I had a Windows 7/Ubuntu dual-boot set up on my laptop. I deleted Ubuntu, and when I load up my computer, I am now met with a screen displaying the following:
error: no such partition. grub rescue>
How can I have my computer boot straight into Windows 7 again?
Solved: I created a win7 system repair disc using another machine, and fixed the problem using the bootrec command within command prompt.
The easiest method is to boot up with your Windows 7 disc, choose System Recovery Options and then click Startup Repair. That should generally remove grub from your master boot record and allow you to boot into Windows normally.
Reinstall the windows bootloader http://www.howtogeek.com/howto/33433/restore-the-windows-boot-loader-after-an-ubuntu-update/
The Ubuntu partition is an extended partition. If you are in Ubuntu, C:(os) is mounted in Ubuntu with wine.
You have to boot with Windows rescue-cd and go to command prompt cmd. Use diskpart more information diskpart/help
Then list disk select disk list partition select partition => set c:os active
Reboot
With easeus partition master you can change extended partition into basic of logical
Install GRUB on Windows if you still have to choose between Ubuntu / Windows during startup.
