I am running v9.04 (netbook remix) on an Advent 4211 (rebadged MSI Wind). I am trying to install v10.4. I have downloaded ubuntu-10.04.2-desktop-i386.iso. Then I hit the problems:

* When I right-click the ISO file, "Write to Disk" is not an option in the menu (as per instructions on http://www.ubuntu.com/download/ubuntu/download).

* When I try the USB option, I find that there is no Startup Disk Creator in the Administration menu.

* I downloaded unetbootin; the file arrived as unetbootin-linux-549 -- Ubuntu seems to think that it is a Windows file as it tries (unsuccessfully) to open it with WINE. I tried forcing it to open with Archive manager, but that won't do it either.

Grateful for any help, please.

Thanks in advance...
