010 – Boot Bitdefender Rescue CD ISO from USB

Please Note: The information below is now outdated as the linux distro used by BitDefender has been changed.

Easy2Boot can directly boot the new ISO. Persistency is not currently supported with the new 2013+ versions.

BitDefender booted directly from a USB pen using the QEMU button in RMPrepUSB

This tutorial was inspired by Jamal’s tutorial at http://www.boot-land.net/forums/index.php?showtopic=12813

It only works with 2012 or previous versions of the ISO.

1. Download BitDefender Rescue CD ISO file (bitdefender-rescue-cd.iso) from here (388MB) – this was the one I tested (388,820Kb 18th Jan 2012).

A new (2012) version which was modified to fix a licence expiration issue can be found here. See this forum thread for details.

2. Insert your USB stick (1GB or larger) into your Windows PC and run RMPrepUSB

1. size=MAX

2. Volume Name = BitDefender


4. Filesystem = FAT32 + Boot as HDD

5. Copy OS files (leave unticked)

6. Click on Prepare Drive

3. Now click on Install grub4dos and answer No to use MBR question and OK to copy of grldr file

4. Copy over the ISO file you downloaded in step 1 to the USB drive

5. Use Notepad to create a menu.lst file on the USB drive as below

 title BitDefender Rescue CD 2010
 map /bitdefender-rescue-cd.iso (0xff)
 map --hook
 root (0xff)
 kernel /casper/vmlinuz boot=casper persistent noprompt iso-scan/filename=/bitdefender-rescue-cd.iso
 initrd /casper/initrd.gz

 title BitDefender Rescue CD 2010 (select vga mode)\nSelect if the previous option displays a black screen and no GUI
 map /bitdefender-rescue-cd.iso (0xff)
 map --hook
 root (0xff)
 kernel /casper/vmlinuz boot=casper persistent noprompt iso-scan/filename=/bitdefender-rescue-cd.iso vga=ask
 initrd /casper/initrd.gz 

You should now have just three files on your USB drive – menu.lst, grldr and the iso file.

6. Restart your computer and boot from the USB drive to test it. Note: Emulators or virtual machines may not work but a real system should work.

When BitDefender boots it will start to download the latest updates automatically.

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.

For the BitDefenderRescueCD_v2.0.0_5_10_2010.iso

Extract the \boot and \rescue folders to the root of the USB drive and use this menu

 title BitDefender Rescue
 if not exist /rescue/livecd.squashfs echo No squashfs && pause && configfile /menu.lst
 set SQUASH=rescue/livecd.squashfs
 set common=root=/dev/ram0 real_root=/dev/loop0 loop=%SQUASH% cdroot_marker=%SQUASH% initrd udev cdroot scandelay=2
 set silent=quiet splash
 #set silent=
 set lang=en
 debug on
 errorcheck on
 kernel /boot/kernel.i386-pc %common% %silent% lang=%lang%
 initrd /boot/initfs.i386-pc 


If you are asked for a username and password, then you probably don’t have enough memory. Normally no username/password is required if your system has sufficient memory (approx. 600MB or more). Also try selecting a different VGA mode using the second (vga=ask) menu.


You can add BitDefender to your E2B multiboot drive with persistence by using a .mnu file.

See the \_ISO\docs\Sample mnu files\linux folder.

BitDefender 2017

On CD\DVDs and write-protected media we can use the isoboot cheat code, however the ISO file is not loaded by the kernel if it is an NTFS volume, so for a USB drive we must store the ISO on a FAT volume. In this example, Partition 2 (hd0,1) is a FAT32 volume.

Note: BitDefender 2018 (last version before discontinued) does not mount NTFS or FAT volumes – this method only applies to the 2017 version (683MB) not the 2018 version (852MB).

We also ask for the VGA mode because some displays don’t show a picture if the default mode is used.

This menu is for Legacy\MBR mode only as it uses grub4dos.

iftitle [if exist (hd0,1)/bitdefender-rescue-cd.iso] BitDefender Rescue CD (no disk writes - FAT32)\nISO must be on a FAT32 partition
 set ISO=/bitdefender-rescue-cd.iso
# comment out the next lines if you don't want it to ask the question
 set ask=N
 set /p ask=Do you want manually set the VGA Mode (Y/N) ? 
 if /i "%ask%"=="Y" set ask=vga=ask || set ask=
 debug 1
# hd0,1 is partition 2 = FAT32
 map (hd0,1)%ISO% (0xff) || map --mem (hd0,1)%ISO% (0xff)
 map --hook

 set "SQUASH=/rescue/livecd.squashfs"

Easy2Boot (E2B) is popular multiboot USB solution that also contains agFM and Ventoy. It supports both Legacy and UEFI.
Simply copy on your bootable ISO files to the E2B USB drive and boot! Boot to DOS, Linux, Windows Install ISOs (XP>Win11),
automate Windows installs, WIM files, VHD files, images of flash drives, Linux ISO+persistence, etc.
E2B is unique in that it uses partition images which allows you to directly boot from Secure Boot images (no need to disable Secure Boot or run MOK manager or modify your UEFI BIOS).
