Dear Forum Members,
First of all, I want to say that I've seen almost every thread in the web regarding to these two problems but didn't find anything, these both about installing BT4 FINAL to my usb drive.

Tools and Devies I Used:
-UNETBOOTIN
-Toshiba A200-1M5 to run LiveCD
-Kingston Flash Drive 32GB

The first method I tried was the regular <strong>install.sh</strong> bash script, which ran smoothly till I reached the partitioning part, it was formatting partition #1 in / but it couldn't mount the partition in that location "/",ohh sorry I forgot to mention that I went the Guided Use Entire Disk option.

The second method was a tutorial online (Backtrack 4 – USB/Persistent Changes/Nessus) and when I reach the <strong>grub-instal</strongl> command I get an error says that
<strong>/mnt/sdb1/boot/grub/stage1 not read correctly</strong>

So any help would be appreciated.
