installation problem

[Istvan D]

Hi,

I have a problem upgrading my Ubuntu.
It's an Intel 32bit based laptop, dual boot (with Win7), running Ubuntu since Edgy, right now Maverick is still installed and up. I tried to install 11.04 from a CD, iso MD5 is okay, CD is okay (both burning sw and checking tool on CD say it is). CD works in other machines.
When I boot from CD, it goes until it has to access some parts of the CD (I can get the menu for direct install/memtest/...), but then it gets into some kind of loop, the lines go pretty fast, I can't really read it, but the beginning of the lines is the same, see on the pictures:

Only hard reset helps.:(
Do you have any ideas what might cause this?:confused:
Thx

Not sure if this will help or not, but have you tried failsafe mode, or other boot options?

Also, if you're not, you should select "Try Ubuntu" before installing it.

Just a thought here, but maybe using a usb stick would help. It only has to be a 1GB stick even though the site says 2GB.

Okay, I was able to boot into live CD and install with the "no acpi" option, but after the installation, I cannot boot into Ubuntu (I can boot into my Win though, so GRUB seems to work fine). How can I boot in the installed OS with a "no acpi" option? I did not find any advice in the GRUB2 documentation page on ubuntu.com.
thanks a lot

During boot, did you see a screen with a symbol of a keyboard and a man at the bottom?

I am trying to boot my installed system already (answering your question: yes, when booting the live CD, I see it, and I do check acpi=off there). But now, it looks like this:
- I turn my PC on
- boot logo
- BIOS pwd
- GRUB menu, 5 options: Ubu, Ubu recov mode, memtest, memtest with console, Win
When I press "e", I can edit the options for booting Ubu, but I do not know what to type to turn acpi off. When I boot in recov mode, I get the same screen as posted above.
please help
thank you

PS: BTW, why do I need to turn acpi off now, when _all_ previous releases of Ubu worked fine?
