I'm encountering boot failure while trying to install a Linux distro from a CD. I'm using an older PC; here are its specs:

HP Pavilion 2.66GHz, 512MB RAM with a BIOS revision of 6/30/2003

I reclaimed an older drive (Seagate ST340810A) that seems to be working, as it's recognized in the BIOS (auto-detected).

I downloaded a mini.iso of Ubuntu 10.10 that I want to install, and burned the image to a CD for install.

My boot sequence is: First Boot Device [CDROM]. I disabled devices 2-4 so I can just force it to read first from the CD-ROM.

This old PC also has a separate CD writer which is a Sec.Slave. The Sec.Master is the Toshiba DVD/ROM DSM-171 drive where I placed the burned Linux CD.

With these settings I cannot get it to boot. I get the message


when I try

Welcome to Super User, @jdamae! Your question is fine here, but just so you know, the people who run SU have a site all about Ubuntu questions as well; it's at – Pops Feb 16 '11 at 0:07
ok, thanks for the tip. i'll post it there too. – jdamae Feb 16 '11 at 0:20

Have you verified the iso you have downloaded?

Has your burning program verified the burnt image?

Does the cd work on another computer?

the image is good. file size matches the download. I just checked it. I can see the config files while opening on my macbook. so, it looks good to me. i don't have another pc to boot it on, except for macbook. – jdamae Feb 16 '11 at 0:16
I'd try and find a friend willing to let you test the disk on their PC. – PriceChild Feb 16 '11 at 9:11

I have seen some older machines with IDE-based DVD units fail to boot/recognise Linux CDs. The fix was to replace the DVD unit with a CD-ROM/CD-RW drive for the install.

Can you remove the DVD drive and make the CD-ROM the secondary master?

i unplugged the DVD drive, made the CD-ROM the secondary luck. still same message. – jdamae Feb 16 '11 at 1:39

Did you download the 64-bit version instead of the 32-bit version? You need to make sure that you download the correct version for your processor, and I'm guessing that it's a 32-bit processor.

You'll need to burn the image as an ISO image and not as a data image. Data CDs are not bootable. Use something like InfraRecorder for Windows (it is easy to use and has an option for burning ISO images).

The bit version would not have an impact on the boot until it tries to install. Or I'm a just guessing here? – TFM Jun 21 '11 at 6:39
@TFM If he has a 32-bit processer, the disk will try to load the included 64-bit kernel on a 32-bit processer, which will NOT work. – tjameson Jun 21 '11 at 7:05
I understand that, but would loading the wrong kernel generate a "DISK BOOT FAILURE" message? – TFM Jun 21 '11 at 7:29
