Archiso and partition

Hi all,

I'm following this guide to build a custom Archlinux installation. I've used the "baseline" approach and I've modified the build.sh to customize some stuff. Now I'm trying to figured out how to generate the iso file that has not only one partition but 2. At the moment the only way to get 2 partitions in the usb stick is to manually add after the copy with dd ( e.g. fdisk /dev/sdc ). I've tryed to open the iso file with fdisk but with no luck :

root:~campo/System/archlive]# fdisk out/archlinux-2015.04.23-x86_64.iso

Welcome to fdisk (util-linux 2.26.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

To create more partitions, first replace a primary with an extended partition.

Sorry for the italian. Can I switch from primary to extended ? I guess it could be a problem for the bootloader but I'm not sure. Does anyone know a a way to add the partition ?

*Just an update

I've tryed to add a partition after dd to the USB stick and Windows doesn't recognize enyithing ( of course ). What I want is a partition that could be written by windows and linux. Is there a way to do that ? I've read that windows can't handle more than one partition in a usb.

Re: Archiso and partition

Use this method to create the bootable USB stick:

This uses an FAT32 partition, so it can be written by windows as well.

Re: Archiso and partition

It doesn't work. I think the problem could be isolinux. Or maybe the strabge filesystem of the iso. The partition is

When I try to mount the usb stick in my system, after dd, the filesystem is read only.

Re: Archiso and partition

Please follow the instructions in the wiki exactly. Otherwise no one can help you.
For example, use cp instead of dd...
