or did I, since it came from my MBA? lol)įWIW the recovery slice of a Lion install can be copied to any other slice that's 650+ MB by simply using dd. (*Note: the UUID of the recovery slice can be seen on a Lion system that has said slice by issuing a sudo gpt -r show disk0 command I didn't just pull that one out of the Air. This won't destroy the data of course, but one needs to make a note of the start and size values of the partition (as shown by gpt show) before the remove and then use them when re-adding. To change a GUID partition type to Apple_Boot one needs to know the UUID - which for reference is 426F6F74-0000-11AA-AA11-00306543ECAC - and remove the partition using gpt then re-add it with the desired type. Apple_Boot is just a hidden version of Apple_HFS the recovery partition is just an ordinary journaled HFS+ volume that can be manually mounted with diskutil mount disk0s3 (or whatever slice the recovery partition happens to be). You can set it to Apple_Boot using gpt and this is indeed what hides it from GUI apps like disk utility.
