Boot Manager missing at boot.

Hi all,

Forgive me if something like this has already posted, but i couldn't find anything.

I have been trying to install another partition on my drive C:

As I went through the wizard, it went through the procedure of installing the partition and then said it needs to boot to continue the operation. After it rebooted, it came up with boot manager missing and now my windows 7 will not load. Nothing I do will make it load up. I have tried doing a repair from the windows 7 Pro DVD but it says there is no operating system. What has gone wrong with it. I wanted the new partition for doing fresh install of windows 7, so I don't have to use the disk.

Just to point out, I have just built a new system -

Gigabyte - GA-970A-D3
AMD PHENOM 965 X4
4 Gb RAM
SEAGATE 500 Gb - ST500DM002

Forgot to mention I'm using Hard disk manager12 suite

Any help would be most appreciated, ASAP.

Tony
