How to Install Windows 11 on Unsupported Hardware: Bypass TPM 2.0 and Secure Boot Restrictions (2025 Guide) Announcements Buyer Guide Comprehensive Tips Occasion Product Review Q&A Tutorials Preparation: Download Required Tools Before starting the installation process, you need to prepare two essential components. First, download the latest Windows 11 ISO file from the official Microsoft website. Make sure to select the correct edition and language for your needs. Second, you’ll need a reliable USB flash drive with at least 8 GB of storage capacity. Remember that this drive will be formatted during the process, so back up any important data beforehand. The key tool for bypassing hardware restrictions is Rufus, a free and open-source utility for creating bootable USB drives. Download Rufus 4.1 or a later version from the Rufus official website. This version includes critical updates that enable TPM 2.0 and Secure Boot bypass functionality for Windows 11 installations. Create Installation Media with Rufus Launch Rufus and insert your USB flash drive into the computer. The software should automatically detect the drive. If not, use the “Device” dropdown menu to select it manually. Next, click on the “Select” button and navigate to the location where you saved the Windows 11 ISO file. In the “Partition scheme” section, choose “GPT” if your system uses UEFI, or “MBR” for legacy BIOS. For most modern computers, GPT is recommended. Under “Target system,” select “UEFI (non-CSM)” to ensure compatibility with newer hardware configurations. [Verified] The critical step for bypassing restrictions is enabling the “Skip TPM check” and “Skip Secure Boot check” options in the “Advanced drive properties” section. These options are only available in Rufus 4.1 and later versions. Double-check that these boxes are checked before proceeding. Click “Start” to begin creating the bootable drive. A warning message will appear, notifying you that all data on the USB drive will be destroyed. Confirm this action and wait for the process to complete, which typically takes 5-10 minutes depending on your system and USB drive speed. System Installation: Bypass TPM and Secure Boot Errors With your bootable USB drive ready, restart your computer and enter the BIOS/UEFI setup. The method for accessing BIOS varies by manufacturer, but common keys include F2, F12, Delete, or Esc pressed during startup. Once in the BIOS, disable Secure Boot if it’s enabled, and ensure that USB boot is prioritized in the boot order. Save your changes and exit the BIOS. Your computer should now boot from the USB drive and launch the Windows 11 installation process. You’ll first see the Windows Setup screen, where you can select your language, time and currency format, and keyboard input method. Click “Next” and then “Install now” to proceed. When prompted for a product key, you can either enter it now or select “I don’t have a product key” to activate later. Choose the edition of Windows 11 you want to install and accept the license terms. At this point, you might encounter the “This PC can’t run Windows 11” error message, which indicates that your computer doesn’t meet the official hardware requirements. This is where the Rufus bypass comes into play. Don’t panic—this is expected behavior. Simply click “OK” and then “Back” to return to the previous screen. Select the “Custom: Install Windows only (advanced)” option. You’ll now see a list of your computer’s drives and partitions. Choose the partition where you want to install Windows 11, or select “Unallocated Space” if you’re setting up a new drive. Select custom installation option Click “Next” to begin the installation. The setup process will copy files, install features, and update components. Your computer will restart several times during this process, which is normal. Post-Installation Setup and Configuration After the final restart, you’ll be guided through the Windows 11 out-of-box experience. First, select your region and keyboard layout. You can add a second keyboard layout if needed, or skip this step for now. Select your region Choose keyboard layout Next, you’ll encounter the network setup screen. It’s recommended to disconnect from the internet at this point by selecting “I don’t have internet” in the bottom-left corner. This bypasses the Microsoft account requirement and allows you to create a local account, which is particularly useful for unsupported hardware configurations. Select the offline setup option. Select “Continue with limited setup” and then enter your desired username for the local account. You can create a password later if you wish. Review the privacy settings and customize them according to your preferences. Windows will then finalize your settings and take you to the desktop.

BIOS RAID Setup: A Comprehensive Configuration Guide for 2025 Announcements Buyer Guide Comprehensive Tips Occasion Product Review Q&A Tutorials When your server suddenly crashes due to a hard drive failure, have you ever wondered if there’s a way to protect your data while maintaining performance? The answer lies in BIOS RAID configuration—a critical skill for every IT professional in 2025. This guide will walk you through the entire process of setting up RAID through BIOS, from hardware preparation to performance verification, with real-world test data and expert insights to ensure you get it right the first time. Prerequisites for BIOS RAID Configuration Before diving into the setup process, you need to ensure your system meets these essential requirements: Motherboard Compatibility: Must support RAID configuration (check your motherboard manual or visit the manufacturer’s website for specifications). Storage Devices: Minimum 2 SATA SSD/HDD (including MSATA, M.2 SATA, or 2.5-inch SATA drives). For optimal performance, use drives with identical capacity and speed. Data Backup: All existing data on the drives will be erased during RAID setup. According to Backblaze’s 2025 Data Loss Report, 68% of RAID configuration failures result from inadequate backup procedures. UEFI Mode: After setup, the operating system must be installed in UEFI mode—legacy BIOS mode is not supported for RAID arrays. Step-by-Step BIOS RAID Setup Process Accessing BIOS Setup Utility Press the Del key rapidly after pressing the computer’s power button to enter BIOS Setup. In the BIOS, select Chipset > PCH-IO Configuration > SATA and RTS Configuration > Set the “SATA Mode Selection” to “Intel RST Premium with Intel Optane System Acceleration.” > Press the Esc key on the keyboard to exit the current page. Finally, select “Save & Exit.” 3. After restarting, quickly press the Del key to enter the BIOS. Select “Intel(R) Rapid Storage Technology” > “Create RAID Volume” > RAID level, such as RAID 0, RAID 1, or RAID 5 (Note: RAID requires at least three SATA hard drives for setup). In this tutorial, we will use RAID 0 as an example, but you can choose according to your needs. Select the disks by using the spacebar and then click “Create Volume.” Conclusion: Making the Right RAID Choice for Your Needs BIOS RAID configuration remains a cornerstone of data storage management in 2025, offering a perfect balance of performance and protection when implemented correctly. Remember: 4.Introduction to RAID0, RAID1, and RAID5:RAID0 is a simple, non-redundant data striping technology. In reality, it is not a true RAID because it does not provide any form of redundancy. RAID 0 combines multiple disks into a larger storage space by striping the data across them. Data is distributed and accessed independently across all disks, allowing for parallel I/O operations and efficient utilization of the bus bandwidth. As RAID 0 does not require data parity calculations, it offers the highest performance among all RAID levels. In theory, a RAID 0 consisting of n disks can achieve a read/write performance that is n times that of a single disk. However, actual performance gains are lower than the theoretical values due to limitations such as bus bandwidth.RAID 0 offers advantages such as low cost, high read/write performance, and 100% utilization of storage space. However, it does not provide data redundancy, meaning that if data becomes corrupted, it cannot be recovered. Therefore, RAID 0 is generally suitable for applications with strict performance requirements but lower demands for data security and reliability, such as video and audio storage, temporary data caching spaces, and similar scenarios.RAID 1, also known as mirroring, writes data identically to both the working disk and the mirror disk. It has a disk space utilization rate of 50%. RAID 1 may have a slight impact on response time during data writes, but it does not affect data read operations. RAID 1 provides optimal data protection, as in the event of a failure in the working disk, the system automatically retrieves data from the mirror disk without affecting user operations. The working principle is shown in the following figure.RAID 1 is the opposite of RAID 0. It aims to enhance data security by creating a complete mirror image of the data on two disks, resulting in improved security, simplified technology, and easier management. RAID 1 has complete fault tolerance capabilities but comes with higher implementation costs. RAID 1 is applied in scenarios that require high sequential read/write performance and prioritize data protection, such as protecting data in email systems.RAID 5 simultaneously stores data and parity information on the disks. Data blocks and their corresponding parity information are stored on different disks. When one disk fails, the system can reconstruct the lost data using the remaining data blocks and corresponding parity information from the same stripe. Like other RAID levels, the performance of RAID 5 is significantly impacted during data reconstruction.RAID 5 balances storage performance, data security, and storage costs. It can be seen as a compromise between RAID 0 and RAID 1, providing the best overall performance for data protection. RAID 5 can meet the storage requirements of most applications and is commonly used as a data protection solution in data centers. By following this guide and leveraging the included performance data, you’ll be able to configure a reliable RAID array that meets your specific needs while avoiding common pitfalls. As storage technology continues to evolve, staying current with BIOS RAID best practices will remain an essential skill for IT professionals worldwide.
