i cant get past login screen
 

i am running kubuntu on my netbook (my other laptop) i only have usb drives no disk drives . i did a large update of ubuntu and it went wrong so now when i log in it doesnt accept my password but to get to the login page i have to go to the grub menu and go on latest version n select it from there what can i do to either reinstall ubuntu or open a working account or sumthing like that im not bad on a computer i just dont really know sudo and those things but i can type them into the command promt n know how to follow them

Did you try getting to the virtual terminal? On the login screen, press CTRL+ALT+Fn (could be F1 or F2). You will get a text login. Try your password there. It is possible something went GUI. If you are able to get in through command line, you will atleast have more options in your hand to think about ...

Nice step to make, anyway you can reset you password from your bootloader ...

take a look at this article :

Note : do not use " passwd root " since you do not want to change your root password, instead issue " passwd yourusername ".

I hope that helped.

is there anyway it can be reinstall ubuntu by the command

Well, the idea is not to have to reinstall the OS if it can be solved by simpler ways. Of course, you could install ubuntu using any of the available media or in one of the other ways.

No, but you can refer to nonamedotc post.

what does that mean

It means to go to the link above the J.A.X posted where the members username is nonamedot.

IT MEANS (SIMPLY) THAT THERE IS NO COMMAND TO REINSTALL, TO REINSTALL WITHOUT CD or DVD MEDIA, YOU HAVE TO FOLLOW nonamedot LINK.

i have added ubuntu onto a usb using what ubuntu provided on the webpage what would i do to boot it to my netbook

Just plugin your usb and reboot.

if that did't work (the usb stick did not boot), try to enter your mother board boot list and boot the usb stick.

that depends on your mother board, I hit F2 to get the boot menu.

thankyou its took me months i jsut left it because i gave up finally got it working sorry but how do i mark this as closed or do i just leave it knew to this forum

you are welcome my friend :)

Search for Thread Tools (ctr+f) -> Mark this thread as solved

Kind Regards.

jordanjw, I'm glad the problem is solved, but please use punctuation in your posts. It's very difficult to read text that's essentially one long sentence.
