Backtrack4 ISO DVD Boot error / Wicd Wifi Manager fails to load

[nam5301]

My Samsung DVDrom drive is usb and is able to boot windows XP CD, windows 7 DVD, and others. I booted the backtrack Live DVD ISO on my laptop and it worked, just not on my PC.
My computer is Gigabyte motherboard, AMD quad core CPU 3.0mhz, 4 gb ddr3

The image above is a screenshot of the error I get trying to Live Boot Backtrack 4 from startup. I am able to Live Boot Backtrack4 from a USB stick but not DVD... Not sure why, and I don't know what the error means..

Well I run my backtrack 4 from a separate hard drive but I have a problem with the Wicd wifi manager software. It doesn't load when I click it. I try to wait it out but still nothing. I would try to re-install Wicd wifi manager, but I can't do that because I can't get my wifi internet working in backtrack yet. <<<<<<<< WICD PROBLEM RESOLVED NOW THANKS, BUT NEED HELP ON ISSUE ABOVE

did you start the wicd network manager with

/etc/init.d/wicd start

??

Yes, I finally figured out how to start Wicd now thank you! but still have the boot problem :-(

After startx you'll need to run wicd-client for the taskbar icon to appear.

In regards to boot error, appears you are getting stuck in grub, so I imagine it's not loading the kernel or is pointing to incorrect HD(hd0,0) or (hd0,1) due to dvd drive being USB and not IDE, SCSI or SATA. Look into using command-line grub to troubleshoot.

=============================================

The USB Flash drive is USB, how come that was able to boot? Because I made a LIVE USB ISO and it booted.

because the USB DVD drive is sort of over USB, like a file system embedded within a file system, whereas the USB flash drive is more or less a direct partition(file system). It's somewhat difficult to explain if you've never needed to configure/install grub.

Oh, to add to this, there is something important that really screws you up with grub if you do not know about it first. grub naming convention

So that means it's impossible to USB DVDROM LIVE ISO Boot ? If anyone who read this and has been able to LIVE BOOT from a USB Dvdrom drive here please let me know how . Thanks.

What do you want to do with the liveDVD? Install BT to disk or just use BT as a liveDVD?
