OK you have a bad partition that needs removing
Download Tuxbot (http://sourceforge.net/projects/tuxboot/files/latest/download?source=files) to your desktop
Run Tuxboot
On the first screen in the dropdown box select Gparted Live - stable
(https://dl.dropbox.com/u/73555776/Tuxboot.GIF)
Select USB Drive from the Type drop-down.
Select the correct USB device from the Drive drop-down.
Click OK. This will start the process of creating the bootable USB device.
Now boot off of the newly created Gparted USB.
You should be here... Press ENTER
(https://dl.dropbox.com/u/73555776/Gpart-Start.GIF)
By default, "do not touch keymap" is highlighted.
(https://dl.dropbox.com/u/73555776/Gpart-keyselect.GIF)
Leave this setting alone and just press ENTER.
(https://dl.dropbox.com/u/73555776/Gpart-continue.GIF)
Choose your language and press ENTER. English is default [33]
At the mode prompt enter 0, press ENTER
You will now be taken to the main GUI screen below

The Partition has gone

Select Apply after double checking that the right partition was deleted
Is "boot" next to your system drive (100MB)?
If "boot" is not next to your system drive (100MB) under "Flags", right-mouse click the OS drive while in Gparted and select Manage Flags
(https://dl.dropbox.com/u/73555776/GPart-flags.GIF)
In the menu that pops up, place a checkmark in boot like the picture below, then close :

You will see this small Popup
(https://dl.dropbox.com/u/73555776/Gpart-reboot.GIF)
Choose reboot and then press OK.
Reboot to normal windows, if windows gives an error then select startup repair
-
so i did everything as you said and the start up repair wasnt able to automatically fix it. it just loops at start up then back to the repair
-
Could you confirm that you set the Active(Boot) partition to the 100MB system partition
1 - [XXXXXX] NTFS (0x07) [VISIBLE] Offset (sectors): 18866176 | Size: 100 Mo
-

OK that is weird.. Using Gparted set the boot to the main system drive 456Gb
-

Could you try a further startup repair from the recovery console
-

-
When you did the first startup repair did you do it from windows or the recovery console ?
Could you attach a fresh OTL log please to ensure that it has all gone

Subject to no further problems :)
I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems
Now the best part of the day ----- Your log now appears clean :thumbsup:
A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:
Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.
We will now confirm that your hidden files are set to that, as some of the tools I use will change that- Click Start.
- Open My Computer.
- Select the Tools menu and click Folder Options.
- Select the View Tab.
- Under the Hidden files and folders heading select Do not show hidden files and folders.
- Click Yes to confirm.
- Click OK.
(http://users.telenet.be/bluepatchy/miekiemoes/images/javaicon.gif) Your Java is out of date.
Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.
Upgrading Java:- Go to this site (http://java.com/en/) and click Do I have Java

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:
(http://img233.imageshack.us/img233/7729/mbamicontw5.gif) Malwarebytes (http://www.malwarebytes.org/mbam-download.php).
Update and run weekly to keep your system clean
Download and install FileHippo update checker (http://www.filehippo.com/updatechecker/) and run it monthly it will show you which programmes on your system need updating and give a download link
It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit - Microsoft Windows Update (http://windowsupdate.microsoft.com)
To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ? (http://www.geekstogo.com/forum/topic/225044-preventing-malware-and-safe-computing/)Keep safe :wave:
