ubuntu7.10 installed to 3D open

Tired for several days, reinstalled more than a dozen times and finally got ubuntu7.10 to the perfect state I think. Now summarize the installation process (recorded in order of operation):

Under XP, whether you use pqmajac or other hard disk partitioning tools to separate 10G spare partitions (10G try in the experimental stage), I don't know whether it is necessary to put spare partitions at the end of the hard disk, it seems that using the middle partition will cause installation errors.
Start the installation, the simple steps are omitted... Here is the partition, a swap: 2G, logical, end. One/, ext3, 8G, start. Another thing is to keep the network open during the installation process, because the language pack needs to be downloaded during the process.
The installation is over.

In order to avoid errors in the subsequent configuration process, it is recommended to use clonezilla live (ghost 4 linux) for backup. Clonezilla download address: [url]http://clonezilla.sourceforge.net/download/sourceforge/[/url]
Download *.iso to carve a disc, boot from the disc into clonezilla live for backup, it is quite simple to use.
