FreePBX Problem

Hello,
I want to install FreePBX Destro on my server but I got this message: ISOLINUX 4.02 2010-07-21 ETCD copyright © 1994-2010 H. Peter Anvin et al EDD: Error 3200 reading sector 277397. No Default or UI Configuration directive found.

So please what I have to do then?
Thanks for helping to solve the problem.

burn thr cd again, this time check the md5sum against the published one.

well, please I cant found where to check md5sum

It is conveniently available in the link just next to the distro download on the download link at the top of this page, to save you too much effort I will post the download link for you here also:-

http://www.schmoozecom.com/distro-download.php

look for the characters (all in a row) that spell out MD5SUM, use the one next to the iso you are using.

Thanks, I found MD5SUM and I have to download MD5SUM or full ISO? because MD5SUM have only 1kb

THE MD5SUM is the checksum generated by running and MD5 check on the ISO. If the checksum you get does not match the MD5SUM then you have a bad download.

and an md5sum of /dev/cdrom (or wherever the cd is mounted on) should give you the same checksum , if not you burned the cdrom badly.

for example:-

cat FreePBX-1.1008.210.62-i386-Full-1348166937.iso.md5sum
6c8125f30a76880e41f4e375df20e36e FreePBX-1.1008.210.62-i386-Full-1348166937.iso

user# md5sum FreePBX-1.1008.210.62-i386-Full-1348166937.iso
6c8125f30a76880e41f4e375df20e36e FreePBX-1.1008.210.62-i386-Full-1348166937.iso

when FreePBX-1.1008.210.62-i386-Full-1348166937.iso burned to cd is mounted on /dev/cdrom:-

user# md5sum /dev/cdrom
6c8125f30a76880e41f4e375df20e36e /dev/cdrom

i LOVE YOU GUYS, its DONE. THANKS VERY MUCH BUT I HAVEN’T FINISH INSTALLING JET. SO IF ANYTHING, I WILL INFORM YOU GUYS.
