bad magic number fsck.ext2 on /dev/hda1

[chovy]

I partitioned my drives according to the handbook.

/boot was ext2

reiser partition seemed to work, just not boot. something about a "bad magic number while opening /dev/hda1 the superblock is invalid or does not describe a correct ext2"

I mistaken had ext3 in my /etc/fstab but then changing it in "safe mode" and reboot gave it the same error.

I think I didn't run mk2fs earlier on /dev/hda1

I think I really f'd it up now, I re-ran the mk2fs /dev/hda1 now it won't boot up into Grub. says Error 17.

Is there anyway to remedy this, or am I back to square 1.
