10.04 will not install, live cd wants me to log in

[BrandonBan6]

I think this is issue is different from the many posts about the blank screen at start up.

I go to install ubuntu 10.04, downloaded the .iso, burned it... popped it in.. and boot from it. It shows me a purple screen with a keyboard = person at the bottom (I can hit any key here and bring up the traditional install ubuntu or try ubuntu without changing anything menu, but neither of these options change the end result). The the new logo splash screen comes on and then it takes me to a login screen (remember this is the live cd, so I don't have an account to login with).

I have burned several discs on different burners, and re-downloaded the .iso a few times always the same results. I have also followed both solutions here:http://www.ubuntugeek.com/how-to-fix...t-startup.html , but again get the same results.

Hi BrandonBan6.

I'm almost positive, that your disc is bad.

I made 4 coasters, when the release was announced.

Turned out, that braserio, was throwing errors, and the discs were bad in 9.10.

All of the discs would start to load, then the system would boot into my previous ubuntu install.

Sadly, I resorted to burning the same ISO on a windows machine, and it went well.(at 4x speed, as always).

Try logging on, and see if your old install pops up.

I burned my CD in K3B at 8x speed. But when I restarted my computer and went through the installation process, the installer crapped out at 45%. I put the disc in my other optical drive, and the installation went smoothly.

Previously one day, all of my optical drives started producing nothing but coasters, or discs that would partially install Ubuntu, no matter what media or what burn speed.

I lowered my RAM speed in the BIOS, and the problem went away.

So you might want to try another CD drive, or try lowering your RAM settings.

I'm having the same problem booting 10.04 from both CD and USB pen. Checked the file md5sums and everything is OK. Tried logging in using ubuntu and no password, the desktop briefly flashed on the screen then returned to the login prompt. Using a blank user name and password resulted in an authentication error. My old 9.10 Live CD works great without requiring a login. Any ideas would be appreciated. Thanks a million in advance!

Hi Canuknucklehead.

Have you tried entering your password?

I'm just curious if the 9.10 disc burner is the problem.

you guys rock! ... burned it with K3B and it installed just fine!

G'day hansdown,

Thanks for the quick reply! Unfortunately no joy - the ubuntu / no password was the only combination that didn't result in an authentication error.

It appears to be a related to my VIA Unichrome video chipset. I initially discounted that because the login prompt was displayed exactly as on my current 9.10 install.

However, adding xforcevesa to the command line both eliminated the login prompt and displayed the Live CD desktop in glorious 800x600.

Thanks a million for everyone's input!
