Jaunty won't boot, i will die!!!!

[Will4]

Hey any one,

i just upgrade from 8.04 to 9.04 and everything went well until i had the PC turned off. I mean, now when i turn it on it does not go further than boot splash. don't even let me see the "nice" log in screen. I have all my data there, not saved. Can any one please, tell me how to downgrade to my loyal 8.04 please? I don't want Jaunty any more. Just go back, please. May be once all bugs get SOLVED.
I die first if i lose my data!!

Please, help a so desperate soul. Any help will be very appreciated.

"EYES" XXXXXXX

PLEASE, BE WELCOME TO POST HERE IS YOU HAVE THE SOLUTION. DON'T GET ME WRONG I AM JUST DESPERATE. THANK YOU SO MUCH.

You shouldn't jump from 8.04 to 9.04, bypassing 8.10 in the process. And as far as I know, I don't think you can go back to hardy again once you have upgraded your machine to Jaunty. One thing you could do is to boot your machine with Ubuntu LiveCD. Then mount the partition(s) where you want to save your personal files and copy them to a second CD/DVD drive or an external drive. Once you've done that, you can reinstall either hardy or jaunty again.

Thanks Taurus,

But... will i be able to save the data in my home directory?? Like Documentation i had there!!!???

You should be able to. From the sounds of it, the Jaunty install completed, but it just won't boot.

Use the LiveCD to boot into a desktop environment, mount your hard drives (it should do that automatically) and copy everything onto a USB key or external hard drive.

[Will4]

and what Ubuntu LiveCD??? 8.04 or 8.10 will work???

i don't have 9.04 yet...

[Kareeser]

Any Live CD will work, it is OS-independent.

We can try fixing Jaunty though... what is the error message that pops up when you try to boot up?

[nawitus]

In the Kernel selection menu ( the grub menu ), remove the splash word from boot options by pressing 'e'. That way you can see text print out and hopefully the error. Remove the word 'quiet' too.

Thank you Kareeser,

Actually i will be glad to get a message popped up. It wont go further than boot screen.

the black screen with the Ubuntu and the line down loading the OS
even before it pops the log in screen

it stops there and nothing happens then. Stays so like for ever.

Thank you for helping, Any idea???

Follow nawitus' suggestions. Press "esc" on the GRUB countdown when your computer starts booting and edit the boot line like he suggests.

OK Thanks then

your help is very much appreciated
