Well,after a lot of hard work I managed to have all the iso's on one cd,but almost none is working with the exception of parted magic and ubuntu mini.So here is what i did: -I made a directory called Multiboot,where I put the folowing folders and files: Multiboot/boot /clonezilla /isolinux /mini /ping /pmagic /reactos /ubcd plogic69.img sgd9701.img The /boot folder contains following subfolders: boot/clonezilla /isolinux /mini /ping /reactos And finaly ,the Multiboot/boot/isolinux folder do have inside these files: -chain.c32 -isolinux.bin -isolinux.cfg -memdisk -splash.png -vesamenu.c32 Now,the isolinux.cfg from Multiboot/boot/isolinux is this: DEFAULT /boot/isolinux/vesamenu.c32 PROMPT 0 TIMEOUT 300 TOTALTIMEOUT 450 #### MENU BACKGROUND /boot/isolinux/splash.png MENU TITLE Super-Disc #### #### The 1st byte of the fgnd color is brightness. #### green1 MENU COLOR title 1;36;44 #ff008080 #00000000 std #### green1 MENU COLOR unsel 37;44 #ff008080 #00000000 std #### white MENU COLOR sel 7;37;40 #c0ffffff #ff000000 std #### orange MENU COLOR hotkey 1;37;44 #fffe3e00 #00000000 std #### green2 MENU COLOR hotsel 1;7;37;40 #ff00ff00 #ff000000 all #### LABEL hdd MENU LABEL ^1 Boot from HardDisk localboot 0x80 LABEL ubcd MENU LABEL ^2 UBCD 4.1.1 KERNEL /ubcd/isolinux/menu.c32 APPEND /ubcd/isolinux/isolinux.cfg LABEL pmagic MENU LABEL ^3 Parted Magic 2.1 KERNEL /pmagic/vesamenu.c32 APPEND /pmagic/isolinux.cfg LABEL ping MENU LABEL ^4 PING (Partimage Is Not Ghost) KERNEL /boot/ping/kernel APPEND initrd=/boot/ping/initrd.gz LABEL clonezilla MENU LABEL ^5 Clonezilla KERNEL /boot/clonezilla/vmlinuz1 APPEND initrd=/boot/clonezilla/initrd1.img LABEL plogic69 MENU LABEL ^6 Partition Logic kernel memdisk append initrd=plogic69.img LABEL sgd9701 MENU LABEL ^7 Super Grub Disk kernel memdisk append initrd=sgd9701.img LABEL mini MENU LABEL ^8 Ubuntu Mini KERNEL /boot/mini/linux APPEND initrd=/boot/mini/initrd.gz LABEL reactos MENU LABEL ^9 ReactOS 3 KERNEL /boot/reactos/setupldr APPEND initrd=/boot/reactos/freeldr LABEL memtest86 MENU LABEL ^Memtest86 (RAM Diagnostic) KERNEL /boot/isolinux/memtest86 My question is what have i did wrong,because from all these 9 entries in the isolinux.cfg menu,only 3 are working:1.Boot from HardDisk 3.Parted Magic 2.1 and 8.Ubuntu Mini.Even the Memtest86 isn't working.I'll post here the messages i receive from virtual box(the virtual machine i'm using to test may work): 2.UBCD 4.1.1 - here if i press this option ,i get a second screen with 2 options:boot and main.if i choose main nothing's happening only a refresh of the virtual screen,and if i choose boot ,a message saying "Booting..." appear at the bottom of the virtual screen and freeze there. 4.PING(Partimage is not ghost) - here ,after receiving the messages "Loading.....kernel" , "Loading.....initrd.gz" and "Uncompressing Linux" the screen star to display a lot of task lines like when a linux distro is booting ,and after some time the machine is displaying this:"Kernel panic - not syncing: VFS:Unable to mount root fs on unknown-block(3,2)". 5.Clonezilla - nothing is happening when pressing this option in the menu,only the virtual screen is refreshing.The cursor continue to remain on this line. 6.Partition Logic - choosing this the screen is changing and is displaying these:"Loading memdisk......Could not find ramdisk image: plogic69.img". 7.Super Grub Disk - same as above with only one difference:in-stead of "plogic69.img" the word is "sgd9701.img". 9.ReactOS 3 - the same thing like when i pressed 5.Clonezilla.The screen is refreshing keeping the cursor on this option. And finally the Memtest86,same as ReactOS and Clonezilla. So to conclude what do i have to do to make this multiboot cd to work?I need a little more help from you kof94.Anyother forum member wanting to give a little help offering solutions is very welcomed.Thank you. PS.I thank jetman for his guide http://www.msfn.org/board/Super-Disc-Multi...NUX-t94398.html that was very helpfull for starting my personal project.I used his methode (and his isolinux.cfg menu) in combination with very usefull informations and guiding provided here in this thread by kof94,to whom i thank also.
