システム、BIOS、ECのインストールにUSBドライブを使用した場合の障害解決方法？

Updated with November 12, 2024

Using a USB drive for installation is a common method; whether for installing an operating system, updating the BIOS, or the EC, it is convenient and not limited by the existing system. However, due to certain incorrect settings, this method may not work properly. Below, the causes of failure and their solutions are introduced.

1. The U disk boot file is missing

1. Generally, when creating a USB installation package, it must contain an EFI file, which is the boot file. If it is missing, attempting to boot from the USB drive may result in a black screen followed by an exit from the USB boot program, or it may prevent access to the USB boot program altogether.

2. The installation files are misplaced

1. Typically, multiple files are used for installation and should all be placed in the same folder after downloading. Simply copying the entire file package into the USB drive directory without proper extraction may also prevent the installation program from starting.

3. USB disk format error

1. Different files require different installation programs on the USB drive, and therefore the USB format requirements also vary. If you find that the format does not meet the requirements, you can change the format attributes by formatting the USB drive.
   1. Install BIOS&EC: The USB disk must be in FAT32 format

2. Installation system: The U disk must be in エヌティーエフエス format, and the name of the U disk must also be changed to ウインペ.

When this screen appears when installing the system, it means that you need to change the name of the USB disk to “ウインペ“

4. Secure Boot is not turned off

1. If you see the prompt shown above when selecting USB boot, it indicates that you need to change the Secure Boot option in the machine’s BIOS.

If you modify the BIOS options, remember to press F4 to save the changes, or the modifications will be ineffective.

5. Wrong boot sequence

1. Insert the prepared USB drive, and when the computer shuts down and restarts, press F7 to select the boot device. There will usually be multiple options; simply choose the USB drive you inserted.
   • The default first option is usually the hard drive with the installed operating system. If you choose it, the system will load from that drive.
   • The second and third options are usually the inserted USB drives. Choosing one of them will load the USB installation program, allowing you to start installing the operating system, BIOS, or EC.

6. USB port not recognized properly

1. Try inserting the USB drive into different USB ports. On some older devices, USB 3.0 ports may not recognize the boot device correctly. Try using a USB 2.0 port instead.

7.  Using the wrong installation tool

1. Currently, USB Flash-type installation files, such as those for the System, BIOS, and EC, are only supported for installation via USB drives. Using other devices, like external hard drives, will result in installation failure. In the image below, an external hard drive is used for system installation: although it enters the USB installation program, it gets stuck on the installation screen, and the progress bar at the bottom pauses.

As long as the installation hasn’t started, the files on the SSD won’t be deleted. On this screen, simply click the “X” in the upper right corner to restart the computer.
