sir, i have created the xp power pack cd by burning the crteated iso image, by the way i have created the tripack using PowerPacker_v1.0RC7.1.
if i boot from power pack and press F1 i have seen this

-UNATTENDED = Install with no user prompts.
-With DriverPacks = Install with added Driver Support. (Recommended)\n"
-REGULAR = Install will prompt you for all information during setup. \n"
No DriverPacks or Applications will be installed. \n"
Very useful if you are wanting to do a Windows repair. \n"


Press any key to return to the Main Menu...


is there any instruction on how to install using unattended,With DriverPacks and Regular Mode

Do you have an unattended script made (WINNT.SIF)?

For help on making an unattended disc, goto MSFN, and you'll find the information on how to create an unattended disc.

An unattended disc simply goes through the installation for you, no user interaction required. The driverpack option has the drivers added (unattended?) and the regular option is just a normal XP installation, no driverpacks and no unattended.
