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.
You need to re-install the Grub using the instructions mentioned here:- Grub Install
Afte fixing the boot issue you can go ahead and you can remove Grub by referring the link:- Remove Grub
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.
