Start Windows with F8 if you still can, if not boot with windows install disk.
If your backup is on the network you might have to set the network to get to the backup, if like in my case there is no DHCP then you got more work to do.
First go to command prompt and start with:
Start /w wpeinitnext run the bellow, just make sure you put the right IPs
netsh interface ip set address "Local Area Connection" static 192.168.128.55 255.255.255.0 192.168.128.201after that you should be able to access your NET and get the restore going.
