The error "DISK BOOT FAILURE - INSERT SYSTEM DISK AND PRESS ENTER" "No boot device available, press Enter to continue" means that the BIOS is unable to read the designated boot disk. This can be caused by a corrupt hard drive, damaged hard drive, or a faulty data cable. One way to troubleshoot a boot disk error is to insert a bootable Windows Recovery USB drive and reboot the machine. From the Windows Recovery menu, select the Command Prompt option. In the Command Prompt, list available disks using the command `wmic logicaldisk get name`. Run `chkdsk` on the suspected bad drive to attempt a disk repair. For example, if the C: drive is suspected to be faulty, run `chkdsk /r C:` in the Command Prompt, hit Enter, and hit Y if prompted to continue. This process may help diagnose the issue, but it is possible that the drive may require formatting and reinstallation of the OS if the data is corrupted.
