Trying to format and reinstall (lion download not working)

Recently finder completely stopped working so i decided the best option was to just reinstall OSX lion, I didnt recieve an install disk but noticed there was an option to reinstall on the start up disk menu.
I have erased all of my partitions and i am trying to download the lion installation to my ssd, it runs for about an hour and 30 mins then fails. I am relatively new to Macs and have inherited this one, so please excuse if my terminology is a bit sketchy.
Any suggestions?

From the Installer menu bar in Recovery, select
Window ▹ Installer Log ▹ Show Errors Only
What error messages are shown?

Erase hard drive and reinstall Lion

Hello Everybody,
Is there a straightforward way to erase the hard drive of my imac and reinstall Lion. I have purchased the mac from my friend but I believe the HD hasn't been completely wiped as I can still see some of his files.
OSX Lion was purchased and installed but is there a way to completely delete the HD, reinstall Lion and start with fresh computer?
Thanks!

I'm in the same boat but a slightly different twist. It appears, from talking to Apple support, that MobileMe corrupted some of my data on my iMac. Everything is backed up. It appears that some of the preferences have been corrupted because my scrolling doesn't work the way I set it. MobileMe propagated this corruption over to my Macbook Pro but I'm living with it right now. I turned MobileMe off on my iPad2 and my iPhone. I'll go and correct the issue but then the incorrect will turn itself back on. Even repairing permissions fixed stuff and they came back later. I chose to reinstall Lion. I booted CTRL+R, chose ERASE with the correct Mac format then double checked everything before reinstalling Lion. NO LUCK. Lion comes back but like the person above said, there are files still there so ERASE doesn't ERASE EVERYTHING. I still have issues with my preferences. I've installed the Lion Recovery Disk Assistant and have it loaded on a 4gb thumb drive. Now what I want to do is erase...blotto...flatline...zap... you name it, I want it GONE. Then I want to format and reinstall Lion from a totally naked disk drive. Anyone have any ideas? Thanks very much. It was right here that I found out about the Recovery Assistant!

Reinstall doesn't broke the warranty, so you can reinstall OS X Mountain Lion

Full format and reinstall of Lion.

Ok, so I fancied a full format and reinstall of lion - it has an SSD and I wanted to restore it to it's peak performance, while removing all the junk it's acumulated and hopefully fix it's slow wake from sleep. It doesn't have a recovery partition either (blame ccc) so I started up internet recovery and formatted it (I had of course been backing up with time machine). First problem: no FULL format option! Ok, annoying, but I can at least get a nice clean install... second problem: apple can't verify that I own lion (or something to that extent). I didn't buy lion on the store, it came with the computer, so that's probably why, but I really expected better from apple. I was left with one remainin option: restore from backup, which it's still attempting now. Once I've hopefully got my mac to pretty much the same situation I started at, is there anything else I can do? Should I do the same again but just reinstall Lion immediately, instead of trying to format it first?

"In this you can access disk utility and erase your HDD if you want a clean slate." Yes but there are two types of clean slate: the one resulting from a "quick format" and a "full format". The quick format doesn't delete anything, but merks all info as unwanted. This is fine for HDD's as they can just overwrite it, but this is the process that drastically slows down SSD's - they have to read the data, erase it, then write the new data whenever they want to rewrite it, and this kills write speed. I therefore really need at full format. It isn't a bad cable: that's mainly a problem with SATA III drives. It is a MBP not Air. But I DID have to verify my copy with apple... don't ask me why it didn't work. I don't have a recovery partition because I origionally used Carbon copy cloner to clone the HDD onto my SSD, which I now use for time machine backups.

How can I format my primary HD and reinstall Lion?

So my iMac has been running very slowly lately, and I've had some tech issues (see the fruitless help thread at http://hintsforums.macworld.com/showthread.php?p=634569), so I'm tempted to just wipe my hard drive clean and reinstall Lion.
I have a backup HD, so I should have sufficient hardware to do this. I just have a couple questions about the mechanics:
1. How do I format my primary hard drive? I assume this is straightforward.
2. Is it possible to reinstall Lion without an install CD? I downloaded Lion off the App Store, and I'd hate to think that because of that I'm stuck with the installation I have.
Any advice would be appreciated. Thanks!

OS X Lion: About Lion Recovery
Summary
OS X Lion includes a new feature called Lion Recovery that includes all of the tools you need to reinstall Lion, repair your disk, and even restore from a Time Machine backup without the need for optical discs.
And buried in the link is also this:
the storage device to use the GUID partition scheme and the Mac OS Extended (Journaled) format, which are required to install Lion
Formating a disk is done with Disk Utility.

Is it safe to format and reinstall partition while using bootcamp?

I've got a macbook pro running OSX 10.9. Currently, I have my drive partitioned using bootcamp. I would really like to format and reinstall the apple side of my partition without doing anything to windows side. Is there anything to be worried about or will the formatting and reinstilation be the same as normal?

It will not disturb Boot Camp. Do this:
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.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Blue screen keeps popping up, format and reinstall did not fix problem

My wife has a Toshiba Satellite A55-S3063 Laptop with Windows XP Home. After we got married in 2008, I noticed SP2 was installed and there was an update ready. She said SP3 never installed and I couldn't get it to install. Even with Registry checks, removing anti-virus, and other suggestions from the MS site, I still couldn't get it to install. I told her we would do a format and reinstall "someday." A month ago, the blue screen of death started coming on regularly and the computer would restart quickly after flashing the blue screen. I did a System Restore from a previous point, but a few days later, it started happening again. I decided to take this opportunity to do a format and reinstall, so I backed everything up. Her computer came with a recovery disk that only gives you the option to do a format and reinstall, not a recovery like I've done on other computers. So the format was really our only option. I did this and installed all the Service Packs (including 3). I put a new battery in (that we hadn't used before) because the old one didn't last very long and I got a blue screen and restart the next time I turned on the computer. AFter that one time, it worked fine the rest of the day. The next day I plugged in the external hard drive (Simpletech 500gb) to move her info back over. A few minutes later, blue screen and system crash. On restart, same thing. Next restart, just a black screen. I decided no big loss if I reinstall again, so I reinstalled again. Now I just get the blue screen during setup. Right after I type in the computer name and click "Next" I can hear the hard drive spinning and then the blue screen and system restarts. The blue screen is not up long enough to read, so I can't give you an error message.
I can only assume this a hardware problem, but I don't know what or how to fix it. We have her sister's old computer which is the same computer, bought at the same time, but stopped working years ago. So with explicit instructions, I might be able to retrieve hardware from that. Except the hard disk; her sister kept that and is using it as a small external drive.

this link should give you some info on how to get it open to everything

How to format and reinstall OS on mbp late 2009

I have a mac book pro with Boot Camp that also runs windows. I upgraded to Lion and somehow it crashes the mac side peridoically. I am told I need to "clean" it and reinstall lion using the recovery drive. will that delete the windows partition too??

I have a mac book pro with Boot Camp that also runs windows. I upgraded to Lion and now the mac side crashes/freezes periodically, especially iphoto. I am told by the genius' that I probably need to "clean" it and reinstall lion using the "recovery drive" which resets everything back to default and reinstalls the lion operating system. My question is will this also delete the "windows" partition drive and all that data too. If so that will be a huge pain in the ___ to back up and reinstall boot camp and windows. I want to shoot the lion.

There is no system like Acronis for the Mac platform. You can try using the buiilt in Disk Utility to create an Image of the complete Mac drive but I have found that this does not work very well as on tryiing to restore it gives errors sometimes.
You can use SuperDuper or Carbon Copy Cloner to create a bootable Clone of your system partition. But that is only for the System partition and not the complete drive.
If you use Boot Camp to install Windows on your Mac neither of those two programs will clone the Windows side.
Neither will Disk utility as Mac's can not create or write to a NTFS partition. So some other program is need for that.

How do I get out of kernel panic? kernel panic upon boot. I did that hard drive cleanup and reinstalled Lion. What about memory? Anyone think I need to upgrade my memory? I have 8gig.

If you're able to boot, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.

How to Backup your HD and Reinstall Lion

Hello to all,
I'm a Student of Informatic Engineering studiying at UCAB in Venezuela.
I have a Macbook Pro 13" late 2011 and needed of windows and ubuntu because some projects at University needed to be developed in those OS. I did the Bootcamp to add Windows to my MacBook Pro, and did an extra partition to the Macintosh HD to install the Ubuntu. All Sucess and finished the semester. Now i dont need these OS no more because i won an Acer and now i have Windows and Ubuntu in that laptop so i want my Mac only with OSX. Besides now the OSX is startint to act funny, so i think its about the triple partition (and i dont like my apps in OSX closing for no reason, and the system is getting a bit slow).
So, my question is:
1.- How do i Backup my Macintosh HD so i dont lose all my installed apps and data.
2.- Can i use Time Machine on any External Hard Drive?
3.- How do i clear all my hd so its like brand new, and Reinstall Lion (because when i bought the Mac it didnt came with an OS CD)
Thanks for any help you may bring me..
I'm Sorry for any misspelled word, English is not my main Language.
MacBook Pro 13" (Late 2011)
Specs:
Processor: Intel Core i7 2.8Ghz
Ram: 16GB 1333 Mhz DDR3
HD: 750 GB (Macintosh HD: 550 GB, Bootcamp: 160GB, Ubuntu: 40GB)
Graphics: Intel HD 3000

1.- How do i Backup my Macintosh HD so i dont lose all my installed apps and data.
2.- Can i use Time Machine on any External Hard Drive?
3.- How do i clear all my hd so its like brand new, and Reinstall Lion (because when i bought the Mac it didnt came with an OS CD)
1. Use Time Machine - it's on your Mac.
2. Yes - if the external has enough space.
3. After you back up, use the steps described in this Macworld article to make a clean install of OS X. Basically you reboot while holding down the command and R keys and proceed from there.

A 2008 Mac won't have originally shipped with Lion. You need to install 10.6.8 on the computer, log into the Mac App Store with the Apple ID you used to purchase Mountain Lion, click on the Purchases tab, and download it.
