How to Install Windows 11 from USB Flash Drive on a New PC Build

Installing Windows 11 on a fresh custom PC build is a straightforward process when following these essential steps: Step 1: Prepare the Media. On an existing computer, download the official Windows 11 Media Creation Tool from Microsoft and flash it onto an 8GB+ USB flash drive. Step 2: Configure Motherboard BIOS. Insert the USB drive into your new PC's motherboard rear I/O panel, power on, and tap Delete or F2 to enter BIOS. Ensure TPM 2.0 and Secure Boot are enabled in Security settings. Step 3: Boot Installation. Set the USB drive as Primary Boot Option and save changes. Step 4: SSD Partitioning. Select Custom Installation, highlight your unallocated NVMe M.2 SSD, and click Next to allow Windows to create required system partitions automatically. Step 5: Post-Install Setup. Once on the desktop, install your motherboard chipset drivers and graphics card drivers directly from official manufacturer websites.
