My machine has been working fine. All of a sudden, when I restarted the machine, it did a hardware check and responded that the hardware was fine but could not find the boot bios. How do I fix this issue? When I now turn on the machine, it immediately says boot device not found “Press continue to turn machine off”
Sometimes Windows Updates can corrupt the boot management and a repair is needed.
What computer is this? (desktop, laptop, branded, etc)
During the hardware check, did it test the hard drive? If so, and the drive is OK, it may be Windows file corruption. If not, try to determine the HDD manufacturer and download their drive diagnostics (both Seagate and Western Digital have fine diags) and run that to test the drive. Typically that message indicates that either the drive has gone south or the Windows files have become corrupted.
