Installed ubuntu alongside windows (windows doesnt show in boot menu that is another issue)
After loggin in to ubuntu, I formatted a partition (not one which the OSes were installed on. It had just data)
But the formatting failed and now i cant see the partition or use it. Also the
fdisk command shows the same partition twice
sda5 in the image below.
Not able to understand how to fix this so that the partition becomes usable again.
