It is recommended that home or office users be divided into 2 to 3 zones: system disk (60 to 100GB for disk C), data disk (remaining space for disk D), optional backup/tool ??disk (approximately 50GB for disk E), dual systems require additional partitions. During installation, operate the partition on the "Custom Installation" page, and be careful to delete the old system partition to avoid confusion.

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.
