The EFI BIOS in some hardware like HP Mini 5102 doesn't support booting our MeeGo isohybrid images. Until either isohybrid or the EFI BIOS is fixed there is a simple workaround that involves modifying the image with the isohyrbid tool.
On any linux machine that has the isohybrid tool, execute:
$ isohybrid -offset 64 <image-name.img>
This modifies the isohybrid image signature inside the image to a deeper offset and allows most EFI BIOSes to properly recognize the boot sectors as plain iso9660, and subsequently boot normally.
