iDeneb 1.5.1 on T61 strange error on bootloader

[lukenukem]

After a lot of fail to install iAtkos on my T61, I try to install the iDeneb distro.

In the first try installation I take some errors and the installation fail. The error seems to be on the bootloader (Chameleon v2) post installation activity.
I try to install it on a HD totally dedicated (with only 1 partition) to OS-X.

To bypass I create 2 partition, I select Chameleon v1.0.12 and use a FIX cpu and install iDened on 1 partition. With this option the installation finish sucessfully.
After this step I delete the 2 partitions, recreate only 1 (the original situation) I use the default bootloader (chameleon v2) of the distro (Fix CPU on) and now the installation works fine.
Anyone knows the reason about this strange situation?

I see in some post around this forum that a lot of people is usually to install iDened on a dual boot system...any experience about full HD partion for iDened? Anyone has the same errore?

Now my T61 works with iDeneb 1.5.1 with 1024x768 , Eth connection , and standard USB mouse...I will work for the next steps

Ciao
