Removing Ubuntu from Dual Boot PC

[Desmond]

Guys,

I want to remove Ubuntu from my system, but, I lost my Windows 7 beta DVD, so I cannot restore the MBR. Are there any alternatives?

 

[Anorion]

try diskmgmt.msc

I can delete the Ubuntu partition from there, but what abt the MBR?

make empty disk space, then extend the current partition, or create a new one with the empty space. diskmgmt writes the MBR.
