Only starts after entering BIOS settings
I recently assembled my computer last week. When I power it on, instead of launching Windows 11, a message appears in the screen indicating no bootable device detected. If I navigate to BIOS and select the boot drive there, it starts up normally. My boot priority settings seem correct, and the drive appears fully functional as long as I follow the BIOS steps first. I’m certain the PC will work properly if I proceed through BIOS. My motherboard is an ASUS ROG Strix B650E-F, and the SSD is a Samsung 980 PRO, both brand new at the time of installation. I updated all drivers and ran the Windows Startup Repair.
When you navigate through boot settings (usually F11) and pick a drive, does it function properly? Is there no need for USB devices linked with an OS image or an MBR? If you're certain about the correct boot sequence, remove the secondary drive while keeping the main one active with your operating system running—would it boot if only that was connected without going through the boot menu? Your MBR might be configured in an unusual way.
It starts when I choose it in the boot settings, which is what I always have to do. I’m not sure what an MBR is or how to verify it, so I’ll look into it. When I first installed Windows, I booted from a USB drive and used the installation setup to select the correct partition.
Make sure you check the bios and boot sequence, switch to the first available bootable device, save and close the bios. Then adjust the MBR from the wrong drive—either unplug the secondary drive, reinstall Windows on the primary one, and reconnect once done. Placing the MBR correctly is tricky if you're unsure.
