Hi Aixa,
The Non-system disk or disk error usually occurs when the
computer is unable to find an operating system on any of the storage devices. When this happens, the computer won't be able to load your
Windows operating system. To determine what's causing this issue, we'd like to ask a few questions:
- Have you made any recent changes to your computer?
- What is the make and model of your device?
- What steps have you done so far to resolve your concern?
We're looking forward to your response.
