Upgrading the motherboard or CPU isn't working with the SSD.
Upgrading the motherboard or CPU isn't working with the SSD.
After updating my motherboard and CPU, I connected all my drives—an SSD and three 640GB hard drives. In the BIOS, everything is listed, but only one of the hard drives can be chosen as a boot device. My Windows installation is on the SSD, which was the first option in the boot menu. After the first failed boot attempt, it disappeared from the list. Why isn't my Samsung SSD showing up as a boot option in the BIOS? Two of my drives were RAID 1, possibly causing this issue. I'm unsure what will happen to them with this upgrade and don't mind the change. I've backed everything up and no longer need the RAID configuration. Still, I don't understand why the SSD isn't listed.
I've realized on these forums that many answers seem unhelpful when upgrading mobos/CPUs without a full OS reinstall—just plug it in and see what happens. I had two machines: one with the new hardware and one with the old setup. Both failed to boot Windows after the upgrade, and the repair tool didn’t fix the problem. I was tempted to do a complete reinstall on both, but I decided to review the BIOS settings once more.
On the new device, I needed to configure the SSD as the main boot device and set it to SATA mode. After restarting, my old system returned (except for the raid drives, which I thought would be lost). On the machine with the old hardware, I had to reset the BIOS to its default settings. Several raid-related options were no longer valid, so reverting back to the original configuration worked.
The lesson here is clear: upgrading a mobo or CPU doesn’t always mean a full OS reinstall is necessary.
