Hello, i hope you can help me, i have a problem making a multiboot cd with Grub4Dos.

I read than Grub4Dos can read directly the SETUPLDR.BIN, and i do it in this way:

title Windows Xp
chainloader /I386/SETUPLDR.BIN

and show me this:

Will boot NTLDR from drive =0xe0, partition=0xff(hidden sectors=0x0)

and then reboot.

i doing form this way too:

title Windows Xp
find /I386/SETUPLDR.BIN
map /I386/SETUPLDR.BIN (0xff) || map --mem /I386/SETUPLDR.BIN (0xff)
map --hook
chainloader (0xff)

and show me this message:

Invalid or unsupported executable format

I tried a lot of ways but nothing works, give me some clue what i missing.

Try EasyBoot and their forums http://www.ezbsystems.com/enindex.html

See my signature for Win7/Vista/other WinPE multiboot dvd. Doesn't fork for xp.

EasyBoot is the thing for what you need. You can find tutorials on their forum.

Thanks a lot, but i really really wanna learn to do it with grub4dos.

title Windows Xp
chainloader /I386/SETUPLDR.BIN

That's correct as for grub4dos.

May be setupldr.bin dosn't find ntdetect.com.

File system, file case and location is importand.

How do you create the whole CD/DVD? Write some details.

The mapping is wrong.

You are mapping an executable to a virtual CD device.

You can map a .iso file to a CD device , but not a loader to it!

WHERE did you find such an example?

Check the grub4dos forum :

An XP install or PE 1.x won't work anyway unless it has special provisions (RAMDISK build).

I reckon it should be (rd) instead of (0xff):
