Restore Mountain Lion of a USB After factory resetting MacBook?

I have mountain lion in a Dmg file on my mac and plan on putting the Dmg on a usb.
I want to factory reset my mac, due to alot of small problems.
I was wondering, after you factory reset your mac and wiped the disc, then you go back to the menu with four options, One of the options says "re-install a new copy of OSX" . Usually, most people would go ahead and click that, and download the purchased Mountain Lion from there App Store account. The catch is i cant use the app store account that i got mountain lion off, but i still have Mountain Lion in a dmg, so what my question is...
Can/how you install a copy of mountain lion from a USB/portable hard drive without logging into App Store (and downloading it again) immediatley after a factory reset?
Thanks

What do you mean you have ML in a DMG file? Is the file you have the InstallESD.dmg? If so then all you need is to follow the link that Eric provided for Lion Disk Maker. Use that little utility along with the dmg and you'll have a bootable USB thumb drive with what ever version of ML you have.
Or simply use Disk Utility and use the restore tab and restore the dmg file to a USB thumb drive (8GB). Make sure you format the thumb drive as Mac OS Exteneded-Journaled with the GUID partition table.

Restore mountain lion from Time Machine after HD replacement?

Which key sequence do I use to completely restore a time machine backup to my iMac after HD went bad and was replaced at Apple store?
Tried holding down shift while powering on but comes up with galaxy desktop. I am afraid that I may overwrite my TM restore with ALL my data on it. thx

Be sure the Time Machine backup drive is connected. Restart the computer and immediately upon hearing the chime press and hold down the OPTION button until the boot manager screen appears. Hopefully, you will see a Recovery HD volume appear. Select it then click on the upward pointing arrow button below the icon. This should boot the invisible Recovery HD volume stored on your Time Machine backup.
Drive Preparation for Lion/Mountain Lion
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) 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 Security 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.
7. After formatting is done quit DU and return to the main menu. Select Restore from Time Machine Backup and click on the Continue button.

HT1349 can i download mountain lion to another computer after i bought it?

can i download mountain lion to another computer after i bought it

Yes. The other computer will have to be running Snow Leopard or Lion and sign into the App Store with the same Apple ID used to purchase Mountain Lion.

How to reinstall mountain lion from snow leopard after disc failure

how to reinstall mountain lion from snow leopard after disc failure

Open the Mac App Store, click Purchases, select ML, then re-download and install. However if your machine has the abillity to run Mavericks I'd just upgrade to that and bypass ML.

Mountain Lion sleep ejects USB hub/devices

I just switched to mountain lion (10.8.5) and when my MacBook Air goes to sleep on it's own it ejects my USB hub, to which my keyboard and external hard drive are connected. This was not a problem with 10.7x. Can you help?

Restoring mountain lion

I am trying to restore Mountain Lion. When I get to the screen to "Verify eligibilty" (I've done this many times before) It says "loading information" and tells me "unable to download"

What kind of startup error do you have? You will need to provide more details.
Try maybe steps described in this articles:

Reinstalling OS X shouldn't affect your data unless you will erase drive first. However you cannot predict what can happened during installation so backup would be recomended.
If you have an access to 2nd Mac, please check this articles too:
http://support.apple.com/kb/HT1661
http://support.apple.com/kb/PH10725
If you care about your data and you want to try to rescue data for you internal drive and you don't have an access to 2nd mac but you have available external Hard Drive, then you can install OS X on external drive, boot from this drive and copy files from Internal drive before attempting to reinstall OS X.
Also, please read informations in this article about fsck tool (fsck if necessary): http://support.apple.com/kb/TS1417.
Hope this will help.

Data recovery after factory reset

I have seen people write that data recovery was possible after factory reset below the jelly bean OS versions on android but iphone is impossible.
So I wonder what is security technology for data protection on iphone.
Let me know security technology. (data encryption, data fromat algorithm, whatever about data protection)

Follou-up..... reading other questions/answers on this forum seem to indicate I'll have to "cherry pick" specific saved data items from the desktop "Shortcut to System Recovery Files" --- a long process. Is there a quicker way???

HT1338 When trying to update getting (error surle error domain error-1100). It started yesterday, any help would be great. I have Mountain Lion 10.8.1 on a new macbook pro with retina display.

When trying to update getting (error surle error domain error-1100). It started yesterday, any help would be great. I have Mountain Lion 10.8.1 on a new macbook pro with retina display.

There are many people suffering from this problem right now (including me). It appears to be a server issue. Just wait and try checking for updates again tomorrow.
Some things I have heard indicate that this may be a regional problem, though what parts of the world are affected I don't know yet. A few people have been helped by deleting the following preference file (paste the path into the Go -> Go to Folder window in the Finder to locate it), though most have not:
~/Library/Preferences/com.apple.SoftwareUpdate.plist
Note that if you are trying to download iTunes 10.7, that can be found here:
http://support.apple.com/kb/DL1576
Also, note that there is no reason to be anxious to get it, as the only thing added in iTunes 10.7 is compatibility with iOS 6, which will not be available until the 19th, and the new iPhone, which will not be available until later as well. The new iTunes that was announced is iTunes 11, which is also not yet available.

Cisco 7941G phones will not boot up after factory reset.

Cisco 7941G phones will not boot up after factory reset.
The following happens.
1. Speaker light lit (Green)
2. Phone displays a firmware upgrade page (see attachment) for a few minutes. (Doesn't seems to be upgrading, but it "saids" upgrading)
3. Saw Cisco logo with a Java Powered page.
4. The whole thing loops again and again...
I think the reason why the phone isn't booting up is because the phone needs to know where to find the configuration/firmware files from a tftp server. I do have a TFTP server, but normally I need to go in settings to change the alternative tftp server, but the thing is that now I can't even press the settings button...
Please help.

How many phones were reset and upgrading at one time? What is the setting of the TFTP Maximum Serving Count (Advanced TFTP Service Parm) on each of the TFTP servers?
Sounds like too many devices trying to use TFTP at once.

Time capsule setting up problem after factory reset

What's the next step after factory reset to set up my time capsule again???
i did factory reset for 4-5 times and i cant use my time capsule to create a network, join an existing network or anything else.
i also tried normal reset but still nothing can be done.
There is always a message at the end " an unexpected error occured. Try again"

Plug the TC into the computer by ethernet..
Make sure the computer has no other network running and nothing else is plugged into the TC.. just TC Lan port to the computer ethernet.
Now press reset and open airport utility.
Generally you will have no issue once it is isolated. Do the setup and then you can disconnect and put it back in the network.
If it doesn't work, is the LED on the TC flashing amber or what??
Is the ethernet port connectivity LED on?

Recovering data after factory reset (security issue)

Hello there,
Recently a friend of mine asked me how to erase all data on an iPhone ? I pointed to him to "factory reset".
Now, I see a bunch of websites that show how to recover data after factory reset using their software, not sure if they work as advertised or not.
What I would like to know is if the user wants the data to be erased and non-recoverable, is this the best option or if there is any other option available in iPhone that can make the data un-recoverable. We want to make sure the data is un-recoverable after factory reset.
thanks
Ashish Shah

unfortunately this doesn't answer my question.
I do know the option to "erase all content and settings" in iPhone.
What I want to know is to make sure once done, no one can recover that data back. Since this phone will be sold off to some stranger, we don't want them to have access to the data.
Here are a few websites from my just preliminary search results that show how to recover data.
just google "extracting data after factory reset iPhone" and you will see a bunch of websites offering their products to recover. So I want to check if this is so simple, how can we really make sure the data is wiped off clean.

I had to reformat my early 2008 MacBook and have now lost Pages/Keynote/Numbers. I tried to repurchase only my OS is incompatible and Mountain Lion OS will not run on my MacBook. Really annoyed as MacBook is in good condition but now useless to me.

Help please!

Any OS version of 10.8.4 or later has all features that are not OS depended. The plugins are one example. You probably haven't updated all versions of Logic Pro X to the latest one.

Just updated my iPad 2 to OS7 and now I can't connect it to iTunes 10 on my MacBook OS 10.5.8 My MacBook can't be updated to Mountain Lion as it is early 2008 white MacBook

Just updated my iPad 2 to OS7 and now I can't connect it to iTunes 10 on my MacBook OS 10.5.8
My MacBook is too old and can't be updated to Mountain Lion as it is early 2008 white MacBook.
It all worked perfectly prior to updating the iPad 2 to OS7.
There were no cautions or warnings
Are there any work arounds?
Can I uninstall OS7 and go back to OS6?
Rediculous thing is I can connect to iTunes on an old PC of the same age

Again Apple fails to provide backward support for its own products.
I could go to the trouble of hacking the MacBook and running Mountain Lion and iTunes 11 that way
I think I will just move across to a PC as a result of this Apple strategy and I think I will just give up on Apples short lived product strategy.
A laptop that lasts five years indicates a long lived product strategy. Where they go wrong is to prevent backwards strategy when someone genuinely cannot live with ios7 like you. even the "unsupported" downgrade has now been blocked.
Don't go windows, you will not get five good years from a dell or an asus. If you can't buy Mountain Lion for it, get a new macbook, enjoy.
