Can the E/E folder in the hidden EFI partition which is formatted as FAT32?

I was unable to dual boot Vista after I put the E/E folder in the hidden hfs+ EFI partition.

You will need this tutorial:

and this tool, called gptsync:

Read it very carefully, it did work for me, so it should work for you too.
Now I have a triple boot SL 10.6.2 / Ubuntu Karmic Koala / Win 7 Ultimate 64 box. Yay! :)

I have boot1h, boot file, /Extra/Extensions/ and all the necessary files on my EFI partition, formatted HFS+. My SL partition is completely untouched, vanilla. And more what's important, it even works! :D

In theory, Chameleon should also be able boot from with the EFI partition formatted FAT32 (like it does from some FAT32 USB keys), but it's NOT recommended. There will be limitations, like: In FAT32 you won't have *NIX-like file ownership and permissions. The permissions on your kexts will suffer, and you won't be able to (re)build an Extensions.mkext there. You'll be much better off using HFS+, non-journaled. That way, if anything breaks (really badly), you'll still be able to mount your HFS+ EFI partition with read&write permissions from a Linux live CD like Ubuntu or Knoppix, or the Parted Magic linux USB stick, in order to make the necessary editing and corrections.

Hope this helps. Good luck! :)
