can't open, input/output error

I recently mounted ubuntu 9.04 to a cd/r disc, put it in and installed inside windows. Then it told me I needed to restart.

I turned off my computer and tried to boot from the ubuntu option at the beginning next to windows

And it just kept blinking an underscore, for over an hour before I turned off my computer and tried to boot from the CD. When I was at the screen for the disc I had an option to install, so I chose that.

It did some stuff, and then said

"
* Preparing restricted drivers...
* Starting kernal event manager...
* Loading hardware drivers...
scsi_id[3153]: can't open /etc/scsi_id.config: Input/output error

scsi_id[3156]: can't open /etc/scsi_id.config: Input/output error

scsi_id[3157]: can't open /etc/scsi_id.config: Input/output error

Unit: rc-default main process (3289) terminated with status 127.
"

What should I do to fix this?

RE: can't open, input/output error

Read this on another forum (http://ubuntuforums.org/showthread.php?p=4769702), may be worth a try:

Copy the file 'telinit' from /sbin on a live CD to that same folder on your installation.
