No problem, i'm busy too and as you can boot i've been delaying posting.
Also you didn't mentioned were do you have the booter installed or if you did tried the booter with embedded theme?!
When you have time to provide those, i'll come back
without those i'll be only speculating...
p.s.: well, thinking a bit...
if you have Chameleon installed on disk0s2 and you have a Themes folder (with themes) on Extra on that same partition, then
either disk0s3 it's letting Chameleon confused in some way!? Same for Chameleon installed on EFI partition and Themes folder on it. This is using the RC5 without embedded theme.
What type of file system do you have on that Microsoft Basic Data partition?
I have the same type of install as you; GPT HD, Chameleon RC5 installed after EFI partition with boot0+boot1h;
checking with GParted, EFI partition shows as Active; Themes folder, no theme embedded and i have none of the problems you mentioned.
But, foreign partitions are banned from my GPT HD
they break all the nice things that can be done with hfs+ ones; only
do them on GPT for testing purposes!
The bottom line is, the booter
only checks for themes on the partition were is installed so, if you use the no theme embedded RC5 "boot" file, a Themes folder on the the booter partition and you get no Gui, the booter is looking for themes else were.
Anyway, i need confirmations, otherwise i'm just speculating.
p.p.s: It seems i've been saying some bs! I went deeper on the booter code and it does check selected volume for themes.
I also found support for Microsoft Basic Data partitions. Still, weird stuff is happening with some partition configurations/layouts.
Sorry about the bs
