Vista HP on notebook won't boot

[in-somniac]

Hi All!

I'm having a problem with a Toshiba Satellite A300 notebook at the moment. It won't boot past the Vista Loading screen in either normal or safe modes. I have tried a startup repair from the Vista disk but it says there is no startup problem to repair.

I took the hard drive out and attached it to my desktop (via an external casing) and ran MalwareBytes and AVG scans.

MB found:
adware.rabio
Trojan.HostsfileMod
Trojan.Agent

AVG found:
Win32/Heur

Am I correct in my understanding that none of these infections should render the pc unbootable?
I have since put the hard drive back into the notebook and still have the same problem. I have tested ram, cleaned and reseated the CPU and heatsink, and am currently running a chkdsk /r from the cmd prompt option from the Vista disk.

Any other ideas??

you can try fixing the master boot record

1. Start your computer from the Windows Vista Installation DVD
2. Press a key when prompted to continue
3. Choose your language, time, keyboard and click Next:
4. Next, click "Repair your Computer":
5. Now, from the System Recovery
Options dialog, select the "Operating System" you want to repair, then click Next
6. From the "Choose a Recovery Tool" dialog menu, select "Command Prompt":
7. Type the following into the "Command Prompt Window":
bootrec.exe /fixmbr
bootrec.exe /fixboot
8. Remove the Vista Installation DVD and restart your PC.
