Non system disk or disk error
My PC has been working just fine for about 4 years but yesterday I went to switch it on and I get 'Non system disk or disk error replace and strike any key'
Searching online says this is an issue with my operating system, but any ideas on what to do to fix this would be appreciated.

The "Non system disk or disk error" message typically indicates that your PC is unable to find the bootable operating system on your drive. Since your PC was working fine for years and suddenly shows this error, it could be caused by several issues such as boot order changes, a disconnected or failing drive, corrupted boot files, or issues with the disk itself.
