is there no official working guide of installing BT5R2-KDE-32 persistent USB?

[dusf345]

I have been trying to install BT5R2-KDE-32.iso to my 8GB flash drive using http://www.backtrack-linux.org/wiki/...Persistent_USB but after getting to this point, and after the computer churns for a few minutes after initially entering the command it gives errors. The input and output is below, please review.

I have the ISO mounted to /media/BT5R2.

I have read in the FAQ section I can install it from a virtual machine, or from Windows, but surely there's a supported way to install linux from linux?

I am using Ubuntu 11.10.

Perhaps the guide simply does not apply to BT5R2-KDE-32 and there is no guide for new users to install it from linux? Last time I used Unetbootin I was advised to use Persistent USB with fdisk instead...

I successfully installed BT5R2-KDE-32 with Unetbootin as per the guide on the Wiki but when running live it would take a long long time to start, seemed buggy freezing, hanging for over 10 minutes after logging off and doing a sudo shutdown -h now, and eveutally it would not start up at all.

I then downloaded BT5-KDE-32 and installed successfully using the guide at the start of this thread but it just gave me a 'boot:' prompt when I tried to boot from USB.

Tried installing BT5-KDE-32 again after confirming the MD5, but this time when trying to boot I saw:

Error: file not found

grub rescue>

I then installed it using Windows USB Universal Installer but on trying the same I would just see some information on syslinux and then a 'boot:' prompt.

I am not sure where to go from here, please advise!
