i've installed sqeeze (amd64) and grub2 as the boot loader.

Since grub2 is installed on the mbr no way to boot my lenny system.
Here is the lenny part on grub.cfg:
menuentry "Lenny, kernel 2.6.28_mm01 (on /dev/sdc6)" {
    insmod ext2
    set root='(hd2,5)'
    search --no-floppy --fs-uuid --set f26b56c1-4550-4815-b7bf-e5f114c6f9e4
    linux /vmlinuz-2.6.28 root=/dev/sdc6 ro quiet vga=788
    initrd /initrd.img-2.6.28

UUID is disabled as default.

What does "no way to boot" mean?

Is Lenny's /boot on sdc5 or sdc6?

It mean's i can't boot lenny. /dev, /proc, etc.. couldn't be mounted ( a
common error message encountered , now and in the past, when a root dir
isn't found)
The Lenny-root is on sdc6 ext4. The /boot partition is on sdc5 ext3.
So grub is loading your initrd and the latter cannot mount your
partitions, probably because you are using sdc6 instead of hdc6 or
because Lenny is recognizing sdc/hdc as sda/hda or sdb/hdb.

blkid /dev/sdc6
Change your linux line to
linux /vmlinuz-2.6.28 root=/dev/disk/by-uuid/<output_of_blkid_above>
ro rootfstype=ext4 vga=788
linux /vmlinuz-2.6.28 root=/dev/hdc6 ro rootfstype=ext4 vga=788

Ok, i don't know what happen exactly but the UUID is completely defferent between grub.cfg and the
'blkid /dev/sdc6' results: UUID="7057a48b-9ed1-4c6d-bb02-5822dddd8b06" TYPE="ext4"

So i changed the uuid but still the same error and a busybox and initramfs.
No boot.
Can it be a bios problem or a GRUB bug ?
