grub4dos with bartpe etc....

the steps are:
A . CREATE BARTPE_INRAM.ISO (NEED RAM DISK OR BSoD when boot up into BARTPE)
    * 1. Download MS Windows Server 2003 Service Pack 1 (RC). It is a SFX CAB archive. You may use WinRAR to open it. Extract the SETUPLDR.BIN and RAMDISK.SY_. Expand ramdisk.sy_ to get RAMDISK.SYS.
    * 2. Build a normal pebuilder.iso with any source you like but
      replace the driver RAMDISK.SYS with the one from W2k3-SP1 (keep however the size sufficiently small since the whole iso will be loaded in RAM)
    * 3. From PEBuilder output directory take bootsect.bin and i386\ntdetect.com
    * 4. Create a WINNT.SIF text file containing the code
      CODE
      [SetupData]
      BootDevice = "ramdisk(0)"
      BootPath = "\i386\System32\"
      OsLoadOptions = "/noguiboot /fastdetect /minint /rdexportascd /rdpath=pebuilder.iso"
    * 5. Create a folder, say C:\rampe, UPPERCASE the 5 files above and use them to create within C:\rampe the following structure
      CODE
      BOOTSECT.BIN
      WINNT.SIF
      PEBUILDER.ISO
      I386\NTDETECT.COM
      I386\SETUPLDR.BIN
    * 6. Create the new pebuilder_inram.iso with mkisofs. Use something like
      CODE
      mkisofs.exe -iso-level 4 -volid "BartPE" -A PEBUILDER/MKISOFS -sysid "Win32" -no-emul-boot -b BOOTSECT.BIN -hide BOOTSECT.BIN -o pebuilder_inram.iso "C:\rampe"

As one can easily see, it is very easy to include a RAM version in a multiboot CD.
Simply use the known method to add multiple OS (hex edit bootsect.bin, setupldr.bin and rename I386)

B. FORMAT external USB drive with HP format tool(NTFS)
C. CREATE BOOTABLE MBR with Grubutil GUI
D. COPY default, grldr, menu.lst FROM grub4dos folder to formated usb drive
E. EDIT menu.lst with proper entries.[/color]
