No Booting form DVD-Drive

The following form of the OPs previous posts implies that a DVD drive can be
read by the system.
"
The older computers are not that old: about 3 to 4 years, with CPUs faster
than 3 GHz. But all of them failed to boot from an Install-DVD-ROM.
But you could install Vista as a second operation system.
"
What I would like to know is what messages if any the OP gets on the system
display when an attempt to boot from an installation DVD is attempted when
the BIOS settings are set to boot from the DVD optical drive first.

Hi, Curious.

Yes, I meant to ask about error messages, too, but forgot.

> But you could install Vista as a second operation system.

I kind of skimmed over this since the Vista files could be read from another
source (unlikely, but possible - USB, another HDD volume...). His mention
of multiple "older" computers also makes my idea unlikely - though still
possible. Clutching at straws, I suppose.

Hello again!

First I thank you all for your help!

I must admit that the question has been held to common and was simplified
too much.
I just diskjockeyed a bit at home - first time, it seems, with a VISTA-DVD,
and the result: it boots fine, although my computer is pretty akin to those
at work and even a year older.

And then I remembered why and when I was confused about:

It was all about a Windows 7 DVD! I made that DVD at work (for I have no
writer at home), tried the DVD in that same Computer, and it functioned.
Then at home, I could not boot from that DVD: There was just the message:

"CDBOOT: Cannot boot from CD Code 5".

And with this Windows 7 DVD I made a test at work a bit later: only the
Computers from last summer (on one of them I made the DVD) could boot from
that DVD,
and the Computers bought in 2006 did not - they generated just the same
message "CDBOOT: ..." (all motherboards have an AMI-BIOS).
All the Computer from 2008 have the same writer ..., perhaps the DVDs do not
run in other DVD-Drives properly ... but that is just guessing ...

Excuse my simplifying - I really thought, that DVDs did generally not boot
on those machines. So my thinking does seem to be a bit weak.


Greetings Manfred

A bit of an understatement.

Often CDs and DVDs made on one system will not work on another system. This
is especially true when using +or-RW disks or if they are written at their
maximum speed or when the manufacturer of the optical drive used on the
systems are different.

Ah! Now we are getting somewhere.

The Windows 7 .iso file you download has to be burned to a DVD by using a
program that unpacks and burns at the same time. It appears that not all of
them do the job with the Windows 7 .iso file.

One that does is ImgBurn (FREE)

After the burn is completed it checks to be certain that the information on
the disk matches that contained within the downloaded file.

This disk WILL be bootable - assuming that you have an original Microsoft
download and not one from a warez site.
