Not really unless you copy the install off the partition before nuking it. You could dd out the linux partition, then reformat to proper gpt, then dd it back. This assumes the the partition sizes match exactly. You might try deleting the partitions, then adding them back with proper gpt flags, As long as the starting and ending blocks are the same, this will just change the gpt info and not touch the actual data in the partitions. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/atv-bootloader?hl=en -~----------~----~----~----~------~----~------~--~---
