GRUB is a bootloader: it's sole purpose is to boot your kernel from the hard disk. You should try reading the GRUB documentation, it's not obscure.

Among the good things about GRUB is that it will boot your kernel, your development platform, and your Windows install (for playing games) all from the same hard disk.

I have Every File Needed to Boot My Kernel. can any one explain me how to boot into it.

i would me more happy to boot from my Kernel from Harddisk
and that too using Grub as a boot loader.

The best solution is to write a loader witch will be loaded with GRUB, then will load all files needed by your OS

If you want to know how to use GRUB, this link may be useful

Add grub multiboot header . Compile your kernel and boot it....
See OSD samples:

I dont even use a bootloader...
I just use PARTCOPY and copy the binary file into sector 0.
this would work for your hd, but it would destroy your current boot sector!
I'm new to OS programming someone tell me if i suck...

Jonny, sector 0 is the boot sector. When you use PartCopy to write to sector 0, you are basically putting in your own code for the boot sector. Not really destroying (unless you already have another system installed). Sector 0 is the boot sector for both the floppy and the hard drive. So your system would work on both a floppy disk and a hard disk.
Oh, and, you don't suck. You are just new to programming an operating system.

If you need to load multiple files, why not use GRUB's built-in module-loading capability? Much simpler than creating a loader for GRUB to load.
