sorry for my very bad english!!

so I want to reinstall a computer remotely with 
At the first time Unattended.Sourceforge recreate partition and must 
reboot. After It reconnect to the TFTP server to begin the windows 
reinstall. Until there it's ok!
But during the windows install the computer reboot and it must reboot on 
localboot and not on the network!

So the idea is pxelinux write a tempory file on server with a value and 
read this value who decrease on each boot (by connecting a network 
drive) and if this value is equal to zero thus pxelinux boot on 
localboot (default) else it's boot on network!!
