I understand this post has been a while, but i'm hope someone could contribute to my unsuccessful Multi-Boot with MagicISO in the making. Ok, I found this tutorial here: http://www.magiciso.com/tutorials/miso-cre...multi-os-cd.htm According to this information they only show how to edit Win98, Win2K and WinXP 32bit. I have a few of WinXP 64bit discs that I would like to compress it into one neat DVD instead. WinXP 32bit has a folder called: i386 -However- WinXP 64bit has both i386 and AMD64, the differences not eded there. In 32bit both SETUPLDR.BIN and TXTSETUP.SIF within i386 folder and 64Bit version it has SETUPLDR.BIN in i386 and TXTSETUP.SIF in AMD64 So i guess my question is how to compile a MULTI-BOOT-DVD Windows XP's 64bit with MagicISO Windows XP 32bits *.SIF file is to edit [sourceDisksNames.x86] but in 64Bit it has another section called [sourceDisksNames.amd64] Any feedback will be much appriciated.
