What happened to running the Windows AIO tool King Quiambao, it is important when troubleshooting that you follow the steps and post back with any outcome, not doing so and trying things not suggested can end in disaster
Is the HDD detected in the BIOS, a Seagate HDD will begin with the letters ST and a Western Digital HDD will begin with WD, other brands vary and please note that any mention of a HDD in the BOOT sequence that is not labelled with such letters is only the boot order and not the BIOS detecting the presence of a HDD, see example attachment;
Edit by phillpower2: Just looked at the Speccy report in your malware thread, a clean install would definitely be your best option as you have a whole load of stuff on the HDD that shouldn`t be there, Avira when you are using Windows Defender and ASUS touch pad drivers on a Sony Vaio etc, your HDD looks ok so the problem most likely Windows related.
If your computer will not boot from the USB ISO you may have UEFI BIOS and need to disable secure boot, canned steps for this below;
If your computer will not boot into Windows at all, power up or restart the computer continually tap or hold down the key that will allow you to access the BIOS on your computer and then do the following;Select Security -> Secure Boot and then Disabled.Select Advanced -> System Configuration and then Boot Mode.Change UEFI Boot to CSM Boot.Save the changes and Exit the BIOS, commonly F10.
