so hello to forum..i am new to the world of usb multiboot and i should say i was shocked about all the difficulties...i am not particularly hi tech savy but i thought, seen how much spead this pendrives are, it would have been more easier to create such useful tools...

so i used the good program WinSetUpFromUsb found here:
http://www.msfn.org/board/How-to-install-f...SB-t120444.html

and built a multiboot win winxp install bartpe and Gparted...Gparted dooesnt work well but that's another story maybe for a new topic...

so i wanted to add ubuntu and installing from the program just didnt work...i changed isolinux into syslinux and isolinux.cfg into syslinux.cfg (found this info somewhere) but didnt work..off course i also edited menu.lst and changed kernel path...
was not working...

so in the end i started again and first of all i built an ubuntu 8.04 Usb bootable following these instructions:

http://www.pendrivelinux.com/2008/04/09/us...ndows/#more-370

then after i used WinSetUpFromUsb to add bartpe xp install and Gparted....

then after many tries i edited menu.lst like this...

title Ubuntu
root (hd0,0)
kernel /casper/vmlinuz root=/dev/rd/0 pmedia=usbflash boot=casper
DEFAULT vesamenu.c32
PROMPT 0
append file=/cdrom/preseed/ubuntu.seed
initrd /casper/initrd.gz
quiet splash

i am not really aware of what i am doing cause i am not very techy in linux and grub...anyway now it works...
the qemu (usb virtual pc) doesnt work with it , but trying on a real pc was ok...the strange thing was during boot of ubuntu i didnt see any graphics (the ubuntu splash) but verbose comments...

this install menu in try only way..i still have to edit the menu to add "install permanently" and failsafe...

This is not a proper grub4dos syntax. Please copy- paste here or attach the original isolinux.cfg file and we will try to adapt it for grub4dos.

[loopux]

yes i was aware it was not correct...
original isolinux.cfg

DEFAULT /casper/vmlinuz
GFXBOOT bootlogo
APPEND file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.gz quiet splash --

Try this:

title Ubuntu live
root (hd0,0)
kernel /casper/vmlinuz file=/preseed/ubuntu.seed boot=casper quiet splash --
initrd /casper/initrd.gz

[loopux]

ok thanks and for INSTALL ubuntu i should do like this?

title INSTALL ubuntu 
root (hd0,0)
kernel /casper/vmlinuz file=/preseed/ubuntu.seed boot=casper only-ubiquity quiet splash --
initrd=/casper/initrd.gz

or where i put the only-ubiquity?

Just fix initrd=/casper/initrd.gz, t must be:

initrd /casper/initrd.gz

The part after kernel and initrd is the path to vmlinuz and initrd.gz, according to GRUB(grub4dos) syntax, thus no "=" is allowed.
"file=/preseed/ubuntu.seed" is part of the kernel parameters passed, so we leave the syntax as it is, as Ubuntu expects is.

Lets make another example:

LABEL check
menu label ^Check CD for defects
kernel /casper/vmlinuz
append boot=casper integrity-check initrd=/casper/initrd.gz quiet splash --

label-->title
menu label is the writing showing up if we select that item, so we may include part of it in our title.

initrd=/casper/initrd.gz -->initrd /casper/initrd.gz
rest goes as a kernel parameters, removing initrd part:
kernel /casper/vmlinuz boot=casper integrity-check quiet splash --

As a result we have:

menu Check CD for defects
kernel /casper/vmlinuz boot=casper integrity-check quiet splash --
initrd /casper/initrd.gz

If booting it from other partition, root (hdX,Y) should be added, or find --set-root /casper/initrd.gz.
