Installation Source Screen

Figure 18.8. Installation Source Screen

Select one of the following options:
ISO file
This option will appear if the installation program detected a partitioned hard drive with mountable file systems. Select this option, click the Choose an ISO button, and browse to the installation ISO file's location on your system. Then click Verify to ensure that the file is suitable for installation.
On the network
To specify a network location, select this option and choose from the following options in the drop-down menu:
  • http://
  • https://
  • ftp://
  • nfs
Using your selection as the start of the location URL, type the rest into the address box. If you choose NFS, another box will appear for you to specify any NFS mount options.


When selecting an NFS-based installation source, you must specify the address with a colon (:) character separating the host name from the path. For example:
To configure a proxy for an HTTP or HTTPS source, click the Proxy setup button. Check Enable HTTP proxy and type the URL into the Proxy URL box. If your proxy requires authentication, check Use Authentication and enter a user name and password. Click Add.
If your HTTP or HTTP URL refers to a repository mirror list, mark the check box under the input field.
You can also specify additional repositories to gain access to more installation environments and software add-ons. See Section 18.14, “Software Selection” for more information.
To add a repository, click the + button. To delete a repository, click the - button. Click the arrow icon to revert to the previous list of repositories, that is, to replace current entries with those that were present at the time you entered the Installation Source screen. To activate or deactivate a repository, click the check box in the Enabled column at each entry in the list.
In the right part of the form, you can name your additional repository and configure it the same way as the primary repository on the network.
Once you have selected your installation source, click Done to return to the Installation Summary screen.
