Hi all. I'm running TI9 v3677 on my fast laptop with two externally connected USB drives. One is my external F drive. The other is a temporary USB enclosure with my desktop's internal hard drive in it. I restored my desktop's image from drive F to its internal hard drive mounted in the temporary USB enclosure. I could not assign C as the drive letter because it was not available to select. I chose Z as a temporary letter. I put the internal drive back into the desktop computer but it won't boot because it's drive letter is now Z. Could someone please help instruct me as to how I can change the drive letter from Z to C so it will boot? I need to be able to do so while the drive is mounted in the desktop. Thanks in advance for your suggestions.
