Cant reinstall osx lion on new hard drive

I recently have been having problems with my 2007 Macbook 2,1 (yeah, I know it's old but it works...or worked anyway) taking forever to boot up. So, I backed up all of my data to an external drive, erased the drive and then attempted to reinstall osx lion (which was the current os on the machine prior to erasing) via the internet recovery option as I no longer have the original start up disc. The progress bar gets all the way to the end and then just takes me back to the main OSX utilities page. Tried reformatting the drive again and same thing. So then I resorted to creating a bootable thumb drive. I booted back into OSX utilities via this drive and tried to reinstall this way only to get an error message that it cant download additional files needed to install osx.
Next up, I used a borrowed mac, redownloaded the OSX installer from the app store and installed it on an external drive. I then booted my machine from the ext. drive into OSX lion, downloaded the installer again and attempted to install it on to my HD only to get an error message that the file may be corrupt or may have been tampered with. At this point, i went to the Apple store. The guy ran some checks but ultimately was also unable to reinstall the os. He even tried going back down to 10.6.8. So he told me this was a sign that the hard drive was bad and that they have no way of actually diagnosing it on a machine that old.
So, I went and bought a new WD 320G internal drive to replace the "bad" one in the machine. I then went through all of the steps above again and still have had no luck getting the os back on the machine. So at this point I am at a total loss. Is the computer just dead or is there anything else I could possibly try?

Did you prep the new drive correctly? You also need to install Snow Leopard on the new drive and update it to 10.6.8.
Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then 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. 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 Apply 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.
In the following you can skip the part for partitioning and formatting if you've done the above already.
Clean Install of Snow Leopard
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

ITunes wont open, cant uninstall, cant upgrade, cant reinstall. please help

recently, itunes decided not to open. no error message, no computer lockup, just not open. so when i tried to reinstall via add/remove programs, the installer opened, and acted normal, said it was validating install, then when it got to removing old program, it froze and a windowsey-looking error message popped up saying that "the feature you are trying to use is on a network resource that is unavaliable" "click ok to try again or enter an alternate path to a folder containing the installation package 'itunes.msi' in the box below" [dropdown+browse button]. the dropdown lists 2 file paths one being in the temp files in mydox and the other being in some application cache files in some system folder. neither works.
please help! im stuck! i have tried uninstalling, reinstalling, repairing, downloading the most recent and trying to install that, and even downloading an older version, and i all get the same error message.

with those symptoms, let's try the following procedure.
first, head into your Add/Remove programs and uninstall your QuickTime. if it goes, good. if it doesn't, we'll just attend to it when we attend to itunes.
next, download and install the Windows Installer CleanUp utility. use it to clear any existing itunes and/or QuickTime installation configuration information from the PC.

next, use the the following document as a guide for manual removal of leftover itunes and quicktime program files:

now try another itunes install. does it go through properly this time?

MAJOR HD PROBLEMS..disc cant be deactivated, trying to reformat and reinstall osx

As the title mentions, I cant seem to partition my HD in order to properly reformat and then reinstall osx..
I basically want a fresh new factory macbook with the original lion osx (dec 2011 macbook)..
Reasons why its not working out:
Macbook when turned on goes automatically in the options menu with reinstall os, DU, seek help online and set back a time machine backup (dont have)..
Already erased my hitachi 500 gb HD and the Macintosh HD partition a couple of times (on fastest way setting, and once in the 3 times overwrite setting which took 4 hours, not tried the safest 7 times overwrite way..)
Did a control disk with DU sometimes its fine and sometimes an error pops up saying it cant be fixed.
After trying to reinstall an os mavericks in this case, after 4 hours or 3andahalf it restarts itself in the same options menu (DU, reinstall, seek online help, time machine)..
Partitioning again wont work because the disk cant be deactivated. .
What to do guys? ?

In order to repartition the drive, you can't be using it as any kind of boot drive. That includes Recovery Mode since that is a hidden partition on the drive. So the OS won't let you remove the drive its currently started up to out from under yourself.
Restart in Internet Recovery Mode by holding down Command+Option+R so the Mac is running from the firmware. You'll get what looks like the same work screen as the regular Recovery Mode, but you'll be able to repartition and completely wipe the drive. Then install OS X. The version of OS X the Mac shipped with will be installed.
Do not upgrade it to any version of OS X past that, or the new owner will not be able to reinstall any upgrade since it would require your App Store ID and password to do so.

For future reference, unless you're trying to protect classified government documents, or other highly sensitive data, there's no reason to do any more than a one pass erase. It takes expensive, specialized hardware and software to have even a slight chance of recovering data that has been written over even just once. There's no software consumers can buy that will recover anything from such a drive.

I just restarted my mac then suddenly when it boots,disk utility came and says different option like repair disk, get help, reinstall OSX and I tried to click disk repair but it says that I am um able to repair the disk

It sounds like your hard drive either has a software problem that Disk Utility cannot fix or that the HD has failed (mechanically).
Your Mac may have booted either to your recovery partition or to internet recovery in an attempt to repair the drive- I can't tell from your post.
I'll assume that it was the recovery partition.
Try to boot into internet recovery (hold down option command R at restart), and see if you can repair your HD with Disk Utility. You should also repair permissions while you're there.
If that doesn't work, try to boot into single user mode (restart, hold down ⌘S until you see a black screen with white text) and repair your hard drive. Here's a reference with directions: Repair Your Hard Disk in Single User Mode | Everything Macintosh
If that doesn't work you have a few options:
If your mac originally came with installation disks, you can try to boot from the installation disk and then see if you can repair the HD.
There is a small chance that Techtool Pro 7 will be able to repair your HD if Disk Utility can't.
If none of that works then your HD has probably failed and will need to be replaced, which is not too difficult to do yourself if you can use a screwdriver.

I tried restoring my iMac 27" slim. I followed the steps erased my data then to reinstall osx mavericks. Now that I'm trying to reinstall osx mavericks for whatever reason it doesn't completes. Can you help me out?

That's not quite the proper way as far as I can tell. Usually, one boots directly into the Recovery HD using COMMAND and R keys at startup. If you cannot do that then most likely there is a problem with the hard drive. Since this is a new computer i would make a Genius Appointment and take it in for service.

White screen of Death. Reinstalled OSX Maverick but data is missing. HELP!

Help! i had a white screen of death on my iMac. Did a check via disk utility and the hard drive seems to be fine. I have partioned the hard drive into two volumes previously.
However, when I tried to reinstall OSX Maverick on the first partition, where it was originally installed, it was pointed out as being full and I was forced to reinstall it on the second partition. No problem with that.
However, when I start up the iMac, there are no files to be found. And this is really very upsetting to me as they contain memories of my family which I really treasure.
Am I doing anything wrong? When I go in to the set up utility and try to select partition 1, it will still give me the white screen of death and that the disk is full
Kindly advise if there is anyway for me to "force" install it on partiton 1 and regain access to my files.

If you reinstalled onto the second partition and used the same username/password combo for your admin user account, then you can boot into the voluime, open up the original volume, and drag your data from it to the same places on the second volume. To reinstall, you need to remove stuff from the full volume.

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page).
http://majorgeeks.com/download.php?det=4459
Here's a screenshot showing the particular links on the page that you should be clicking:
After clicking one of the circled links, you should be taken to another page, and after a few seconds you should see a download dialog appear for the msicuu2.exe file. Here's a screenshot of what it looks like for me in Firefox:
Choose to Save the file. If the dialog box does not appear for you, click the link on the page that says "CLICK HERE IF IT DOES NOT". Here's a screenshot of the page with the relevant link circled:
When the dialog appears, choose to save the file.
(2) Go to the Downloads area for your Web browser. Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Help! 13" macbook pro will not boot. Tried running disk repair from HD recovery, not repairable. Trying to reinstall OSx Lion, says disc is locked. Do I have to erase the drive and lose everything? I also have Bootcamp installed, will boot to Win OK

Tried running disk repair from HD recovery, not repairable. Trying to reinstall OSx Lion, says disc is locked. Do I have to erase the drive and lose everything? I also have Bootcamp installed, will boot to Windows no problem.

Hotrodmkviii,
try rebooting in Recovery mode, but when you reach the Mac OS X Utilities menu, run Terminal (from Utilities in the menu bar) instead. Inside the Terminal window, give it the following command, and then press the Return key:

Please include in your reply the output from that command.

Help/Question with Reinstall OSX 10.2.1 on iBook G4

First off...I just want to say that if someone can take the time to assist me I would appreciate it more than you know! Now...on to my issue:
History:
I have a iBook G4 running, I think on either 10.3 or 10.4 (I can't tell you now because it won't start up). I have the discs for 10.2.1 that came with the computer. I purchased my iBook from a roommate of mine a few years back and before selling it to me he loading 10.3 or 10.4, and I don't have those discs.
I was having an issue at start up...It would load to the point where I could see the picture I had on my desktop, and the dock would come up. Then it would stop and none of the icons on my desktop would show and neither would the menu bar at the top of the screen. When I clicked on an application in the dock, it would not load...the computer was trying (you could hear it) but it never would load it.
So, I did some online searching (using my wife's MacBook...yes, I wish we had two) and used the disk utility to verify my disc. It said the "keys were out of order". So, I clicked repair, and it said that it repaired "Book B" (at least I think that's what it said).
So, I restarted my computer, and now it comes to the gray screen with the clear spinning thing as though it is about to load. It sits there a while, and then just shuts off. So, I tried to reset the PRAM and that didn't do anything either.
Problem I now have:
I am now to the point that I am thinking I need to reinstall OSX...as said, I have the 10.2.1 discs that came with it upon purchase, but I know my roommate upgraded me to a newer version. I have lots of documents on here that I don't want to lose (and programs I don't have the discs for) and I plan to choose the "Archive and Install" and "Preserve User and Network Settings" Options.
Questions:
Is this what I should do?
and if so...
Will installing an older version than what I currently have any negative impact on the install or in me keeping my current documents and programs?

DiskWarrior is the only application that "can" fix this problem, but there is no 100% guarantee. You need to get the DW CD & boot from the CD to fix the problem.
Look at these links about DW.

http://www.jimarnold.org/blog/2008/10/keys-out-of-order-on-macbook-diskwarrior-t o-the-rescue/
I assume you don't have a backup of your hard drive, or you could just erase the hard drive & copy the backup files to it. Your next investment should be to buy & use an external hard drive for backup. You can get one for about the price + of DW.

OSX Reinstall DVD Help

I need to reinstall OSX but have lost the install DVD. I either need a replacement or a download to make my own. Is it possible to make my own? I know you can with Windows, don't know about OSX.

Call AppleCare for replacement disks:
http://www.apple.com/contact/phone_contacts.html
The elements are too scattered to build a replacement DVD.

Reinstalled OSX now can't activate QUICKTIME PRO

I got my powerbook about 2 months ago, and it came with quicktime pro. I recently reinstalled osx but cant activate the qt to pro. My registration used to say apple customer or something similar.
Im kinda stuck so if anyone can help i would really appreciate it.
David

David, welcome to these discussions.
I've never heard of Apple shipping the "Pro" upgrade of QuickTime on anything.
It does come as part of their "high end" Pro applications such as Final Cut and DVD Studio.
Have you re-installed those apps? I don't think they use a "printed" registration information and the "Registered to:" name is / (was?) Pro User.
You may find a Software Update is also needed for the special "Pro Apps" software.

Cant reinstall osx, help!!!!
