When you switch on your system, the boot manager loads the operating system into the system. This error is probably because the boot manager is unable to load the OS into the system.

Here are a few methods to solve your problem:

Method 1: Uncheck “Compress this drive” option.

The error being caused by a compressed hard disk, it is possible to fix it by disabling the data compression. Follow these steps to uncheck “Compress this drive to save space” that is applied to the hard disk.

  6. Right click on C: drive and then select Properties
  7. Open Advanced tab
  8. Uncheck “Compress this drive to save space”
  9. Restart the computer
