I am running Windows 10 on an HP Pavilion desktop, and the system has been quite stable since installing Win 10 (upgraded from a stable Win 7) until the past several days when booting up past the initial screens with BIOS info brings the message: MBR not found, insert System Disk, restart computer. I believe I understand what this message means. Of course, I have no System Disk to insert, etc. However, if I force a total power shutdown and then restart in a few minutes, the bootup routine proceeds as expected, that is, Windows loads and the computer behaves normally. This has worked every time the issue has appeared.
Does this suggest my hard drive is about to fail? I have been careful to keep a complete backup of documents, pictures, etc. on the drive and periodically use EaseUS Backup to create an image to restore Windows so I am not in panic mode - yet.
The drive has been in use almost daily for half a dozen years or more, and until now I have had no reason to suspect any operational problem. Might it help to run a disk utility from Seagate or another source? The HD is a Western Digital, as I recall.
Thanks for advice.
