Can you get into the BIOS?
After switching on there should be two areas to press, one says setup the other BBS.
BBS lets you select the boot device.
If that works you can download the MeeGo image here and put it onto a USB stick.
Then start the ExoPC and press BBS, select the USBstick, boot from it and reinstall the ExpPC.
Another thing to look into: I had a similar issue when the battery wasn't charged. I switched the ExoPC off and let it charge for 30mins and then it booted through.




the exoPc i got from GDC os wont boot up
