-----------------------------------------------
3q)::same question grub has been cuurepted,if i have duel boot(windows+ubuntu),instead of installing ubutntu/ubutnu grub loader,can we do only windows as working(means i decided to remove the ubuntu , i want use the only windows,without distrubence the windows data(if i have some data in windows))

You could make a folder and mount the install then access the data - assuming that yourt buntu is on sda1 and is ext4

If you wanted to get at data in your home


Windows - use whatever you have to reinstall the windows bootloader - no idea how to do so.

For my case, I purposely NOT to install grub in MBR,
I use EasyBCD to add ubuntu to Windows 7 bootloader.
