Hi, I've been experiencing some problems with my Ubuntu 12.04 partition. I dual boot Ubuntu with Windows 8.1 and I wanted to delete the Ubuntu partition and install Windows 7. I booted up the Windows 7 install disk and went to install it as an advanced person. I selected the Ubuntu partition and selected format, then i got a notification saying: " Unable to format partition error 0x80042448 ". I tried searching on the internet for something similar but found nothing. Could any of you please help ?
