WINDOWS Boot Managerthe windows failed to start. A recent hardware or software change might be the cause. To fix the problem

try safe modewhen starting up by tapping F8every second or so until the start up options menu appears .
If you can get into safe mode we have progress.

Might be a virus causing it

Do this first - if it doesn't bring up the boot menu options first time, shut down and re-try - you need to keep tapping the F8 key as soon as you turn it on. Choose Safe mode with networking when the menu appears.
What you do next depends onwhich version of Windows you have - is it Windows 7!

Yes it is windows 7

Hi we can get safe mode with networking what do we do next please!

I would start by running virus scans

first with this http://support.kaspersky.com/5350!el=88446 click on option 1, download and runThen do the download, update and full scan with http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html

Essentially we now know that one of the startup items must be be causing the fault and virus scan is always a good place to start

UPDATE We have done all of this and first option picked up a trojan and second full scan picked up 37 issues.
After doing these two scans computer now starts up as it should.
My question now is it fixed! Or do we still have to do something else! and if it is now fixedthankyou so much we really appreciate it
