How to fix the error "no boot disk has been detected or the disk has failed"?

Question

Windows

I decided to put Windu on the ssd, booted from a bootable USB flash drive with Windows, formatted the old HDD disk, chose SSD for installation, the installer created the necessary partitions, wrote that everything was successfully downloaded, and rebooted the computer where I get the error "no boot disk has been detected or the disk has failed" did this several times already, the boot is always successful SSD BIOS also sees, while there was no Windows on the SSD, it also worked without interruption, HP computer, Legacy Support turned on, boot priorities set, when Secure Boot was turned on, the error "boot device not found please install an operating system on your hard disk", from this flash drive I recently loaded Windu on the HDD, everything worked, now that I load it on the SSD, that everything is the same on the HDD. It's been 2 days I can't figure it out. Please help, SSD - Kingston SA400S37120G

Answer 1

Disconnect the HDD and put it on the SSD again, it will be faster than restoring the bootloader.
