Comment on grub2 cannot read core.img by chutz

@cmh: You can do it with fdisk, but you should tell it to use sectors as a unit. Either start fdisk as “fdisk -u”, or type “u” once you are in the fdisk interface. Then delete the partition and create it again (you will of course lose all data on the partition). A snipped down fdisk session:

$ sudo fdisk /dev/sdb Command (m for help): p … Device Boot Start End Blocks Id System /dev/sdb1 * 1 3011 3915204 b W95 FAT32 Command (m for help): u Changing display/entry units to sectors Command (m for help): p … Device Boot Start End Blocks Id System /dev/sdb1 * 1144 7831551 3915204 b W95 FAT32 Command (m for help): d Selected partition 1 Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First sector (51-7831551, default 51): 63 Last sector, +sectors or +size{K,M,G} (63-7831551, default 7831551): +1G Command (m for help): p … Device Boot Start End Blocks Id System /dev/sdb1 63 2097215 1048576+ 83 Linux

how do you destroy the first partition and recreate it from sector 63?

Thanks for posting this information. This helped me with my long-standing problem. Grub2 despirately needs some basic technical documentation, including common issues like this one. So sad that it is so neglected, since it is so important.
