Ok we are in business
First let's partition and format the Disk 1 drive:
Go back to the Disk Management section and right click on the Drive 1 unallocated section and select New Partition.
In the New Partition Wizard click next. On the next page make sure “Primary Partition” is selected and click next.
Now make the size equal to the maximum (it should already be set to it), click next again. On the next page the computer will automatically choose the first available drive letter for the new drive.
Hopefully it will be G: you need to maker sure it does not assign the letter C to the drive.
If it does the use the dropdown to select G
Next the New Partition Wizard asks if you would like to format the new partition and if so what format choose, NTFS.
Do not close the “Computer Management” window until it finishes, you will know it is done when the word under the size of the drive changes from “Formatting” to “Healthy”
Reboot the system and see if your F drive is now listed as C
If not then you will have to change drive letter through the same Disk Management
Right clicking on the F drive and selecting "Change drive letter and paths"
