I just installed ubuntu 11.10 alongside with Windows 7. Ubuntu starts and work fine. Instead, when i click on the last option:

windows 7 (loader) (on /dev/sda1)

the bootloader reload itself and doesn't start windows 7! So now i can only use ubuntu! For me ubuntu is good etc, but i like also to use windows if possible... can you help me?

Here's my Boot Info Script: http://paste.ubuntu.com/5655022/

  • Hmm looks like you have Wubi installed. Windows might cause problems if you have Wubi and a full Ubuntu installation on the same computer. – Emerson Hsieh Mar 28 '13 at 12:37
  • Also, try running Boot Repair from a Live Ubuntu CD or USB. It might fix your problems :) https://help.ubuntu.com/community/Boot-Repair – Emerson Hsieh Mar 28 '13 at 12:38
  • is the same, doesn't work, it's wise for you try to destroy wubi folder? this is the output: http://paste.ubuntu.com/5659502/ – pietrod21 Mar 29 '13 at 21:44

In ubuntu open a terminal and run

sudo update-grub

The system should regenerate all bootable kernels and chain loading boot partitions

A word of note, it is very possible that grub is fine but the Wondow boot sector is broken. Grub chainloads the Wondow bootstrapper.

you may need to run a repair from Wondow disc/media so its the only bootable system then use the ubuntu livecd/disc to re-install grub
