I had a Win 7 64bit and 10.04 dual boot. However, a friend mistakenly formatted the Ubuntu partition with my partition software (Paragon Partition Server 10) and after a restart i was greeted with a black screen 'no boot partition'. My question now is how do i recover my Win 7 boot loader and install 11.04 when it drops. Thanks in advance
there are many possibilities :
Select among your preferences :
the fastest simply reinstall your ubuntu to have your grub2 refreshed.
the smartest a good option is to learn
You may edit the /boot/grub/menu.lst file in any text editor, and change the line which says:
to the number of your choice. Grub counts from zero, so the first item in the grub menu is 0, second is 1 etc etc. The little 'Other Operating Systems:' dividor in Grub DOES count as a menu item too, so don't forget to include it in your count
You will need to use sudo or gksudo to gain root priveleges in order to edit /boot/grub/menu.lst, so you should press alt+f2 then in the box, type:
Boot up with your Ubuntu CD, you should be able to access your windows 7 partition.
Plug in an external hard drive and back up your data from win7 to external hard drive.
Then find a win7 CD and use the repair tool. You should be able to re install the windows boot fairly easily following instructions if you get a CD somewhere.
But back up your CD above all. It's your priority right now.
Boot the windows install cd, choose the recovery console option, and run the FIXMBR command.
