Make a boot U disk: Use Rufus to write Ubuntu ISO to at least 8GB U disk; 3. BIOS settings: Restart and enter the BIOS (usually press F2, Del or Esc), turn off SecureBoot, and set the U disk as the first boot item; 4.

The minimum hardware requirements of Windows 11 mainly include five aspects: 1. The processor must be from the sixth-generation Intel or Ryzen starting point or above, supports 64-bit, dual-core and above, the main frequency is not less than 1GHz, and is on the Microsoft support list; 2. At least 4GB of memory, but 8GB or higher is recommended to ensure smooth use; 3. At least 64GB of storage space, the system itself occupies about 25~30GB, and it is recommended to use SSD; 4. The TPM2.0 security module must be supported and enabled, many motherboards did not meet this condition before 2016; 5. Some users try to bypass the restricted installation may cause driver or update problems, and ordinary users do not recommend this.
