Hello Guys

Norton has a free utility called nbrt, an updatable virus scanner that can be converted to an iso

http://security.symantec.com/nbrt/overview.aspx?lcid=1033&origin=default

After installing the iso with Sardu,and booting nbrt in other isos, I get the grub> screen, it doesnt seem to load the iso.

Any tips on getting this to work

My iso_extra.cfg has this

#boot di NBRT
label Boot from NBRT
menu label Boot from NBRT (GRUB)
MENU INDENT 1
kernel /boot/grub.exe
APPEND --config-file=" map /ISO_Extra/NBRT.iso (0xff);map --
hook;chainloader (0xff)
#

I also tried this

#label Boot from NBRT
menu label Boot from ^NBRT
MENU INDENT 1
kernel /boot/grub.exe
APPEND --config-file="map ISO_Extra\NBRT.iso (0xff);map --
#hook;chainloader (0xff)

And it still doesnt work

Hi alochet

This may or may not fit your needs,
here is a script for NBRT I wrote some time ago.

Try this - note that the APPEND line is a single long line


#boot di NBRT

label Boot from NBRT

menu label Boot from NBRT (GRUB)

MENU INDENT 1

kernel /boot/grub.exe

APPEND --config-file="map /ISO_Extra/NBRT.iso (0xff);map --hook;chainloader (0xff)"

The ISO is WinPE 3 based. To make it work, it needs to find the NBRTSTRT.exe file in the root of the drive and also you need to copy these two folders from inside the ISO to your USB drive, so as well as the ISO file on your USb drive you need:

NBRTSTRT.exe
SourcesDRIVERS
SourcesSYMANTEC_NBRT

Hey RoyM, I have no idea what to do with that script, thanks anyways

Steve6375, I tried your configuration, but it still did not fix the issue. I also copied all the files like you said

Here is the content of my iso_extra.cfg, do I have to change anything else in another .cfg file?

If you get to the grub prompt try typing in the commands:

map /ISO_Extra/NBRT.iso (0xff)
map --hook
chainloader (0xff)
boot
describe what happens on each command and see if it boots.

Oh wow I figured out the problem

It gave me this error 60: File for drive emulation must be in one contiguous disk area , in which case memory mapping or defragmenting the file, and then retrying, should be attempted.

So I defragmented the iso file itself with Disk Defrag, Then ran sardu and it worked!

I wish sardu would auto defrag the files like XBoot, this would of saved me a lot time

Thanks for the help Steve

I could have told you that if you had told us what the error message was! RMPrepUSB has WinContig built in. Disk Defrag does not always defrag files.

Why not run NBRT with-in your project?

I'm using the Enterprise version and it works fine.
