Rufus, installation Windows in UEFI NTFS

Rufus, installation Windows in UEFI NTFS: The following description makes it easy to create a bootable installation system on a USB flash drive with Freeware Rufus program.


The Windows 10 is larger than 4 GB and can not be installed on the FAT32 file system, even if the "Secure Boot" option in the BIOS is disabled. As a matter of fact, the FAT32 file system is older than the new NTFS today replaced by many security features, starting from safe backup support, to full file encryption. The Universal Extensible Firmware Interface (UEFI) provides a safe boot to the system, which means that the boot process will be in accordance with Microsoft's strict rules that prevent drivers from being loaded without a digital signature. If "Secure Boot" is not disabled in the BIOS, setup was unable to create a new system partition, and Windows cannot be installed, only on the FAT32 file system, so that the benefits of the NTFS file system can not be effectively used.
