use expert or custom setting.... then you can customize the ubuntu installation.

yeh , but , my problem is that can not find out what paramete to be able customize ubuntu as the boot time by CD . Please read my topic carefuly before tell me something

Please read my reply carefully.......

When you boot with Ubuntu CD, you get prompt, right??!!! Press F3 ( if I am not mistaken, maybe F4, F5, F6 ), you get this message:

BOOT METHODS

Availabel boot methods:

......
expert
start the installation in expert mode, for maximum control

custom, custom-expert
minimal system install. Recommended for servers, where the system administrator will install custom software, and where a complete graphical desktop environment is not desired.

I am not sure you can avoid installing grub in mbr by this setting. However that is very easy to fix.

thank you very much , that the way I want to know
