Thank you all for taking the time to read my question, although after all
the time I've spent in this and other NG's I feel I should know the
answer.
I understand *some* of the basis differences between a disk image, and a
disk clone. Apparantly a clone may be bootable, an ready to run provided
in
it installed in the proper BIOs channel along with it's coresponding
settings.
When people speak about disk images they usually mean an
image file that can be stored on a disk or on a CD/DVD.
My understanding of any ISO image,it is not bootable and it is also a
bit-for-bit reproduction,--albeith in only ONE file?? Apparantly raw ISO
image is *not* bootiful. I don't understand this is that I thought an
image
is a bit-by-bit exact copoy of the original.
Image files are not normally ISO images. They are written in a proprietary
format known to the supplier (e.g. Acronis, Ghost).
I realize we don't usually use AUTOEXEC.BAT and more, or even ConFig.sys,
but there still must be bootable files on an ISO image, that left by
themselves just can boot.
Here are the prerequisites for a WinXP boot:
- A Windows Master Boot Record (MBR)
- ntldr
- ntdetect.com
- boot.ini
All of these are stored in an image file and are put back into
place on a restore.
I know I'm missing something in the boot or file
structure anywhere, and would be so appreciative if one could explain it
to
me, or know of a good site that, in this case, assumes I know
nothing.(That's getting closer all the time ;-(
Why for example can't i make a duplicate XP install disk as a back-up,
using
the native "copy" command, and get it to boot??
If you mean "WinXP CD" when you write "duplicate XP install disk"
then the answer is: You can make a copy. Simply use the "copy"
function of your CD burner.
AArrrrrgggggghhhhh! My
quess this all has to do with different file structures between medium.
Some kind of boot files do not allowed themselves to be copied in this
matter, and I want to know why.
If I take a simple DOS 6.22 disc, do a copy *.* to a destination drive,
(CD)
it works flawlessly. Xp sure doesn't/won't do this As i've said, I'm
open
to all ideas, lectures, or re-directs to other web-sites.
You appear to mix up "installation disk" and "operating disk".
I' asking all this now becuse I've never been with the abiilty to back up,
and had a CD-rom burner before. It's high time **I**finally started
usuing
backups. Yes Rock and others...you finally got through to me)!
Buy a copy of an imaging program (e.g. Ghost, Acronis), then do this:
1. Create an image file.
2. Store it on a removeable disk.
3. Do a full restoration so that you know that it really works.
Thank you for all you time and effort this rather lenght post, (nobody)
has
every accussed my of not enough detail <VBG>
