Как восстановить бут-сектор windows XP из-под Linux?

_voland_:
CD\DVD-привода в системе нет

zhito:
нетбук чтоли?
проще всего загрузить восстановление системы в консольном режиме и набрать fixboot и fixmbr
потом линух с флешки грузим и grub-install

Mad_Man:
Попробуйте для начала

sudo update-grub

sergey@ubuntu:~$ sudo update-grub

Mad_Man:
Какую ошибку выбивает после выбора винды из списка загрузки ОСей?

_voland_:
А никакой... экран с мигающим курсором без реакции на ctrl-alt-del - только жесткий рестарт помогает

Mad_Man:
Винда и убунту на разных хардах висели?
