What is the correct process to install to a HDD? I used: sudo dd if=ZeroShell-2.0.RC3-IDE-USB-SATA-Disk-2GB.img of=/dev/sdh then set the boot flag for the first partition. (/dev/sdh is my usb key) January 26, 2014 at 9:31 pm #53137 imported_fulvioParticipant Hi, the Install Manager makes the installation on disk (also USB Flash) much faster and easier. To use the Install Manager you need Zeroshell 3.0.0 with the package 30200 installed. Regards Fulvio January 26, 2014 at 9:44 pm #53138 sballMember The correct way is: dd if=/path/to/image.img of=/dev/ bs=1m So, try bs=1M or bs=1m after the command you tried earlier 🙂 Also, if you’re on OSX, use /dev/rdisk instead of /dev/disk, since that will be a lot faster.

It would make it faster I am sure, but making a difference… I am not that knowledgeable about dd 🙁 Thank you guys!

I have not had a chance to use install manager as I tried with a drive that was created via dd and it could not use it.
