Grub4dos can chainload setupldr.bin: no need for a boot sector file.

That's great! As I understand it, I need mkisofs to create the iso like this:

mkisofs -R -b grldr -no-emul-boot -boot-load-size 4 -o grldr.iso iso_root

and I read a lot about different versions of mkisofs, is there any version specifically fitting for XP x64 that you are aware of?

title Windows XP PRO 64 SP2 - multi boot 
map --mem /XP64/I386/SETUPLDR.BIN (rd)

OK, this is loading the unaltered setupldr.bin location; How would grub4dos work together with your layout as described above in Post #2? I assume nothing changes, except for the setupldr.bin being under /I386/ which needs to be hexedited still, correct?

Try at any mkisofs version you can find: mk_XP64.cmd

mkisofs -iso-level 3 -N -D -d -relaxed-filenames -allow-multidot -joliet-long ^
 -r -b grldr -hide boot.catalog -no-emul-boot -boot-load-size 4 ^
 -o XP64.iso -o XP64.iso iso_root

Yes, /XP64/I386/SETUPLDR.BIN is the original file.

Yes, should work

title Loading XP install - plain /I386/SETUPLDR.BIN
chainloader /I386/SETUPLDR.BIN

Yes, should work

title Loading XP install - plain /I386/SETUPLDR.BIN
chainloader /I386/SETUPLDR.BIN

Just to be sure, you mean:

title Loading XP install - plain /XP64/I386/SETUPLDR.BIN
chainloader /XP64/I386/SETUPLDR.BIN

in your layout, correct?

And

.\XP64\WIN51

.\XP64\WIN51AP

.\XP64\WIN51AP.SP2

.\XP64\NTDETECT.COM

.\XP64\TXTSETUP.SIF

should all still stay there?

Just to be sure, you mean:

Setupldr.bin location doesn't matter at grub4dos. Load the appropiate file.

The edited Setupldr.bin was at /XP64/SETUPLDR.BIN.

If you like this one, chainload this one.

If you like to use another one, chainload the another one.

The original one was at /XP64/I386/SETUPLDR.BIN

Use grub4dos to change this file in RAM.

Keep all files as described previously, there is no change.

The original one was at /XP64/I386/SETUPLDR.BIN

Use grub4dos to change this file in RAM.

LOL, hexediting it in memory is a neat and cool option, but somehow I'd rather do the hex-editing beforehand.

Thanks for all the hints. Should all work now.

Is replacing all the amd64 entries as in

really safe?

@cdob

watch out, I have a deja-vu feeling :

Babe: You're talking to me?

Christian Szell: Is it safe?

Babe: Is what safe?

Christian Szell: Is it safe?

Babe: I don't know what you mean. I can't tell you something's safe or not, unless I know specifically what you're talking about.

Christian Szell: Is it safe?

Babe: Tell me what the "it" refers to.

Christian Szell: Is it safe?

Babe: Yes, it's safe, it's very safe, it's so safe you wouldn't believe it.

Christian Szell: Is it safe?

Babe: No. It's not safe, it's... very dangerous, be careful.
