Thanks jaclaz for your recommendation for using the partnew command, however that ended up messing my partition table up and the flash drive was no longer recongnized . That pointed me to the --in-situ command which I have now put in place of partnew and it works just as great, I got Bartpe and Vistape booting just fine!

GOOD.

I re-read ilko's post about rebuilding the ubcd.iso with the grub4dos components, replaced menus and removed isolinux & syslinux and what not and fixed my menu.lst exactly to ilko's post.

.....

I can't figure it out as I deleted the isolinux folder, is there anything I need to change in the boot folder on the root of the iso?

......

No you did not.

Did you edit the existing .iso with some tool?


Or you actually followed ilko's post and REBUILT the .iso from scratch with this mkisofs command?

mkisofs -R -b grldr -no-emul-boot -boot-load-size 4 -allow-lowercase -o ubcd411.iso d:\ubcd411

What the heck is the (hd0,4) in your screenshot?

Ok, your correct I did not make the iso with the mkisofs command, rather I used magiciso to edit the original, I will tried the command supplied and couldn't get it to work, will monkey with it later.

The (hd0,4) I assume is grub showing that it found & set root to the partition where UBCD is on.

I am lost.

Can you re-cap in a single post what you are trying to do, the contents of your current menu.lst, a brief list of what you have in what (I mean stick, iso image, whatever ) and the contents of the menus you are calling through configfile?

If you still have this:

title		Ultimate Boot CD

root		(hd0,4)

configfile	 /menus/main.cfg

grldr is not "finding and setting root" anything, it simply does what you told it to do, i.e. to ROOT to hd 0.4

Alright. well here it is... I am creating a multiboot USB flashdrive with room for my data on it too. I have it partitioned into a large primary for data, a small one for grub4dos, and a logical broken into 4 smaller partitions 1 each for UBCD Bartpe Vistape and Backtrack 3. Here is my most recent menu.lst:

color black/cyan yellow/cyan



title		Ultimate Boot CD

find		--set-root  /ubcd411.iso

map		/ubcd411.iso (hd32)

map		--hook

root		(hd32)

chainloader	(hd32)



title		BartPE

root		(hd0,6)

map		--in-situ (hd0,6)+1 (hd0)

map		--hook

map		--harddrives=1

chainloader	(hd0,6)/NTLDR



title		VistaPE

root		(hd0,7)

map		--in-situ (hd0,7)+1 (hd0)

map		--hook

map		--harddrives=1

chainloader	(hd0,7)/BOOTMGR



title		Backtrack 3

root		(hd0,5)

kernel		/boot/vmlinuz vga=791 root=/dev/ram0 rw initrd=/boot/initrd.gz init=linuxrc

initrd 		/boot/initrd.gz

Everything is booting fine except for UBCD. I tried modifying the iso with ilko's directions using magiciso in windows, when that was done it produced the error screen above ^^ by booting from iso. So now I am trying to use the mkisofs command but I am getting stuck on an error saying "Uh Oh, I cant find the boot image 'grldr'!" I have searched and apparently it is just a directory problem but I have put grldr in the same folder as the ubcd411.iso and still no avail

mkisofs -R -b ./grldr -no-emul-boot -boot-load-size 4 -allow-lowercase -o ./ubcdfinal.iso ./ubcd411.iso

I am using the original ubcd411.iso for the mkisofs command, this is correct right? I shouldn't be using the one I modified?

The configfiles, how I understand it now, will be called from within the iso after grub mounts the modified UBCD iso. So the only configfiles used are as ilko posted.

Extract ubcd411.iso to d:\ubcd411 as in the example.
Replace MENUS folder, put grldr, grub.exe, memdisk and the downloaded menu.lst in d:\ubcd411, delete syslinux, isolinux folders and boot.catalog, and rebuild the ISO:

mkisofs -R -b grldr -no-emul-boot -boot-load-size 4 -allow-lowercase -o ubcd411_new.iso d:\ubcd411

mkisofs.exe is in d:\

Do not attempt other steps or change anything. Make sure you understand what is what, then amend per your needs.
