Deleted ubuntu, deleted GRUB, HELP!?

I'have installed ubuntu, windows and linpus, and all correct with grub, but, I deleted the partition of ubuntu because I install osx.
When the machines boots, first show darwin bootloader, and I can select windows or mac, if select windows, apear the typical boot.ini with Windows or Grub. But when I select grub, black screen and nothing more...

How can acces to my linpus? can reinstall grub?

 

boot a LiveCD, go into the grub files and reassign the drive partitions, making sure the boot choice actually reflects the partition you want. search for repair grub either in the forums or google, either will get you your answer.

 

when i boot with linpus says:

Try (hd0,0): extended or non-MS: skip


EDIT Error 15: File not found
with supergrub, i read the configuration
"rootnoverify (hd0,0)
Kernel /boot/bzImage ro root=LABEL=linpus vga 0x311 splash=silent loglevel=1 console=tty1 quiet nolapic_timer
initrd /boot/initrd-splash.img

Can someone upload your boot?

 

The only way I was able to fix dozens of my GRUB problems in the past, was to reinstall the OS. Thats the only way it worked for me.

 

In relevant part:

Essentially, hd0 is your main drive

hd0,0 is the recovery partition. ignore it. GRUB calls anyone non-ext# a windows partition.
hd0,1 is your first partition, in my case vista
hd0,5 happens to be where my ubuntu is installed, just b/c of the way i partitioned things out (separate partitions for swap and home
