Hello fminmexico.
In the part .............mkinitrd-v-f/boot/initrd-2.6.24-desktop-1mnb.img--ifneeded2.6.24.4-desktop-1mnb)
you will notice that 2.6.24-desktop-1mnb and 2.6.24.4-desktop-1mnb are not the same.
I could be wrong but I suspect that during the install process you made incorrect settings in Grub. You could wait for someone with greater skills than I to help you out (this is a weekend of course so could be a long wait.)
I suggest doing a dummy upgrade and and let it setup up grub without your intervention. Would only take about 20 minutes or less and you would be happily on your way. Just on the small chance that doesn't work then a Fresh Clean Install would only take another 30 minutes or so.
Sure you want to learn how to do things in Linux but you can gain that knowledge over time but first you need a working system.
Cheers. John.
