Hello, pc hangs on first boot then after restarting the pc it asks to delete restoration data and proceed and pc boot normally. I have added new DVD writer some days before.

Try booting from a XP disc and select R for recovery. Then try to do a chkdsk /r to repair. If that doesn't work, go back in and try fixmbr to fix the master boot record, and the fixboot which writes a new partition boot sector.
