so, i recently installed ubuntu to check out the advances in the linux world since i last looked into them 10+ years ago... very impressed, but when i tried to delete ubuntu and remove the various partitions (which i was able to do just fine using gparted) reFIT still displayed the damn linux logo from the install i deleted....

this is frustrating...

so i went in and looked around with the remaining partitions and noticed the EFI partition which hadn't shown before i mistakenly tried to install another distro over ubuntu after wiping the partition it was on...

so i erased the EFI partition hoping that this would remove the g-damned hold out linux boot logo in reFIT... it didn't... now i suppose i can go back in and create a new EFI partition through gparted but that stupid linux logo will still be there... and i'll have another problem of getting the proper information back onto the EFI partition, which i am unsure of how to do, or where to even dig up the proper information...

i want to edit my boot mbr or grub or whatever the eff apple comps use as a boot record so that (or i am using as a boot record since i'm using reFIT) to get rid of this damn logo, so i can install another distro of linux and probably windows without having the damn supernumerary logo...

i would rather not wipe the whole drive (aka the primary partition the recovery partition) and do a fresh new install of os x (mountain lion) because i have OSX set up just the way i want it for personal use and work use... all my various tools and so on...

i don't use time machine and can't do a "restore" from a previous back up...

some one please help me out here, what are my options? am i going to have to bite the bullet and do a wipe of the entire drive and all its partitions to get my MBP back to 'normal'???

PS - using a macbook pro late 2011, standard specs, 13"...

rEFIt installs in your OS-X partition from memory.

It will be in /efi/refit in your Macintosh HD partition.

You can delete it (the /efi directory and all contents).

Probably best to follow these (http://refit.sourceforge.net/doc/c1s3_remove.html) instructions - try the manual method.

Deleting your EFI partition is not so good. It has a special partition type code I think.

Use Disk Utility in Ubuntu or Mint or whatever, to recreate it: Type EFI System Partition. Mine has a label which is also 'EFI System Partition'.

Apple does not seem to use it in my case, so leave it empty. I don't know what other OS-X versions do with it.

In future, don't bother with rEFIt, or use rEFInd - they are both no longer required in my experience. rEFInd is much better in my opinion.

But do install grub-efi and remove grub-pc.
