But.
Simple procedure turned to nightmare (and - good morning, Vietnam!) - Windows7 is ruined, Windows XP is completely ruined, everything is ruined!!!1111
After almost 16 hours of YAROSTNOE DROCHILOVO I've got something: both systems are restored _almost_ succesfully. Windowseven works fine (activation is lost, I've cracked it already), but XP suffers from amnesia - she'd lost cyrillic support (?!): russian keyboard layout, russian language in dialogs, etc - everything dissapeared. I just can't reset layout switcher! trying to disable and enable it, without any positive result. Damn.
