I tried to fix the FC2 linux with the gentoo live CD, because it stopped by activating the swap. So i made the swap again and i accidentaly type mkswap /dev/hda1 instead of /dev/hda2, now the /boot partition is gone

Then i made the mkfs.ext2 /dev/hda1 and now there's only lost+found folder on that partition. I didn't make any other changes on that partition, so data shoul be intact on it, so how to recover it ?
The FS before was ext2. Maybe if i just copy the kernel images and reconfigure the boot loader it would work the same right? The problem is that i dont know where the kernel images are
