OK, but I'm evidently still missing something here. (I'm trying this
out
now on a good system just to see). (and I'm coming here as a past
Win98SE/DOS user)
Given what is quoted below for a basic formatted disk, how does it manage
to
boot up with no operating system on the floppy? I mean, it just stops
there.
*** Which boot disk are you talking about? The WinXP boot disk

*** The WinXP boot disk will boot the machine into Windows XP,

*** The Win98 boot disk will boot to an "A:\ prompt".
I actually tried it out, and nothing happened except that I was stuck at
the
"a:" prompt, (but this only AFTER I had created a floppy with command.com
on
it.
*** If you download the Win98 boot disk from www.bootdisk.com

Otherwise I got the error Invalid System Disk).
My test prior to that it was just using a basic formatted diskette (with
no
OS on it), and it wouldn't boot, which seems right.
*** I said "Use a disk formatted on a WinXP PC, then copy . . ."
*** If you stop after the formatting step then you obviously won't

- Format a diskette on a WinXP PC.
- Copy these files to it from the i386 folder of your WinXP CD:
ntldr and ntdetect.com
- Use notepad.exe to create a:\boot.ini on it, with these lines:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /fastdetect /NoExecute=OptIn
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP
Professional" /fastdetect /NoExecute=OptIn
multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Microsoft Windows XP
Professional" /fastdetect /NoExecute=OptIn

The benefit of a Win98 boot disk is that it gives you very
basic access to the hard disk where you can perhaps
repair the damaged boot environment.
Both disks are useful to have. A Bart PE boot CD is even
more useful to have but it takes time to make one).

Well, my system boots up fine now, but I was just wondering if this
waymakes a good backup disk to supplement the MSDOS backup one?
So if windows didn't boot up, I presume this method would be the first
to try, and if that fails, maybe you'd need the MSDOS boot disk. Is
that
correct?

No need to change "Professional" to "Home". It's only a label for a
human to read.
OK. It's just a text label then.
I'm curious as to how it works, if you can't even boot up in WinXP
normally. Just looking at the lines below, it seems (to me) to just be
attempting to access the HD as would normally happen except that it is
using a clean version of those two files ntldr and ntdetect.com. So is
that basically it?
The floppy is running the bootloader, and it uses the info in boot.ini
file to find/start Windows.
The 3 choices you'll see are only an attempt to cover all bases of
where your particular Windows installation might be.
It's most likely that only 1 will work, depending on what has happened
to your disk, and whether you've attempted a repair install and
actually ended up with a parallel install.
Make the floppy, and give it a try. You've really got nothing to lose,
and it just might start Windows.
Good Luck.
