    Hi,

    I have an external GPT formatted USB hard disk. It has two partitions, one for Time Machine and the other for data. Can I add another partition and somehow put the Lion installer in it so I can boot and install Lion from it? I have the App Store Lion install App.

    This is the output of diskutil list:

    Code:
    /dev/disk2
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                        *500.1 GB   disk2
       1:                        EFI                         209.7 MB   disk2s1
       2:          Apple_CoreStorage                         300.0 GB   disk2s2
       3:                 Apple_Boot Boot OS X               134.2 MB   disk2s3
       4:                  Apple_HFS Sarcophagus             199.6 GB   disk2s4
    /dev/disk3
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:                  Apple_HFS Time Machine           *299.7 GB   disk3

    Upon further research....

    As I have chosen to encrypt my TM backups, the disk has now been taken over by Core Storage. This means I cannot resize/add partitions non-destructively. So I will re-convert it to non Core Storage volume then add another partition and restore it with the Install ESD.

    That should keep me busy for a while...
