Lion disc recovery, couldn't mount disc.

I am trying to perform an erase and install using Lion recovery, when I come to erase my Hard Drive it tells me the Hard Drive couldn't mount. Can anyone tell me why is this and how to remount the disc before eraseing it. Thank you in advance.

It's possible there's a problem with the Recovery Partition. Is the system you're running the same one the Mac shipped with?
Launch Terminal from your Utilities menu and enter this command at the prompt:
diskutil list
Press return.
If it sees your internal disk, note the number of the disk (far left column) you want to mount.
Then, enter this command:
mount force /dev/(number of disk)
Put in the value no parenthesis.
Press Return.

Reinstall of Lion; no recovery disc

Hi all,
I'm sorry a lot of people are having issues with their installation of Lion. I really don't have any except for the fact that in the event my MBP becomes corrupt and I need to do a reinstall, what's the procedure? I hope I dont have to shell out another $30. I was hoping to copy the initial download of Lion but it was nowhere to be seen in the download folder; I guess this is a way of legitimizing copies. But that doesn't help legitimate copies.
Anyway, I think I read on Apple's site that Lion has a built in recovery requiring no Lion discs. Can anyone elaborate on this?
Thanks.

Hold down the option key on boot up and you will see recovery disk press enter over that disk then a menu pops up and it will say reinstall lion.

I deleted Terminal application by mistake, how do I reinstall without Lion Disc? I downloaded via AppStore.

Backup your user file folders to a external drive and disconnect.
Make sure you have a stable, reliable, fast Internet connection, use Ethernet cable if possible.
Hold Command R and boot from the Lion Recovery Partition, get online in the upper right corner, reinstall Lion, it will simply install Lion again and your bundled programs without touching your files or most all third party programs.

Mountain lion disc 10.8.4

how do i buy a apple mountain lion disc without having a mac to upgrade

Mountain Lion is not available on Disk. It is only available as a download by way of the Mac App Store.

Lion Disc Space Disappearing - Not sure why.

I'm sorry, I know there /must/ be a thread on this already, but for the life of me the search on this forum never seems to reveal anything until I've posted a question (if at all). So I do apologize to those of you who dedicatedly sift through each of these posts.
Since upgrading to Lion, disc space has started vanishing. I have not made any major downloads and do not have much to begin with. I already store my iPhotos & iTunes on an external (well, the bulk of them - I've not found a means of consolidating two librairies yet, would be interested if anyone knows how I can do that, short of manual pain).
Twice now, I've ditched folders that contain ~10GB (for a total of >20GB), but shortly thereafter, and without replacement files being added, the warning comes up again. It's now blocking my comptuer from operating normally.
Thank in advance for your help.
Best,
Rax

Thank you for the response. [can I parenthetically add that I hate that this forum doesn't keep you logged in & that when you /do/ re-log in, it doesn't take you to the page you were viewing? Just have to get that off my chest - one of those days, you know].
Yes, only 50% capacity prior to installing Lion, but that was months ago (indeed, it was less that that, I can only account for roughly 50% of the space used).
I understand what you're saying about TM, but I /just/ did a backup - it seems safe to say that once transferred tot he proper TM storage unit, that that info need no longer be doubled up on the hard disc . . . No? I like the feature, in concept, but suspeect it is eating my hard disc space.
Anyhow, I've booked a genius appointment with the local apple store & will report back on what they find. I'm trying to be optimistic !
Best,
Rax

Mac Mini mid 2011 kernel panic with Lion Internet Recovery

My Mac Mini froze while using Safari and watching a youtube video, so I restarted the machine by holding down the power button, then on startup I reloaded Safari, and it completely froze again. This time around, I got a kernel panic on boot. I tried booting into single user mode by holding down the shift key, but that still gave me a kernel panic. So I tried using the Lion Internet Recovery mode by holding down command-option-R when booting. The OS showed the Internet Recovery progress bar, but when it completed and the machine rebooted, I got a kernel panic again.
Is there anything else I can try to recover this machine, or do I need to take it into an Apple store to have them fix it? It's a mid-2011 model, so I don't have a DVD drive in it, so I can't use a boot disc, although I guess I could use a bootable USB, but I don't have another machine to create one with.
I figure if it kernel panics from an Internet Recovery, then that takes my hard drive and anything that was installed on it out of the equation. I've also disconnected all external devices, drives, etc, and only have a monitor and keyboard/mouse attached to it, so that rules out any other devices that might be causing problems.
Thanks for any advice
Adam

Make sure the monitor is plugged in firmly as well as your keyboard/mouse.
Try resetting the PRAM.
Reset your computer’s PRAM
It's less likely to be helpful but if resetting PRAM doesn't help try resetting the SMC.

If neither of those things work it's probably time to visit the Genius bar.

Mac mini with Mountain lion fails to load and mount the os-10.6.3 install disk

I'm trying to use the hardware test utility that should be on the applications disk. When I put in either the install or application disk the drive kicks it out again after 15 or 20 seconds. These disks will both load on my imac (late 2009) but of course won't install anything.
Is this normal behavour or do I have a hardware problem?
In addition I boot from my Mountain lion usb recovery drive but find nothing about the hardware testing utility local or online.
I wanted to test memory. Used memtest and shows no errors. I also want to test everything else too.

Thanks much folks for the replies and ideas.
Here is more info that should have been in my first post.
The mini is late 2009.
It ejects the install os 10.6.3 original disks without mounting them BUT will load and mount any other dvd or cd that I have tried video, music or data. When either of the Apple disks are inserted the drive does a low pitch vibration for several seconds then stops. It repeats about five times then ejects. No other disks vibrate this way. The apple disks for the mini do not vibrate or eject in the iMac. They load and mount normally.
I looked for an update for the EFIboot and couldnt see anything that I thought mached the mini.
I have tried the NVPRAM reset with no change in behavour.
Doing a startup with d key doesn't find the AHT. I assume if it is on the mac-HD it would be found and run.
There doesnt seem to be one on the recovery USB drive that I created.
I did upgrade from SL to ML, no erase.
BDAqua, I'm not sure what you mean, "In fact, do 3 in a row, takes a bit of time." Should I do 3 NVRAM resets in a row?
I haven't tried the cleaning kit since all other disks give no problems or errors that I know of.

Lion Internet Recovery does not work

Lion Internet recovery appears to be broken...
On my 27" i5 QC 2010 iMac when to receover via Internet I am unable to do so I tried it using wired networking first and then wireless, same lack of results on both.
I succesfully identify myself with my Apple ID at which point I'm told that changes have been made to license terms and I need to agree to them... no problem, I click on OK to view and agree... nothing happens. No new pop-up allowing me to click on 'agree', eventually the install disk selection un-greys itself and when I click on 'install' I have to got through the same circle of identifying myself and being asked to agree to never appearing new license terms...
Brialliant, yet another Apple failure. My time is money and I did not want to go through the process of re-installing SL, bringing it up to date and then going through AppStore Lion installation... I sure hope I do not get charged another half dozen times for a product I already purchased (like it happened when I initially installed Lion).
Anybody else encounter the same recovery problem? Solutions?

It looks like somebody else did run into the same Apple problem and found the solution...
https://discussions.apple.com/message/15829120#15829120
The solution is to go to AppStore on another computer and login with your AppleID. You must then agree to their new terms & conditions. The only way I knew how to do that was to try and install one of the free apps whereupon I was asked for the agreement.
My iMac is now happily downloading the install...

Lion internet recovery only shows a spinning globe

I had boot camp on OS X Lion, with Windows 7 installed. I decided that I wanted to install a third OS (Linux) so I used the partioning tool in Windows. I made sure that i partitioned the windows hard drive, so it wouldnt effect my mac side. when I re started the macbook, i had no option to boot in the mac side, the icon was gone, even the recovery was gone, so i booted into windows, only to have it give me a blue screen (which dissapeared too fast for me to read) and the the computer re started, and kept doing it over and over. so i popped in my windows 7 disk, and re installed it on the windows partition of the hard drive and when it was installed i installed my boot camp drivers (I had them on a disk) and it asked me to re boot, so i did, only to have it give a blue screen again. so i installed windows yet again, and extracted the drivers from the disk, and only installed them, but i did not install boot camp. so now i am running windows on my computer, without boot camp, and no mac side. now, part 2 of my problem. when i try to use Lion Internet Recovery, it gets to the spinning globe, but does not give me a progress bar. it just shows a spinning globe for hours, and nothing else, until i get tired and just boot into the windows side and deal with windows. when i go into "Computer" in my windows side, it shows the partition of my hard drive (320 GB) which should be my mac side, but it says that there are no files on it, and the full 320 GB is just free space. what can i do to get my mac side back?

Backup disk couldn't mount

Hi there!
I'm one of those happy Apple users that's having huge issues with Time Capsule. I've tried just about everything, but before I disconnect it completely, I wanted to shout out a question to see if anyone's got anything to advise.
I had the restart problem and Apple's support line helped me out with this, but what happened next was that it keeps Preparing back-up forever and then I get this error message: Backup disk couldn't mount.
Being a above average skilled user, but useless at more technical issues, I have no idea what this means and what I can do to fix it. I've tried some different advice given in the forums and I've also tried to contact Apple, resulting in nothing but silence from their part.
Anyone recognize this problem?
Thanks!

Has anyone had any luck returning there iMac w/ Lion? I couldn't even reconnect back to the iternet tonight w/o restarting my new iMac.... Looks like folks have been having this problem for months

Has anyone had any luck returning their iMac w/ Lion? I couldn't even reconnect back to the iternet tonight w/o restarting my new iMac.... Looks like folks have been having this problem for months & months .. The Apple tech told me that all I could do is wait for Apple to come up with a fix... Got a new router this week so that isnt' it. Would I be better off w/o this until Apple gets their act together? I downloaded the combo update 10.7.3 & it helped for about a day... yesterday I still had to manually reset the connection but now it's resorting back to disconnectiong w/o fully going into sleep mode first. Sorry to say this is a major lemon. Help!

Seems unfair... I thought I was probalby having a router problem... got a new router this week. Thst's when we realized we have a computer problem. My next door nieghbor got zero sleep staying up all night while trying to help us figure out what the problem could be. He said if it were him he would have returned the iMac / Lion. Got the new iMac w/ Lion for Christmas but didn't realize until this week that Apple is the problem.... Hard to believe that Apple just has kept on selling this like ... oh No problem! Can't stay on the internet... but will sell you another one today! I'm getting mad... It's not every day we spend that kind of money on a computer . & ALL they can give us is that LOUSY Lion combo update. I can't even stay connected long enough to make a vitamin order with Puritan's Pride... & then the disconnection wipes out my cart... so I have to start over. When are they going to fix this! 'Not feeling very positive'. I feel like Apple KNOWINGLY sold my husband a defective... system. 14 days... oh please...

Prevent Lion from automatically trying to mount Filevault 2 encrypted volume at startup?

Here's what I'm trying to accomplish: I need two separate partitions, one encrypted with Filevault 2 as a primary working partition, and a second token partition as a "decoy" of sorts, containing a pretty stock install and set as the default boot volume with automatic Guest account log on. In other words, you turn on the computer and it boots to a guaranteed sterile clean desktop. An unsophisticated snoop thinks that's all there is. A more-sophisticated snoop may notice that there's a second (encrypted) volume, but can't access anything without the password.
So I did a clean install of Lion, filling the entire SSD, and then used Disk Utility to shrink the main partition and create a 14 GB secondary partition. I then encrypted the main partition with Filevault 2 from within that logon. Then I rebooted from the clean install USB drive and installed a second instance of Lion on the secondary partition, set up the Guest account, and then set it for auto log on.
So far so good, however, every time I boot into what is supposed to be—to the casual observer anyway—the "decoy" OS, it helpfully throws up a big dialog box stating "Enter a password to unlock the disk '<Your Super-Secret Volume Name Here>'." which I then have to cancel. This is hardly helpful in disguising the fact that there is another partition on the SSD.
I've looked all over Finder's preferences and the System Preferences for a way to make this stop, but I can't seem to figure it out. Anybody know how to keep Lion from helpfully trying to mount encrypted volumes when it loads?
Thanks!

FYI, similar discusion here: http://discussions.apple.com/message/15744942
This is more of a workaround than a solution, but I ended up installing Snow Leopard to the "decoy" partition. It has no idea what to do with the encrypted partition, so it doesn't ask. Good enough for now I guess, but it would be nice if Apple made this configurable.

Vien H. Lim

Hi Vien,
Have you checked Martina's suggestion?
If the issue persists, I would like to clarify the following things for further research:
1. Please check if there exists DAG in your Exchange 2013.
2. Please check if the directory 'D:\Logs\DB01' exists.
What's more, I recommend you to use the ESEUTIL/mh cmdlet to check the database status when you create a database.
Hope it helps. If there are any problems, please feel free to let me know.
Best regards,
Amy

OS X Mountain Lion Online Recovery?

Ok so I made this huge mistake in which I literally deleted EVERYTHING in my "TOSHIBA HD". No partitions, recovery disks, anything. Luckily, I had bought Mountain Lion from the App Store before the mistake and was able to make a boot DVD BUT once it reaches towards completition, some kind of error "could not download necessary files to install OS" appears.
... and I take a deep breath and search for solutions from my phone and find this "online recovery" thing. I follow the instructions (command + F on startup) but when I finally reach recovery mode, it turns out to be Lion Online Recovery, which prompts me a Lion installation via the App Store. I never bought Lion so there isn't much this recovery mode can do for me. But then I find out there's a Mountain Lion Online Recovery and after several attempts to reach it, I keep getting the Lion one.
How can I boot in Mountain Lion Online Recovery in order to download it from the App Store and FINALLY use my precious MacBook?

While we all have MacBooks in this forum most of us don’t run Mountain Lion. There's a Mountain Lion Support Community where everybody has Mountain Lion. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_os/os_x_mountain_lion

would i be able to use the lion internet recovery since my college uses WPA/WPA2 Enterprise wifi? Im confused becasue this exact one is not listed under apples page about os x recovery.

Probably not. You'd need to go somewhere that Internet isn't on a locked-down wireless network.
See this for specifics. "It depends."
