I have a Dual Boot with Windows 7 and Ubuntu. Using Disk Management in Windows, I deleted the Ubuntu partition, but when i restart my computer, I'm getting Grub Rescue Command.

I Tried ls (hd0,msdos6) and when I type insmod normal, it says file not found.

This happens when you have faulty or old version of BIOS which can't handle large files. So you need some external third party software to resolve the issue. I would recommend you to make bootable usb for Boot-Repair or Rescatux(I recommend this).You can easily find them by searching. A link from sourceforge for boot-repair https://sourceforge.net/projects/boot-repair-cd/ and Rescatux https://sourceforge.net/projects/rescatux/ They may help in fixing the lost grub path or installing a new grub if you want.
