Install Over Debian While Its Running

[Littlehawk]

I am having a problem with installing. For some reason, I can't boot from a USB, even though the stick will boot on another machine. I can't install Ubuntu using PXE, because it hangs up due to a hardware error message. I have one hard drive and no other means to install.

However, I was able to install Debian using PXE. Now I want to replace it with Ubuntu. I can now read the USB, which has the Ubuntu LiveCD copied onto it.

Is there a way to start the installation now from the USB once I have booted into Debian? I would prefer to either completely replace Debian or repartition without losing Debian (it uses the entire hard drive, after using the guided install).

I have grub installed.

Thanks,
Jim

Have you consider:

Unetbootin looks like just what I need, but it's not working. I'll continue give it, but any suggestions are appreciated. Here is the terminal output when I try to run it:

me@debian:~/UnetBootin$ su -c ./unetbootin-linux-191
Password:
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
./unetbootin-linux-191: symbol lookup error: ./unetbootin-linux-191: undefined symbol: _ZN9QListData7detach2Ev

I installed all the packages beginning with libqt4... It's not clear what the dependencies are and which is on top.

Try this:

Thanks, I'll try those. In the mean time, I decoded what I needed to do for booting from USB and successfully installed from LiveCD running from the USB.

I'm in business!! \\:D/
