I'm trying to create disk image with 2 partitions: First partition: 1Mb for boot and second partition of the maximum capacity

  dd if=/dev/zero of=flash.img bs=1M count=10
  /sbin/sfdisk flash.img -uM << SFDISK_EOF
,1,L,*
,,L;
SFDISK_EOF

I got an error:

sfdisk: I don't like these partitions - nothing changed.

What I'm doing wrong?

I'm working with CentOS

    Might be simplest to use regular fdisk to partition the image once manually, and then use sfdisk -uM -d to dump the partition info into a file or standard output. The dumped output may highlight a critical error in your commands. – Mike Renfro Jun 18 '11 at 18:17

it's 2011, why don't you use something more user-friendly like cfdisk? I've used sfdisk once a time in a bash script for an automated OS rescue system, not on ordinary system administration.

  • the cfdisk is not part of the CentOS distribution, this is the reason why I'm using sfdisk. Anyway, I increased image size and problem is gone... – Dima Jun 19 '11 at 22:53
