Why can't I change my SSD from (J:) to (C:) & how do I remove Dual Boot?

By Robert Wright ·
The System (C:) was cloned using Macrum Reflex and restored to the SSD (J:), and the
BIOS was changed to boot from the SSD. The system would not boot, so a repair was performed using a repair disk. When the system was started there was a dual boot both named Windows 7 Professional (Recovered). Booting the top one, the boot drive is the SSD, but the drive letter has changed to (H:). Booting the bottom one, the boot drive is the (C:) drive and the SSD remains (J:). Physically disconnecting the (C:) drive leaves two seemingly identical boots from the SSD.

My plan was to first get the (J:) drive letter changed to (C:), and then worry about the dual boot later. Using Disk Management, I changed (C:) to (K:), and was then going to change (J:) to (C:). When I changed (C:) to (K:), a message in Disk Management said that a reboot was necessary to make the change, so I re-booted. Disaster! A note on the lower right corner of the screen stated that this was not a genuine copy of Windows, and would not open the desktop. I restored the SSD again, and I am back to the two bootable versions.

Thus my two problems:

1. How can I rename these drives?
2. How can I remove the dual boot?

Any help would be appreciated.

I've run into this before where Windows (XP) got installed on drive H: because a card reader was present. I spent a fair bit of time looking into this and found there was nothing that could be done about it. I did the same as you (but got worse results from memory... can't remember what exactly... was a long time ago). I then researched it more and found that it was not possible to change because there are several spots in the registry where the drive letter is stored. I searched for an updated all of these anyway, but without luck (may have stopped the computer booting altogether).

Perhaps there's something you can do in Macrium to stop this from happening, but I once Windows has decided it's booting off J: I don't believe you will be able to do anything to convince it to do otherwise. Perhaps Windows 7/8 has changed, but I highly doubt it.

I reset BIOS to boot from the (C:) drive, and things are as before. Is there some cloning software that will clone the drive and preserve the drive letter?

I'm sorry - misunderstood your question slightly. It just sounds like there's a bit of confusion because you've got both the original and the clone drive plugged in. Whichever one you've booted from should believe it is C: (ignore your BIOS if it refers to "C: Drive" as that won't necessarily be correct).

To check the situation set the BIOS to boot from whichever drive you want, boot up and open a command prompt. Type in set and hit Enter and look for the value of SystemDrive. It should be C:.

No cloning software should affect the drive letter (since it's set in the registry). I haven't used Macrium a lot, but have never had issue when using it.

you can't leave both the original & the Clone in the same system

by Who Am I Really In reply to Why can't I change my SSD ...

when you clone you must remove the original and install the clone into the system in the place of the original

windows throws mega fits when it finds an exact copy of itself in the form of a clone with same disk signatures etc.

offline cloning gives better results as windows just boots up where it was shut down from, with the only difference being the disk,
you'll get the new hardware found and then it might ask for a reboot

when cloning to SSD from HDD you need to run the Windows Experience Index again to have it discover it is now installed on an SSD to make the system adjustments for SSD

I use Clonezilla for cloning win vista / win 7
and have never had a problem

install the original C: HDD into the system alone and start it up
repair the install if it doesn't boot as C:

if it boots as C: then do and offline clone to the SSD and install only the SSD so that it will boot as C:
then you can either keep the original as a backup
or wipe it with another system before reinstalling it into the system

note the following changes:
