Error loading operating system

Specs: Windows 10.03.2010
Intermittently I receive this message & can proceed no further; more often I boot from the full Vista disk, I then choose to boot in Safe mode, all the Windows 32 files load, then "Please wait" appears at the bottom of the screen and the laptop (Toshiba) sits at this point & can proceed no further. I had a recent issue with this laptop (10/2011 posts on this site), and like that this happened after a restart following a Malwarebytes' scan. Partition issue?

Test the hard drive with the drive manufacturer's diagnostic software for DOS.
The links are here:

The DOS version is an ISO file from which you can make a bootable CD using IMGBurn from here:

Boot your faulty PC from that CD to test the hard drive.
If it passes the test it must be something else so try re-installing Windows or doing a factory recovery.

If it fails the test you will need to buy a new hard drive.

Ran Seatools for DOS on the Toshiba; detected 1 device (identified the HDD accurately after running the diagnostic test) and no errors.

Re. attempts to reinstall Windows, I have on recent attempts been able to get a screen which offers F8 option, then I get the option for Start in Safe Mode, Command Prompt, etc.. I chose Start w Command Prompt, then received the original result of all Windows files loading then stalling at "Please wait..."

Ran Avira Antivir rescue scan on Boot Sectors Only. This shows two warnings:
[IO error on file]Master boot sector (disk/dev/sr0)
[Error reading file]Boot sector (/dev/sdal)

The Avira Rescue scan on All Files stops after scanning 260 files, 81 directories. Internet connectivity should be possible but Avira indicates that it is not (re. updates). No problems (0 infected, warnings, suspicious) detected.

Is this pointing to a faulty/missing partition, or a mainboard problem?
