Reinstalling os x lion

I just added a new hard drive to my Macbook and I am trying to reinstall OS X Lion. I'm curious at seeing how long it should take to dowload?

All depends upon your download speed from the ISP, network traffic, your speed of your Wifi, if it's encryped or not and how fast your processors and storage is.
Also it could be Akamai servers are overloaded in your area, thus slower on their end.
It also depends how far away the server is to your physical location.
So it does take some time, only rough estimates based on download speed and file sizes can be used.

Time Machine backup from clean reinstall of mountain lion

I have a few niggles before and after installing mountain lion. Previously using snow leopard.
I want to do a clean reinstall of mountain lion and then use time machine to restore files and folders.
I dont want to do a full restore of time machine as i dont want to restore my niggles.
When I currently go into Time machine the restore button is alwats greyed out.
I am therefore not confident of being able to restore files selectively after clean reinstall.
I must admit I dont fully understand how time machine works after reading various tips and instructions.
Can anyone help or steer me in the right direction please.
Niggles include:-
Cant run Kaspersky or Sophos
Shutdown and restart problems
Small Desktop screen in front of blue screen after leaving idle for a while
Thanks

That button should be enabled once you navigate to a backup and select something.
But it's not going to work that way once you erase the internal HD. That's because the erased drive is treated as being a different one. Since the "old" drive isn't connected, you can't restore things to the place they were saved from, via the Restore button.
But you should be able to select what you want, right-click it, and choose the Restore <item> to ... option, to get a prompt to select the "new" drive.
Also, if you don't use either Setup Assistant or Migration Assistant to put your stuff back, Time Machine will do a full backup of the "new" drive. You may be able to prevent that, by telling it to "associate" the "new" drive with the old backups, per #B6 in Time Machine - Troubleshooting

Reinstalling Ox Mountain Lion

If I reinstall Ox mountain lion will it erase all my data on that partion

Depends on how you reinstall. You can reinstall over the existing system or you can erase and install. The latter will remove everything on the volume. The former only affects the system files being replaced.
Reinstalling Mavericks, Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Install or Reinstall Mavericks, Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.

I am trying to reinstall OS X Lion

So my macbook pro was stuck on the start up screen and because of this I am trying to reinstall OS X Lion so that it can start up. It (Mac OS X Utilties) says
that my Macintosh HD and Recovery HD disks are locked. Is there a way to bypass this lock?

So in #3, you metion the Parition button, where exactly is that; also what is the mfgr.'s ID and size?
I think Kappy is incorrect with information for OS X 10.7-10.8 which the entire drive is actually named disk0.
For Snow Leopard and earlier the name of the drive maker and it's size is the one to select when selecting the entire drive for formatting.
Also I think he missed your question because that doesn't solve your issue.

Ok, first of all, you DON'T have to use Disk Utility to erase the drive for your problem and reinstall OS X, that's a last ditch effort.
OS X can be reinstalled over itself to fix it without touching most of your programs and none of your files.
It's only if there is drive corruption that the MacintoshHD partition (section on the drive) or the entire drive will need to be erased and reformatted (all data is gone)
You mentioned a "stuck on the startup screen" issue.
Can you describe what your seeing?
Are you the owner of this machine or is it managed by someone else? School/work etc.
Have you held down the Shift key on a wired or built inkeyboard while booting to enter Safe Mode?
Can you backup just your users files to a external storage drive (not TimeMachine!)?
Can you follow further instructions?
..Step by Step to fix your Mac
Tell us what you see and what you have accomplished, if you were or have a recent backup of your files off the machine or not.

Trying to reinstall OS X Lion but the only option is to reinstall OS X mountain lion is there a way around this?

I recently formatted my hard drive so that I could give my computer to my brother but when I was trying to reinstall OS X Lion (10.7) the only option that showed up was to reinstall OS X mountain lion which I do not have, so now I can't get past the menu that comes up when you hold command + C. How do I reinstall to OS X Lion when it isn't even an option that shows up

Ok, well, having had Snow leopard on it originally solves the question: the license for Lion (or Mountain Lion for that matter) is not transferable. You are required to erase the drive and reinstall the original OS (Snow Leopard). Giving or selling it with Lion (or ML) on it will not be helpful for the recipient because the machine ID and their Apple ID will no longer match so they will not be able to get updates.
Have you checked your Purchases section at the app store? Here is what shows on mine:
If you are using the recovery mode and Mountain Lion comes up, then I can only assume that this is what you purchased. I don't know why it would show up otherwise.
As far as selling your Mac, the above is irrelevant since you will need to reinstall Snow Leopard and the recipient will need to purchase Lion (or Mountain Lion) using their own Apple ID.
However, you need to check on this since you may want to download Lion again for another machine of yours. So, if you are sure you purchased Lion and nothing shows under your Purchases at MAS, I would either call Apple or make an appointment with your nearest Genius Bar to get it sorted.

I'm trying to reinstall my mountain lion, but it won't install on my regular disk

so, i have a problem.
When i tried to restart my Mac earlier today, I got the gray screen. Now i'm trying to reinstall my mountain lion, but when the install guide tells me to choose a disk to reinstall on, it says that my disk is locked.
please help, urgent!
thanks.

No, you'll lose your data. Do you have a backup? If you don't use Time Machine, here are some cloning programs you can use to make a backup. Two backups are better than one.

I encountered the same exact problem when I attempted to re-installed OSX Lion on an old laptop. The date was set back in 2000, which rendered the certificate obsolete. Here's how I fixed it:
From the recovery menu, select the Terminal application. Run the 'date' command to confirm the date is wrong, then set the correct date using this command: date {month}{day}{hour}{minute}{year}
e.g. date 1219195613
Exit terminal (type exit). Retry the installation.

Is it possible to recover erased information after reinstalling os x lion if I haven't made any backups?

We were having some problems with our iMac not starting so I searched the Internet and found That I needed to reinstall os x lion to fix the problem. Before reinstalling the program, I tried the Disc utility option to see if that would fix the problem. It said there was an error and I deleted the disc thinking that it was my external hard drive and not my computers hard drive. I then reinstalled os x lion only to discover all my files were deleted. Is there anyway I can get my stuff back? Obviously I am not great with computers and I thought my computer automatically made backups, so I never made any backups. Please help

hew, some may be recovered, but...
It may be possible to recover some erased ones, but you must quit using the Computer immediately, because the OS will think it can write to those freed blocks on the disk.
Either boot this one in Target mode...
http://support.apple.com/kb/HT1661
And recovering from another Mac, or booting this Mac from another HDD, then using Data Rescue...
http://www.prosofteng.com/products/data_rescue.php
(Has a Free Demo to see if it could or not, but you'll need another drive to recover to).
Or professional Data Recovery Services.
BUT, every second you use that Mac the chances will be slimmer.

Logic board replaced...asking me to reinstall OS X Lion, but stuck on "loading installation information" for 4 hours. What to do?

I had to have the logic board in my 7 month old iMac replaced due to the fact that my now exboyfriend put a firmware password on my iMac remotely and I couldn't get into my computer. I took it to the Genius Bar and they replaced the logic board so I wouldn't lose any of my files. I just got it back and when I turned it on, it is asking me to reinstall OS X Lion. So, after hitting continue, a box comes up telling me that they have to verify the computer's eligibility with Apple and that it is "loading Installation Information". I've been stuck on this screen for 4 hours, at a 18.25 mbps download speed. What do I need to do? Tried searching forums, but nothing really gives an answer.

Take it back to the Apple Store and make them fix it.

I wanna reinstall Mac OSx lion on MacBook pro, my problem is I dint purchase OSx lion with my apple Id before.so anybody can tell me how to purchase OSx with my apple Id on MacBook

Nope. You can purchase a Snow Leopard DVD for $29.00 through an Apple retailer or ordering from AppleCare:

Hello! Tried unsuccessfully to restore my MBP, running the Mac OSX Lion, to factory settings. I keep getting the "can't download additional components for the Mac OSX Lion" error when reinstalling the OSX Lion. Any tips on how to resolve this problem?

Hi
Given that your answer to 1. is 'pre-installed' and 3. is 'No', I think the only thing to do is to take it to an Apple store (ideally the one you bought it from) and have them reinstall it for you.
The intended solution in cases like yours is that you should be able to reboot and install even a wiped disk by using Apple's servers over the internet (you do this by restarting with 'command-r' and choosing 'reinstall Lion'). However if this isn't working for you then you need to get the store to do it. Don't let them fob you off with 'go home and try again'. Have them do it in the shop (you're still covered by Applecare warranty so it should cost you nothing save the inconvenience of the trip and possibly leaving the machine there while they fix it).
A reinstall should leave all your own personal data and programs in place.
Note for future: when you get it fixed, first thing to do is buy a cheap external drive and start keeping a backup (either Time Machine or clone with Carbon Copy Cloner).

Cannot Reinstall OS X Lion OR Restore from Time Machine

With Firevault enabled, I attempted to reinstall OS X Lion from Recovery Mode. After being asked to enter the password to unlock the encrypted 'Mactinosh HD' disk, the reinstallation began. Everything seemed fine until the install process was supposedly finished, then a window popped up explaining that there was an error and to try again. I tried again and the same thing happened. I also tried to restore from Time Machine with no success (the same thing happened). I opened Disk Utility via Recovery mode and verified/repaired the 'Macintosh HD' disk and its permissions, but the reinstall/Time Machine restore still fails. Then I erased the disk with Disc Utlilty, and attempted this again with no success. My computer no longer boots into OS X at all (it didn't even before I erased the disk via Disk Utility). It can only boot into Recovery Mode or Windows--I'm basically running a pretty overpriced Windows PC.
I am using a 21" iMac with an Intel Core i5 processor, CPU @ 250GHz, have 4 GB of RAM, and am (supposed to be) running OS X 10.7 Lion. Right now I'm using Windows 8 Consumer Preview x64 bit on a Bootcamp partition on the same computer if that matters to anyone. If there's any useful information I could provide to help you help me then please let me know! This is a pretty sucky issue that I'm having a great a deal of trouble and frustration with and any help would be very very appreciated.

Whenever I try to do this it says "Error trying to turn off encryption". The message does not offer much in the way of an explanation aside from that. Maybe that's simply an 'incorrect password' message? I entered my adminstrator password which works to unlock the drive, but apparently not to turn off encryption unless the error has nothing to do with my password. I opted to have Apple hold on to my Filevault restore key which I was too lazy to write down when I first enabled the feature, so if that is the password required to turn off encryption I suppose I'll need to call Apple Care to retrieve it. =/
By the way, the computer no longer boots into reguar Recovery Mode but now boots into internet recovery. Interestingly enough, another attempt at Time Machine recovery also appeared to work (saying that it was done successfully) but in fact it didn't.
Also, whenever I try to change startup disc to Macintosh HD it says "Error: Building boot caches on boot helper partition failed". Whenever I restart holding the Options key to view available drives/partitions, only Windows and My Passport (external hard drive) appear.

Welcome to the Apple Support Communities
Lion uses Recovery to reinstall OS X. Press Command and R keys when your Mac starts, open Disk Utility, erase the drive and reinstall Lion. The other Mac has probably got its hard disk damaged, so take the Mac to an Apple Store

Safari lion isn't loading images or some text. It doesn't even load any of the "iPod / iPad / Mac boxes on the apple page. Is there any way to fix it, or reinstall safari for lion?

I connected my macbook pro to my school network, with a proxy server, and when i got home, safari wouldnt load any images or certain text on any web page.
I removed the proxies from network settings, but it still hasnt done anything.
