Graphic tutorial on creating a USB boot disk using UltraISO

USB boot disks are usually used, because you cannot reinstall the system at ordinary times. If the boot disc is not started, making a USB boot disk is a very feasible method, I remember this situation when I last reinstalled the system. After downloading a inexplicably compressed package, decompress the package and run the package --> install it. On my desktop, add a shortcut icon and right-click the icon, in the right-click option, there are only two options: "attribute" and "create shortcut". They cannot be deleted at all, and I tampered with the IE homepage, and it is useless to modify the information in the registry, in a rage, reinstall the system. My personality is quite urgent. I directly went downstairs to purchase a CD. After I came back, I made a dial --> reload. But don't want to, the disc was carved out, but you have to find another method. After I burned the disc, I tried to create a USB boot disk to reinstall the system.

To create a usb boot disk, first go to the BIOS page of your computer and view the BOOT items on the "BOOT" tab to reinstall the system in several ways. Take my notebook as an example. The USB boot items provided in the notebook provide the following first boot items: "usb hdd", "usb fdd", "usb key", and "usb odd. The following describes the startup methods. "Usb hdd" simulates a USB interface as a hard disk and serves as the first boot item. "usb fdd" simulates a USB interface as a soft drive, "usb key" simulates the USB interface into a usb key digital certificate form as the first startup Item. Knowing the form of these first startup items, you need to understand the methods for simulating these first startup items. There are a lot of software in this category. I will illustrate it with my example, I use UltraISO (UltraISO download) and the version is UltraISO Premium 9.35. The first step is to open UltraISO and display the system interface:

In the lower-left corner of the interface, you can see the "local directory". Next, open the directory where the system image is located, find the system image file, and double-click it to open it, for example:

Find the "Start" menu on the interface, and find the "Write hard disk image" option in the drop-down menu. Select this option. The following interface is displayed:

We can see that the path of the system image we just selected is displayed on the right of the "Image File". First, select the "format" button to format the USB flash disk. After formatting, note: Open the drop-down menu of "Write method,

At this time, we can see a total of four forms, which have to be selected based on the first Bios boot item in your computer, based on the first boot item in your computer, what are the boot items in the boot item can choose which Boot Mode, generally can choose "USB-HDD" Hard Disk form write, because the hard disk form is more popular, if your computer's BIOS does not have the "USB-HDD" option, choose another option that exists in your computer's Bios options. After these steps are completed, you can select the "write" button to write the USB flash disk. After the writing is complete, enter the computer Bios to set the first startup Item, on the "Boot" tab, select the one you just selected in "Write method. Press "F10" to save, and the system reinstallation interface is displayed. So far, the preparation process of the USB boot disk has been completed, and it is quite practical. This is my experience.
