<div dir="ltr"> Thank you for your kind suggestions - but sadly, it did not work... I am trying to dump an ISO that is actually an ISO9660 on a USB pen drive recognized by the BIOS as a USB-HDD. Changing the boot priority did not work for my BIOS, but I'd like it to work on the move. I'll be fair and paint the whole picture: I have an old 65 MB pen drive with a physical lock button (to make it read only). I thought it would be a good idea to make this pen drive an Anti virus on the go - I'll lock it when I use it to scan computers and unlock it when I want to update the definition file. I found the free Linux-based Avira Rescue CD, a 50MB ISO for a CD-ROM. It's updated a few times a day, so I thought it would be nice if I could have it on my pen drive and update it as necessary. I couldn't find any explicit instructions to put it on a USB pen drive, so I tried to do it on my own. I found this post, which relates to a Win32 utility: <a href="http://ubcd4win.com/forum/index.php?showtopic=9888&mode=threaded&pid=55631">http://ubcd4win.com/forum/index.php?showtopic=9888&mode=threaded&pid=55631</a> I tried to adapt it to Linux, but I don't know how. Any of you out there can point me to a HOWTO / guide for this to work? If you know of another AV with a USB image available, I'd be glad to give it a try, but I want it to be free (as in beer ;-) and Linux-based.

However the USB pen drive is a disk for the kernel. So you would have to adjust the boot device. Further more with both my machines which support booting from USB there are 2 possible methods to try booting from USB but only one of them works. I can set the BIOS to boot from USB device then (CD/DVD then) disk - that method works. I can also put the USB device at another position in the boot sequence and select it from the BIOS boot menu but that method doesn't work (but it works for CD/DVD). So maybe your problem is related to the BIOS settings. Can you check with a "normal" Ubuntu boot disk installed to a pen drive? I'm not sure if these links apply - and maybe you know them already: <<a href="http://unetbootin.sourceforge.net/" target="_blank">http://unetbootin.sourceforge.net/</a>> <<a href="https://wiki.ubuntu.com/LiveUsbPendrivePersistent" target="_blank">https://wiki.ubuntu.com/LiveUsbPendrivePersistent</a>> <<a href="https://help.ubuntu.com/community/BootFromUSB" target="_blank">https://help.ubuntu.com/community/BootFromUSB</a>> Nils <div><div></div><div class="h5"> -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </div></div></blockquote></div> </div>
