To install Ubuntu, you must first burn the ISO file to a CD disc. For this job, you need a CD/DVD burner that works. This document describes how to do this in Windows, Mac OS X, Ubuntu, and Kubuntu. If the CD write fails, try lowering the write speed.
In Windows 95/98/me/2000/xp/server 2003/vista
1, verify the ISO file (highly recommended, but not necessary).
2, download and install Hashtab, a free hash (hash) validator, can make you very easy to verify the file.
3. Right-click the ISO image file and select Properties.
4, select "File hashes" and compare the computed hash (hash) value to the same as listed below:
Edgy Eft
Dapper
5, burn ISO image, download and install ImgBurn, a free mirror burning program.
6, insert a blank CD-ROM, if there is a dialog box pop-up please choose do nothing (no action) or cancel (undo).
7. Right-click the ISO image file you downloaded and select Burn with ImgBurn (use ImgBurn burn).
8, click on the "Write Disc" button, and then wait for the disc to burn complete.
