enb14 Posted October 23, 2006 Share Posted October 23, 2006 I have the same problem but I was trying both things GPT and MBR and none of them worked. Any one else have fixed this, my BIOS supports booting from USB so has anybody successfully booted OSX from USB?

Iksam Posted November 20, 2006 Share Posted November 20, 2006 hi guys! i´ve just installed mac os (10.4.5) into a partition of an external HD and i can´t boot mac os. I´ve tried with grub, but it says "unit doesn´t exists". Mac partition is primary and it´s activated (see attached file). Any suggestion? Thanks a lot for all!

boxtyman Posted June 5, 2007 Share Posted June 5, 2007 So, anyone cracked it? My OSX boots well with the (SATA) disk inside the mobile: same disk in a usb2 box I get a system not found message. The disk is primary and active. The BIOS says I can boot from HDD external but ...... sod all! Fujitsu bamilo 1536 dual core, 1mb ram. I 'd love to sort this as I need my XP/Vista disk for work and can't take risks. Help.
