xtraa Posted March 5, 2006 Share Posted March 5, 2006 can i install osx86 on my external hdd and boot off it since my mobo supports usb booting? We tried it yesterday. Install stucked at step 2. Then we decided to install it via ide, and then put the drive back in the external usb. unfortunately we had no luck with that, too. Install went fine, but after trying to boot via USB, the sequence hung at somewhere right before the windowserver was launched. So i think it depends on your chipset. We tried it with an nforce4 and amd sse2. Maybe it will work with your hardware setup, it is not looking too bad.

Suser Posted March 9, 2006 Share Posted March 9, 2006 This all depends on how the OS reacts to the USB system. Like Windows XP cannot be installed on USB media to boot from it could as well be the same issue with Mac OS. When you start windows from bootable USB media the boot sequence is handled by the BIOS. But as soon as the OS loads the USB system drivers it resets the USB BUS taking over the control from the BIOS and the boot process stops. I think the same happens here.

Fidoboy Posted March 9, 2006 Share Posted March 9, 2006 Yes, you can do it, currently i have Mac OS X 10.4.5 running (and booting) in my external USB HDD drive. I can confirm that you can do it...

Soldat Posted March 9, 2006 Share Posted March 9, 2006 Yes, you can do it, currently i have Mac OS X 10.4.5 running (and booting) in my external USB HDD drive. I can confirm that you can do it... Did you install it natively or did you go through VMWare? Link to comment https://www.insanelymac.com/forum/topic/10982-usb-booting/#findComment-72124 Share on other sites More sharing options...
Fidoboy Posted March 9, 2006 Share Posted March 9, 2006 Natively of course.... Link to comment https://www.insanelymac.com/forum/topic/10982-usb-booting/#findComment-72178 Share on other sites More sharing options...
tfgbd Posted March 10, 2006 Share Posted March 10, 2006 I also sucessfully installed it to my external USB drive. It works pretty well except that I often get the "Still waiting for root device." error at boot. To fix this, I simply unplug the USB cable, wait a few seconds, and reattach it. After that, it finishes booting normally. I assume the "Still waiting for root device" error is due to the USB drive. Otherwise, why else would it continue to boot after I unplug it. Please correct me if I am wrong. Link to comment https://www.insanelymac.com/forum/topic/10982-usb-booting/#findComment-72795 Share on other sites More sharing options...
Astro_Creep Posted March 10, 2006 Share Posted March 10, 2006 I have 10.4.5 installed on an external USB drive and once in a while I get the root device error too. The first time it happened I thought the install was hosed! I used to get this error with 10.4.3 too. I also managed to install 10.4.5 to a 4 gb thumb drive on a Dell Inspiron 9100...and I've never seen the root device error with the Dell booting to the thumb drive.

HeadRush Posted March 25, 2006 Share Posted March 25, 2006 For those who were successful with the USB booting do you want to throw me bone here and tell all what Boot loader your using? - I get no joy with the Chain0 approach also from a third party boot loader I got (BootIT NG) won't recognize HFS+ on an USB drive (cf. it apparently recoginizes HFS+ on an internal SATA PATA). TIA. Link to comment https://www.insanelymac.com/forum/topic/10982-usb-booting/#findComment-82700 Share on other sites More sharing options...
lkl Posted March 25, 2006 Share Posted March 25, 2006 I'd say the USB booting is really motherboard-dependant... I managed to set it up w/ 10.4.4 native installation. I had to disable my main internal HDD on the BIOS. If it can help...
