it should be able to see that another partition (Windows 7) exists and perhaps view folders and files. If not, then Win 7 may be gone. You'd need to delete any and all partitions created by Ubuntu and probably just need to wipe the drive clean before reinstalling Win 7.
Hello
I installed and using windows 7 for 4 months, i tried to install Ubuntu in dual boot with windows seven. I installed Ubuntu in a separate partition.. all gone well and after Ubuntu installed and restarted,i cannot access Windows 7.
I tried to reinstall Windows 7.. SETUP NOT SHOWING ANY HARD DRIVES and asking for driver files.. Ubuntu is not necessary for me! I need Windows 7!!
Please help me!
