Hello,
Reboot your machine and when the Boot Menu flashes up - select
"Microsoft Windows Recovery Console"(you need to be very fast with the arrow key as you only have a couple of seconds before it defaults to the windows XP bootup)
When you get to the above screen, take note of the number that references your operating system.
If it's
'1' like the picture above, type
1 and press
Enter Next type
FIXMBRIf it ask if you're sure you want to write a new MBR, answer
'Y'Then type
EXIT to reboot the machine.
Let me know how that goes.
Also run a new scan with MBRCheck and post the log. I'd like for you to run it normally (double clicking on it and letting it run).
Post the log from it in your next reply, as well as an update on how things are currently running.
