If your HD crashes and you have a bootable thumb drive already created with the OSX on it then you can load the OSX to the new HD/SSD and boot from the usb thumb drive and be back in action.A Universal Serial Bus or USB Drive, also known as a flash drive is a portable data storage device that includes a memory which includes a USB interface. I would create the bootable thumb drive in a scenario where i am upgrading from a spinner to a SSD and the HD is still functional.
#BOOT A USB FOR MAC INSTALL#
I would install the OSX to the internal drive from the utility screen and then be able to boot up at that point and run the OSXĪlso, I see what you mean about trying to create a usb bootable thumb drive from a "crashed" HD (you can't).
#BOOT A USB FOR MAC MAC OS X#
The USB thumb drive already has the OS X on it, but because I am booting from it I cannot select it as the destination for the OSX at the Mac OS X Utilities screen when I choose "Re-install Mac OS X", that is why it is "locked" Let me see if i can demonstrate a very basic understanding of this: This is semi-overwhelming to me, but I think i will be able to get thru it (thanks to you and the other great people here)! IOW, can a HD/SSD lose its ability to boot itself but still be useable after the booting process is accomplished by the USB thumb drive? (as it relates to Question 1) Would there ever be a scenario where the HD/SSD could not boot itself and you would have to use a USB bootable drive, but you would not have to replace the HD/SSD necessarily? If a HD crashes and had to be replaced would the process then entail my creating a USB boot drive, loading the OSX on a "new" HD/SSD that i would put in and then using the usb boot drive to boot the OS X from the new SSD? If my MBP were to lose its ability to boot itself with the SSD, would the USB thumb drive allow me to accomplish this? If so, when i get to the step where the MBP asks me to select the drive to be installed "to" would i select the SSD (or a different HD) to receive the OS X?Ģ. I cannot put the OS X on the boot drive and thats why its locked. OK, so the USB that i created will allow me to "boot" the operating system, or to "load" it. I know my questions reveal my lack of intellect with this subject, but I don't let that discourage me because I really want to learn!ġ. Thank you for your time and sorry I don't get this.Ĭlick to expand.Thank you Jake. My goal is to get a usb drive that will boot my MBP in lieu of the SSD in case I ever need to. Thats where I'm stuck and after a number of hours I can't figure out what to do next. However, the usb says "This disk is locked". I then choose "Re-install Mac OS X" and press "continue".Ĭontinue again, agree to terms, agree and then I see the screen that allows you to select the disk where you want to install Mac OS X. I select the Mac OS X drive and the computer then displays "Mac OS X Utilities". When I plug that drive in and press option on a re-start I see three drives come up, SSHD, Recovery HD and Mac OS X (usb). Right now I have the the "Mac OS X Install ESD" on my flash drive which contains the "Install Mac OS X Lion", Library, Packages, private and system folders. Thats basically all i want on the usb drive. I would like to have a usb drive that will boot my 2009 MBP on demand instead of booting from the SSD that i recently installed that contains Lion 10.7.5 Ok, this is what i would like to do, i just don't know the best way to accomplish it or if it can't be done. Just to explain a bit more of what i have done and where Im stuck (I apologize for being redundant): What I'm trying to accomplish is to have a thumb drive that I can use to boot my MBP in case of a SSD failure which would not allow me to use the Recovery Drive.Ĭan you tell me what you think the problem is and is there any way to "unlock" this drive? Ive got to believe there is a way, but I have no idea.
#BOOT A USB FOR MAC HOW TO#
Ive tried to figure out by researching online how to "unlock" the usb flash drive, but no matter what I try I cannot do it. I chose to re-install Lion but when I selected the "Mac OS X Install ESD, Mac OS X, 10.7.5" usb bootable drive I saw that it said that the drive was locked.
#BOOT A USB FOR MAC PRO#
I created the USB bootable drive and all went well, however, when I plugged in the USB drive and powered on my MacBook Pro while holding the "option" button, I was presented with the OS X Utilities screen.
I wanted to create another USB bootable drive and after creating it I wanted to "test" it to see if I could use it to boot up my MBP rather than using the SSD. I recently, with your help, replaced the HD with a SSD and the performance difference has been excellent.
