Correction:
I meant go over and access (and transfer control) to the C: drive (near the
end of my comments below - and is corrected below).

OK, thanks for this info, Pegasus. I've still got a bit to learn aboutthe

The reason my Dell computer did NOT boot up on the WinXP boot disk is
apparently due to the fact that Dell installs two special partitions to
HD (one for its own utilities, and one for its own image recovery (calledwhere
DSR - Dell System Restore).
So I copied the exisitng and good boot.ini file on the C: drive to the
floppy disk, and that worked. The difference between the more generic
code given below, and mine, is in this critical line:
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Home
Edition" /noexecute=optin /fastdetect
So it needed to be told to go to the second partition (which is indeed
the WinXP system is located my Dell computer).C:,
But I'm still trying to figure out a case where this would be of any use.
Because if the system on C: is so screwed up so that it won't boot up on
how is booting to the floppy to then, in turn, go over and transfer to theC:
drive (as it seems to do here) of any use? I'm still not understandingin
something. (This seems different than is the case for anything I know
Win98SE and DOS environments).manage

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
command.comto
boot up with no operating system on the floppy? I mean, it just stops
there.

*** 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
methodon
it.

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.

- 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
beto 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
isattempting to access the HD as would normally happen except that it
isusing a clean version of those two files ntldr and ntdetect.com. So
boot.inithat basically it?
The floppy is running the bootloader, and it uses the info in
happenedfile 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
lose,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
and it just might start Windows.
Good Luck.
