Where is install log file?

Just try reinstalling it. But before you install it, check the LiveCD for errors.

This might fix your problem. If it doesn't, it could be anything from a hard drive failure, to crappy memory, or even just a simple compatibility issue.

It sounds like you're talking about kernel messages. Those are stored in /var/log/messages. Older messages are stored in other files in the /var/log folder that start with "messages" (like messages.1, messages.2.gz, messages.3.gz, and so forth). Old enough archives are compressed with gzip. Even older archives are automatically deleted. If this happened recently, they're almost certainly in /var/log/messages.

On the other hand, perhaps these messages really were from the installer. Check the logs in /var/log/installer. If you need help accessing those files, please post again.

This is getting more complicated than it's worth, so I'll make a couple comments and then drop it for more important things. I looked through /var/log/messages, and didn't find the error messages in question, but while scanning spotted the following:

       agpgart-intel 0000:00:00.0: detected 7676K stolen memory

Wow! Thieves in the wainscotting. Do you suppose this might be the work of a virus/trojan horse in my Windows installation?

By the way, the Log File Viewer apparently does not look at all the available log files, particularly the /var/log files.

Also by the way, what is the LiveCD?

Marking solved; replies to queries optional.

Ed Live CD is install CD which is bootable and can be run without installing
it (it's slower of course, but fully funcional)

Well, yes, but what did Jeb E. mean by "check the LiveCD for errors". Install cannot write to a CD that has already been burned, can it?

No, it can't. But it could write in "/" partition of hard disk after formating.
"check the LiveCD for errors": When you boot CD, if you immediately press <SPACE> key, you get a menu allowing you to check CD itself.

"agpgart-intel 0000:00:00.0: detected 7676K stolen memory"

Since agpgart-intel is a graphics driver for on-board Intel graphics, perhaps "stolen memory" refers to physical RAM that is allocated for use as video RAM (and thus is deducted from available system RAM).

Just a guess.

There are plenty of scary-looking kernel messages on most Unix-like systems, but most of them are quite innocuous.

On the other hand, perhaps I'm wrong and this does refer to something bad. Not malware (not a window virus/trojan), but perhaps something bad nonetheless.

You really should check the CD for errors, as Jeb has said (and as delance has explained). If delance's explanation is not clear to you, see http://zootlinux.blogspot.com/2010/05/check-disc-for-defects-in-ubuntu-1004.html.

Also, you should check the ISO image you downloaded (from which you burned the CD) to see if its md5sum is correct: https://help.ubuntu.com/community/HowToMD5SUM

I did check the CD for errors, and it came up clean. I will check these other suggestions out.
