Kindly help how to write ISO image of Ubuntu 10.10, and what is the error

I downloaded Ubuntu 10.10 ISO, and even did check the ISO image, with MD5.
59d15a16ce90c8ee97fa7c211b7673a8 *ubuntu-10.10-desktop-i386.iso,

 I did get the terminal result.

desktop:~/Downloads$ md5sum ubuntu-10.10-desktop-i386.iso
59d15a16ce90c8ee97fa7c211b7673a8 ubuntu-10.10-desktop-i386.iso
rohit@rohit-desktop:~/Downloads$

Which shows my ISO image is fine. I tried to burn the ISO image to CD using Brasero. But at the end the result showed some Error log, which I pasted below.

When I rebooted my CD, it showed error, that it can run or something, which I couldn't note down.

Later I tried Unetbootin to make a bootable USB. When I again rebooted using USB, it showed this
"SYSLINUX 3.63 Debian-2008-07-15 EBIOS COPYRIGHT(C) 1994-2008 H. PETER ANVIN
BOOT:

And it the system hug their itself, even if I tried Enter key or any, nothing was working..

The Brasero CD writing software showed the below error log, from which even the CD is not working. Now please help me what to do with this ISO when MD5 Checksum resulted that ISO is fine. Even Unetbootin did fine job making my USB copy the installation files, and probably bootable USB.

Now please help me what to do..
