Flashing Question mark Folder and clicking - no start up.

Dear Mac Users,
I've already got some info on the above, but my 3.5year old G5 iMac wont get past the flashing question mark folder icon. It can't find the start-up drive. The think the hard drive is dead - if I start up from external HD it's OK and/or Tiger CD - but the mac's HD is nowhere to be seen on any disk utility.
Just bought Disk Warrior - that wont see the iMac HDrive either - so unless anyone has got a fix, it looks like the thing will be dumped or I get a new HD. Are these easy to buy and fit? It's a Rev A model, (the buzzy first edition). I haven't got all my files backed up, just the key ones, which are now on a new alum iMac. Or I could run it off an external drive (noisy, though).
I had been moving the G5 around a lot (switched off) before it went belly up - could this be a cause?
Maybe it'd been feeling left out, with the new 24in installed.
Hope someone can shed further light.
Rob
(PS - anyone want buy my Disk Warrior?)

Your drive is dead, you can look in [macsales.com] or [smalldog.com] for a new new one. The drive isn't too difficult to replace, you can do it yourself, and do get the largest one you can afford, just make sure it's a 3.5" SATA.
Keep your DiskWarrior, you never know when it'll come in handy.

Boots to flashing question mark folder and disc utility cannot locate internal hard drive

Bottling my MacBook Pro I end up with a flashing question mark folder. I reboot holding the option key to select discs and there were no options at all. I plug in an Ethernet cable and it shows a internet recovery option. I click and it downloaded a temporary recovery mode. From there I open disc utility but it doesn't find any internal hard drives. I reset the pram and I still get the flashing question mark folder. Thinking it was my internal hard drive that failed I bought and replaced the internal hd with a new one and repeated all the processes and still no internal hard drive was found. I'm stuck with the flashing question mark folder. Therefore I've concluded that it was my MacBook pros internal hard drive CABLE that had failed. Does anyone know of any other possible problems that is causing this for my MacBook Pro or know of any solutions? Or is replacing my internal hd cable the only solution? Please help!

It was the internal HD cable. I replaced it and now my MacBook Pro works

My macbook is getting the question mark folder and also my start up disks are gone

A few weeks back I turned on my macbook and discovered that it cannot boot up anymore. There was absolutely no precedent to this. I didn't drop it (I've dropped it many times in the past if that matters, and may have placed it down on my desk a little to aggressively the night before), and I had no problem using my computer right before going to bed. I just closed it went to sleep and the next morning my computer was malfunctioning. Whenever I turn it on the computer is stuck at a grey screen with a blinking picture of a folder with a question mark on it. I thought my computer was a lost cause and I bought a new one, but now I am in desperate need of recovering my lost files on my old computer which I still have.
So I go to the internet for help, with my goal being to just fix my old macbook or at least salvage the data, and read that the thing to do is press command+R when the computer boots up and fire up internet recovery, then go to disk utility and fix the drive/disc/whatever from there. So I press command+R at start up, and I get past the loading screen with the globe and go to a menu giving me the options of disk utility, time machine, reinstallation, and looking on mac forums for help. I click on disk utility and my mac os x disc does not appear to be on the left hand side. There is one disk under a disk that says Disk1 that says MAC OS X BASE SYSTEM or something to that effect on it, but if you click on its info it says that that particular disc has a total capacity of only 1.39 GB, so that can't be it, right? Also when I click on it it doesn't give me the option to verify or repair it. There's another disk at the very top of the left hand side that says 4.14 GB ST_M13FQ8L M... but it also has a low total capacity.
After I find no help in disk utility I decide to take a different route and see if I have any time machine back ups and it asks me to select the disk that contains the backup I want to restore, but the list that is shown is empty. I don't remember ever setting up a time machine back up so this doesn't surprise me.
So I move on to another solution- to try and reinstall MAC OS X Lion and it takes me to a window where it asks me to select the disc where I want to install MAC OS X Lion, but the the little white box under the message that is supposed to show a list or something of the available selections/discs is completely empty. So I have no start up discs?
Then I click shut down on the upper left hand corner of the screen to turn of my computer and another window appears asking me to select the system i want to use to start up my computer but that box is also completely empty.
I don't know what to do this at this point, and I don't know how to interpret the situation either, even after researching the issue on the internet. Does this mean that my harddrive/disc or whatever is completely gone/broken? And more importantly does this mean that all of my data is gone forever? Or is the system or computer itself broken or something like that, but my hard drive is intact? Now that I have a new computer all I really need is to somehow transfer the data from my broken computer to my new one, and don't really need to "fix" my computer- but if fixing it is the only means to see my data again that's what I want to do. And also can I fix this manually by myself, or does this require professionals. And if i do need to hire someone, how much will this typically cost? Thanks!
Some other facts: The macbook in question (the broken one) is an aluminum 13 inch macbook pro from I think 2012, maybe 2011, and used to run on Mavericks. I also used to have windows bootcamp on it but i rarely used it. The macbook has been having some problems for a while and recently started to slowly break down. The USB ports stopped working completely, all of its apps were slow and glitched a lot, the battery in it was nearly dead (it said REPLACE SOON where the battery symbol used to be on the upper right hand corner of the screen), but it still worked at a base level and I used it for work and stuff, up until this point of course.

A flashing question mark appears when you start your Mac

Flashing Question Mark Folder - Cannot Eject Disc - Problem Startup

My Macbook will not start up. I get a flashing question mark folder and will not startup.
Also, I have a dvd inside that will not eject.
Any suggestions?

You will need to reinstall OS X. Try this:
How to Perform an Archive and Install
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
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 Installer menu (Utilities menu for Tiger.) 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, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
If your drive cannot be repaired then you will have to reformat the drive and install OS X from scratch.
To eject the DVD press CTRL-E while booted from the installer disc or hold the mouse button down while the computer is booting from the installer disc.

Hard disk in mums macbook failed, bought a new one, formatted it first. Have tried starting it with every possible key and I either get flashing question mark folder or a cursor.

Hard disk in mums macbook failed, bought a new one, used sata adapter cable to format it for mac first. Connected it and have tried starting it with every possible key combination and I either get flashing question mark folder or a cursor. A disk is stuck in it so I can't boot from OSX, and yes I have tried every option of starting to try and eject disk but none work. HELP ME!

Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the
      left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
      your Utilities folder. At the prompt enter or paste the following:
        /usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
If you have a 2010 MBP or later, then you can use Internet Recovery. Start by rebooting the computer. At the chime press and hold down the COMMAND-OPTION-R keys until a Globe appears in the upper part of the screen. This process can take upwards of 15 minutes to get connected to the Apple network servers. You should eventually see the utility screen of the Recovery HD. You may now go about the process to install Mountain Lion:
Install Lion/Mountain Lion on a New HDD/SDD
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 Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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 Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

There is no installed OS or you have a dead hard drive. Start by booting from the original installer disc that came with the computer or an installer disc that has a later version than the original such as a Snow Leopard DVD. Then you can do this:
Reinstall OS X without erasing the drive
1. 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.
2. Reinstall Snow Leopard
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.

Flashing Question Mark Folder on Start-up

I recently starting having administration issues with my Mac Mini.
I went to update to OS 10.5.7 and when the administrator box came up asking for my password, my name was missing. After putting in the correct information, was unable to update, but received the message what my clue to password was.
Anyway, I performed a safe startup, changed the password and tried again. Same issue as before. So I started up from the Start Up Disk, and ran Disk Utilities and verified the disk and repaired any permission issues. When I started up my Mac Mini from the hard drive, I still did not have my administrator password working.
At this point, the start-up ping is gone.
I reset the Pram and had the same issue. So, I saved all important files to an external hard drive and tried to do a clean install. I was unable to do the clean install.
I removed the hard drive from my Mac Mini and installed it into a friends Mac Mini. I had complete control of my computer with no administrator password issues, the ping was there, and I could reload all saved items and still not have any issue no matter how I started up the computer. I then performed a complete erase and reinstall and still had no problems.
I reinstalled the hard drive into my Mac Mini, and I now have the Flashing Question Mark Folder with gray screen on start-up and no ping. Can't fire wire to start up, can't clone, can't start-up from disk, safe mode, etc..
Any ideas would be helpful. Most likely I will be going to the Apple Store and seeing what they can do.

generally, the flashing folder mark means it can not find the startup drive.
if you hear those kind of noises your hard drive is most likely dead. while this is almost certainly true you can try booting from the install DVD and see if the drive is visible in disk utility. if you can't insert the DVD try this. reboot and hold option at the chime. this should boot you into startup drive manager. there you should be able to insert the DVd and choose it as the startup drive. boot from the DVd and once past the language screen start disk utility from the Utilities menu at the top. see if it detects the internal drive. if it does, try repairing it. if it doesn't the drive is dead.

HT1379 A flashing question mark appears when I re/start my MacBook Air 2013. At first, I pressed Power & Option button and it recovered from Internet. Then, four options appeared but none of them are helpful. Could u please help me to solve it asap?

Hello,
A flashing question mark appears when I re/start my MacBook Air 2013. Then, I pressed POWER & OPTOIN buttons and internet options appeared for internet recovery. After internet recovery, the OS X utilities appears with four options (Restore from Time machine, Reinstall OS X, Get help online and Disk utility). But none of them seemed helpful. On the last option Disk utility, the icon created only with 33KB and other disk 1 Mac Os X Base system. On First Aid, the icon Repair disk is disabled. So I could not click on repair disk. Could you please suggest me how to solve this problem asap? Thank you so much for your help in advance!

You can try the following:
Install or Reinstall 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.

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: Select Reinstall Lion/Mountain Lion and click on the Install button.

Flashing question mark folder at start, broken CD drive, warranty Q's.

Hello! Thanks for reading.
Okay, so here's the background: I was just chilling around the house yesterday with my macbook, and it freezes, with no response from the touchpad or keyboard. I figure no problem, and just turn it off and on again. And then thats when I got the flashing question mark folder.
So I hopped on my family's PC to do some research, hoping to be able to fix it myself. Turns out the best way to fix it is to pop in the disk that came with the computer during start up... which I can't do because my disk drive is broken. I also tried other things, like pressing various keys (ctrl + option + p + r, or something like that)... and that didn't work.
The disk drive broke when I was at school, and as it was finals week, I had no time to get my computer to a genius bar. Then I moved quite a distance (see below), a process which has taken up most of my summer and made me quite busy to the point it has taken my macbook pretty much dying on me to get it to a genius bar. Gah.
So I guess I have a lot of questions now.
My computer is JUST a year old, by give or take a week or two.
I bought my computer from an authorized U.S. reseller in Japan while I was living there (I live in the US now, which I definitely wasn't expecting a year ago)... and no contact from apple came to buy apple care. Is it possible that because of the circumstance under which I bought my computer, that apple may still cover any repair or replacement fees under the warranty?
Also, I made an appointment at the local genius bar. Will that be free?
Also, does anybody have any other suggestions about how to get my computer up and running away from the **** that is the question mark folder?
Much thanks! I appreciate your time.

You made 2 big mistakes. 1) Apple may or may not contact you about AppleCare (sometimes I've gotten a postcard or email and other times I've not) but it is up to you to buy it before the 1 year mark. 2) whether it was convenient to get the computer repaired at the time or not, you should have contacted Apple to get the issue in the computer. If you didn't, Apple has no reason to believe it happened after the warranty ended.
You are going to foot the bill for the repairs

HT201250 Flashing question mark folder

When I turn on my mac book a grey screen appears with a flashing question mark folder.
If I hold down the option key when I turn it on I get place my wifi password in and click on an arrow for Internet recovery.
Once the Internet recovery completes which took about 3 minutes I am then given the option to select my language the taken to the Mac OS X Utilities. There are 4 options:
1. Restore from time machine back up
2.reinstall Mac OS X
3.get help online
4.disk utility
Mac book pro information
Intel core i5
Mac OS X 10.7.5
Hoping someone can help and lead me in the right direction to fixing this!!!
Thank you

First of all, do you have backup of all your data? If not you may want to stop any troubleshooting until you have got that covered for fear of making the situation worse.
Assuming you do have backup, from your first post, where you started in Recovery mode, did you run Disk Utility (option 4) to see if it could discover/fix any problems? If not, open Disk Utility, select Macintosh HD on the left and click on 'repair disk'. If anything gets changed/fixed/altered, click on repair disk again until you get a 'clean pass' and then restart as normal from the Apple menu.

Flashing question mark folder OS X 10.6.8. Issue is not the drive itself.

Received flashing question mark folder on a MBP5,5 running 10.6.8. Removed the drive and was able to boot on same machine with the drive plugged in as external USB. Any idea as to what the issue may be? It's not the drive itself. Bad connector? Going to update the drive to mountain lion this weekend to see if that resolves anything.

Actually, it is the drive in some way.

IMac with flashing Question-Mark Folder

I've read all of the help on the flashing Question-Mark Folder. Nothing has helped. In fact, Disk Utility only finds 'Disk 0' with the base OS X operating system. All of the disk utility buttons are grayed out and at the top on the left of is 'Media' (not disk drive - not formatted?). When I try to recover from the internet and re-install OSX Maverick, it can't find a disk to install on. Does anyone know what happened and can this be fixed?

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.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling 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: Select Reinstall Lion/Mountain Lion 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.

Persistent Flashing Question Mark Folder Icon, after Repair & Rebuild-THX!

Hello All,
Thank you in advance for any insights.
For the past week, one/two days after a force re-boot, my Quicksilver Mac (OSX 10.4.11 and OS 9 Classic) starts up with the dreaded flashing question mark folder.
The start up disk has always been on "Mac OS X, 10.4.11 on main stuff" ("main stuff" is the name of the hard drive.)
The first time, I ran DiskWarrior and rebuilt the hard drive, which is kind of new as it was replaced in April 2009. Then I ran OnyX and got a clean bill of health. The Mac was shut down at the end of the day as is my habit via turning off the power strip.
If it helps, here's part of the DiskWarrior report:
• 13 files had a directory entry with an incorrect text encoding value that was repaired.
• 340 files had a damaged extended attribute that was repaired.
• 3 folders had a directory entry with an incorrect custom icon flag that was repaired.
• Incorrect values in the Volume Information were repaired.
Disk Information:
Files: 370,719
Folders: 85,161
Free Space: 92.55 GB
Format: Mac OS Extended (Journaled)
Block Size: 4 K
Disk Sectors: 268,171,472
Media: WDC WD5000AAKB-00H8A0
The next day, the flashing question mark folder reappeared. This time I used the original system installer CD (labeled Power Mac G4 OS X Install). Disk Utility made its repairs. And this time, the computer was put to sleep instead.
In the morning, it woke up, the wireless optical mouse worked for a few seconds, the hard drive is humming along then all of a sudden the arrow (mouse) froze and none of the keys on the keyboard functioned.
After some research, I deleted the energy saver preference (powermanager.list?) and ran Disk Utility again. And again, I shut down b/c I wasn't going to use the Mac for a day or two.
This afternoon, the pesky icon reappeared at start up. At first Disk Utility didn't see the hard drive then I restarted and the hard drive was selectable though not mounted. It was repaired and verified yet once again. Btw, when I did hard drive test, the message says something to the effect that it appears to be working properly.
My question is, might anyone know what's wrong? I've been backing up after every use and I have a laptop. But I love working on the desktop and if this issue can be fixed, that would be perfect.
As an aside, I've read that I should do a clean install. Would doing a clean install mean I need to re-install OS 9 as well as all other all other software programs-Adobe Creative Suite, Quickbooks, Verizon DSL, printer drivers etc.?
One final question, can I continue to boot up from the CD, repair then restart or will I damage the computer? Once it restart, everything seems to work normally and well.
Many, many thanks for reading and any help would be greatly appreciated!
Have a wonderful weekend.
Sam

Disk damage can also affect the startup sequence, but I think what you have already done should have repaired any disk damage, or given you more information.
Once you have ruled out Disk damage, you get the flashing question mark when your Mac cannot find:
• the preferred operating System
• of the preferred version
• on the preferred startup drive.
All these items are stored in the parameter RAM, backed up by a 3.6 volt, non-recharging 1/2-AA size battery that lasts three years or so, unless you turn off all power at night.
If you cannot remember when you last changed that battery, now is a good time. Be sure to reset the PMU/PRAM after installing the new battery.

How do I fix the GRAY boot-up screen with FLASHING QUESTION-mark FOLDER?

When I turn on the MacBook Pro laptop, I opened up the Safari Browser and its when the problem started. It was stuck on an loading infinite loop. I decided to force quit the application and/or turn off the mac by the Menu options, It did not work. So I did a "Hard" Shut-down and restarted the Mac, the Boot up screen stood gray for like a minute until the Flashing ? Folder icon showed up!.
My sister's laptop's warranty is expired so I wonder how can I fix it without having to spend too much money on a simple troubleshooting tip.
How can I download/create a boot-up Disk/Flash Drive so I can reset it to factory settings?
I cannot access the laptop because It's kind-of software bricked if you ask me. Also, I do not know how to check the Mac OS version outside of the "About Mac" menu. I do have another Mac which is a desktop computer with a CD drive.
I would appreciate some expertise on this issue a.s.a.p. Thank you!

Ok, now I am stuck:
Why does my Mac boot its OS from the Flash Drive instead of the INTERNAL HARD DRIVE???a
If I start up my MacBook Pro, It will have the flashing question mark folder UNLESS i plug in the OS-Boot flash drive. When I at the desktop screen and work on a program, When I unplug the Flash drive, THE OS WILL CRASH AS IF I TOOK it's soul (OS x Lion) out of the body (MacBook Pro Laptop)
this is frustrating because when I did the INTERNET RECOVERY, When I install OS x Lion, the Flash Drive only show up as an option as opposed to the HDD.
I cannot format the hard-drive in DISK UTILITY because it's grayed out. This is just frustating. I never had problems with PC Windows OS recovery but this (Mac OS).

Flashing question mark folder on macbook pro startup. PLEASE HELP

I have a MacBook Pro which I think is a 2011 version. When I startup the computer it comes up with the flashing question mark folder. I can't start it up via disc as I do not have the disc that came with the mac :( .

Di you try restarting and booting whilst holding down the command and R keys? Or even the command, option and R keys (assuming that you've a 2011 model)?
Some 2011 models came with discs as they shipped with Snow Leopard. Those that shipped with Lion had no discs. If your machine originally shipped with Snow Leopard, you can call Apple, with the serial number of your MBP handy, and order a set of model-specific discs (cost is, I believe, around $25 with taxes and shipping).
Please 'call back' and let us know if you've tried booting either to your Recovery partition or to Internet Recovery.
