Ubuntu 11.04 won't boot after startup screen

Asked by John Shana

I'm new to Ubuntu and after burning the disc and starting off of the CD, I have to hit F6 to get to the Ubuntu Try off the CD/Install page. After I hit "Try" it goes to black then gives this message:

BusyBox v1.17.1 (Ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash)
Enter 'help' for a list of commands.

(initramfs) mount: mounting (dev/loop0 on //filesystem.squashfs failed: Input/output error
Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs

It seems to me that this isn't supposed to happen, it should go to the desktop screen.
My basic system specs are:
504 mb RAM
Intel Core Duo T2400 CPU 1.83 GHz
I'm using a Bytespeed Z62F notebook :(

Did you md5sum check the downloaded iso?
  See https://help.ubuntu.com/community/HowToMD5SUM
Did you burn the cd as slowly as possible?
Did you select the media check before trying to install to check the cd

Did you ever do a "memory check" (another menu choice) on your PC.
Doing the above can save you a lot of time struggling with a bad install media.

Hi, I have the same problem with my old HP. I read a lot in the web and googling much to find a solution. After two week of searching, I found, in a Ubuntu Italian post, a probably replay. The problem seems to happen with old cd reader (how old i don't know); change it with once new and the problem stop. I tested it last week and I was able to install Ubuntu. This problem doesn't effect if you use the DVD ISO. This is what i found, i hope this post can help us with another way. Thanks many.

Can you help with this problem?
