I don't mean to be cynical when i say this: with all the brains out there, you would think someone could have figured this out before and made a post about it. So, here I am making a post about it. Let's get to business.
The general steps are: - Format the drive in FAT32.
- Copy the install and isolinux folders from the ISO image to the thumb drive.
- Rename the isolinux folder to 'syslinux'.
- Rename the 'isolinux.cfg' file in the new 'syslinux' folder to 'syslinux.cfg'.
- Run syslinux against the USB drive to give it a boot sector and make it active.
- Copy the Zentyal ISO image to the thumb drive.
- Boot from the thumb drive. Let it fail and bring you to a 'boot:' prompt.
- Press Enter to begin the setup process.
- At the part where it can't find the CD-ROM device, tell it you'll specify the device manually.
- Use an alternate terminal (Alt+F2) and mount the USB drive.
- Return to the setup process (Alt+F1) and enter the path to the ISO image on the USB drive.
- Continue setup and rejoice in your recent accomplishment.
Note: When it asks to dismount other mounted volumes tell it Yes. It won't break like you think it will.
Edit: I corrected instruction 5, re-wrote 10, and added a link to the Syslinux Project site and the MAN page for the Linux 'mount' command. |
