Multi-boot step UBCD problems!

Featured Replies

I have come to this part

"Now open up ISOBuster and Extract the bootsector of the UBCD.ISO and save it as UBCD.DAT"

I dont now what files in the iso to extract and where should i put the files im going to extract?

Problem 2

I have downloaded the UBCD.zip and opened it with the hex editor but i cant find where the line /CDSH is that im going to replace.

Question

Can i use my Windows xp sp2 disc instead?


You need to extract that zip file first.

Then save the bootsector from the ISO, then edit the bootsector using the hex editor.

i have extracted the zip file and opened it with hex editor but i cant find the line /CDSH.

I have opened the iso in isobuster but what files are im going to extract please say with filenames?

Some screenshots would be nice too

Your still not extracting the BOOTSECTOR...

The bootsector is NOT a file in the cd fielsystem, rather info stored at the beginning of the CD, that allows it to be booted from.

Try UltraISO and open up the ISO, it should say "Bootable" or something similiar, that means you can save the bootsector. So, from here click "bootable -> save bootfile" give it a name!

From there, open the bootsector you saved in a hex editor, then make the changes to it as ncessary.

Here's a screenshot of an ISO i opened up that contains a bootsector.

YOU EDIT THAT BOOTSECTOR THAT YOU SAVED IN THE HEX EDITOR. NOT THE ZIP FILE.

I found that just changing \boot to \UBCD did the trick. I am not entirely sure where all this \cdsh came from the in the multi-guide came from, but the \boot thing worked for me

So the instructions http://flyakite.msfnhosting.com/ for adding the UBCD are confusing and wrong, is all we need to do is change that extracted zip file UBCD.dat from boot to UBCD with hex editor and add it to the AIO-DVD folder and our boot menue,

is it not necessary to extract the boot sector from the iso image of our UBCD, and if so how do we do it with ISOBuster?
