1Using UltraISO software to write the hard disk image to make an installation disk
1.1 Tool materials
UltraISO (Floppy Disk Link): The ultraiso tool can be used to make a U disk boot disk and download the latest version of UltraISO (Floppy Disk Link).
Image file: ubuntu-18.04.1-desktop-amd64.iso One
U disk (above 4G)
Note:
Before making a boot disk, make sure to back up the data, because all the previous files will be formatted; pay attention to the size of the image file, be sure The image cannot be larger than the USB flash drive.
1.2 Method steps

(2) Then select our U disk
(3) Then click Start->Write to hard disk image
. There are two writing methods: zip and hdd. Generally, we choose hdd or hdd+. After selecting the writing method, format first. After formatting, click Write to wait for writing That's it.
2 Install the Ubuntu operating system
(1) Set to boot using
U disk to boot. Insert the prepared U disk boot disk into the computer where the operating system needs to be installed, and then restart or boot. At the beginning of the computer restart or boot, press F12 or escape key to enter the BIOS system settings. The startup item is USB.
U disk boot, the machine is turned on by default. When the machine starts, the startup options are automatically loaded.

Please change
to mkusb for linux; use Win32DiskImager for
windows
http://sourceforge.net/projects/win32diskimager/files/latest/download
win32diskimager-1.0.0-install.exe
