[saeghe3000]

hi
I have a wonderful problem during installation ubuntu .
I don't want use wubi . when boot with cd and choose "install ubuntu" or "try without install" , I go in a page with brown color that i should give username & password !
why ubuntu want user & pass when i didn't install ubuntu ??!!???

I didn't have this problem with 9.04 or 9.10 . I cleaned previous ubuntu because had problems .

I get .iso file from ubuntu.com yesterday .

That shouldn't happen, and you might want to check the downloaded iso file and the cd for integrity. Try also ubuntu for username and leave the password blank.

i checked this username and pass .
download link : http://releases.ubuntu.com/lucid/ubuntu-10.04-desktop-i386.iso
from this page : http://www.ubuntu.com/desktop/get-ubuntu/download

thank you for your answers

i found new thing !
in the texts of background install appear this message :
sudo : invalid user : ubuntu

i understood that process installation make "ubuntu" user , and in my installation can't make this .

now my question is : could i boot with live ubuntu 9.10 and from that install 10.04 with mi .iso file( or extracted .iso file ) from my USB or hard ?how?

if not : i install 9.10 and upgrade with my .iso file or cdrom .
but how i can this ?

The installation process makes the user that you create, and apparently, the 'ubuntu' username is not a valid one. Simply choose another username.

No.

You can't upgrade using the Desktop cd. If you have to use a cd to upgrade, there is another type called Alternate.

no . i think that you didn't my mean . my mean was a user that make itself . for example did you make your username when boot in Live state? thus what the username that you loged in?
i think is made a user named 'ubuntu' by default in live satate and beginning process installation . during install could make my user .
