Tried doing a clean install of lion and now have a folder with question mark appearing when mac boots

I purchased a 2011 mac mini I was having some issues and as I had already bought lion for one of my other macs and put it on a usb key I formatted the mac mini's hdd and put the usb key in to one of the Mini's usb ports and booted the mini up and held down c when the white scren appeard it stayed white for a few secnds and then a folder with a question mark started flashing no option to select my connected usb key I tried several more re boots and each time got the exact same result.
What on earth has apple done so now I can't even access attached drives during booting.
Any ideas how I can sort this out?

Maybe it is not "what has Apple done" You may have jumped the gun a little formatting your system so quickly without ensuring you can actually boot via an alternate method.
The mini has a recovery partition, and instructions how to reinstall the OS from that.
USB drive. Sounds to me like you don't have a proper OSX Bootable USB drive?
Also, the new way Apple allows reinstallation is over the internet too.

Imac froze and on re load folder with question mark appeared. Now will not start up to home screen.

The other night my Imac froze during updates. I found it in the morning with the screen and mouse frozen and only the loading icon spinning. I re stared the computer from the power button.
Upon re loading the apple logo did not appear and was replaced by a folder with a question mark in the middle. I looked this up online and found the best option was to use disk utility to check and repair the hard drive. This showed an error with HFS. Used disk utility to fix the hard drive so thast no error appear. I re stared the computer but all it loaded was the folder with the question mark again, so I decided to erase the hard drive of any information (I back up quite regulary, but left it as last resort due to inconvenience), when installing again it seems to go so far before telling me it cannot install and I need to re start. I have erased the dsk again and completed disk clean too before trying again and getting the same results.
I am currenlty stuck at this point and need help, which would be appreciated.
My Imac is an early 2008 Aluminimum model and installtion disk is 10.3

The folder with ? mark mean one of 2 things.
1) The OS is so corrupted that the hardware can't find it as a valid way to boot the system.
2) Your hard drive has failed.
You can try booting from the Recovery HD partition, Commadn + r keys at startup if you are running Lion Mt Lion or Mavericks.
Or boot the system from the original System reinstall DVD that came with your Mac or an upgrade OS X install DVd you may have purchased.
With either use Disk Utility to see if the hard drive is seen and if it can be erased or repartitioned and then restore from a Time Macine baclup or reinstall OS X.

I upgraded to mavericks yesterday and now i have the folder with question mark on start up

I've tried booting up pressing the option key and i get to the startup utility section but it won't let me erase, re-install or anything

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by one or more of these:
Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
Boot drive's directory has been corrupted - Repair with Disk Utility.
Critical system files are damaged or deleted - Reinstall OS X.
The disk drive is physically non-functional - Replace the hard drive.

Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.

If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Start the computer and only show a folder with question mark

Hi,
I need help please.
A few day ago I startup up my iMac and only a folder with a question mark was shown in the screen.
I boot from the Lion DVD, run disk utility but the only drive I get was the DVD and disk1/Mac OS X Base System.
I turned off the computer and next morning I turned on agian and this time with no problems, I use it for a few days with no problems but yesterday it happens again...
I do run disk utility again onlu turn it off, and this morning I tried to turn it on again, but the same foder appears...I run disk utility (get the DVD and disk1) and turn it off for a few hours.
Now I'm praying that when I'm back from work I could turn it on with no problems.
What I should do ? Is there any 3rd party tools that I can try do use to solve this issue ?
Many thanks!
PS: when the iMac started up with no problems I run disk utility and made a repair disk to the mac HD...

There are no Apple supplied Lion boot DVD's , you use command r to boot into Recovery HD partition, if that doesn't work good chance the drive is dead, it likely will have to pulled to test any data recovery efforts made.

Hold Shift key upon boot to fix the drive, reboot holding option and select OS X to boot and head to System Prefs, change the startup drive to OS X.
If you can't do this, your looking at data recovery efforts or repalcing the drive, total erase & restore.

The option key, set startup disk in system prefs should resove the issue.

MacBook Pro flashes file folder with question mark and startup manager will not run

My son's MacBook Pro won't boot (gets the flashing file folder with question mark). When I try to open startup manager (holding "option" key during boot does not do it). Other posts suggest inserting the install disk, but I am pretty sure that for Lion, there was no disk, it was just off the website through the App Store. Any further suggestions?

How to Create a Bootable Flash Drive to do a clean install of Lion. I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?

The system I'm have is a Mac-mini that had SL on it and no SuperDrive. I have also call Apple Support and they have really have not been to much help over 1st did my up grade to Lion and Installed the Lion Server.... it lost my SSL that I paid for and kill almost on of my server setting, plus kill all my web servers (using apache vhosts), and not to say the LDAP will even let remote users login to your laptops.
PS: There is no way that I'm going to buy a Install USB from Apple... They have over billed me over $300.00 because the Apps Store still has bugs (Glad I did not write that App/Service)
If there is anyone that can give in the information to create a USB install stick, I would be very thinkful.

Here you are bro, courtesy of "softpedia.com"....brilliant site!!!
If you ever had problems with your Mac OS X installation you know that the first thing you should do is to check the startup volume using Disk Utility.
After the check has ended and, if the errors exceed a certain level of seriousness, the Disk Utility application will require you to restart your Mac and use its Mac OS X Install disc counterpart.
Other users may have to reinstall OS X altogether, but will find, or already know, that their SuperDrive (a CD/DVD reader and write combo drive) is not functioning properly and it will not be able to read the Install disc.
Although this might happen to Mac OS X Leopard users due to faultyhardware, the vast majority of problematic SuperDrives will be encountered inside Snow Leopard running Macs.
This is due to the updated SuperDrive firmware included in either the Install disc or the software updates one has to install to reach the latest version of OS X, namely 10.6.6.
This can be fixed by flashing the SuperDrive’s stock firmware using free command line tools that one can find for free online (I will write about this process also, but at a later time because this article only focuses on allowing you to create your own alternative USB boot disc).
If you are reading this last bit of information with skepticism, than you should know that it happened to me too. Despite all my tries to make it work properly, the SuperDrive kept on munching any inserted DVDs and just popped them out in about twenty seconds.
The workaround to this issue was to create my own Leopard bootable USB memory stick. I am not suggesting a Snow Leopard bootable stick mainly because there are lots of users that have decided to buy the cheaper, Upgrade version, which I have not tested and, therefore, I’m not sure if it will work properly once written to a USB disk.
And now, here are the exact steps you should follow in order to obtain a fully bootable Leopard (or Lion) Install disc.
Step 1 (If you already have the Leopard install disc DMG file you can skip to Step 2)
Launch Disk Utility (you can find it inside /Applications/Utilities). Here select the Leopard Install disc in the list of drives on the left and click on the New Image menu entry at the top of the window. A save message will appear where you will have to select the Desktop as a destination.
Step 2
After Disk Utility has finished creating the Leopard DMG, insert your USB stick and erase all data and reformat the disk. To do this select the USB in the list of drives on the left and, after clicking on the Erase tab on the right side of the window, choose the Mac OS Extended (Journaled) format and click the Erase button beneath.
Step 3
After the USB has been reformatted, download the SuperDuper app from HERE and launch it. Once SuperDuper starts, you will only have to select the DMG in the Copy drop-down menu, your USB memory stick on the right and hit the “Copy Now” button.
One can also use Disk Utility for this task but creating a bootable USB stick failed 2 out 4 times when copying the DMG to the stick (with the exact same settings each time). Creating the bootable stick using SuperDuper proved to be the perfect way to do it because it worked each of the 4 times I tested it.
The steps above can also be used to create a bootable Mac OS X Lion USB by using the InstallESD.dmg image you can find inside the Lion installer (named “Install Mac OS X Lion.app”) downloaded from the Mac App Store in the /Applications folder.
To locate the InstallESD.dmg right click the Lion installer, select the “Show Package Contents” entry, go inside the “Contents” folder, and from there into the “SharedSupport” folder. Inside this folder you can find the InstallESD.dmg you can use to create your own bootable Mac OS X Lion USB stick. To do so, go to the third step described above and use the InstallESD.dmg as the DMG to be copied to your USB disc.
That’s it! Once the process ends you will have a fully bootable Leopard (or Lion) USB disk that you can use as an alternative to the Apple’s DVD Install disc that comes bundled with all Macs.
To use your newly created bootable disk you will have to restart the Mac, press and hold the OPTION key until the StartupManager appears. Here, select the Mac OS X Install disk using your keyboard arrows and press return to start from the selected drive.

Clean install of Lion and Time Machine

I have done a clean install of Lion and re-installed all software.
Now I would like to continue backing up this new, clean computer to the same Time Machine I was using before the clean install, preserving previous backups.
Is there any way to do this? I don't want to loose all of the data backed up...will choosing the old Time Machine disk overwrite everyting?
I don't want to try anything until I'm sure.
Thanks,
Margot

How are you planning to put your data back? If you use Setup Assistant or Migration Assistant, that should leave a "trail" for the next Time Machine backup to "associate" your "new" (erased) disk with the old backups.
If it doesn't, or if you use some other method to put your stuff back, you should be able to tell Time Machine to do it, per #B6 in Time Machine - Troubleshooting.

Clean install of Lion and proper Time Capsule procedure. Advice Please.

Good day all,
I have performed a clean install of Lion. I have previously been using a 1TB Time Capsule to backup my Snow Leopard disk. I did not use the Time Capsule to restore my files to Lion, instead I restored individual files from a backup of my Home folder on a seperate exteral hard drive. I have not yet enabled Time Machine in Lion. Is it advisable to erase the Snow Leopard backups using Airport Utility before enabling Time Machine? If I enable Time Machine without erasing the Time Capsule will it ask me if I want to erase or will it simply begin another set of back up data leaving the previous backups intact?
Thank you!

If you had used Setup Assistant or Migration Assistant to put your data back, Time Machine would do an "incremental" backup, of what's new or changed.
Since you didn't, TM doesn't realize the erased disk has most of the same stuff as before, and will treat your Mac's internal HD as a different one, and will do a new, full backup of it. You cannot prevent that. (If your backups were on an external HD, you could make it "associate" the backups with the "new" disk, but that doesn't work on network backups for some reason.)
So your best bet is probably to erase the TC's internal HD.
If it's quite large, however, you may not have to. If it's at least 2.2 times the size of what's on your internal HD, there will be room for a new backup.

I installed Lion and now have 2 system preferences(1 original and 1 alias). How to fix?

I installed Lion and now have 2 system preferences(1 original and 1 alias). I'm trying to clean up Launchpad and I have 2 system preferences and 2 iTunes apps. How can I merge or remove the unecessary files?

No. It's perfectly safe. An alias is just a pointer to the actual file, not the file itself.
BTW, the icons in the Dock are also just aliases, so it's safe to remove those as well, and just keep the ones you use often.
