I/O Error on trying to install from CD

Asked by Simon Orr

Hello,

I've burned the 32 bit 10.04 image countless times to CDs and DVDs alike, and for all of them the installer gives a dialog box titled "I/O Error" with text along the lines of "failed to boot from disc". I've verified the discs. I've gotten the same results on two computers. Now, there are a couple things which make me wonder if the iso which I'm installing from is intact, namely that it burns (not including finishing) in about 15 seconds and it downloads in 45 (whereas the 64 bit download took me about an hour). I've tried downloading it again with the same conditions and results. Please help!

Beating the air in fury,
Simon

Did you MD5 test the ISO?
Did you check the CD for defects?

The main ubuntu site is this: www.ubuntu.com and the download location is this
http://www.ubuntu.com/desktop/get-ubuntu/download

Prerequisites: https://help.ubuntu.com/community/Installation/SystemRequirements
Please also be sure to read the release notes: https://wiki.ubuntu.com/LucidLynx/ReleaseNotes

1) please download the 700 mb file http://www.ubuntu.com/desktop/get-ubuntu/download simply press on download button
To avoid download errors please prefer to download the desired ubuntu iso install cd image using the torrent protocol.
2) check the md5sum of downloaded file to be sure it have no error https://help.ubuntu.com/community/HowToMD5SUM

Only if the md5sum number match with this: http://releases.ubuntu.com/10.04/MD5SUMS go to the next steps otherwise
install a torrent client i suggest you http://deluge-torrent.org/ if you are using Windows and download the iso using a .torrent link from here:
http://releases.ubuntu.com/10.04/ubuntu-10.04-desktop-i386.iso.torrent

3) burn the iso file onto a cd to do it install and use http://infrarecorder.org/?page_id=5
4) insert the self made install cd into your pc cdrom drive and reboot your pc. You must not see Windows starting and you can try Ubuntu from cdrom and then install it

If you have trouble with installation (the system freeze or you can't complete it) be sure to read the above suggestions, then:
1) check cd for defect
2) perform a memory test

Ask new question if you have trouble installing or if you have any doubt.

Hope this helps
