How can i reinstall xp if laptop is not accessable

Check the BIOS to see if you can make the USB as the first boot device, if you can then you will be able to install XP from the USB flash memory stick.
The reason why your XP installation failed is because in most older laptops, the USB port does not work until Windows XP has been installed.
Your hard disk may have an Windows XP install partition that you can access to reinstall Windows, provided you have not deleted this partition.

Download and reinstall the LaunchManager application:

LaunchManager Application for Windows 7
Acer LaunchManager Application for Windows XP
Acer LaunchManager Application for Windows Vista

update your laptop by getting winxp service pack 3, it will have your current xp to support the wireless network.

Nifty little IDE to laptop ide adapters on ebay for under $10 delivered..
remove laptop HD.. use adapter, plug into desktop as second drive.
Load up XP install to a folder.. use a decent file copier so you get hidden files. try filesync 2.xx (look for it),
Back into the laptop, try it..

Only other thing would be LEGACY USB SUPPORT in the bios and an external usb drive... Hopefully your usb problem is XP related and not hardware related..

you can run recovery using the recovery discs which should have been created by you... or you have to go into the OS to access recovery manager...

hi, check the wireless settings or reinstall the driver, let me know
