Why it does not show the Format option during reinstallation of Windows 7?

Question

I have Windows 7 installed in my computer. Now I want to reinstall it. I have 500 MB free of 19 GB on my C drive. When it comes to the step of selecting a drive to install the OS, it says the C drive does not have enough space. But the concerning issue is it does not show any Format option either, so I cannot reinstall Windows 7.

Solution

You need to delete both partitions when you get to that screen so that you see one whole Unallocated space.

There should be a Drive Options (advanced) button/link in middle-right.

You can refer to the resources below:

Are you currently logged into your Windows OS while doing this or did you Boot from disc?

There is also a note at the bottom: Windows cannot be installed to Disk 0 Partition 1. (Show Details) so I would like to know, what are those details?

@alvi I updated my post

In your first image/screenshot why are you creating a new partition if all you have is one whole disk with 127.0 GB unallocated space. Just click the Next button and install Windows

If you do that, it will create a 100MB "System Reserved" partition.

The method I described won't create the 100MB system reserved partition. The gui does not create it if the selected partition is Active. Which is not accessible. This method is used mostly in business advanced users where IT Support are available if things go wrong.
