    Hi,

    this error might occur due to many reasons. Please try the below steps to solve the issue.

    access BIOS to check if your boot device is detected or not. during power up press F2 to access BIOS. under information look for HDD. if HDD shows as none or blank then the HDD is not detected if it shows Serial number then its detected. 

    Now go to the tab called BOOT and check the boot mode. if the boot mode set to UEFI then you can press F9 to set the BIOS to defaults and continued by F10 to save and exit. If the boot mode is set to legacy then change it to UEFI and continue with F9 and F10. if the issue does not resolve then try the below steps.

    during power up press and hold Alt and keep tapping F10 to access additional options. here click on troubleshoot > advanced options > you can select system restore to restore your unit to an earlier date & time. if this does not solve then you might have to reload the operating system by choosing reset this pc under troubleshoot.
