N.B. If this is the ancient Dimension 5100 (2005 model)... then you will be restricted to 32 Bit Windows and even then it won't run Windows 10 very well...
You can Download a Windows 10 .iso from Microsoft and directly clean install Windows 10 on your Dell system. You will not need to input your Product Key as your system is already a Windows 10 Device however you can input the product key from the Windows 7 Retail License.
You can get the Windows 10 recovery media from Microsoft (the system will already have a digital entitlement since Windows 10 was already activated on it).
