Hi Gerd,

I'm curious about why you added the --reset-mbr option to the livecd-iso-to-disk command under the 'Preparing the USB stick' section of this page,

The earlier section, 'Run livecd-iso-to-disk script,, covers the destructive installation method, if needed.

I think that the page is long and needs to better structure the installation options to avoid confusion and get users more easily to the information they need. --Fgrose 19:08, 30 May 2010 (UTC)


I am not sure, but I think the --reset-mbr option is needed that it works.

I needed an USB stick to install Fedora 13 on a MiniPC. I followed the instructions in the How_to_create_and_use_Live_USB web page. After finishing that it seems that the USB stick is missing the master boot record. So I looked to the Internet again and found the web page: I saw the same commands there, but with a little difference. There is the command "livecd-iso-to-disk" used with the option: --reset-mbr So I repeated the command livecd-iso-to-disk with the --reset-mbr option and it works.

I needed to repeat creating the USB stick again and needed to repeat the installation to be sure that I have not made other mistakes.

It seems that your device was missing a working master boot record. Try deleting your LiveOS directory and re-running the livecd-iso-to-disk script, and see if the installation succeeds.

I've actually never needed to use the --reset-mbr option in my many tests.

Since the default script is advertised as non-destructive, we should only instruct users to use the --reset-mbr option if it's needed for some reason, such as was the case for you. --Fgrose 15:10, 31 May 2010 (UTC)

Hi "Fgrose",

I think an USB stick will not have a master boot record by default or will lose it when a partition will be formated with "mkfs.ext3" or "mkdosfs". So I think a notice to write them would be nice. A seperate page for "How to make a USB device installer from the DVD" would also be nice.
