Hi Ninny,
thanks for your help.
Here's what I get without using the initrd:
VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Please let me have your considerations.
Thanks again,
Andrea
