デバッギングの目的で、anaconda はインストール アクションを /tmp ディレクトリ内のファイルにログします。 これらのファイルは以下のものがあります:
/tmp/anaconda.log
全般的な anaconda のメッセージ
/tmp/program.log
anaconda で実行される全ての外部プログラム
/tmp/storage.log
総括的なストレージモジュールの情報
/tmp/yum.log
yum パッケージインストールのメッセージ
/tmp/syslog
ハードウェア関連のシステムメッセージ
If the installation fails, the messages from these files are consolidated into /tmp/anaconda-tb-identifier, where identifier is a random string.
All of the files above reside in the installer's ramdisk and are thus volatile. To make a permanent copy, copy those files to another system on the network using scp on the installation image (not the other way round).

10.1. You are unable to boot Fedora

10.1.1. Are You Unable to Boot With Your RAID Card?

If you have performed an installation and cannot boot your system properly, you may need to reinstall and create your partitions differently.
Some BIOSes do not support booting from RAID cards. At the end of an installation, a text-based screen showing the boot loader prompt (for example, GRUB: ) and a flashing cursor may be all that appears. If this is the case, you must repartition your system.
Whether you choose automatic or manual partitioning, you must install your /boot partition outside of the RAID array, such as on a separate hard drive. An internal hard drive is necessary to use for partition creation with problematic RAID cards.
You must also install your preferred boot loader (GRUB or LILO) on the MBR of a drive that is outside of the RAID array. This should be the same drive that hosts the /boot/ partition.
Once these changes have been made, you should be able to finish your installation and boot the system properly.

10.1.2. Is Your System Displaying Signal 11 Errors?

A signal 11 error, commonly known as a segmentation fault, means that the program accessed a memory location that was not assigned to it. A signal 11 error may be due to a bug in one of the software programs that is installed, or faulty hardware.
If you receive a fatal signal 11 error during your installation, it is probably due to a hardware error in memory on your system's bus. Like other operating systems, Fedora places its own demands on your system's hardware. Some of this hardware may not be able to meet those demands, even if they work properly under another OS.
最新のインストール更新とイメージを持っていることを確認して下さい。オンライン errata で新しいバージョンが入手できるかどうか調べて下さい。最新の イメージを使用してもまだ失敗する場合は、それはハードウェアの問題かも知れません。 一般的にはこれらのエラーは メモリーか CPU キャッシュの中にあるものです。システムがサポートする場合は、 BIOS 内で CPU キャッシュをオフにするとこのエラーが 解決することもあります。またマザーボードスロット内のメモリーを入れ換えて、問題がスロットか、 メモリーにあるのか確認することも試してみて下さい。
Another option is to perform a media check on your installation DVD. Anaconda, the installation program, has the ability to test the integrity of the installation media. It works with the DVD, hard drive ISO, and NFS ISO installation methods. The Fedora Project recommends that you test all installation media before starting the installation process, and before reporting any installation-related bugs (many of the bugs reported are actually due to improperly-burned DVDs). To use this test, type the following command at the boot: or yaboot: prompt:
	linux mediacheck
