Install.sh not working with USB (FIX Included)

[alacrityathome]

See http://forums.remote-exploit.org/bac...-tutorial.html for a possible bug with Install.sh

Either using a live CD or a live USB and then using the Install.sh command, sometimes the long process of applying a persistent BT4 Pre-Final is successful EXCEPT for the grub installation.

You can tell if this is the case if you attempt to boot into the newly minted persistent usb and just get a blinking cursor after booting.

If so, do the following:

...Before logging out of BT4, pull up an xterminal and type in:
...mkdir /mnt/sdb1
...mount /dev/sd1 /mnt/sdb1
...grub-install --no-floppy --root-directory=/mnt/sdb1 /dev/sdb

then

...nano /mnt/sdb1/boot/grub/menu.lst

and adjust menu.lst

then

...unmount /mnt/sdb1/


Or, more simply forget install.sh and use the BackTrack USB Install video here:

Backtrack 4 USB Install - Offensive Security


Hopefully, this bug will be fixed in the BT4 Final.

hey,

my installer crashes when he wants to setup the grub. i think its the same bug you are talking about.

when i follow your steps, i get an Error 15: File not found

i just edit the line with persistan and add the vga attribute.

any ideas?

Hi Peter,

Do you have a little bit more info?

Are you installing to a hard drive? Or, to a usb?

Did you see the "advanced" menu item in Step 7?

You have to be careful for grub....sda...sdb...sdc.

Does everything else besides BT4 work? Boot up ok?

Sometimes if you missed any of the items above, grub is installed in the wrong place.

To avoid that, do a sudo gparted to see exactly where you are installing.

Let me know if any of that helps.

i am installing bt4 pre on an usb 8gb stick.
everything is fine and i choose the correct device (sdb).
after installing i follow your steps, reboot without cd and boot from usb.
the grub bootloader splashes up and i can take a boot option.
i only add the vga parameter to the line (like in the video link you posted).
on every menu item i pick the error 15 comes up ... really bad...

i installed the grub (in the step 7 - advanced) to /dev/sdb)

peter,

sounds like you are close. you may want to google on "grub error 15". here is one item from google ...

GRUB error 15 ( Debian/Ubuntu ) « Just a thought

so, your BT4 can not find a file it is looking for...which means the menu.lst needs to be adjusted to point to the right location or some other file like vmlinuz or initrd is not where the menu.lst is looking.....

can you post your menu.lst, and i or others can compare it to the one we have...

here is menu.lst in my BT4PF usb:

default 0
timeout 03

color cyan/blue white/blue


splashimage=6ce51d57-df27-45cc-89b7-508f83a26083/boot/grub/splash.xpm.gz

initrd /boot/initrd.img-2.6.29.4

And, also look in your boot directory and make sure the initrd.img-2.6.29.4 and vmlinuz-2.6.29.4 files are in the directory.

I am sorry to say that I can't recreate this problem. I have tested and get it functional everytime (tested on eleven different drives).

MD5 check you bt4 pre final download.

Persistent : Your VGA Attribute is not the correct one for your Video Card, try using "normal" and see what it happens then . . .
