Error message displayed: "No Operating System found, press any yet to restart".
Hello, I recently upgraded my PC with a TUF Z970 Pluss motherboard and connected four drives—two NVMe and two SSDs. In BIOS I see all devices recognized without issues. I set the boot order so the EVO 970 Pro (where Windows is installed) comes first. After saving and exiting, everything works fine for hours. However, when shutting down and trying to restart, the system freezes into a black screen with an error saying "No Operating system found." In BIOS I can manually select the bootable drive from the menu and it restarts normally. The challenge is that I have to enter BIOS each time or the restart fails. How can I resolve this?
Try skipping every other drive on your system, start up using the default one (no other boot options), then reinstall the drives one by one. It might help to check which drive is causing issues, though it should still work even if you install them all at once.
You should be able to access the system's startup settings when the POST screen shows up, typically by pressing F2 or F11 during that phase. Leaving your boot configuration in the BIOS might be as easy as a faulty CMOS battery; it needs a minimum of 2.9 volts to function properly—below that level suggests it’s time to replace the battery.
It's also possible the UEFI partition needed for booting has been moved to a different drive. Windows often tries to place it on the boot drive during installation, which can be inconvenient. The best solution was to install Windows without the boot drive yet, then add the other storage drives afterward. This should resolve the issue.
I'd also verify that specific M.2 connections don't deactivate the SATA ports you're employing. This was a typical concern for older Z390 boards.
The mainboard is monitoring each storage device. All of them appear and can be chosen during startup sequence.
However, all these drives were previously installed on the same setup. What I did was connect them to a different motherboard.
It's possible your mainboard lacks the pre-boot storage controller drivers. Try installing from a blank disk, then place the Intel driver files in a folder on your Windows install USB. Access them during the BIOS setup after the first install. NOTE: I didn't know your operating system was installed. Windows 10 may work on legacy drives (MBR), but UEFI systems won't recognize them unless configured properly. Ensure your BIOS is set to UEFI as well.
It's irrelevant how long it was stored on the shelf at the warehouse before shipping. Generally it's fine since CMOS batteries can last many years in a computer, though a faulty battery could cause issues.
