There used to be an issue where you could not boot Windows or the installer when using an HDMI connection. Not sure what you are using as you don't say. If you are, try using a VGA/DVI connection.
This is certainly the case with my 3 year old MacMini.

I'm using the supplied hdmi to DVI apple adapter to connect my Apple 20" LCD cinema display. I have an mini display port to DVI adapter from my previous mac. I will try with the different adapter and post the results.

Well, I still don't know what is causing this, but it is not the HDMI to DVI adapter, Just tried with a Minidisplay to DVI adapter connected to the Thunderbolt port and the same thing happens. After the restart the windows partition just doesn't boot. All I get is a black screen.

I had a similar problem recently. I am assuming that you are using an external (USB) DVD player to install Win7. If this is the case, I noticed (by trial & error) that some USB external DVD players do not allow booting up into any OS.
My solution was to use a USB memory stick (8gb+). I would imagine it could be an external USB HDD as well. I formatted it to MSDOS FAT and enabled the MBR (Master Boot Record) using OSX Disk Utility. Then, I copied Win7 files from DVD onto the memory stick. That's pretty much it. You just re-run the Bootcamp Assistant to allocate a partition for Windows and copy the Bootcamp drivers from the internet if you haven't done it already.
BTW, for convenience, I also copied Bootcamp drivers folder onto the memory stick to install Apple Win7 drivers later on.
Hope this helps.

I already tried that, with a 8Gb memory stick. No luck. I had the migration assistant format and copy the necessary windows installation files to it, but the same happens, a black screen. I don't think that it's a matter of the DVD or USB drive being bootable or not. If they weren't I would get a message saying that it couldn't boot from that drive. Nothing happens, just Black...
BTW, The external DVD drive that I'm using is a Lacie firewire drive. I've booted from it dozens of times with Mac (and windows) installation discs and recovery tools like disk warrior.

Add me to the list. Attempted to load Windows 7 onto my 2011 Mac Mini with the Apple Superdrive USB external. Just like Romeup, after Bootcamp partitions and reboots all I get is a black screen. This is just another Lion bug.

I never got my windows 7 installation to work. At the time I gave up on lion, A few days ago updated to mountain lion and gave it another go. Same thing. Windows7 bootable DVD (on external firewire DVD drive, on external USB DVDdrive), created a USB flash install drive. Nothing, just black screen. I give up. Getting by with virtualization software.
If you find a solution please post it.

Thank you for your reply.
But I don't understand, in that case, why does Apple offer to create a USB flash installation pendrive during the partition and install process? And how they ship bootcamp to install windows on Macs that don't have internal optical drives like mine? It makes no sense...

Ok, this sounds dumb but here goes. I picked up a 16 gig PNY USB stick, put my Win 7 ISO on it, ran boot camp and when it ask about the size of the partition for windows I told it to make the equal, presto Win 7 installed. Used an external optical drive to install the support software and it took. I have no clue if it was the bare naked USB stick or the size of the partition !!!
