Windows doesn't find the old hard drive.
Windows doesn't find the old hard drive.
The information suggests it's an older system, with the HDD typically located under the UEFI area. I assume it might be a motherboard problem since the boot sequence isn't showing up. The drive uses GPT and NTFS formats.
It seems the setup didn’t show up as GPT, but I think I selected GPT during the installation. After checking DiskPart, it shows it’s not GPT—maybe there’s an issue. The good news is it looks like a fix is possible without losing any data.
Yes, it's possible to achieve this without losing any data. I used the provided resource: https://learn.microsoft.com/en-us/window...mbr-to-gpt
Thanks for sharing the details. Here’s a clearer version of your message:
You successfully converted the SSD to GPT format. Now the drive appears in both legacy and UEFI systems. You also observed that clicking "load defaults" in BIOS restarts the system, recognizing the HDD until you restart again, after which it disappears and needs redoing. A new SATA connector didn’t resolve the issue. You’re considering a future upgrade of the motherboard and CPU, wondering if that would fix the problem or if there’s an underlying issue with the HDD. Thank you for your patience.
You can reinstall Windows 11 on an SSD, which may allow you to view your HDD again.
