Windows 7 does not Boot , error : Drive does not exist

[SDK7]

I have Windows 7 and Ubuntu in my Lenovo laptop
And couple of days back i wanted to format the windows partition , and in the recovery environment thing , there was something wrong , and i ended up deleting the 200 mb partition of Windows , I think which contains the OS files ..

Now my Windows 7 wont run , its simply gives an error page :
Error : Drive does not exist , ( a 20 lettered hexadecimal thing here )
Error : Disk not exist

Is there anyway i can recover my Windows 7 ?
I can still acces the Windows Recovery mode , as it is an option in the OS selction , but it leads me to a DOS like terminal , in which i do not know any of its codes .

Help Please ?

YES, but you will need to reinstall Linux boot loader, after repairing windows.

   Information

We always assume you have made your Recovery Disks using the OEM manufacturer's app the first day you had your new PC.
& made the Startup Repair CD.
startup repair disc-create
​

   Information

Boot up using the Startup Repair CD or Windows 7 DVD. (not the OEM manufacturer's Recovery Disk) If you have a Netbook, you will need a CD/DVD drive.
NOTE: Make sure no USB drives are plugged in.
Do not use a USB Pendrive for Startup Repair.
