Windows 7: Error while changing primary drive letter

Error while changing primary drive letter

I recently installed a new SSD, and put windows 7 ultimate x64 on it. this installation occurred while another instance of windows was on a separate HDD that was still installed in the computer. because of the existing install, my primary drive letter was set to D:, i have since scrubbed the old HHD and the windows installation on it. When i attempted to change my primary system drive letter from D: to C:, i got the error "The Parameter is Incorrect". Does anyone know of a way to force windows to change this?

I attempted this change through windows disk management.

*I have already backed up all information, and took a snapshot of the drive in case of catastrophic failure.

Thank you in advance for any assistance given.

You can't change the letter of the system drive, IE the drive Windows is installed on.

Your first mistake was leaving the other drive connected when you install the OS on the SSD.

If I were you I would start over with a Clean/Fresh install on the SSD. That is after you backup any data that may be on that drive and also have all other drives disconnected before you start the install on the SSD.

I agree with Edwar. A clean install is the way to go to get things corrected.

All,

Thank you very much for your advice on this, i figured that was going to be the case, but i was hopeful someone had a better idea.

@WHS Some of the programs i had installed on the computer, Mainly those provided by ASUS continued to look for a C Drive. i attempted to change it, but the software would not look anywhere else but the C Drive for the necessary files. Even though it was installed on the drive labeled D.

That's one of the reasons I always suggest a reinstall at this point. Some programs apparently still use hardcoded paths.
