yep, they don't share the same sector. # fdisk -l -u /dev/sda Disk /dev/sda: 146.0 GB, 145999527936 bytes 255 heads, 63 sectors/track, 17750 cylinders, total 285155328 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0008911b Device Boot Start End Blocks Id System /dev/sda1 * 2048 487423 242688 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 487424 285153279 142332928 8e Linux LVM So just ignore this alert? Also, is it still possible to change the end cylinder of the /boot partition without breaking the grub?
