                         Legacy support or UEFI Mode, which is right for run win 10

I do not have a HP Laptop to demonstrate that error.

But here is the fix that should solve your issue.

1. Try Enabling the "LEGACY" option in the BIOS and Disable Secure Boot. (Worth a try)

2. Hard Drive is Bad or Failing.

3. Partition Table is corrupt and needs to be wipe and rebuilt ie: Reformat Machine and reinstall OS with HP recovery discs.

4. Hard Drive data cable that connects it to the motherboard is bad and needs to be replaced.

5. SATA Controller on the motherboard is bad or failing. Repair if possible or replace motherboard.
