Yesterday, I resized the boot partition on my sles 10 zcm server and got the GRUB error 18 when I restarted. It's a vm, so I reverted to a working snapshot, but I need to try again.

Here's the fdisk result for sda:
Disk /dev/sda: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 1 262 2104483+ 82 Linux swap / Solaris
/dev/sda2 * 263 1305 8377897+ 83 Linux
/dev/sda3 1306 2610 10482412+ 83 Linux

Here's the current free disk space:
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 8.0G 7.2G 862M 90% /
udev 1015M 104K 1014M 1% /dev
/dev/sda3 10G 33M 10G 1% /zcm

I don't need /zcm anymore because all the zen apps, etc are on a different partition, so I blew it away and added the free space to the root partition using gparted. What did I screw up? Thanks.
