How to boot from a repairing disk error? Windows 8.1

Hello,
I installed the iCloud yesterday for my iPhone 5s, and then a box popped up saying to restart and so I clicked OK as you do as i needed
to restart my PC anyway. So it restarted and went into Automatic Repair and now every time i start my computer it goes into this and then goes to a black screen, i need my computer for school and exams so need this sorted pretty quickly. i have read that it
is a common problem, but i can't seem to get F8 up the only think i can do is go into my motherboard settings and from there i can boot it form my SSD where the boot file is but this just tries to load it and goes to Automatic Repair. i can't get Microsoft
to help me as i need product identification number which can only be found when you have booted up the computer. Idiots !!!! Please can some one find me a step-by-step guide as I need this sorted quickly as i am in the middle of my exams. Thank you. Zach.

Hi,
Apologize for the late reply.
Do we have a Windows repair disk available? If yes, we may consider to take a system restore from there. We could contact the manufacturer to get a repair disk.
a) After you boot your computer using Windows DVD or System Repair Disc, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.
b) Select the correct time and Keyboard type.
c) Click Repair your computer in the lower left corner.
d) Select Troubleshoot from Choose an option screen.
e) Click Advanced options in Troubleshoot screen.
f) Select System Restore.
======
Or take a try to do a selective boot up with bios:
get cmd to open and check
bootrec /fixMBR
bootrec /Fixboot
bootrec /rebuildBCD
and also
chkdsk /r c:
chkdsk /r d:
chkdsk /r e:
chkdsk /r f:
Hope this may help
Best regards

How to boot from Panther install disk?

Hi,
May be a stupid question but I want to boot to my Panther install disk1 to repair my hard disk. I start the computer with the cd in the drive but it never boots from the cd. How do I do it?
Thanks,
Dave

Dave,
Insert the Panther Install disc, then restart the computer while holding the C key.

Solaris x86: How to boot from Veritas mirror disk?

Hello team,
We are using trailware Veritas Storage Foundation (VxVM) on Solaris 10 x86 system and need help in booting from alternative boot disk(Mirror disk).
Steps did :
1. Mirrored the root disk group using veritas volume manager command *"vxrootmir"*
2. Updated the bootpath with mirror disk path in /boot/solaris/bootenv.rc
Updated the EEPROM information:
# bootadm update-archive -R /a
3. Edited the grub configuration file, /boot/grub/menu.lst
Created the following entry similar to primary disk entry to allow the root disk mirror to be booted
title Oracle Solaris 10 8/11 s10x_u10wos_17b X86 <VxVM: Alternate Boot Disk>
findroot (rootfs0,0,a)
kernel /platform/i86pc/multiboot
module /platform/i86pc/boot_archive
4. reboot -- -r
At the time of boot, selected the newly added entry from the grub list and got the following error,
*"Reboot and select proper boot device or insert boot media in selected device and press a key".*
I am unable to move further from here, is this because of the veritas trial version we are using ?
Please help in resolving this issue and also explain the step by step process of booting from alternative boot disk on a x86 machine.
Let me know if you find anything inappropriate. Looking forward for your replies.
Thanks in advance.

Hi--
I have not seen this message before but a quick google search says that is pretty common and is related to the system
trying to boot from a different device (not the one you intended). Can you check your BIOS settings and possibly remove
devices from the boot order setting... Otherwise, I would suggest running installgrub on the disk that you are trying to boot
from.
I'm curious why you are trying Veritas. Is there a Veritas feature that you need? You might consider trying ZFS if you haven't
already. Its very simple to set up and use.
Thanks, Cindy

How to Boot from Leopard Upgrade disk??

I bought a Leopard upgrade disk last year for my iMac. Today I am having computer troubles. But there seems to be no diagnostic programs on the Leopard upgrade disk, nor does it seem to be a bootable disk. What should I do next?
The problem with the computer is, everywhere I click I get the rainbow colored spinny wheel. When I want to open an app, I get the spinny wheel. When I want to scroll in a window, I get the spinny wheel. It may take several minutes before the spinny wheel goes away, and the command carries out. Illustrator flat out refuses to launch, as well.

That's different. It's not an upgrade disk. It should be bootable. Insert the disk in your Mac and reboot while holding down the 'c' key. What OS are you running? What model iMac? Give some some info please. It will not have hardware diagnostics on it. It will have Disk Utility so you can run Repair Disk.

How to boot from Lion without disk

Iv'e done this before but seem to have problems remembering which keys to holddown during restart to get to disk utilities Comand R?

Cmd-R doesn't always work. If not, hold the Option key while starting. That will show the Startup Manager, where you can select from all available startup sources, including the Recovery HD:

Should I boot from external hard disk and how do I achieve this?

I'm in a downward spiral and need advice about if booting off of an external hard disc is the right thing to do and how to go about it. How I got into this mess I'll write below. My immediate problem is that I want to be able to install a copy of osx 10.5 from the original disks that came with my computer onto a usb hard drive. Then I want to boot from that drive and install software such as disk warrior on the same external hard drive in order to repair and recover the files on my internal hard disk. Not sure if this is easy to do with the install disk that came boxed with my macbook. So is what I want to do feasible and how do I do it? Thanks.
How did I get into this mess?
For those with time to read more. A downward spiral (and my macbook was working fine)::
I have been backing up my work documents onto a 20 GB pendrive waiting to get the money to buy an nas to work with time machine for the two macbooks we have at home as a place to backup photos and video. I bought a network drive but it wouldn't work with my macbook; my time machine backup freezing at 3 gb, but works fine with wife's macbook pro.
I tried to do TM backup on a usb hard disk and got the same problem. Support forums indicated that hard disk problems could confuse TM, so although I was experiencing problem free computing I ran disk utility from internal osx. This indicated an <invalid node structure - file system verify or repair failed> at the checking catalog file stage. So I followed instructions to run disk utility and repair from the installation disk. When I ran disk utility from installation disk I get exactly the same <invalid node structure - file system verify or repair failed>. It gets worse.
After failing with install disk utility, I could not then boot from my hard disk (I had had trouble free computing up to my attempts to use TM) or eject the disk. At first attempt I had no option but to boot from dvd again as hd not offered as an option. Second attempt hd option available but fails. By reading advice given to others I managed to eject the dvd and have tried:
safe boot - it won't
boot in verbose mode and single user (indicates I have disk0s2:I/O error) and won't boot
try to use disk utility from install disk to create disk image on external hd, it won't (cites i/o error)
If I can boot from an external I will try to repair with Disk Warrior as forums indicate that this software has been able to solve <invalid node structure> issues (but am open to recommendations of other products). I also hope that I may be able to try again to burn a disk image sucessfully if this repair works. I'm still trying to save my photos and videos that aren't backed up.
I plan to try an archive and install installation but first I want to try a repair with disk warrior as I fear that archive and install won't work and I'll end up having to erase and repair my hard disk.
I feel like some perverse god is punishing me for trying to do the right thing and back up my hard disk.
Macbook 5.1 late 2008
Intel Core 2 Duo
OSX Leopard 10.5.8
85 GB of a 150GB hard disk needs backing up (saving)

I am not sure about this, but my memory is that if you try to partition the drive (in OS 10.5.8) it will erase the data.
But you can try. Go through the Add a partition steps, but watch for any warnings. If my memory is correct there will be a message to the effect that everything will be erased. If you see that, do not proceed. This page has info about how to do it, if it can be done: http://www.macworld.com/article/1164643/live_partition.html
With respect to DW on an external, I do that. I have a 80 GB external - I call it Emergency - with an OS, DW and TechTool Pro on it. (Since I have is a recovery partition built in with all new OS, Emergency would be of use only if I need to run DW or TTP.) I have never yet had to use it, but it's there. It is not usually connected - I just did that for this screen shot.

Help please: how to boot from clone/external hard drive because "disk cannot be partitioned because some files cannot be moved"?

MBP Retina 15" MID 2014 2.5Ghz
OS X Yosemite 10.10
I have a external HDD and want to erase and restore my laptop so I can install windows via Bootcamp Assistant but I don't know how to boot from a clone to fix the issue and am not sure if when I erase and restore I will still have Yosemite 10.10? I have no way to reinstall the OS if I lose it. An average user friendly guide would be greatly appreciated please

I do not think you have to erase your MacBook's disk in order to install Windows. First of all you can try a few things before formatting the disk.
The first thing you should do is to check that your MacBook Pro's drive is OK with Disk Utility (in /Applications/Utilities). After opening it, choose "Macintosh HD" in the sidebar and press "Verify Disk". If it gives you any error, you will have to boot your Mac in OS X Recovery (press Command and R keys while your Mac is starting up) to repair Macintosh HD (the steps are the same but pressing "Repair Disk" instead of "Verify Disk").
After you have repaired the drive, boot up in OS X and try partitioning the drive again with Boot Camp Assistant. If it does not work, you will have to format the drive and reinstall OS X, but I will give you these steps only if this does not work.

How do i run a Repair Disk from ARD

how do i run a Repair Disk from ARD

have you considered a netboot image and or a safeboot?
With a netboot image you could try repairing the drive remotely. (the down side is this requires a mac os x server to do)
A SafeBoot can be remotely triggered, and it include automatic disk check and repair. (the downside is depending on how the computer is connected to the network, it may not re-connect to the network when safeboot complete and boots into 'safe mode'. ) I find if the computer is connected to the network by a built-in ethernet adapter, I can usually still access the computer in safe mode
Before running a disk repair or permissions repair, it's a good idea to make sure the computer is backed up.
Also, in the case that a NetBoot, Disk Repair, or SafeBoot fails, you would probable want to be able to physically walk over to the computer.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck explains that SafeBoot includes Automatic Verify and Repair of Disk.
Mac OS X: Starting up in Safe Mode explains how to use the terminal to configure a computer to SafeBoot into SafeMode. It also explains how to turn off SafeBoot after booting into SafeMode.

2) How to SMI Label/Format a disk while OS Installation in Solaris 11.1?
As we know that ZFS is the default filesystem in Solaris 11.
We have seen in the Oracle documentation that for rpool below are recommended:
- A disk that is intended for a ZFS root pool must be created with an SMI label, not an EFI label.
- Create root pools with slices by using the s* identifier.
- ZFS applies an EFI label when you create a storage pool with whole disks.
- In general, you should create a disk slice with the bulk of disk space in slice 0.
I have seen the solution that using format -e, we change the labelling but all the data will be lost, whats the way to apply a SMI Label/Format on a rpool disks while OS Installation itself.
Please provide me the steps to SMI Label a disk while installaing Solaris 11.1 OS.

Oracle recommends below things on rpool: (thats reason wanted to apply SMI Label)

How to boot from rescue disk

Hi,
I am running Macbook Pro, snow leopard 10.6.8
My resuce disk is based on 10.6.4
I tried to boot from rescue disk to repair the main disk.
I failed to boot from the rescue disk as my rescue disk (from CD) is not being recognized. I tried multiple options such as holding down "C", "c", "option" key etc while the system is restarting. Only the main disk was being shown as the bootable option (while holding down the option key when restarting) but not the rescue disk.
I verified that my rescue disk is good. Infact, I could boot a Lion MacBookPro using my resue disk.
Any inputs are appreciated.
Thanks
gb

It was 10.6.4 (Snow Leopard). It was the same as the rescue disk version.
thanks

How to force boot from an external disk

My main start up disk has crashed. I have made a cloned disk using Super Duper that I have checked recently and the computer will boot from it. I also have another OS 10.6.3 on another internal disk.
I now want to boot from the cloned disk but the computer always defaults to the internal disk. I have tried using Start Up Disk in sys preferences. I have tried starting up with the option key held down.
Is there anything I can do to force the computer to start from the clone disk?
One other thing, I installed a 1TB Western Digital Caviar Black drive to replace the crashed start up disk but Disk Uitility won't initialize it.
The computer is a 2007 Xeon quad core on OS 10.6.8.
Thanks

I got this, I think I did it right, not much into the terminal

How to boot from FireWire disk?

I have made a copy of my main disk with CarbonCopy, using an external FireWire 800 disk. According to CC it should be bootable, but pressing Option during boot does not show the that disk as boot option. When I boot from the main disk and try to change the boot disk in Preferences, I get this message "You can't change the startup disk to your selected disk, the bless tool was unable to set the current disk".
Why am I doing this? I bought a 500GB disk to replace the 200GB internal disk. Wanted to restore the original content from the FireWire disk after swapping out the old disk. I could also restore from a TimeMachine backup I have on a USB disk, but that will take much longer and I have had issues with complete restores from TimeMachine backups in the past.
All recommendations are welcome

It sounds like that you didn't format the hard drive properly. If you want a bootable hard drive with an Intel powered Mac, you must choose the "GUID" partition scheme.
Use Disk Utility to verify whether your external hard drive is partitioned with GUID scheme or the Apple partition scheme. If the later, you'll need to reformat with the GUID scheme.

5 mins+ to boot, can't repair disk

Hi
My 24" Core 2 Duo has started to experience problems when I power it up. I usually leave it on all the time, but recently when I restarted it, it took nearly 20 minutes to reach the login screen, and then at least 20 minutes to open the startup items.
I rebooted in Safe Mode successfully. I ran a Verify Disk on the startup disk using Disk Utility and it failed, recommending a Repair Disk. I booted from the install disk and ran Disk Utility. The start up disk is shown on the left but the volume "Macintosh HD" is not listed under it, so I am unable to run Repair Disk.
After reading http://support.apple.com/kb/TS1417, I am not sure that I should attempt to run fsck. In any case I am not sure how to boot into the command line.
I have also run the Apple Hardware Test twice which gave the following error codes:
4SNS/1/40000001:VGOR-10.832
4SNS/1/40000001:VGOR-10.789
I have also reset PRAM and NVRAM.
Other than the 5-10min boot up time, the machine appears to be working normally. The disk's S.M.A.R.T. Status is Verified but I really want to run Repair Disk, so that I know whether to replace the hard drive.
Any ideas?
Message was edited by: tinysausage

Dave, you may well be right in the long run, but I have managed to get it going again for now. Here's how:
I booted to command line in single user mode (command-S on startup) and ran fsck:
/sbin/fsck -fy
This gave an "invalid index key" error which fsck was unable to fix, despite running several times. A Google search of this error suggested that it is a pretty severe corruption of the directory catalog, and that total data loss was imminent. So I bought DiskWarrior and ran it on my MacBook connected by FireWire to the sick iMac in Target Disk mode. DW came up with lots of errors, and created a new "optimised catalog".
A reboot later, and voila!, the iMac boots up in under a minute. Now let's hope it lasts...

Booting from a Firewire Disk backup - get Startup Manager to show FW disk

Hi all,
A hint that I have discovered whilst trying to create a backup on a Firewire external Hard disk and boot my eMac from it.
eMac 1.0GHz (ATI), OS X Tiger 10.4.7 and OWC Mercury Elite Pro 40Gb firewire external disk (Oxford 911+ chipset)
I created a bootable backup using both Carbon Copy Cloner and/or Rsyncx on the firewire disk, but with the same results each time - it woudn't boot from startup manager. I was careful to make sure that the disk was bootable and it would boot from the FW disk after selecting it in system preferences/startup disk and restarting. O.K so far.
OS X also offers an alternative boot method using the startup manager at boot time which you can enter by holding down the option key while turning on the eMac until the startup manager comes up. Normally it shows your "macitoshHD" and "repair" hard drives and you can select the preferred boot up drive. According to Apple help it should also show bootable Firewire disks, but I could not get this to happen.
After a bit of trial and error, I found this sequence reveals the FW dive.
. Make sure your firewire external drive is turned on and plugged in to a firewire port on your eMac.
.Power on the eMac whilst holding down the option key (The key with the apple and squiggley thing next to the spacebar)
.Keep holding the option key until the startup manager icons appear.
.Once the startup manager appears, it will take about 30 secs to 1 min to scan for drives.
. Usually icons showing your internal bootable drives will show along with a rescan and continue icon.
. To get the FW drive to show, hold down the option key and click the rescan button (the turned back arrow icon on the left)
.The system will then rescan and find the firewire drives and show their icons as well as the internal drive icons.
. Select the firewire drive (You did give it a unique name didn't you?) and the click the continue arrow on the right.
. Watch the FW drive activity light and you should see lots of flashing and there you are - booting from the FW drive.
I couldn't find any reference in all the help references to holding down the opt key to rescan, so maybe it is peculiar to this eMac?
Give it a try and be sure to let me know if it works for you.
Ian

OK JMVP, but there is something a little strange here.
After I booted the system whilst holding down the OPTION key, startup manager appeared and scanned for drives but only showed the normal internal drives. (By this time I had already released the OPTION key). I clicked the re-scan icon and same thing, still no FW drive. According to all the Apple help files it should show the external FW drive as well.
But, when I held down the the OPTION key and clicked the rescan icon again, it rescanned and showed the internal drives AND the FW drive. Maybe it's an undocumented feature of startup manager, maybe it's peculiar to the FW drive I'm using
I will try to update the firmware, but the manufacturers website says it doesn't need updating to work with Tiger. Other than this minor prob it already seems to be working OK. Just won't show up in the startup manager without rescanning with the option key pressed.
I did notice whilst searching the help files that there is another option to boot from external drives:
Hold down Option-Command-Shift-Delete keys during startup - this will Bypass primary startup volume and seek a different startup volume (such as a CD or external disk). It didn't work in my case.
Curious?
eMac (ATI) Mac OS X (10.4.7) Mac Newbie

System is stuck on "repairing disk errors" loop

I have a Dell Inspiron M531R - 5535 windows 8 (or perhaps 8.1) that's a year old. It's been working fine until today. Last night I think i might have over heated but doubt it seeing as it didn't shut itself down like it usually does if it over heats (but it still might have idk).
I went to start it up today and it was stuck on the Dell loading screen for about 15 minutes. I restarted it using the power button and it took me to a "repairing disk errors" loading page. I waited seeing as it said it could take over an hour but after 3 hours I tried it all over again and waited ANOTHER 5 hours and it's still stuck on that loading screen. Twice it's gotten my hopes up by taking me to my sign in page but it won't let me type or click anything and just freezes there.
So, I tried to reset my pc back to factory mode in hopes that it would fix the problem. I've pressed every function button with the power and the only ones that work are the f5 and f8 button. They booth allow me to either pick setup or boot options. Neither one gives me the option to put my laptop in safe mode nor restore/repair. I even took the battery out and put it back in and it still does nothing.
To top it all off, I don't have a windows 8 recovery cd and have no idea how to get one (I don't know anyone else who has a windows 8 or 8.1)
Is there ANYTHING that can be done or should I take my laptop in to get repaired? Or the worst news of all, is my 500 dollar laptop done for good?

Repairing disk errors is a process that will take a long time. It will appear to be stuck but this is normal most of the time depending on what it is repairing. Give it more time until fixed or you get another message.
Please mark my post as SOLVED if it has resolved your problem. It helps others with similar situations.
