  1. System Not Booting After Update - Drive Letter Changed From C To E


    My system has been unable to boot for a month or so now. Finally bought a new SSD planning to replace my OS drive. An IT friend of the family recently visited and had a look. Diagnosed that the drive letters got changed after an update, or something similar. The system was running ok after I did the update but shortly after, crashed and refused to boot.

    Does anyone know a way to fix this? It also won't run safe mode, but when our friend was checking it. The file system was in tact. Just has the wrong letter so the system doesn't recognize it.

    Changing the system volume drive letter safe?

    The operating system WAS on c:\ (before I changed windows over to my SATA), NOW it is on E:\. Keep in mind I have 3 hard drives at the moment.

    Changing the system volume drive letter safe?

    It depends. Need some more information. Is your boot volume c: ? If so, then others can be changed around as needed, but there may be collateral damage. Usually, if there are pointers set in the registry, as long as you use the storage management plugin to change the drive letter assignments, most things should work.

    Trouble comes in the form of applications that keep file system information (folders, path names, etc) in files that are stored in directories during installation. Those usually cannot be changed easily, unless you know that they are there and where they are....

    What drive letters are you trying to change specifically, and what is the operating system

    System Not Booting After Update - Drive Letter Changed From C To E

    Changing the system volume drive letter safe?

    Ever since I reformated, my drive letters have changed besides C:\ and I would like to change back the other 2 drive letters.(One being the system volume letter) just so the programs I use to have still work. Is this safe? What are some negatives?
