A friend of mine had Windows 7 and Windows XP running in his Sony Vaio. I replaced Windows XP with Ubuntu 10.10. After that the laptop directly boots into Ubuntu. Even the grub menu does not appear during startup. I tried sudo update-grub, sudo update-burg but windows was not recognized.

How can I solve this issue?

  • To restore the Windows 7 bootloader, you must first boot off your 7 installation DVD.
  • When you get to the Regional settings, select your Location/Keyboard setting then click next. On the next page you must click on Repair your computer.
  • On the next page, if it finds your Windows Vista/7 installation, make sure it is UNSELECTED before clicking next.Then click on Command prompt.

  • From there, type in the folowing,

    bootrec.exe /fixboot

    bootrec.exe /fixmbr

  • Now close the two windows and click Restart.

I actually don't want to reinstall windows...it takes lot of time to install additional software... – Chethan S. Dec 22 '10 at 9:07
@chethan: If Windows does not appear in the boot menu, I think you will need to edit /boot/grub/menu.lst.. Please try that.. – Sen Dec 22 '10 at 9:13

Actually the guide will work only for grub versions < 2.0. From karmic onwards, grub 2.0 is the default. – apoorv020 Dec 22 '10 at 10:40

You should check your grub configuration to see whether the timeout option has been disabled or something.

For old grub versions, see this link. For newer versions, see this link.
