How to download Lion again to make bootable USB drive?
I downloaded Lion and have it installed. Wanted to create a bootable USB drive from the .dmg file but it's gone after install. How can I download again? App Store shows it's installed and won't let me re-download.
This is not difficult and you will not have to download from the app store.
your computer has what is called a recovery partition that came with it.
simply hold cmd+R while you boot up. let go a second after you hear the chime.
you will boot into the recovery partition.
Use disk utlity to format your usb drive and then exit Disk utlity and go to Reinstall Mountain Lion.
it will ask you which disk you want to install ML onto. Choose your new USB drive.

Cant make bootable USB Drive / Ext HD
My hard drive gave out on me the other day, so i went and purchased a new one. However, my optical drive went dead a while back, so my only option to install the OS was via USB or Ext HD. I bought an ext disk drive, but i couldnt get it to run the installer when i booted up (Apple told me that installers wont work on USB ext disk drives) It DID recognize it when the computer was booted up, so i made a CDR of the Snow Leopard CD. I then looked on forums as so how to make it bootable. I cleared an ext, partitioned it, and selected GUID from options.
Now where i run into trouble is here: I went into restore and dragged the cdr to the SOURCE field and the drive to DESTINATION. nothing would happen. i researched and found out that the cdr had to be a dmg. So i converted it. Now when i did it again, i got an error. I went into "scan image for restore" to see if the dmg was the problem, and i get the error: Unable to scan "Mac OS X Install DVD.dmg."(Invalid argument).
Im assuming that i either didnt make the cdr correctly, or i converted it wrong. I still have copied of them both. Any help would be appreciated....If your optical drive isn't working how did you make a .dmg of it?
Now, what you can do is take the DVD and your external HDD to a computer with a functioning optical drive. Use the Restore option of Disk Utility to clone the DVD to the external HDD:
Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4.Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external drive.
Source means the OS X DVD.
Be sure your external drive has been prepared correctly:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

Why can't you provide specific instructions here in HT203909 (Boot Camp: Creating an ISO image from a Windows installation DVD) about how to make the USB drive bootable? The article referenced for partitioning the drive is not dedicated to Bootcamp--too long, too many options. How do you make it bootable?
If your BC Assistant shows the option to create a USB Installer, it automatically is marked as bootable. There is no need to have manual intervention to make a bootable USB. Once the process is manually modified, it is supported by the person modifying it.
You have two or three options (depending on your Mac Model).
1. Create USB... - Use a USB2 flash drive, which is erased and formatted. If your Mac supports ISOs then BCA will prompt for the Media. Any Mac which does not have a built-in Optical drive will support an ISO. There are specific Mac models which support both, DVD and USB based installation.
2. Download Software from Apple servers...
3. Install Windows...
Are any additional instructions really necessary? -
I've already downloaded and installed the LION. Is it possible to re-download it just to make a USB duplicate copy? If yes, please advise instruction.
Thanks a much!Yes. Open the Mac App Store and click the Purchases icon in the toolbar while holding down the Option key. The "installed" button will change to "install" and you'll be able to download the installer again.

How do I re-download podcasts? My external hard drive failed and I can't figure out how to download them again in the updated iTunes.
The Time Capsule drive is a network drive. You have to mount it on the desktop before you will be able to drag/drop files onto the disk. More tips are in this thread:
https://discussions.apple.com/message/17312017#17312017
.....and then delete them from the Mac to free up space?
The Time Capsule was designed for your backups.
If you move a file to the Time Capsule drive and delete the file from your Mac.....you have no backup.
Your only copy of the file will be on the Time Capsule drive. I would only do this with files that I could afford to lose.
All drives fail. When.....not if....the Time Capsule drive has a problem, you will lose your data. -
Creating a Mavericks USB boot drive after the horse has bolted. Can I create a bootable USB drive from my iMac after installing Mavericks without saving the Install OS X Mavericks.app file? Do I need to re- download the whole 5.29 Gb from the App Store again? My problem is my 4Gb/month allowance on a 12 month contract. I cannot purchase a data block from my ISP and although my speed is theoretically slowed to 64k after reaching my 4Gb, it actually ceases to download in reality.
HI tasclix, it depends what you mean by an OS X boot drive.
If you want a recovery disk from which you can reinstall (by re-downloading) or recover from a time machine backup, then nbar is correct.
If, however, you want to boot and run the OS X installer from the USB drive (so that you don't need to download again), then you will need a copy of "Install OS X Mavericks.app"; see this article:
http://support.apple.com/kb/HT5856
Before downloading again, search your system to see if the installer is still there - it's usually in the /Applications folder unless it has been deleted, but check your whole system for it anyway, you never know, you might still have it somewhere.

HOW TO DOWNLOAD T AGAIN CAUS OF I HAVE LOST my origanl mac os x and ihave lost the box of the labtop with original cd
Snow Leopard is not available for download.
If your Mac came with Snow Leopard, note the serial number, contact Apple, give them your serial number, and they may be able to send you a replacement copy (for a fee).
Note: You should always take good care of the install disc(s) which came with your Mac. I recommend making a few backups and keeping the originals in a safe location; use the backups when needed. If you have a portable Mac, always have a copy of the install disc with you, especially when travelling. -

How to download Lion to a computer already running Lion using a different app store account?
Hello Everyone,
I currently have Lion installed on my imac. A friend of mine currently has problems with his internet connection and would like me to download a copy for him. Anyway, I logged into the app store using his account but it won't let me download a copy for him. Lion just shows as being installed which is the case but I want a copy for him to burn to dvd. Do any of you know a solution to this? Of course, I could burn my copy for him but he wants his own.
Many thanks in advance.Thanks for the reply. I downloaded Lion again using my account and I have a copy of the installer that we could install on my friend's machine but we are concerned that he wouldn't get updates via the app store. This is why we wanted to purchase it for him using his account. The problem is that I can't buy it for him on my machine using his id because Lion is already running on my imac. We're trying to do this correctly and legally but it's proving to be quite difficult. Thanks again.

How to install windows 7 through a bootable usb?
I had tried to install windows 7 on my imac running os lion through a bootable usb as it's superdrive is broken.
Firstly I created the bootable usb of windows 7 from my friend's laptop using the instructions on this website
http://windows.appstorm.net/how-to/windows-7/how-to-create-a-windows-7-installat ion-usb-drive/
but bootcamp would raise an error saying disk could not be found. So I modified the info.plist file from bootcamp package contents and created an iso of the bootable usb drive. Bootcamp then allowed to create a windows install usb through the iso and partitioned the hard disk too but after doing so the computer restarted with a black screen and a message ' insert boot disk and press any key'. Now I've deleted the windows partition and really need help installing windows 7.You can only install Windows 7 from an USB drive if your Mac didn't come with the SuperDrive.
I know that you can modify the Boot Camp Assistant Info.plist to show the option to create a bootable USB drive, but the problem is that the firmware of your iMac doesn't allow it. Use a Windows 7 DVD -
Can i make bootable usb of already made recovery disks?
i have hp pavillion dv4 series laptop.I have already made its recovery disks,which i need now.But my cd/dvd reader is not working,so i want to make bootable usb of these three disks.Can i do it or is there any other way for me??
sawsank,
had it been obvious, I would not have asked the question. In a number of discussions here, people will often mention details that are not relevant to their goal, which is why I’d asked for clarification.
A Boot Camp partition can only be created in an internal disk, so Boot Camp can be ruled out in pursuit of your goal. (Once created internally, it won’t be bootable if it is subsequently made external.) Short of virtualizing Windows 7 in one of your four bootable OS X partitions, I don’t know the answer for how you can achieve it. -
Bootcamp cant make a bootable usb drive.
Hey guys,
When i try to make a bootable disk (USB) in bootcamp, it says he cant make it a bootable usb drive.
What to do?
Please come help.
Thanks!GIavelotto.
Make sure you download the instructions to load windows7 using bootcamp. I found that if you repeat the steps in the bootcamp assistant, you will find that it will work.
First have you managed to set up a USB install disc based on step 1. Second put the windows support software onto your hard drive or another USB stick. You need to copy the windows support software across to the USB install disc you made in step 1. Make sure you create a separate folder for the windows support folder.
Then you can proceed to step 3 to create a partition for Windows. I set it to 50% which created a 230 GB partition for Windows and 230GB partition for my Mac OS. You need to create a partition at least 100 GB for WIndows to have enough space for the software. You may want to increase this to 150GB to create enough storage for data and images.
I found that you had to make sure that you were successful in each of the steps to create a windows partition before moving to the next step. What mac notebook are you using? -
Can i make a bootable usb drive for os x yosemite on a windows pc?
I have a Macbook Pro 13" 2009 that I've installed a new hard drive in. How do I make an OS X Yosemite bootable USB drive (I have a 16 GB available)? I'm traveling, so all I have with me is a Windows 8 laptop. I have an iMac at home, so I expect I'll be able to do it easily there, but I have time now... Thanks.
No. You need a Mac for that.

How do I Install Windows 7 on Mac Book Pro via a Bootable USB Drive
Hi Guys,
I have a Mac Book Pro 13 inch, Early 2011 Processor 2.3 GHz Intel Core i5 (I initially had OS 10.5.8 which I upgraded to OSX 10.9.4 a few months ago).
When purchased it, I installed Windows via Super Drive (that being the only time i ever used the super drive). My Windows got corrupted for some reason 2 months ago. Hence, I removed the windows via Bootcamp to perform a fresh install. I discovered my Super Drive was no longer working.
Thereon I have been trying to install Windows via a bootable USB Drive but am failing to do so. After going through several forums, I have reached the following stage.
1. Created Bootable Windows USB Drive using Windows USB (http://www.wikihow.com/Create-a-Bootable-Windows-7-or-Vista-USB-Drive). Have used this USB drive to install windows on a DELL Computer
2. Bootcamp wasnt creating a partition for windows since no Windows Installation disc was being detected in super drive. (Solved it by downloading Toast Titanium and loading the .iso file on a virtual drive).
3. Boot menu was initially not detecting external drive, so installed rEFIt - An EFI Boot Menu and Toolkit. Now it is detecting the USB Drive.
Now when I boot from this device, it get a black screen with the message "No bootable device - Insert Boot Disk"
Request someone to please help me install windows as some softwares which I work with are windows based.smartestidiot wrote:
So my understanding is that my Boot Camp Assistant (BCA), since it does not allow USB installer, it sets NVRAM to boot from Optical Drive. Right?
Yes.
So can I change it or update it to another BCA version which supports the same??
All BCA versions drive the logic based on the Mac Model Identifier. Unfortunately there is no real workaround. .
