mitch_de Posted November 16, 2008 Share Posted November 16, 2008 Hi, i partitioned my USB-HD (10 GB) with GUID , 1 Partition HFS+ Extended FS Then i installed OS XS 10.5.5 on it, but only the OS X with all needed .kext. Disk Utility shows 2 Partitions, 1 the hidden (EFI) one Main with OS X on. diskutil list /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *9.5 Gi disk2 1: EFI 200.0 Mi disk2s1 2: Apple_HFS USB_OSX 9.2 Gi disk2s2 I am experienced with MBR Booting (using fdisk -e /dev/rdiskX , f y , w, q) but not with that GUID. How can i get it bootable ? I tried OSXTools, EFI/FDSIK and installed Chameleon on this USB-HD. But how to set the partition aktive ?! Fdisk (is made for mbr to my knowledge) only shows one big partition, complete different to what diskutil shows. fdisk: 1> p Disk: /dev/rdisk2 geometry: 1245/255/63 [20005650 sectors] Offset: 0 Signature: 0xAA55 Starting Ending #: id cyl hd sec - cyl hd sec [ start - size] ------------------------------------------------------------------------ *1: EE 1023 254 63 - 1023 254 63 [ 1 - 20005649] GPT 2: 00 0 0 0 - 0 0 0 [ 0 - 0] unused 3: 00 0 0 0 - 0 0 0 [ 0 - 0] unused 4: 00 0 0 0 - 0 0 0 [ 0 - 0] unused The OS X Volume is OK and has all needed rights/owners What commands must i use (dd ??? , fdisk, ... ?)

nintendoguy Posted November 17, 2008 Share Posted November 17, 2008 use this combo fdisk -e /dev/rdiskX then type f 2 type w type q then reboot. if you are booting with the EFI partition, use f 1 instead of f 2 Link to comment https://www.insanelymac.com/forum/topic/136774-help-with-guid-usb-hd-os-x-1055-for-my-ga-ep-on-it/#findComment-968392 Share on other sites More sharing options...
mitch_de Posted November 17, 2008 Author Share Posted November 17, 2008 use this combofdisk -e /dev/rdiskX then type f 2 type w type q then reboot. if you are booting with the EFI partition, use f 1 instead of f 2 Thanks, i will try that. And set it to 2 (my OS X GUID partition). I tried first f 1 because i didnt seen the OS X part (GUID) 2. But sure, i didnt use the EFI (1 ) partition in DFE Mode , so its complete empty.
