Mini won't boot up from internal hard drive

Greetings,
I can't get my Mac Mini to boot from it's internal hard drive. It just gets stuck at the grey apple screen wth the spinning gear, nonstop. Booting in safe mode produced the same behavior (still wouldn't boot). DiskWarrior fixed some directory problems and found some corrupted microsoft office files which I deleted but it still won't boot. It boots fine off an external USB drive.
I've tried disconnecting all peripherals except keyboard, mouse, and monitor, resetting NVRAM/PRAM, and reinstalling the OS over the existing one (but not a clean install).
Disk Utility and DiskWarrior both now say the boot drive is fine, but of course it still gets stuck at the grey boot screen.
Booting in verbose mode it shows the following errors and then hangs:
disk0s2: I/O error.

Other than a complete wipe and reinstall I don't know what else to try.

Hmmm,
qErr

Failing in /usr/libexec/configd makes me think some file like...
/usr/standalone/bootcaches.plist
/private/var/db/BootCache.playlist
Is possibly corrupt.

Mac Mini Won't Boot or Internet Restore - Hard Drive Boots on Macbook

Late 2012 Mac Mini. I cloned my 10.10.2 installation of Yosemite over from my Macbook pro 6,2 to a 1TB Samsung 840 SSD. It booted with no issues besides the keychain being lost and all passwords having to be re-entered.
After a week of going perfectly, it stops recognizing the USB keyboard after I unplugged it and plugged it back in. So I rebooted and get the dreaded stop sign after the boot failed. Oops. I enabled trim before I cloned, but forgot to check if it was working in the cloned drive (seems it was in the end). Since there was no recovery partition, I booted into Internet Recovery, but that hung using both WPA and WPA2 router logins. It obviously was syncing with router, but I got error -2002f in every configuration I tried. It also didn't seem to recognize an ethernet connection. Weird stuff.
I remembered I had an issue with a previous Mac Mini of the same model and the permissions after a clone. I repaired permissions and that was that. This is different because it wouldn't boot into Safe Mode. Resetting the PRAM did bring back an audible chime at least.
I pulled the SSD out of the Mac Mini and alt booted in from my Macbook 6,2. No issues (except the keychain thing again( and it loaded quickly. Nothing seemed to be wrong.
Then I put it back in the Mac Mini and tested it with known working RAM. Still the same thing. So now I am going to sleep on it and try to figure it out. It is unlikely to be a hardware failure as the Mac Mini was made in May 2014 and I bought factory refurbished. It seems to be an issue relating to the SSD as it boots other drives.
Any ideas?

Is this SSD an additional drive added to your Mac Mini or did you replace the HDD with it? If it's an additional drive and since it's a Samsung, depending where you purchased your drive doubler kit (iFixit or OWC) you can try swapping the drives in the bays. I know for a fact that Samsung SSDs do not work right with the iFixit drive doubler kit's SATA cable. But it does work correctly with the Apple supplied SATA cable. If it's the OWC SATA cable, I know for a fact those are much more reliable with Samsung, OWC, Intel, Crucial SSDs. Another thing, I would NOT enable TRIM (my opinion) using a 3rd party trim enabler if you're running Yosemite. There are issues with trim enablers and Yosemite. Just let the built-in Garbage Collection take care of things.
If it's not an additional drive that was added, does your Mac Mini boot and work fine with the stock drive that it came with? Even though it's a 2012 model, if you purchased it refurbished from Apple in May 2014, you're still under warranty (same 1yr as new Macs) and if it's having same or similar issues working with the stock drive, you can take it to a local Apple Store for warranty repair. You would need to have only the stock drive installed (no SSD) before you setup an appointment.

How to migrate from internal hard drive to SSD (Solid State Drive)?

I just bought 128GB SSD. I want to replace my internal hard drive with SSD on MacBook Pro. My internal drive has only Mac OS installed (no dual boot with Windows/Linux). Going forward I want to boot my Mac OS from SSD and use internal drive for backup purposes only. I read many forums regarding this here, but each one talks about different methods of doing it.
* Carbon Copy Cloner for the Mac side (free)
* Casper 6.0 for the Windows side (not free)
* SuperDuper
Can some one provide me with simple steps to migrate Mac OS along with my personal data from internal hard drive to SSD?

Because Windows is not involved, you don't need Casper or anything else Windows-related.
Use Disk Utility to repair permissions and repair the directory on your internal hard drive. Buy an external SATA hard drive enclosure* and mount your SSD in it. Connect it to the MBP and use Disk Utility to create a single GUID partition on it, formatting the partition Mac OS Extended. Use SuperDuper or Carbon Copy Cloner, it doesn't matter which, to make a bootable clone of the internal hard drive on the SSD in the external enclosure. Restart the computer holding down the Option key, and select the SSD to start up from; the purpose here is to verify that the SSD really is bootable. If that works OK, shut down, disconnect the external enclosure, and exchange the drives.
*I recommend a FireWire 800 enclosure, but they are much more expensive than USB-only enclosures, which will work OK — USB is just slow.

No boot sector on internal hard drive and No bootable devices.

Hello, I hope someone can help me.
I have a dell inspiron 1525. I recently replaced on of my memory 512mb modules with a 2gb memory module. At the same time I change the 120gb harddrive and upgraded it to a 320gb harddrive. After doing this when I start the computer I receive the message:
"No boot sector on internal harddrive".
"No bootable devices - - strike F1 to retry boot, F2 for setup utility, Press F5 to run onboard diagnostic".
I have tried to change boot sequence and tried to boot from the Windows Vista Home Basic 32BIT. Regretablly with no results. If there is anyone who can guide me and help me to solve this problem I would greatly appreciate it.
Thanking you in advance.

Whenever we get this error "No boot sector on internal hard drive", it means that our hard drive has no partition/ boot sector to boot/ start operating system (Windows).
The ultimate solution is to install Windows from beginning either by using CD/DVD or USB bootable flash drive. You need to have windows installation disc or bootable flash drive for that.

A205-S5000 won't boot. Says possible hard drive problem

Laptop won't boot and says possible hard drive problem. Need to recover
personal reports and data, so thinking of removing the drive and using an enclosure
so the data, if still good, can be extracted from the drive by another computer. Question
is, will I be able to create the restore cd's from the hard drive if the hard drive is not the
boot drive ie; attached to a 2nd computer via usb and enclosure.
If it's not possible, I can try to create cd's from a different model laptop (toshiba), same vista os but
what about the product key? I will try to reinstall the bad drive and try a reboot to recovery mode but
I doubt that is going to work or complete. Idea was to get a new drive and try to install recovery disks.

Satellite A205-S5000
Recovery discs must be from an identical model. If you can't burn them from that computer, best to order them
Order Toshiba Recovery Media
The restored Windows is pre-activated.

New hard drive on dell inspiron 1545 no boot sector on internal hard drive

Hi, need some assistance, bought a new HDD o 500Gb, to replace my old one o 320Gb. but can't reinstall win7 64 bit sp1, it gives me the next message "no boot sector on internal hard drive"

Mr. Osprey is right, windows installation is required to boot the computer. The error "No boot sector on internal hard drive" appears when you have a new hard disk or your old hard disk has not bootable partition.

Snow leopard installation disc won't boot. Can I reset computer to boot from internal hard drive at startup?

I recently installed snow leopard on my macbook (mid 2006). I used system preferences to set the snow leopard boot disc as the install disc, and now my computer won't boot. It stalls at the apple icon with the grey screen. Is there any way I can set my computer to reboot from my internal hard drive at startup without having access to system prefernces (a keyboard code or something)?

Thank you so much for responding. I actually just pushed the trackpad button at startup. It ejected the install disc and automatically booted from the internal. I am sure your method would have worked as well. Thanks again!

Won't Boot from Internal Hard Drive

I received the "Startup Disk is Full" message and neglected to do anything about it before my Mac stopped booting. To remedy this, I installed and booted from Snow Leopard (10.6) on an external hard drive, found what was eating my space on my internal hard drive (currently Mac OS 10.5.8) and freed up about 35 GB of space.
I then went to my System Preferences to change the default Startup Disk back to the internal drive. It's not booting past the gray screen.
Any ideas on how to fix this? Do I now need to update my internal hard drive to Snow Leopard? If so, will this erase anything on my internal drive?

Hmm.
Do you have your external drive connected?
Try booting with the ALT key held down. Is your internal drive an option here? Choose it, then give the computer 5~10 minutes to boot.
If that doesn't work, try holding the Shift key and starting up in Safe Mode, which will take 5~10 minutes.
Do you have your OS X install discs for 10.5?

Can't boot from internal hard drive.

I just replaced my internal hard drive and copied the back-up from the old drive onto the new one. The new drive appears to be properly formatted and to contain all the data I copied to it, but I am unable to boot from it. Any advice? Thanks!

Thanks, Courcoul. I went back and formatted the drive again, this time booting from the OSX installation CD. (Last time I booted from the back-up drive from which I was copying.) I don't know if it was booting from the CD and not the drive, or that I didn't format it properly the first time, but this did the trick. Working perfectly.

How to create External Hard Drive from Internal Hard Drive?

For my Mac, I want to get a 250GB external Firewire Hard Drive. I know I can purchase one as is. However, it seems that money can be saved by purchasing an internal hard drive and a hard drive enclosure. Is this correct?
If so, would the internal hard drive be an IDE?
Is there an enclosure that will make this IDE drive a Firewire/USB external drive?
Should the enclosure have a fan, on/off button?
Anything else to consider.
Thanks,
Herschel

Hi Hershel.
1) If you want to use the drive with both your PC and your Mac then you have two options. Either you format the drive in FAT32 (standard windows format) or you get hold of one of the utilities which allows you to read Mac HFS+ formatted disks on a PC (IMHO the better way to go). One disadvantage of using Fat 32 formatting for the drive is that you then won't actually be able to use it as an emergency "startup disk" for the Mac . The other problem is that Fat 32 can be problematic with large disks and files sometimes.
2) Your iMac has both USB2 ports and firewire 400 ports. There is no advantage really in getting an enclosure with Firewire 800 , because your iMac is limited to Firewire 400 anyway. The drive you buy to insert in the enclosure won't have any effect on this.
3) The reasons for getting a firewire capable enclosure for use with your Mac are that it is actually faster than USB2 (despite the higher rated speed of USB2) and because you can start up your Mac from an external FW drive, but not from an external USB2 drive. If you are formatting in Fat32 this won't be an issue because you won't be able to boot from it anyway.
4) The business about "parallel" and "serial" drives relates to the type of bridge in the enclosure that you buy, not to whether you want to connect it to a PC or a mac. Some enclosures are designed to work with "SATA" drives - ie Serial. Some are designed to work with "regular" IDE / ATA drives (ie parallel).
Just to make this clearer , think about this as involving two links in a chain. THe first link is from the drive to the enclosure. The enclosure needs to have the right sort of INTERNAL connection for the drive you buy - either SATA or regular ATA - regular ATA enclosures are more common than SATA one but large drives are now easier to find with SATA interfaces than IDE ATA. A few enclosures can accept either type of drive,but they tend to cost more.
The second link is the EXTERNAL one from the enclosure to your computer. In your situation it sounds as if you ideally need one which has both Firewire 400 and USB2 connections. (THere are also some cases which provide am external SATA connection for connection to the computer, but you wouldn't be able to use this with your iMac as it has no external SATA port).
Try a Google for the IceCube Pleiades and you should be able to come up with prices in a place somewhere near you. At present I'm not sure which country you are in.

How do I boot Leopard from external hard drive?

I'm currently staring off into space... my 3 month old MBP seems to have finished its painfully long boot and all that appears the Leopard background. The local Mac guru isn't available until Monday but did tell me I need to boot from my external hard drive. Um, how do I boot from external hard drive?
The cause of the problem: inserting flash drive powering up.
Tried safe boot. Only difference was iCal reminder popped up in space.
Mac guru told me do NOT use install disks!
Help!
AR

Apple support has told me that you cannot boot a MBP from an external drive when Leopard is installed on a MBP.
That is just plain wrong.
1) Hook up your external drive. Use FireWire for better performance.
2) Launch Disk Utility and highlight the actual drive icon at the left. Click on the Partition tab.
3) In the Partition section, click on the Options button. Click on the radio button for "GUID Partition Map". This is the option you must use in order for a drive to be bootable on an Intel based Mac. Click OK.
4) Set up your partitions however you want and click the Partition button at the lower right.
From here, you can either clone your internal drive to the external, or install Leopard on it from scratch.

Booting XP from External Hard Drive

I have this external hard drive:

Is it possible to run Windows XP from that USB2.0 Hard Drive without having an internal hard drive connected to the computer?
How would I enable booting from USB devices in the BIOS?
Thanks.
Fizz.

Q-1: I don't know.
Q-2: In BIOS setup, in "Advanced BIOS Features" select "Boot Sequence" then select "Boot Other Device". Page 3-8 of the manual.

Moving iTunes from internal hard drive to external hard drive

I would like to know if it is possible for me to move my iTunes library and all iTunes files from my internal hard drive to the external drive that I just purchased. My Laptop is running out of memory and I assume if I move it to the external drive it will free up space. Can anyone here help me?

If you have iTunes 7, then you can just drag the entire iTunes folder to your desired location. Then hold down the Shift key while launching iTunes. You'll be given a dialog box where you can select the iTunes library you want to use. Navigate to and select the iTunes folder in it's new location.
Forum Tip: Since you're new here, you've probably not discovered the Search feature available on every Discussions page, but next time, it might save you time (and everyone else from having to answer the same question multiple times) if you search a couple of ways for a topic, both in the relevant forums, in the User Tips Library and in the Apple Knowledge Base before you post a question.

Removed photos from internal hard drive (iPhoto), but it also removed from my external hard drive (iPhoto). HELP!!

I just bought a new external hard drive (Seagate) to move my numerous photos in iPhoto off my iMac. Set the EHD up to work on both Mac & PC. When I removed some of the photos in the iPhoto library on my internal drive it also removed them from the EHD (defeating the purpose of having the EHD).
After I have copied the photos from iPhoto to the EHD, how do I remove ONLY from the iPhoto internal hard drive (without losing them from both)???
Thanks in advance for your advice.

Did you use the File/Export menu function within iPhoto?
Did you look in the iPhoto Trash and your desktop Trash to see if the photos are still there? Hopefully they are in the Trash and you can retrieve them and do a proper export to your external hard disk.

Boot OS from external hard drive?

Hi, I'm currently planning on getting a Macbook Pro laptop. However, I don't like Mac's OS X and I was wondering if it's possible to install Vista and Linux onto the computer THEN move all of Mac's OS onto an external hard drive where I'm able to boot up if I choose to. You might suggest to just get a laptop with Vista already on it to save the trouble, but I'm doing this because the new Macbook Pros have the specification and I like [i.e. graphics card, processor, ram, price] and unlike customized laptops like Alienware, the new Macbook Pros are not as expensive and somewhat in my price range. So:
1. Is it possible move the Mac's OS to an external hard drive to boot up when I want?
2. Would this cause any problems if it's possible and I install Vista and Linux?
3. Can Geek Squad agents help me do such a thing?... can they work on Macs and with Linux? [I've never used the Geek Squad service except asking a couple of questions so I don't know your policies.]
4. If so, roughly how much would they charge? [I would do this by myself since I'm pretty computer savvy, but if it's a reasonable price I would rather go to the Geek Squad instead of risking messing up a brand new computer.]
Any other information would be great. Thanks for your time.

Hi joka!
You post an interesting question which puzzles
me. I just did some casual surveying of
Mac enthusiasts around me and learned that they are often loyal because of the
way Mac Book Pro is manufactured. However, all of them agreed that Mac OS X is
one of the reasons they own a Mac and that it would seem more practical to get
a PC in your scenario. I understand why some
customers want to tap into the coolness factor of a Mac Book Pro – yet may need
Vista or XP for business. This is simple enough to achieve using Boot Camp. What
you want to achieve may be possible, but not practical because of slower data
transfer rates to external hard drives. Perhaps
if you still want a Mac, then you would be better off leaving all three OS
choices on the ample Mac internal hard drive and use the external drive for
storage? Anyone else have suggestions?
