Linux (ubuntu 11.04) is not removed from my system?!
 

Hi all

I had Windows 7 on my laptop and then I installed Ubuntu 11.04 server edition on my hard disk (Dual booting).
After that, my work with the linux finished and I removed it using the Windows partition manager!
I expected that the linux to be removed completely from the hard disk,
But now, when the system boots, the GRUB boot menu is appeared and there is no Windows option to select!

Then, I can't boot into Windows because it is hidden and also the GRUB is shown (However, I removed the linux using partition manager!)

My Questions:

How could the linux be cleaned from the disk completely and How could the Windows be appeared as a boot option upon turning on the system?

Please help me.

TIA

Perhaps this will help

To correct the Windows 7 boot -

Put the Windows 7 disk, and boot from the disk.
Then you have to find the command prompt.

Enter the following two commands at the prompt -

Removing Linux partitions will NOT affect a Grub installation. Grub is a boot loader that usually installs to the MBR, which is not affected by removing the Linux partitions. On top of that, deleting partitions will cause boot failures for the remaining systems as the partition counts have changed.
