Live USB "Remove disks or other media, Press any key to restart"

[eddy556]

I've installed the ISO to an external USB disk drive by following the instructions in the HowTo. However when I reboot I get the following message:

Remove disks or other media
Press any key to restart

No bootable device

There is nothing in the CD/DVD drive.

Windows then proceeds normally. I have checked the MD5 hash and googled for hours, can anyone point me in the right direction?

So the md5sum is correct?
Also do you have usb set to boot in the bios?

[eddy556]

Yep the md5 is correct and the BIOS option has USB the first in the order of boot devices. The USB drive being used is a 160GB drive and since FAT32 will only support up to 32GB I have a single partition thats primary and set to active which is 32GB. Would this be possibly causing any problems?

In addition to the above this message is also displayed:

"PXE structure was not found in UNDI driver code segment"

Research suggests flashing again, so I formatted the drive and re-downloaded backtrak final iso (again checking the md5) but still the same problem, any ideas?

Seriously no one else has come across this? This has got to be a reasonably common problem?

This has been covered and discussed before. It's just a shutdown script that is run that asks the user to remove any disks. It can easily be removed.

Thanks for the info. Do you have any links or hints etc in relation to my problem? More than happy to research for myself otherwise I wouldn't be here.

[SLK001]

Okay... Take my hand...

Edit the file "casper" located at /etc/init.d.

Comment out the echo "Please remove disks..."
Comment out all the commands of the "if" statement below the echo command, including the "fi" command.
Comment out the "read x: blah, blah, blah" command right after the finish if command.

Save "casper".

You are done.

Thanks - much appreciated.

I assume I can edit this file in windows? Since I can't boot backtrack....

Also I'm a bit dubious as to why this is happening - this should be a brand new copy, which I assume wouldn't need the manual editing of files? Is there just something wrong with my system? Should there be a bugfix for backtrack?

I'll post back once I've edited the script with the result, but I'm at work at the moment.

Hi i had the same issue last night, i used this application hXXp://www.pendrivelinux.com/downloads/Universal-USB-Installer/Universal-USB-Installer-v1.6.9.exe, after a short 10 minutes Backtrack4 was installed and booted with no issues from usb. i then installed backtrack4 to the laptop with no issues. I hope this helps.

this is how i got it to work if you need to know.
1. Plug the usb key in windows
2. Run Universal USB Installer
3. From the drop down list select BackTrack4
4. Format the USB key in Universal USB Installer.
5. Allow the iso to be installed to the USB key.
6. Reboot should be all ok.
