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

Introduction

The Windows 10 install.wim file 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.

Quick tip: It is therefore recommended that you install the new Windows 10 system on each computer and on the UEFI mode on a modern NTFS file system.

Start

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. Since, the installation system file is more than 4 GB, in the Rufus program must be selected the NTFS file system instead of FAT32, and the "Secure Boot" option in the BIOS must be deactivated before installation. Proceed as follows:

That's what I did

1. - I downloaded the Rufus program (can be used without installation)
2. - I introduced one 8GB flash drive into the free USB port
3. - I started the Rufus program (the connected flash drive detects automatically)
4. - In the "Boot selection" entry line, on the right side of the window, I clicked on the SELECT button
5. - In Windows Explorer, I searched for the downloaded Windows 10 ISO file and then clicked on the Open button
6. - In the "Partition scheme" line, I chose GPT because I wanted to install the system in UEFI mode
7. - In the "Volume label" line, I entered the volume name (eg Windows 10)
8. - In the "File system" line, I selected the NTFS file system instead of FAT32
9. - I pressed the START button. Windows will display an error message "All data will be deleted from the flash drive". I clicked on OK
10. - Begin copying the ISO file
11. - Finally, appear a new warning window in which warns that, based on the selected options, before installing, it will be necessary to disable the "Secure Boot" option in Bios
12. - Ready. It didn't take longer than 4 minutes

More detailed

Download Rufus (can be used without installation). Insert a flash drive of at least 8GB into the free USB port.

Start the Rufus program (automatically detects the connected flash drive).

In the "Boot selection" entry line, on the right side of the window, click on the SELECT button.

In Windows Explorer, look for the downloaded Windows 10 ISO, and then click on Open.

In the "Partition scheme" line, choose GPT because the system installation will be in UEFI mode.

In the "Volume label" line, enter the volume name (eg Windows 10).

In the "File system" line for formatting, choose file system NTFS instead of FAT32.

Press the START button. A warning window appears that "All data will be erased from the flash drive". Click OK

Begin copying the ISO on flash drive. Finally another warning window appears that, based on the selected options, you need to disable the "Secure Boot" option in Bios before installing. Click the button CLOSE.

Ready. It did not take more than 4 minutes with copying for all.

Quick tip: If you are installing the system from the USB ready, you do not have to remove the flashdriv from the USB port.

In BIOS, you must disable the "Secure Boot" option when you restart the computer. ASUS, the Taiwan IT industry's the motherboard manufacturer, introduced unduly complicated security, making it harder to install the system in UEFI mode. Lenovo or Dell is simpler. The image below shows the ASUS BIOS motherboard where the option can be disabled.

Quick tip: If for some reason you are unable to install bootable Windows based on the above description in UEFI mode, read the description on the next page. Maybe this helps you Install in UEFI mode …

Attention: To avoid losing data, do not suddenly remove the flash memory from the USB port. The NTFS file system may disappear with the data on it, and you have to format USB flash drive, but formatting would erase all the data from USB flash drive. In the taskbar, next to the clock, at the bottom right, click on the up arrow, then right-click on the USB icon and select the "Safe device removal" link (or a similar entry) from the mouse menu.
