Problem encountered with PC setup, system indicates no bootable drive available.
You just assembled your first computer and are feeling a bit lost. You considered using parts from your old machine, but the new one doesn’t see them as bootable drives. However, it does recognize them. You learned that both drives needed to be connected together for Windows to start. Here’s a quick overview of the components you mentioned:
- Motherboard: H81M-E34
- Old PC Hardware: Samsung Evo 870 1TB Seagate HDD
- New PC: 1TB Seagate HDD
- New PC Storage: Asus ROG Strix B660-A
Make sure the drives are properly connected and try booting again.
There seems to be a new BIOS rootkit threat linked to Asus and Gigabyte H81 motherboards, primarily affecting devices in Asia. The exact purpose remains unclear, but it's believed to have been active since around 2016. It likely targets boot sectors to prevent successful installations on other systems. I don’t know the full compatibility details of the H81—whether the SSD uses M.2 or standard SATA, if it’s formatted with FAT32 or NTFS, and whether it uses a partitioned GPT or MBR. These specifics could influence its behavior.
Perhaps it's not the main concern, but I've heard about cases where Windows could store some boot files on separate drives within the same system. If that's the situation, it's possible that changing the connection order might stop the system from starting. I think this was more related to RAID setup.
It looks like your new board includes an Intel rapid storage feature. Check the BIOS settings and ensure it’s disabled. This issue occurred with me too—neither of my SSDs was recognized or available to be set as a boot drive. It seems you didn’t modify the previous SSD/HDD and simply added it to the new PC. If that’s the case, you’ll likely need to install a fresh Windows operating system. I had two SSDs during setup; one already had Windows 10 from another machine, while the other was blank. The new OS won’t boot with the old one because hardware and drivers differ, so a clean installation is necessary to match the new hardware requirements. Given your older board is quite outdated compared to the newer B660M board, you probably can’t reuse the existing drivers. Therefore, I recommend creating a fresh drive or partition and preparing a bootable USB for Windows installation before proceeding with the new OS.
You can upgrade to the latest operating system by installing it on the existing SSD. Make sure you allocate a minimum of 70GB of empty space. When using the bootable USB installer, you can set up the new partition for the OS before beginning the installation. There are many helpful tutorials available from Google.
