Windows isn't functioning properly due to a change in the partition designation.
You have a fresh empty SSD, and Windows labeled it with 'D'. After restarting, your C: drive appears as D: while the empty D: drive is shown as C:. When you open Windows, it takes you to the recovery screen, and you can use CMD to rename partitions. To find the right partition, check the partition table or use a tool that lists available partitions and their labels.
Remove the extra drive, confirm if your boot drive is still linked to d:. If not, insert another drive, format it, assign it to K: or a similar location.
Review the bios settings and verify the boot sequence. Ensure the new drive is placed correctly in the boot order so the system boots properly.
Thanks for the update. I'm surprised I hadn't considered swapping out the drives earlier. It turned out fixing the boot sequence wasn't as simple as I thought. I managed to create a USB drive to recover Windows and changed the letter assignments, but it didn't save properly. After rebooting, the system still shows the SSD as D: instead of the intended drive. I'm not a tech expert and don't understand how this works, but I'm wondering where Windows stores the assigned drive letters—on the boot partition? Could I manually edit the part of my SSD that holds that information and change it myself? For instance, by installing Linux on one of my empty drives and exploring the other SSD? My main concern is not reinstalling Windows since I didn't back up anything. I didn't expect to damage my system this way.
I reinstalled Windows on a blank drive and captured a screenshot. My current clean installation is on c:. The old Windows version remains on wd_black, and I’m checking if it’s feasible to bring it back. All files appear intact, including the 449 and 99MB partitions, which seem to hold system files.
In the recovery console you can perform these steps from the command prompt (unplug the C: drive if needed). List available volumes, pick the target volume, set the letter or use PowerShell to assign a new partition letter. Change “*” with the actual volume number and “F” with your desired letter. This should allow creating a bootable recovery disc in backup & recover (works on Windows 10).
Hey, thanks for your response. I resolved the problem and wanted to pass along the solution for others facing similar challenges. The main issue was that Windows wouldn't boot on my new SSD despite it not being installed properly. It displayed a blue screen with the error code 0xc000000e, which suggested a missing or inaccessible device. Initially, I suspected the drive letter had changed, just like shortcuts fail when you rename a folder. When I ran "bootrec /ScanOs" in Command Prompt, it confirmed no Windows installation was detected. I tried forcing the boot from C: by assigning it manually, but it still didn’t work. Eventually, I discovered that Windows automatically sets the boot drive to C. My approach wouldn’t have succeeded anyway.
To fix it, I used a USB stick containing a Windows installer to access the recovery menu. From there, I navigated to Troubleshoot → Advanced Options → Command Prompt and typed "notepad" to view the This PC page. This helped me locate my SSD. If it had been labeled with letter K, I would have executed commands like:
>bootsect /nt60 K: /force /mbr
Then followed by:
>bcdboot K:\Windows /s K: /f ALL
This resolved the issue. After removing the USB stick and restoring my other drives, I reinserted the SSD with higher boot priority, and Windows booted normally again.
