Did I install Windows wrong?

When I built my computer, I didn't know much about installing Windows 7. It was my first time ever installing Windows and I think I messed up. I created a partition and I couldn't install Windows on it. Now, in Disk Management, I have an undeleteable 101 MB partition of unallocated space and no system reserve partition that I've seen people have. I don't know if it's the cause of it, but I have weird stuff happening in Windows like my icon cache being constantly corrupted

 

Should I reinstall Windows? Would it fix my icon cache being constantly corrupted?

Did you install it from a disk or a usb? Could have been a defective disk. 

You can't delete a partition of unallocated space, because its already deleted. thats what unallocated means. 

Is it near the beginning? or the end? 

In the picture, is it like this

[(unallocated)|(windows partition)]

Or is it like 

[(Windows partition)|(Unallocated)]

 

If its like the second, right click on the windows partition, and click "Expand" and follow the prompts to claim the space.

If its the first way, then leave it. It's a blank spot on the hard drive, and will just sit there doing nothing, not hurting anything.

 

If you do a reinstall here is a good guide.
