I've read this thread too in the past and I know it's very useful, but my problem remains, what if my PC is unable to boot from USB?
I guess my solution would have to be something like this:
- 1. Burn a mini.iso or alike to boot the PC (DONE)
2. Get to command line and somehow mount the USB drive or a Net drive
3. Make it bootstrap/install from the mounted USB/Net Drive
The only thing I succeeded was hosting the installation files on a webserver in my other PC and from the PC that I booted with the mini.iso CD chose the mirror to install from manually, but this kind of installation expects to find a certain content in the mirror, such as "Release" file and others that aren't apparently the same on the Ultimate Edition ISO file, perhaps Thee can shed some light here, could you make an "alternative" ISO file so we could mirror it and perform a Ultimate Edition net install from it? Think about it, You could add your distro to UNETBOOTIN drop down list of distros! It could save a lot of time, just install unetbootin, chose Ultimate Edition from list, reboot, get into the installer, perform a net install from the Ultimate Edition mirror and voila, you have your Ultimate Edition installed! I know this kind of installation may take a lot of time, but it's a nice solution for those that can't burn a DVD nor boot from DVD/USB.
