Hard disk replacement (partition not found)

[H3li03]

Hi there guys, I was able to upgrade the zif hdd to a compact flash (64Gb)!
It does work with the official firmware after formatting it to a primary partition without issues, and the extra GB are recognized!
I wanted to install rockbox again, but the daily and the stable version do not work, it launches but prompt a error with (partition not found warning)

Any help?
Thanks
