have you compiled and installed the kernel 2.6.30.5?
the last step is make install and that should give you a new entry in the grub.
hope this helps

An entry in the file /etc/grub.conf can solve your problem. Here's an example of it:

Code:
#boot=/dev/hda
default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.6.6-1.435.2.3)
        root (hd0,0)
        kernel /vmlinuz-2.6.6-1.435.2.3 ro root=LABEL=/ rhgb quiet
        initrd /initrd-2.6.6-1.435.2.3.img
title Fedora Core (2.6.5-1.358)
        root (hd0,0)
        kernel /vmlinuz-2.6.5-1.358 ro root=LABEL=/ rhgb quiet
        initrd /initrd-2.6.5-1.358.img
title UML Vanilla (2.6.7)
        root (hd0,0)
        kernel /vmlinuz-uml ro root=LABEL=/ rhgb quiet
        initrd /initrd-2.6.7.img

Just add your custom entry at the end beginning with

Code:
title My Kernel
When you restart your system you should see your kernel listed in the OS/Kernels list. Select your kernel and see if you succeed. If not, then post the contents of your grub.conf file with the modifications you make in it.

As to booting from a USB stick, this is accomplished with your BIOS, not the Grub configuration on your hard drive. You have to enable USB booting, and you have to give the USB boot device priority over the hard drive.

As to the location of the grub configuration file, it is located at:

/boot/grub/grub.conf
