Hey guys!

I have a little question. I need to install Ubuntu on a pc which does not have a CD-ROM device. So, I need to make Ubuntu to be able to be installed from this USB Flash disk. I've done some little search and most of the other posts were about to install Ubuntu on the USB Flash, but I want just to burn the .iso there in order to be just like the CD. What have I to do?

Thanks,
unseend

Hi,

If you have another computer that has a cdrom drive (or if you already have 8.10 installed) follow these instructions:

http://www.pendrivelinux.com/2008/11/01/ubuntu-810-install-using-the-built-in-usb-installer/

You don't have to use the persistence feature if your not going to be using the USB device as a portable install (select discarded on shutdown).

If you are running Intrepid there is a builtin usb boot disk creator. Go to System-->Administration-->Create a USB Boot Disk.

You don't need to burn a CDrom you can use an iso of the distribution you want to install.

Unetbootin will install the iso to flash drive, you can then use the flash drive to install Ubuntu to a computer without CD.
If you install usb-creator it will do the same as Unetbootin.

plug your flash disk on your PC
cat /etc/mtab to see which device your USB flash disk is
unmount your flash disk, but let it plugged
enter this command : dd if=<your_iso> of=<flash disk device> bs=1024
now you can boot on your flash disk

I second this. Here's a guide for Unetbootin:

Pretty slick, IMO. :)
