Installing Ubuntu to new PC with RAM > 4GB and nVidia graphics card

Intel Core2Quad Q9550 @ 2.83GHz
Asus P5Q
8G DDR2 800
EN9500GT OC/DE/512M
SATA ExcelStor Technology J8160S 160GB
SATA Optiarc DVD RW AD-7200S


Ubuntu 7.04 have problem while starting X

Ubuntu 8.04 lte, Ubuntu 8.10
no matter AHCI or not,installing to a SATA disk, or USB to IDE (WD1600JB WD Caviar SE, IDE 160GB)
Stop while installing system around 50% with following reported:
The installer encountered an error copying files to the hard disk:

[Errno 5] Input/output error

This is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment.

PAE in 8.10 desktop?
http://ubuntuforums.org/showthread.php?t=957430
The server kernel has been compiled with PAE (which solves the problem) and with Xen related things. The latter prevents the installation and use of the NVidia proprietary drivers. Depending on your configuration, this may create another problem, which can be solved by compiling your own kernel, with PAE but without Xen support.

32 bit Ubuntu with 4GB+ of memory

RAM >=4G requires to enable PAE
nVidia driver cannot work with Xen enabled

Ubuntu desktop have PAE and Xen disabled
Ubuntu server have both PAE and Xen enabled

but why Ubuntu desktop installation would failed? (unknown)

Solutions
  1. Remove RAM to size < 3GB, install ubuntu desktop, rebuild kernel to enable PAE, re-insert RAM
    (Ubuntu could reboot with 8GB RAM installed and w/o PAE enabled, but there is only 3292MB RAM available, shown on htop, while w/ PAE,8106MB.

    Besides, enabling nVidia accelerated graphics driver w/o PAE enabled w/ 8GB RAM installed, error like the following might be seen while restarting:
    Ubuntu is running in low-graphics mode
    The following error was encountered. You may need to update your configuration to solve this.
    (EE) NVIDIA(0): Failed to load the NVIDIA kernel module!
    (EE) NVIDIA(0): *** Aborting ***
    (EE) Screen(s) found, but none have a usable configuration.

  2. Install ubuntu server, rebuild kernel to disable Xen.
    (not tried yet)

To Enable PAE
-> Processor type and features
-> High Memory Support
-> 64GB

    (the chosen driver has "restart" sign before it)
  2. restart X or reboot

ubuntu server kernel misidentified as xen?
http://www.nvnews.net/vbulletin/showthread.php?t=112102
I'm trying to install the 169.12 driver (from nvidia's .run file). The kernel I am using is from Ubuntu 8.04, the "2.6.24-16-server" kernel. The installer refuses to install into this kernel: it reports
Code:
The kernel you are installing for is a xen kernel.
