Why? I don't understand "Still root device"

[poilpoil]

Hello everybody.
Last week I installed Leopard 10.5.2 AMD EFI Rev.1 in my PC.
After many tests Leopard launched with Vista on same HDD.

But I wanted to fix my bootloader and it didn't work. So I formtted my HDD, reinstalled Leopard then Vista, but now when I want to start Leopard I have the error with root device ?
I don't understand because before this new installation Leo worked perfectly ! (I d'on't change my hardware between this two installations)

Can you explain me why and how to ?

Thanks very much
