    Default Re: persistent USB installation problem

    i also tried to install my BT5-KDE-64.iso via usb stick. i used linuxlive usb creator and unetbootin. Everytime i boot there is the normal menu of bt5. then i boot bt5. so now when typing startx there appears some japanese symbols(?) but half a minute later i get back to console view because of a segmentation fault I am only a beginner so would this error also appear when using a dvd?

    I'm just a dabbler but the version of grub is different between BT4r2 and BT5. One possible way of getting the persistence to work is to un-install grub ver 1.98 and install grub 0.97 (I believe this is what was used in BT4r2.) In my opinion this is not the best way (better to wait for the experts to do it their way and post the results) but if you're impatient - messing with "sudo apt-get install grub" just before the instruction to run grub-install will put back the older version of grub. From there you'll still have to mess around with creating/editing the menu.lst file.

    I believe I'm able to demonstrate running persistent BT5 from a usb but my current configuration requires more modifications.

    Also for those having problems see the wiki. Unetbootin now supports persistence.
    So does Universal USB Installer, it worked seamlessly with BT4R2.

    Added Backtrack 5 and Linux Mint 11 RC entries.

    I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.

    I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.

    Exclamation Re: persistent USB installation problem

    I am having same issue, but also with live dvd boot. I am using iso gnome 32bit, and it is the same boot error with both. But the strange thing is, both usb and dvd will boot fine on initial try. Without customizing or adding anything to BT, both dvd and usb fail on subsequent boots with same debug message:

    unable to handle kernel NULL pointer dereference at 00000011

    I Have the problem that after doing "grub-install --no-floppy --root-directory=/mnt/sdb1 /dev/sdb" the menu.lst file does not exist in /mnt/sdb1/boot/grub, so when grub start from the pendrive do nothing.

    Maybe if somebody put a valid menu.lst on the wiki instructions, it will work.

    The new ISO files of BT5 is different to BT4, it has no /boot folder so not /boot/initrd.gz and not /boot/grub/menu.lst this is the problem, any suggestion to fix this?

    Like many others here, I had the same issue.

    I got tired of trying different partition sizes and playing with grub too much, so I gave up on that path. Next I downloaded Unetbootin for Windows adn the whole process worked really well, including persistence.

    I know it sounds strange using Windows to help fix this, but hey... I'm a firm believer in using whatever tools work.

    One oddity left though: I am no longer prompted for username/password. It just logs me straight in. Odd, and not right, but workable for the moment.

    Right, I think I am a "little" step closer to the persistence thing, however it is slightly messy!!

    I followed the same steps as in the Wiki to make the USB bootable and persitent. HOWEVER, with a few changes:

    Firstly - I created a BT4-R2 LiveCD and booted to that

    Then - Follow the steps from the Wiki (incl. re-partitioning USB, creating file systems) HOWEVER! - When creating the first partition start from cylinder 2. This leaves extra room for grub and avoids any "Unusually small" errors.

    Then - Mount the BT5 ISO and rsync the contents to the FAT partition on the USB key

    Then - Install grub as per usual (grub-install --no-floppy --root-directory=/<your mounted usb fat parition /dev/<your device>

    Then -Copy the menu.lst from the BT4R2 live CD to the /boot/grub location.

    Then - Edit the menu.lst to reflect the location of linuz and initrd (basically replace any /boot with /casper)

    Now try the boot.

    As I said, this has generated a few errors such as /dev/sr0 not being able to be mounted and seems to take some time booting so might not be the BEST solution. However, it works.

    I am currently trying to find out if there is a way i can NOW install Grub2 and maintain everything.

    If anyone is a Grub expert, their knowledge is much appreciated!!!!
