How can I update from 9.04 to 9.10? Every time I try it leaves me in a terminal screen and all my programming experience is in DOS and Windows and I have no clue what to do with it.

Since the latter part of October I have been trying to upgrade my ubuntu 9.04 to 9.10. I have a wubi system on two computers both Athlon 32 bit bus one with 900 Mhz and the other 1.2 Ghz. I had some coughing spitting and sputtering at first but it finally settling down and works fine on the 900Mhz machine, but I can't get the other one to upgrade. I have tried to install it from the internet, from the disk I made from the image, from a disk you sent me and even a start from scratch with 9.10disk, and every time I get the same result with a terminal screen in some mode I have never seen, not the command screen. It seems as though monitor is not connected and the screen looks much like the old DOS or an old emac screen in Unix, and it has a limited command list. It calls itself something like mash or something like that.

All of my programming experience is in DOS or Windows except for one Pascal course I took on a Unix system with dumb terminals.

What is the answer?
