Ubuntu

I/O ERROR

Asked by Rob B

I have downloaded the iso file for Ubuntu 8.10 used md5 summer to check the file and burnt to disk at slowest speed. When I try to boot into the OS I get the start page with options and no matter which option I select I get the message I/O ERROR ERROR READING BOOT CD. The box I am using for this is AMD Athlon 2500+, Asus A7V600-X motherboard, 640 MB Ram. The file I downloaded is the i386.iso. What am I doing wrong?

try using a different brand of cd media. dont use cdrw only cd-r. you could also try to replace your data cable for the cdrom, or try a different cdrom. to make sure the disc is okay you can boot the livecd to another computer.

By the way when you do get far enough i recommend setting up a dual-boot system rather than committing to a single OS. Some games and things work slightly with Windows still.

For your current issue hopefully this will help if nhasian's didn't

Also it might be worth trying a completely different tiny distro just to see if you can use it as a LiveCd, ie boot up off the Cd without installing anything to your machine but get to a working desktop. Either of the following would be good to try, or something similar

Please let us know how it's going soon.
Good luck and regards from

nhasian, have done as you suggested and tried the disk on another computer no problems, boots in perfectly. The only difference is that the second computer runs an Intel Pentium 4 whereas the box I want it on is AMD. Any more suggestions?

Tom, thanks I had a look at those pages and will try some of the suggestions. This is a dual boot solution.

Hmmm, the cpu is 1.8Ghz and you've got plenty of Ram so i can't really see what the trouble is. Perhaps there's a problem with the Cd-drive itself? I think trying a faster data-cable inside the case to connect the Cd-drive to the mbord might help. Maybe if you could try using an external Cd-drive or plug a different one in internally for a quick test. The only issue i saw from a very quick google search was that people often replace the cpu fan and heatsink because the fan the machine gets shipped with is a bit noisy and the heatsink isn't copper. Lol, not relevant issues here. Apparently it's a superb mbord for over-clocking and allows a lot of tweaking :) Sounds a lot like my machine :) Mine's currently over-clocked from 1.8GHz to 2.8Ghz and that's not even pushing it's limits :)

Good to hear you're going for a dual-boot. Much more enjoyable and flexible.

Good luck and regards from
Tom :)

Phew, brilliant - nicely fixed

PS both my machines have 1 new(ish) and one old cd-drive. I use the old drive for most stuff (unless it struggles) in order to reduce wear-and-tear on the new one. The old one on the old machine is a real work-horse tho :)
