HFS_mountroot failed 5

[esz]

Hi,

i have installed iDeneb and got after the boot from HDD a waiting for root device error. I formated the disk and wanted to install with a different configuration.
But after the format the setup don't show. I got the HFS_mountroot failed 5 error. I have formated in any way with almost every software and i got still this error. why it don't work any more?
I think it's the MBR or something with the HDD. What can i do?

Please help. It was almost installed.
