Ubuntu在Internet上以CD镜像文件的形式发行。要从CD安装Ubuntu,你需要先把下载的ISO镜像文件刻录到CD上。这需要一个可用的CD或DVD刻录机,和一张80分钟(或700MB)的空CD。如果刻录失败了,尝试一下以较低的速度新刻录一张CD吧。CD检验检查页面描述了怎样校验刻录完成的光盘。如果重启之后你的光盘不能引导,请参考从CD引导页面。

获取Ubuntu页面上有这些ISO镜像文件的链接地址,还记录了其它的获取Ubuntu的方式。

关于CD和DVD刻录的一般信息,可以参考CD/DVD刻录页面。

MD5校验值

在刻录CD之前,值得推荐的是先校验一下这个ISO文件的MD5值。校验的步骤请参考如何校验MD5。请参考在 http://releases.ubuntu.com 你所使用的Ubuntu发行之下的MD5SUMS文件,以获得当前的官方Ubuntu镜像的MD5值(可选的,也可以从MD5SUMS.gpg文件得到PGP校验校验值),或者查看Ubuntu校验值页面。这可以保证ISO文件在下载过程没有被破坏,是100%完整的。

Windows

95 / 98 / ME / 2000 / XP / Server 2003 / Vista: Infra Recorder

  1. Download and install Infra Recorder, a free and open source image burning program.

  2. Insert a blank CD in the drive and select Do nothing or Cancel if an autorun dialog pops up.

  3. Open Infra Recorder and click the 'Write Image' button in the main screen.
    • Alternatively you can select the 'Actions' menu, then 'Burn image'.
  4. Select the Ubuntu CD image file you want to use, then click 'Open'.
  5. In the dialog, click 'OK'.

XP / Server 2003 / Vista: ISO Recorder

  1. Download and install the appropriate version of ISO Recorder.

  2. Insert an unformatted CD into your burner. (Note: one can burn DVDs with this tool only from Vista.)
  3. Open Windows Explorer, browse to your ISO file, right-click and choose "Copy image to CD".

Mac OS X

Note: To burn most ISOs, you can use Apple's Disk Utility (Disk Copy in older versions).

  1. Launch Disk Utility (Applications → Utilities → Disk Utility).
  2. If you see the ISO in the left-hand pane, select it.
  3. Click on the Burn button in the toolbar. (If you did not select the ISO in step two, you'll be prompted to find it.)
  4. Ensure that the "Verify burned data" checkbox is ticked (you may need to click on the disclosure triangle to see the checkbox).
  5. Click on Burn. The data will be burned and verified.

Ubuntu

  1. 将空CD盘插入刻录机。这时"CD/DVD创建者"或"选择光盘类型"窗口可能会弹出来。把它关闭,我们不使用这个。
  2. 在文件浏览器中浏览至下载的ISO镜像文件。
  3. 右键单击这个ISO文件,选择"写至光盘"。
  4. 在"写光盘至"对话框中,你可以见到"文件映像",和你的CD光驱(刻录机)。选择你的刻录机,刻录机在这里可能被显示为如"BD-MLT UJ-210S"之类。
  5. 选择写入速度。如果你正在刻录的是Ubuntu的LiveCD(将要引导用的),推荐使用一个尽可能低的速度。
  6. 开始刻录进程。
  7. 在刻录完成后,校验一下你的CD中应该有了多个文件和目录,而不是只有一个ISO文件。这样才知道刻录过程是正确的了。

如果你想从命令行刻录,请参考CD/DVD刻录页面。

Kubuntu

  1. Find the ISO image in the file browser (available at System Menu > Home Folder on bottom of the screen next to KMenu.)

  2. Right click on the ISO → Actions → Write CD Image with K3b...
  3. K3b will now automatically verify the md5sum, make sure these match.
  4. Place Blank CD in burner and click on start.

Xubuntu

  1. Launch the burning tool, xfburn (available at Applications > Accessories > xfburn.)

  2. Choose from the main toolbar, or from the menu Actions the option "Burn CD Image",
  3. From the Burn CD Image dialog box, click over (None) from "image to burn", and find the ISO image in the file browser
  4. In the dialog, click 'Burn Image'.
