Hi:
If Windows is installed in EFI mode, you can't change the BIOS mode to Legacy because it uses a different hard drive partition table (MBR), and the GPT-formatted drive can't boot.
Run the F2 hard drive diagnostics test and see what it reports.
If the drive passes, then you can reinstall Windows, but I would select the EFI USB flash drive to boot from, not the Legacy one.
Your notebook was designed to run in EFI mode with Secure Boot enabled.
Be alert for scammers posting fake support phone numbers and/or email addresses on the community.
