the installation is complete, be sure to check for and install all available updates, especially those related to drivers, to ensure maximum compatibility and performance.
- It’s also a good idea to disable automatic Windows updates, as future updates may reintroduce compatibility checks or cause other issues with unsupported CPUs.
How to Install Windows 11 from USB Without Secure Boot Requirements
Secure Boot is a security feature offered by many modern UEFI motherboards, which prevents unsigned software or software that has a signature that is not recognized by the system from booting. Secure Boot was one of the key criteria for Windows 11 when it was first released, however not all systems can handle it, and some users might need to turn it off for particular reasons and requirements. Here’s how to install Windows 11 from USB without Secure Boot. If you decide to bypass Secure Boot, you could expose your system to potential threats, since the tool was designed to protect your system against rootkits and other threats that start before your operating system.
After preparing the USB stick with the Windows 11 ISO, you will need to follow these steps step by step:
Changing UEFI/BIOS Settings:
- Turn on the computer and, during the boot phase, press the specific key (usually it is F2, F10, DEL or ESC, varies according to the motherboard) to access the UEFI/BIOS settings.
- Browse through the options until you find startup or security settings.
- Look for an option called “Secure Boot” and disable it.
- While in the BIOS, also make sure the boot mode is set to “UEFI” and not “Legacy” or “CSM”.
- Save changes and exit BIOS.
Windows 11 installation:
- With the USB stick inserted, restart your system.
- During the reboot, select the option to boot from the USB stick.
- Follow the onscreen instructions to install Windows 11, ignoring any Secure Boot warnings.
Post-Installation:
- Once Windows 11 has been installed, we recommend that you install a good antivirus software and keep your system up to date, as disabling Secure Boot could expose your system to more vulnerabilities.
How to Install Windows 11 from USB Without TPM
Trusted Platform Module (TPM) is a piece of hardware used for cryptographic operations. One of the requirements of Windows 11 is the presence of TPM 2.0. Not all computers have it, especially older ones. This guide will show you how to install Windows 11 without meeting the TPM requirement.
Prepare Bootable USB Device and Edit Setup Files:
- Prepare Bootable USB Device and Edit Setup Files:
- Plug the USB stick into your computer.
- Browse to the Sources directory.
- Look for the file named install.wim or install.esd. The presence of either one depends on the source of the ISO.
- Use a tool like “DISM“ to mount the install.wim or install.esd file.
- Once mounted, find the appraiser.dll file and rename it (e.g. appraiser.bak). This file is responsible for checking hardware requirements.
- After that, unmount the image and copy it back to the USB stick.
- Windows 11 installation:
- Plug the USB stick into the computer you want to install Windows 11 on.
- Restart your computer and boot from the USB (usually by pressing F12, F10 or ESC, but depends on your motherboard).
- Begin the installation process by following the onscreen instructions. Because you modified the requirements control file, you shouldn’t get TPM related messages.
- Configurations After Installation:
- Once the installation is complete, proceed with the initial setup of Windows 11. Some features that depend on the TPM may not be available or work differently.
The TPM is used to ensure the security and proper functioning of many Windows features. If you decide to bypass this requirement, be mindful of the security of your data and consider adding additional safeguards.
