Did you install WIn7 on F from the C partition, because otherwise Win7 should see itself as C when booted into either Win7. You should always boot to clean install.

The way a partition is deleted is in Disk Mgmt or using a Partition Manager, not yanking its files out.

But first we need to see a Disk Mgmt screenshot to see if the boot files are likely on C, as they must be recovered into F before it will be able to boot on its own. Use SNipping Tool in Start Menu, maximize window before snipping.
