Hi I wanted to put the OS2007 HE on my nokia 770 MMC (2gb). I currently have OS2007HE installed in the internal flash and I had previously installed OS2006 on the MMC, so i figured i don't need to repartition or anything. So I carried on with the transferring of the OS. There were no errors in the process. But now, when I boot from the MMC, the white nokia screen comes up... stays there for a while and just goes back to the boot menu again. So i thought i would start fresh by repartitioning it again. Everything works until i type in "umount /media/mmc1" thats when it gives me an error saying the resources are busy or the device is in use. Anyone know whats wrong?

Yes, the same thing happened to me - you must turn off swap (virtual memory) before you can unmout.

Perhaps the easiest way to do this is to simply open card door (but leave the card in :-). Either it will pop out warning dialog that card is still used or it will turn off the swap and also unmount it for you so you can proceed with partitioning.
