Windows 7: bootmgr is missing in windows7home premium in dell inspiron15R-2106SLV

Hi
I bought a new dell inspiron15R-2106SLV and when i am doing some changes in disk management i found error like Bootmgr is missing Press CTRL+ALT+DEL to restart

I am unable to use my lappy as its not going into OS side..

So someone help me on this issue what to do next by step by step procedure.

Thanks in advance..

What changes did you make in Disk mgmt? Did you change the Active partition without knowing what you're doing? This would make it unbootable.

If so mark Windows 7 or its 100mb System Reserved partition Active: Mark Partition Active

If it doesn't start then, run Startup Repair - Run up to 3 Separate Times
