    Hi Guys, Love the videos and the tutorials, I almost have mine down pat and working.

    Just one problem is booting the persistent usb install

    I've edited my grub menu.lst

    and then when I reboot and select it I keep getting

    Code:
    Error 19: Linux kernel must be loaded before initrd
    I'm using the BT4 Pre final and have writtent down all the instructions from the video to get a usb install.....


    Mine just isn't persistent...... in that I lose my settings every time I reboot


    any help please would be appreciated

    O.k.

    Again I have been at this for hours with BT4 PFR

    Installing to the usb and getting it to boot isn't a problem, works every time. But I would like to know why I lose everything each time I reboot???

    What do I have to add to my grub menu or partition table to make this thing keep the changes i make...

    I've searched heaps of places and some of the tutes talk of BT4beta, or BT3

    but I thought the whole Idea of installing it to the USB was to have a portable system, that you could carry with you and boot up from where you left off, as opposed to >boot usb, install tools you need>>>>update MSF> well I think you get my picture

    I'm trying to sound rude, and I apologise if I do.. really but does someone have a simple from start to finish on how to get it to simply boot and save the changes I make???? there would be a lot of noobs out there who would be looking for the same.


    cheers
    PS I really love all the work the BT team have put into this

    Hi Forget the rant earlier, I followed the tutorial one more time just for good luck and guess what.... it worked...


    sorry if I offended anyone



    yes to correct myself the usb install works fine and saves changes....... forget my rantingss

    cheers

    Hey, i also have the same problem.

    If i choose persistent mode, i get the same error.

    I am still unclear about the grub entry of that one.
    made the changes as per the video. removed the kernel line and i typed

    $ quiet vga=0x317

    After this also , same problem. not able to boot into persistent mode. still get the error 19. I have installed the grub multiple times.

    Could anyone paste the grub entries for the persistent USB. I will copy and paste it in my system.

    Thanks for useful information!

    My USB 32G flash drive contain now:
    • Mini-Xp from Hiren’s boot CD
    • Knoppix
    • Puppy Linux
    • DOS (Yes!)
    • BackTrack Live

    I've just resized my Fat32 partition and then created an empty ext2 partition.
    I followed another interesting description for USB multiboot with BackTrack realwindfall.blogspot.com/2009/10/backtrack-in-usb-multiboot-list.html

    I've done the alternative steps on a 4gb sd card, two times, step by step carefully, but I still got the same error, kernel panic - not sycing.
    the iso file md5 is correct.
    I've made the HardDrive installation, it have the same error.
    I just need to know what to do, i've done a lot so anything that let me use backtrack witout getting this error shoud me great.
    this error just appear in time-space from nothing when i'm using bt OR when i try to update.
    sorry for my bad english.

    Hi I could not try install.sh because I didnt burn the iso (I didnt have any clear DVDs and it was late in the night ) so I tried the two video tutorials to install BT4 on my 2G flash...none of them worked for me..next I tried unetbootin from windows but no success - Boot Error.
    Because I never used grub before (or at least I cant remember) but I wanted to try it so I started to search the web about GRUB install..until I found what I needed (first result from Google "grub usb install" - http www freesoftwaremagazine.com/articles/grub_intro/) and it worked..so here it is:

    I had BT3 on my other usb without GRUB so first I needed to install it - ftp alpha.gnu.org/gnu/grub/

    I didnt partition the flashdisk (I need it under win) so just formatted to FAT32
    Code:
    mkfs.vfat -F 32 -n BT4 /dev/sdc1 #sdc1 was my 2G usb
    Next copied the contents of the iso onto it
    Code:
    rsync -avh /mnt/tmp/ /mnt/sdc1/ #I mounted the iso on /mnt/tmp and the usbflash on /mnt/sdc1
    And now I copied the files stage{1,2} and fat_stage1_5 (for the FAT filesystem) from /usr/lib/grub/i386-pc/ to the usb onto the directory boot/grub
    Code:
    cp -v /usr/lib/grub/i386-pc/stage{1,2} /mnt/sdc1/boot/grub/
    cp -v /usr/lib/grub/i386-pc/fat_stage1_5 /mnt/sdc1/boot/grub/
    rm /mnt/sdc1/boot/grub/stage2_eltorito #Im not sure if this is needed but I removed it
    so by now everything is set up for the GRUB install - start grub
    Code:
    grub
    to check which drives have the needed files
    Code:
    grub> find /boot/grub/stage1
    (hd1,0)
    (hd2,0)
    I see my two flashdisks now (the one from Im running BT3, and the one which I want to set up
    To make sure hd2 is the right one I used TAB completion
    Code:
    grub> find (hd2,0)/cas #pressed <TAB>
    grub> find (hd2,0)/casper/ #and yes it is correct
    To install GRUB I did the following:
    Code:
    grub> root (hd2,0)
    grub> setup (hd2)
    That was all. Rebooted and it worked OK.

    PS: You can modify menu.lst if you want..

    Hmm..tried to reinstall it once again just to confirm the above described method works and it I failed to boot..tried several times with partitions created in win in linux but no luck, tried on 2 different USBs and even to change the disk geometrics but nothing again..Until I figure out what was the problem Im using syslinux which booted right away without problems..

    To all having trouble installing BT4PF and using this thread as a guide. I am sorry to say that I am not able to troubleshoot individual problems at the time, and will not be for at least a couple of more months (doing the CCNA and don't want to split my focus.

    Dear all,

    New to this, but not a total noobness on linux I followed the 1st method.

    From usb sda (with netbootin) I ran the LiveCD

    installed to 2nd USB stick (sdc as sdb seemed to be my hdd i wish to bypass) , where I also installed Grub on sdc1 according to step 7 of installer


    I did not remove any entry in grub menu as none seemed irrelevant.

    Thing is when I try to boot from the stick, all i get is a blinking _ (not even Grub>_prompt) and nothing happens.

    Any ideas?

    For my delima, (installing BT4 on a netbook) I'm going to need to put the ISO as is on the flash drive, add a boot loader, boot from the flashy and go from there?

    Default Problem with vista os after bt4 usb install

    This weekend I got an 8gb flash drive, followed all the instructions and it worked beautifully and i have absolutely no issues booting up bt4 off of my usb drive. Although when I shutdown the computer and then try booting it up so i can use Vista it doesn't allow me to. I get a message that says " GRUB loading stage 1.5" then it says "GRUB loading, please wait.... " then i get " error 21". I can not figure out what happened and where im going wrong but i definately need to get my vista working (as much as i hate microsoft) but all of my college work, and computer programs that i need for class are on my vista. Im lost idk what to do. please, please help me. i appreciate it soo much! thanx guys.
