Dear all,
This is my 2nd tutorial about the same subject, because many readers are emailing me saying that the ISO file changed from Knoppix to Xbuntu and so my First Tutorial is not working with the new ISO image from BitDefender, and they asked me for another tutorial to be up to date, so here we are:
1- You need a Windows based PC to work with this tutorial, and if you are working from Vista or 7 then you need to work with elevated privileges (Run as Administrator).
2- You need a clean empty 1 GB or better USB 2.0 or better.
3- Download the Bitdefender Rescue CD ISO image from the official download link HERE.
It’s a 319 MB, SAVE the ISO image to your desktop.

Posted Image

4- Download the following 11.3 MB essential files from HERE , extract the file onto your desktop, you should see 3 folders (BIT-FILES + USB_FORMAT + GRUB4DOS).

Posted Image

Posted Image

5- Open folder USB_FORMAT and execute usb_disk_storage_format.exe and follow the pictures

Posted Image
Posted Image

6- Open folder GRUB4DOS and execute grubinst_gui.exe and follow the picture below:

Posted Image

7- Now open folder BIT-FILES and copy all of its contents to the USB thumb drive.
8- Copy the bitdefender-rescue-cd.iso image you downloaded, copy to the USB thumb drive, the files now should look like this inside the USB thumb drive, make sure they are:

Posted Image

9- Now the USB thumb drive is ready to be tested, go ahead and boot your pc with the Bitdefender Rescue USB you just made, first thing you should see this screen, press ENTER to continue:

Posted Image

10- In few seconds you will see the following screen asking you to accept the EULA to proceed:

Posted Image

11- After that if the computer is connected to the internet then the updating process will start automatically:

Posted Image

12- When updating is done, the scanning process will start also automatically, you can browse the internet while the scanner is doing its job or explore the many other utilities included in this rescue CD.

Hi Jamal,

Why is the \casper folder in your download needed?

I tried this (just 3 files needed - iso, grldr and menu.lst) and it seemed to work OK ???. Do you need the \casper folder to make changes persistent? I do not know much about linux so I hope someone can enlighten me?

1. Format using RMPrepUSB (FAT32, DOS, HDD)
2. Click on Install Grub4dos
3. Place menu.lst file on stick

menu.lst
title BitDefender Rescue CD 2010

map /bitdefender-rescue-cd.iso (0xff)

map --hook

root (0xff)

kernel /casper/vmlinuz boot=casper persistent iso-scan/filename=/bitdefender-rescue-cd.iso 

initrd /casper/initrd.gz

Nice tutorial Jamal.

I have one suggestion.Why don't you use RMPrepUSB Created by steve6375 in your tutorials?
It is a very good tool and also includes the grub installer.

RMPrepUSB is one of the best tools ever created by the Boot-land.net community.
It would be very nice if you could update your tutorials with RMPrepUSB as the USB Formatting tool.

Thank you steve6375, using your method works but not on all USBs, some will hang up for a long time waiting for the ISO to be extracted, my method is to speed up the booting process 10x times,thank you again.

ISO files are never extracted.They are loaded in ram ,and that only in case if bitdefender-rescue-cd.iso file is fragmented.
Method by steve6375 is slow only in case when bitdefender-rescue-cd.iso is fragmented.

so steve6375's method should be:

1. Format using RMPrepUSB (FAT32, DOS, HDD)
2. Click on Install Grub4dos
3. Place menu.lst file on stick
title BitDefender Rescue CD 2010

map /bitdefender-rescue-cd.iso (0xff)

map --hook

root (0xff)

kernel /casper/vmlinuz boot=casper persistent iso-scan/filename=/bitdefender-rescue-cd.iso 

initrd /casper/initrd.gz
4) copy bitdefender-rescue-cd.iso to usb root.
5) defragment bitdefender-rescue-cd.iso. ( i don't think this is a hard step for a noob)

step 5 is not necessary as I thought that if you copy a file over to a freshly formatted drive it will never be fragmented. It will only be fragmented if you edit, or delete and then copy more files to the drive.

Also, I cannot see why having the casper folder on the USB drive actually does any good?
The grub4dos command map --hook and then root (0xff) actually sets the path to the files within the iso, any reference to /casper files will be directed to the iso file and not the files in the root of the drive - won't it? Or does linux suddenly start reading the real drive and ignore the BIOS remapping that grub4dos does?

Very well said .
After hook command casper folder on real drive will not be read by grub4dos. And that will make the casper folder useless.

The correct entry in jamal's tutorial should be
title BitDefender Rescue CD 2010

kernel /casper/vmlinuz boot=casper persistent iso-scan/filename=/bitdefender-rescue-cd.iso 

initrd /casper/initrd.gz

Method by steve6375 is slow only in case when bitdefender-rescue-cd.iso is fragmented.
5) defragment bitdefender-rescue-cd.iso. ( i don't think this is a hard step for a noob)

1- Thank you shamurshamur for your input, as far as I know ISO images when loaded in RAM they are unpacked = extracted, as you see in picture below from this very same bitdefender:

Posted Image

2- Fragmented ISO images does not cause slow booting at all, they cause the whole booting process to stop with error code 60, please refer to my previous tutorial HERE where I explain how to defragment an ISO image in case of error code 60:

Posted Image

3- You didn't provide anything new, you just repeated steve's method he mentioned above, so where is your point?

4- It's not me who have objection about steve's method, it's steve who is asking why the casper folder is there?and I answered him above.
thank you again all

Hi Jamal

My post in post #2 has the menu.lst code taken directly from your download in post #1.
So the menu.lst is your code and as explained it does not actually use the \casper folder on the USB drive at all.

Steve, I have no objection for your method, nor the code because it's the same I used, as I told you some of the USBs take a long time to boot, so logically in theory the code points to the files inside casper in the ISO image, but the practice shows that Grub search the real drive first and hook up the files he finds first and ignore the files in ISO, I had a similar issue with the first tutorial also with bitdefender.

hmm - that sounds an interesting 'feature' of grub4dos.

Can you explain how I could replicate such behaviour, I have a few computers around (!) so I can test it out on many of them. What would I need to do...

1. fragment the iso
2. rename the /casper folder to /xxcasper
3. test booting until I find a system that does not boot
4. Rename /xxcasper to /casper and see if it now works?

thanks

S

No, do as I did to see why, remove the 2 files in casper from the ISO and reseal the ISO image again without those 2 files and put the rest of the files as the tutorial, you would be surprised it is working.

sorry, you misunderstand. The issue here is that the /casper folder on the USB drive (not in the ISO) is superfluous and never used. You say that under some circumstances the /casper folder on the USB drive is needed. If you remove the /casper folder in the ISO I am sure it won't boot! But that is not the issue. We are just talking about if the /casper folder on the USB drive is required and if so, under what circumstances?

AFAIK in this step initrd.gz is extracted not whole iso file.(or is it?)

thats my fault , i should have mentioned this before that . i was talking about "map --mem" command which still can boot an fragmented file , avoiding the "error code 60 " message.

Steve, I have no objection for your method, nor the code because it's the same I used, as I told you some of the USBs take a long time to boot, so logically in theory the code points to the files inside casper in the ISO image, but the practice shows that Grub search the real drive first and hook up the files he finds first and ignore the files in ISO, I had a similar issue with the first tutorial also with bitdefender.


very interesting find.
I would like the experts comment on that. because this behavior looks like a bug. cause after specifying the command root(0xff). grub4dos should load the files from the mapped iso and not from any other device.

So, I see the parameter "persistent" and wonder, where this persistent data will be stored? And is there any limit to this storage. I guess that some of jamal's files contained some stub for casper-rw but it is impossible to download it anymore, mediafire link is dead.

See Tutorial 10 on my site.

You can also add bitdefender to Easy2Boot with persistence and it will keep the AV updates too. I have added a new .mnu file for E2B for this purpose.

oh, I see this ...

 

If you want the updates to be persistent, create an Ext2 filesystem using the RMPrepUSB 'Create Ext2 FS' button called \casper-rw.
Don't forget to enable the save session option in Bitdefender. Right-Click on the Desktop, Applications - Settings - Session and Startup - General - Automatically save session on logout.

 

Ok, clear now.
