Subject: boot change to /dev/sdc1 but still think it's /dev/sda2


I'm having a problem where I installed an SSD (/dev/sdc1) and even though I have grub set to
root (hd0,0)
kernel /boot/bzImage root=/dev/sdc1 rootfstype=ext4 raid=noautodetect
it thinks my root is /dev/sda2 (my old boot). It is my ssd though (size, contents).

I read that I can try using the uuid:
kernel /boot/bzImage root=/dev/disk/by-uuid/e2647271-08fb-4af5-9a6f-11283a521bbd rootfstype=ext4 raid=noautodetect
My system won't boots bot won't load the kernel that way.

I took a pic of the oops, it's fuzzy but I think it is readable.
