As Mark wrote, first format /dev/sda1 using mkfs.ext3, mkfs.ext2, mkfs.reiserfs etc. - whichever filesystem you use(d) - and then mount it as /boot.

After that you have to reinstall your kernel image(s) because this is what you have essentialy wiped out. The install scripts in the linux-image-* packages should then automatically recreate GRUB's configuration.

Good luck!
