Dual Boot with Win98 SE

I have a dual boot arrangement with Win 98 SE and Win 2000. Win 98 is
installed to drive C:. Win 2000 is on drive P:.

Windows 98 has died, and will only boot in Safe Mode. If I reinstall Windows
98 (over the present installation), will it affect Windows 2000? I am
worried that something in the boot sector might be overwritten.

Thanks,

More than likely you are correct. Generally Windows 98 is
installed, and then when Windows 2000 is installed subsequently,
it detects the prior 98 and sets up the changed boot menu, files,
etc., so that you have dual boot. Unless you actually install to
two separate physical drives by changing the boot sequence first
in the bios on some machines, but you would know that. Windows 98
would not really be too aware of 2000 since it pre-dated it by a
couple of years. There is a list and explanation of which files
and entries constitute a dual boot at Microsoft's websites and KB,
so you can also look into whether you can do anything with that
too.

Some boot manager software can detect and set up your boot choices
as well, so that or saving and redoing some files and settings
might help.

What you would like to avoid is installing Windows 98 again, and
then trying to install Windows 2000 again to pick up the dual boot
setup, as would have been done originally.

It is hard to say, but if both o/s are start-able from the menu
now, perhaps you can just find out in safe mode what the problem
is with the Windows 98. The fact that Safe Mode works shows
usually that it is the other drivers, etc., that are part of
normal boot mode that could be the problem. Maybe you can fix
this without reinstalling 98? I wouldn't say it is dead as long
as SafeMode is working.

There is the bootlog.txt that maybe might show what is failing,
you record it and then view on next safemode startup. The Help
should be accessible and explain, and the KB articles should also.

Undoubtedly before doing anything, any important data files and
settings for both o/s versions or some kind of off-computer backup
would be wise. You can always reinstall both o/s and all o/s
updates, and all software, and then restore all data files last,
if the worst should happen.

It would be nicer if you can just remove a video driver, or
incorrect device driver or something, and get it normally booting
again, however. Any idea what was last done to make it go wonky?

I am using PowerQuest's Boot Magic as a boot manager. I know which files in
the C: (Win 98) drive belong to Win 2000's boot sequence.

My only concern is whether either Win 98 or Win 2000 has placed something in
the boot sector of the disk that I don't know about.

Not sure how Boot Magic works, but I'm operating under the assumption that
it changed the MBR of the disk you're booting from. Win98 and Win2000 have
it's own boot code in the partition's boot sector.

Ok, just as a guess, I would say if you rely on the PowerQuest
Boot Magic, it would look after things supposedly. If you run the
Windows 2000 Recovery Console from either a bootable CD or from
having it installed (see the Help), then you might be able to use
the boot fix or mbr stuff in there, after reading up about it
either in the Help or at one of Microsoft's websites for Windows
2000 and recovery console topics.

Windows 2000 should pick up info about Windows 98 and itself, and
hopefully fix anything that might be odd-ball. Then maybe Boot
Magic can take over again, but I haven't tried anything with that
other than a limited version which allows me to install Linux
along with the other two, and I have since just gone to Windows
2000 Professional on this machine for now, and done away with the
triple boot setup I had been using. Good luck. For further study
of the setup, you could probably compare two machines, such as
yours and another with pristine installations of your choices of
o/s. You can use file dates, and names, as you say, and probably
stuff like Debug to look at file and sector contents, if you
really want to get into it at a more detailed level. Sometimes I
have just saved all files (*including hidden) and tried to restore
them later, but this doesn't always work out for some reasons.
You sound like you already know quite a bit about it, so hopefully
you will get more information that you might need. Microsoft's
TechNet might be helpful, along with some of their Webcasts as
well. There are also Technical References and Field Notes that
might help, although I haven't personally read them yet. Sorry
about the long post-reply.
