Wrong Driveletter
After you have done a windows reinstallation and you notice that the hard drive is a drive letter other than C, this may be due to a zip drive, flash card reader, or a printer installed during the install.
Another words, you have a printer, USB device, USB card reader, zip
drive or other drive connected when you start the install of
windows. When you are done with the install, you notice that the
zip, flash card, USB device or other device is listed as drive C and
your hard drive is listed as drive F, G, H or other drive letter
besides C.
This will cause problems with some programs. Some programs require
the C drive to be the hard drive.
You have to make sure that the following has been disconnected
-
Zip drives (internal and external you will need to disconnect them and then reconnect them after the setup is complete)
-
Flash card readers
-
Printers
-
USB cards (such as PCI USB card readers)
If you do not disconnect them before windows install, windows will make them drive letter C and the hard drive drive letter E, F or other designation. Then when you try to install drivers or programs, they will not install. Some programs will install but some will not.
The only way to fix this is to disconnect the drives mentioned above
and start all over.
