In May 2009 I asked for and received an airmailed copy of ubuntu version  8.10 which I installed on my desktop AMD  Athlon XP, 2000 MHz (15x133)2400+, having 1.5GHz RAM.  It was smooth sailing for  surfing the net, listening to music and viewing youtube.

A couple of days later,  a pop-up Update Manager came on and told me that updates were available for my version. I clicked update and was told to type my password. It was a longish download due to my slow internet server. Upon downloading and subsequent installation, my version of ubuntu was upgraded to 'jaunty 9.04' (or similar - forget the version).

Ubuntu Jaunty  was fine except that booting up was always exasperating for me as it took more than 3 restarts, sometimes more, before the pc could be booted up.  OK, I'm not complaining 'cause this is a free os and I should be grateful to you guys at ubuntu for doing such great jobs providing free os software to the world.  I salute you.

Last Sunday, as usual I required a few restarts to boot up the pc.  While listening to a song on youtube, I swiched to another window to surf. The music stopped playing and the pc hanged. I waited for about 15 minutes to see if the pc could return to life. But after being certain that nothing would happen , I restarted the pc. It could not be booted up.

I attempted to boot up the pc for the last two days and it seemed that I needed help. The screen showed the following when I start the machine -

"Boot from (hd0,0) ext 3

Please help, thanks.
