Windows 10 is starting from two storage devices.
You've set up your system correctly and are experiencing unexpected boot behavior. The issue seems to stem from the way Windows detects and boots from the drives. Since you're trying to use only Disk 2 but also getting a boot from Disk 1, it might indicate a conflict or misconfiguration in the boot settings. Checking your BIOS/UEFI options for correct drive selection and ensuring no conflicting partitions are present could help. If the problem persists, reinstalling Windows might be necessary. The forum advice likely refers to using an older system image or repair tool to fix boot issues.
This happens because OS installations are duplicated across drives, which can lead to conflicts. It’s an OS-related issue. Just let me know.
Consider linking just the O/S drive (remove the SATA cable) for a fresh setup. Perform a clean installation there. Afterward, connect the remaining drives and format them using Windows. Good luck!
I initially attempted a repair, but somehow the boot process failed and removing all drives except the SSD led to BIOS startup instead of Windows. I resolved it by reinstalling Windows using only the SSD, and later reinserting the remaining drives and formatting them. I don’t know why Windows decided to boot from two drives at once.
It doesn't start from the two drives. It launches from the new drive using the old boot file. What's happening is that the old drive likely contains a boot sector, and Windows won't generate a fresh one on the new disk. If you have an existing OS on the old disk, you can switch between them (multi-boot). This approach helps maintain the older system. A common practice is to set up Windows without connecting any additional drives.
Confirm that the drive connections follow the correct order. The primary operating drive should be connected to the first port (SATA-0 or SATA-1).
It's fine, there is no real issue. Just that if one day you decide to wipe the OS drive and re-install, you may have the setup put the boot partition in the other drive, so you may need to restart and this time unplug all SATA cables again. Your can flip the SATA cable around right now (well, with your system turned off), even if you have everything setup already, system/Windows doesn't care. You'll turn it back on, and the system will act like nothing has happened.
