Booting system from an external drive; Folder with Question Mark

Hello all. I am trying to setup an external USB hard drive as a bootable device for my Tiger install. This is on a Core Duo Mac Mini. I have successfully partitioned it using GUID into two partitions; A small 5gb partition for the minimal OSX install, and the remainder for data. I installed OSX onto it via my included Tiger discs that came with the Mini, no problems. However, when I try to boot from it I get a Folder icon with a question mark in the center. I can boot the Mini normally and browse the external partition. It shows no problems. Disk Utility also shows no errors on the drive. What have I missed?
For any who are curious, my goal here is to use NetRestore to make a backup image of my main Mini hard disk. Then by booting to the external USB drive, I will be able to restore the backup image (stored on the data partition of the external drive as well) to the internal Mini hard disk.
Mac Mini Core Dio Mac OS X (10.4.7)

Just letting everyone know that I am still unresolved on this one. I have tried it all; Zero-overwrite erased the external drive before partitioning it, used Carbon Copy Cloner to clone the boot disk, you name it. Every situation leads to the same result; no ability to boot from the USB drive, It just acts like it can't read it. Are there "undocumented" problems booting from USB on Intel macs?

Mac doesn't boot from start volume - blinking folder with question mark

Hi,
my iMac with Snow Leopard 10.6.6 issn't booting anymore from the Hard Drive. It shows a blinking folder with a question mark. After starting, before the folder appears, I hear a two or three times "clack" sound with a following silent speed down of a fan.
So I started from the installation DVD. On the "Choose Startup Disk" Menu there appears only the DVD and network. In Terminal by using "df" i only see my external Hard Disk, the DVD, and some /private/var folders. By listing the "/Volumes" directory only the external disk and the DVD appear.
I tried to restore a Time Machine backup from the external disk. After choosing the backup in the dialog "Select for Destination" it says "Searching for disks" but it doesn't find any after waiting some minutes. It also shows "This disk does not have enough space to restore your system" but there issn't any disk selected.
For me it looks like the Hard Drive with my system is dead. Does anybody has another idea what I can try?

unfortunately I can't start the single user mode. It is always booting from the installation DVD. I tried mouse clicked at boot to eject it, but it doesn't work. Also I can't come to the Startup Volume menu by holding the option key. I always come to the installation menu. There I can't eject the disk from Disk Utility, because it is working on it. I also can't eject it using the eject key on the keyboard in the Startup Disk menu. From the Terminal I can't access my Hard Disk from /Volumes and therefore also can't access my user's home directory.

Wont Boot or Install New OS - Flashing Folder with Question Mark

I was trying to upgrade the OS. It downloaded all files. Asked for restart and then went into this mode of displaying flashing folder with "?". Tried to boot from original install CD by pressing down C key but again it gives flashing folder with "?". If I boot with D key even then it gives flashing folder with "?"
Should I try to replace the hard drive?
The CD I was trying to install from MAC OS X Install Disc 1 (10.4.8)
Thanks

Thanks for the reply.
It is an Intel processor. 2.16 Core 2 Duo.
I believe it originally came with Tiger pre-installed - it was purchased around early to mid 2007. However, it was then used by my son who went to a boarding school where they installed 10.5 I believe. And they "locked it down" with parental controls etc. Perhaps that is part of the issue.
I had logged into admin and was doing an OS Update (dont recall exact function). It downloaded bunch of stuff and then asked for reboot. On reboot it got stuck on the flashing folder.
The CD/DVD I am using is an Apple CD which says
For Mac Computers
Mac OS X Install Disc 1
Mac OS Version 10.4.8
Copyright 2007.
I assume these are the original CD/DVDs that came with MacBook Pro.
Thanks

After reformatting drive - folder with question mark appear

I am using an iMac 2010
I was planning to reformat it and install the OS Maverick from my drive but after formatting (which delete all the files from it's hard drive) after restarting a blinking question mark appears
I have a wireless keyboard and mouse and I am trying to boot it with a CD of OS X 10.6.4
nothing is happening when i press option c , command R ,etc
what should i do?

Hi,
- Try booting with the Option key and select the Install CD in view: Startup Manager: How to select a startup volume
- If the Option key does not respond with Starup Manager, try with a wired keyboard.
See how you go

Switched on my imac 24inch intel based and all I get on screen is a folder with question mark flashing,I had backup on external hard drive but when I try to reinstall it can not find my mac hard drive

Hi when I started my intel based imac this morning all I am getting is a folder with question mark in the middle flashing,I have external hard drive with backup,but when run disc utilities it does not show my mac hard drive.hope someone can help.(it's running mountain lion, well it was)

Try starting up your Mac while holding down the Option key. That should prompt the Startup Manager window where you can select the startup disk then click Restart.
The question mark folder indicates your Mac cannot find a system folder to boot from.
A flashing question mark appears when you start your Mac

Ssd can't boot from mainbay folder with question mark

Hello I've searched for my problem but can't find anything same so I'm gona ask.
first of all I'm sorry for my English.
I'm using MacBook pro mid 2012 with samsung 840 evo ssd 500gb.
today it was working perfect it felt asleep and after wake up it restarted and flashing folder with question mark appeared on screen.
I Know it's some kind of hdd problem. So I've took it out and put in external box to connect to my friends MacBook to see if it's working and does all information is still in it. It was working perfectly. after that I connected it via usb and boot it by holding opt key and it startups normal. To check that it isint sata cable I have puted empty hdd in main bay and booted from ssd connected by usb and both drives show up in disk utility.
So hdd working perfect. Sata cable is good and can read drive.
Macbook boots from ssd connected by usb without any problems.
The only problem is that I can't boot my MacBook from ssd in mainbay it shows flashing folder with question mark.
Maybe anyone had had that issue before.?
How can I solve this problem.?
again sorry for my English. And thank you for all your answers.

Do not apologize for your English. I assure you your English is better than what my facility with your language may be.
I have seen a couple of posts similar to yours where the SSD will not boot internally but a conventional HDD will. The resolution in one case was a new SATA cable even though the tests suggested otherwise.
I would take the MBP to an apple store and have them check it thoroughly and see if they can pinpoint to the cable as the problem. Obviously this just a guess on my part.
A call to Samsung technical support may also be a good idea.
Ciao.

Folder with question mark + wont boot from disk

Hi
I am trying to reinstall a powermac g5 from the disk, using a old hard drive that works.. (formatted in NTFS) (hoping that when selected to boot from disk, mac will then erase and reformat it)this image is presented when i hold down the option key and the disk ejects this other image is presented when i hold down C (folder with question mark blinking) and the disk ejects... also presented if i boot normally.... Could some help be offered please??????
Powermac G5
Thank you in advance

Yes, you must Format it HFS+ first...
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
How to format your disks...

When booting up get flashing apple folder with question mark and no sign, why?

When booting up get flashing apple folder with question mark and no sign, why? Computer will not open up. I have tried resetting the Pram. I can access the hard drive from another computer holding down the t key when starting up the Macbook Pro. What to do next?

The cable connecting the HDD to the logic board may be faulty. If the internal HDD can boot the MBP when in an external enclosure, that will confirm this issue. If not, the HDD may need to be replaced.

Blinking folder with question mark! Recovery mode not recognising hard drive!

So today on my MacBook Pro 13" mid 2010, for some reason a CD that I inserted inside the DVD/CD drive didn't come out, and was stuck inside. So I looked up on how to force eject it out, and I saw someone wrote that you can force eject the CD by putting a paper clip inside the hole next to the CD/DVD drive. I did this, and it did not work. After I turned on my MacBook Pro and on the startup I found the blinking folder with question mark! I went through Internet recovery mode, and I found out that it did not recognise my hard drive!
-Do I have to replace my hard drive?
Please help! I'm fairly new with computers :(

That was for very old Mac's and PC's, it's been a long time since any modern Mac had that ability.
CD that I inserted inside the DVD/CD drive didn't come out, and was stuck inside.
Press and hold the power button down to force a hardware shutdown.
Hold the trackbutton down and the option/alt key at the same time, now boot the machine.
The disk should spit out and you should eventually see a row of icons appear on the screen, this is Startup Manager and you can pres the eject key here also to get the cd to spit out.
If you see MacintoshHD (or your OS X boot volume) click it and the arrow underneath and when you get into OS X, head to System Preferences > Startup Disk and set it again. Your problem should be resolved at this point.
If you don't see your OS X boot volume and it shows RecoveryHD only, or holding the option/alt goes to Internet Recovery, then your boot drive is dead or there is some sort of other issue/power /Mac related.
Try a #1 SMC Reset and a #2 PRAM reset and see if that fixes things.
..Step by Step to fix your Mac
If not, I then suspect because you couldn't eject the cd that something electrical bad happened to the Superdrive and as a result it also effected the power or something going to the boot hard drive.
The hard drive might still work just fine if it's removed from the machine and a SATA to USB adpater to another Mac.
My advice is to take the machine to Apple for a free hardware evaluation, then decide what you want to do from there.
My computer is not working, is my personal data lost?

Boot up shows folder with question mark...

So my imac from 2006 (i think...20 inch plastic intel) booted up today to the blinking folder with a question mark on it. I rebooted into the osx disc to set the hdd as the startup disk, but it didn't show up in the list. Then I tried to see if I needed to repair the hdd using disk utility but the hdd wasn't showing up. So, do I have to replace the hdd? Not looking forward to it if I do.

Hi,
I have had similar issues, you will have to restart it and press and hold the eject disk on the keyboard right away and it will force it out.
Also to answer you question on way you are not seeing the Hard Drive and way you have the folder with question mark on the start up: is because your Hard Drive is dead.
You will need to buy another Hard Drive install it and then fresh install the OS X.
I have seen this issue too many times and every time is resulting with bad Hard Disk Drive...
Look at the bright side, Hard Drives are cheep now and you have iFix it to assist you on step by step installation. (this is unless you have Apple Care).

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

Hard drive crash? Folder with question mark

Hi everyone! I had problems with my macbook pro (early 2013). Last week, it slowed down suddenly and the laptop heats up during sleep. Then the hard drive recently crashed, at least I thought it crashed after it showed the folder with question mark during startup and did not show my old hard disk drive. Now I bought a 1TB WD mainstream hard drive disk, unfortunately it does not detect it in the internet recovery (disk utility). Now my question is, Do I have to do something with the hard drive first for my laptop to detect it? Like formatting it? The box said that it is compatible with mac OSx Lion, but my internet recovery lets me install Mountain Lion only. Is that the problem? or is the problem internal like the cable that connects the hard drive to the logic board?

That depends on the type of drive you have. If it is a standard external drive (in an enclosure) you can connect the drive with a USB cable.
If it is a bare drive like this:
You will have to put it an enclosure and get a usb cable. External drive enclosure are < $10. They come in two sizes, 2.5" and 3.5". Buy one that's correct for your drive. http://www.amazon.ca/MOGOI-Enclosure-External--Silver-Accessory/dp/B00HC107R6/re f=sr_1_5?ie=UTF8&qid=1404755872&sr=8-5&keywords=disk+enclosure

Folder with Question Mark on Boot

I can't get my mac to boot. Instead I get the gray screen and a folder with question mark icon. I'm guessing the HD is dead? Any chance for recovery? If not how much does a new one cost? The one year warranty just expired!
Please help!
Thanks,
Brian

So, what is it? The thing froze today and wont reboot - just a gray screen with NOTHING. Then after about 10 min. the flashing question mark folder appears.
So, I popped in the install DVD that came with the computer, get the little gray Apple logo and it boots from the DVD.
Launch Disc Utility. The HD appears on the left. Click on it - all of the "Verify" and "Repair" buttons remain grayed out. So what the hxll do I do?
I cant boot into single-user mode or any other mode for that matter.
This is a Macbook pro, dual-core Intel, less than a year old.

Installed new hard drive in imac and i get folder with question mark, put in OS install disk and it does nothing? All I have is wireless key board and mouse, is this a factor?

Other than put disc in you don't give much info about what you've done. With the install disc inserted restart your Mac while holding the C key, that should start it up from the install disc. Should also work fine with a wireless Apple keyboard.

Not solved with Blinking Folder with Question Mark after Erasing Hard Drive

Before asking, I found someone had asked exact the same question, but that was actually an unsolved thread.

in response to Niel
Thanks for the reply, held command+R again and it is trying to pick up WiFi, but it's not picking up my network and won't accept the password even when I try to put it in manually. Any thoughts on that?
Me too had tried the command+R and failed to manually connect to my network. Can anyone help?

Well, it was solved. I shifted to other place and tried other WIFis. One of the WiFi had the 2002f problem and another was fine, so the reinstall worked smoothly eventually.
On the apple support page it says that Supported network configurations and protocols includs both WPA/WPA2, not matter what they are, but it might not be true.
