Issues during the process of updating to a new operating system on an SSD while retaining the existing one on an HDD.
Issues during the process of updating to a new operating system on an SSD while retaining the existing one on an HDD.
Hello. On my PC there are two HDDs (one for general use and one for old Windows) plus an SSD. I installed Windows 10 on the SSD while keeping the older HDD running with Windows 8.1 to move the files I needed. Although I faced no issues at first—like setting the SSD as priority in BIOS—I encountered problems later after changing my case. First, the boot manager appeared and asked if you wanted to start from Windows 8.1 or Windows 10. I checked the BIOS, and it used the storage HDD as the first boot option by default. Still, Windows 10 worked fine. But the boot manager kept interrupting me. After some research, I decided to disable both HDDs in CMD, which was a mistake. My PC wouldn’t start at all with the message “No operating system found…press ctrl alt del to restart.” Interestingly, even after removing both HDDs and leaving only the SSD, the PC wouldn’t boot again. Eventually, I managed to restart using a bootable USB drive with Windows → cmd → set 2 HDDs active. My question now is: can I make the SSD the sole bootable device and keep the old HDD just for storage, without losing any files? And if that’s not feasible, what should I do next? Thank you.
I'm worried about fixing this right now since I rely on powerful programs for my university and don’t have much space on my HDDs. It looks like my Windows 10 might be affected, maybe the disks are corrupted too. Could I attempt to repair my Windows 10 somehow or look for a faster fix in the meantime?
Only the HDD partition has issues during startup, while the SSD works fine. Try booting from a Windows installation USB only on SSD. Before future installations, disconnect the old drive.
