How to set the boot partition of a computer

1. Insert the USB flash drive with integrated software into the USB interface of the computer, and then start the computer. When English appears on the screen, press the prompt button above to enter the BIOS. For example, a notebook usually presses the F2 key of the keyboard, and then chooses to start from a USB flash drive.

2. Change the hard disk mode: after entering the PE desktop, click the partition tool indicated by the arrow in the figure to enter the software home page.

3. Then you will see the size of the information capacity on the computer hard disk. If it is a computer without a system or a new hard disk, it will be gray, and if it has partitions, it will be orange.

4. Then click the option of software hard disk, select the mode of converting to GUID, click OK after selection, and the hard disk will be automatically formatted.

5. Click Save to change the hard disk mode and take effect. This action will erase all files on your computer. So be careful, and back up the data before operation. Whether it is a new hard disk or an old hard disk with a system, you must turn to hard disk mode to create an EFI partition.
