Can't boot to all my partitions?

I have a few partitions on my mac, the default OSX partition, running snow leopard, an Ubuntu partition, and I just created a pair of Arch linux partitions. When I boot holding option, only the Mac and Ubuntu partitions come up (also the archiso CD). I made and mounted the ext4 partitions on /mnt and /mnt/home, and installed Arch properly. Everything worked wonderfully. Except, I can't boot the partition except through the CD. Does anyone know if there's a way to resolve this issue?

Hi,
Did you install a bootloader?

SSD in MBP 13" Retina Late 2013 doesn't work - Can't boot at all

I have a new MacBook Pro 13" Retina which works flawlessly. It has a factory installed 512 GB SSD, which also works flawlessly. Then I bought basically the same type of 512 GB SSD, 2nd hand but new, which I intended to install in another MacBook Pro Retina Late 2013.
The seller told me it is compatible with the MBP Retina Late 2013, but when installed, the known to be good MBPR doesn't boot. Not from that SSD, not from an attached USD HDD which has two perfectly bootable Mavericks partitions. When pressing the alt-Key on booting, I can however see two partitions on that SSD (Mac OS X 10.8.4 and a Recovery Partition), yet it is not booting at all, thus also doesn't allow me to inspect or treat this SSD with Disk Utility or other tools.
All I get is the grey screen with the striked through circle sign (see attached image). I've tried both, PRAM reset and SMC reset, no change.
Here comes the interesting part: Although both SSD look identical, they have slightly different model and part numbers (see attached image).
Working, factory installed SSD: Model MZ-JPUS512T/0A6. Part No. 665-1805D
Non-booting, 2nd hand SSD: Model MZ-JPUS512T/0A2. Part No. 665-1805A
Any ideas what’s going on here and how to solve this?

Excellent point! Mac OS X 10.9.1 doesn’t equal Mac OS X 10.9.1!
Back in the bad old days of Mac OS X Install DVDs, I was aware of the fact that there were different versions of the OS X Installer testing against the Mac ID to make sure that bundled versions get only installed on those Macs which the DVD came with. And the DVD where clearly labeled in that sense.
Now in the days of Internet download and installation from USB sticks, SSD and HDD, one completely forgets about this. On the other hand, with Mavericks being free, I don’t understand the need for such limitations, and not at least the recovery partition allows booting any Mac which supports Mavericks.
When you boot with the alt-Key pressed and you see at least one partition with Mac OS X 10.9.1, one just doesn’t understand why the heck the Mac doesn’t boot. Now I do. Apple would be well advised to simply add a short info line, like „This version of Mac OS X is missing components to boot this Mac. Please re-install from the AppStore using this computer“. It would take out A LOT of guesswork.
Anyhow… I booted the MBPR using the working SSD, installed Mavericks from the AppStore on the external USB HDD, switched the SSDs, booted from the external USD HDD’s now bootable 10.9.1 Recovery Partition, wiped the suspicious non-booting SSD and installed Mavericks. No further problems. (Completely forgot about the CMD-OPT-R Internet Recover Mode keg55 has mentioned…)
Thanks for the hint!

10.4.6 - can't boot from OS 9 partition or start up disk anymore ??

I have an OS 9.2.2 partititon as well as my 10.4.6 partititon on my main HD, plus a seperate HD which has 2 partitions on it. I have a Digital Audio G4 which has a Powerlogix 1.4Gb 7457 cpu in it.
I use my Mac for music. I want to boot up in from the 9.2.2 partition to run Nortons to defrag my other HD which I use to save all my audio files on. My Nortons will not run in Classic mode.
I haven't done this for a while, since 10.4.4 I think.
So no matter what I try, I can't boot up from my OS 9.2.2 partition via Start Up disc OR from my Nortons OS 9 start up CD. I just get a grey screen after the start up chime. Start Up Disc in 10.4.6 recognizes the OS 9.2.2 partition...
I really find it difficult to accept that 10.4.6 should stop me from being able to boot up from the Nortons disc but that is what it is starting to look like to me.
I can still use Classic mode in 10.4.6 and run OS9 applications in Classic.
Is it a 10.4.6 issue and would I solve it by downgrading to say 10.4.4 ??

Hi Murray;
I disagree with your comment; "I appreciate
Nortons is "ancient" but that's not really the
issue.".
I think it could very well be the issue. > Allan

Thanks Allan. With all due respect I can't understand at all how Nortons could be the issue, at least so far as it relates to the bootable CD I have with 9.2.2 on it.
This morning I tried booting from the System disc that came with my G4 when I purchased it. It has a 9.1 System folder on it.
The start up disc preference in 10.4.6 recognized th 9.1 disc as an option but, just like trying to start from my 9.2.2 partition and the Bootable disc with 9.2.2 (and Nortons 6.0) on it, I could not get past the grey screen.
I was able to boot from the Apple Hardware Diagnostic disc or whatever it is called and the test results said that all was well.
I am at the office now (heaven forbid using Windows) but when I get home tonight I am actually going to try zapping the PRAM because I am staring to think it may be that.
Funny, zapping the PRAM used to be a standard tool in my OS7/8/9 days...kind of forgot it as an OSX tool but I have a funny feeling that might actually be the problem.
cheers

Can't Boot from Snow Leopard Partition

I have a Macbook Pro from 2008. It previously just had one partition, with Lion on it.
I created a new partition for Snow Leopard
I installed Snow leopard from a retail disk on the second partition. The installation went fine, and I got the message at the end that the installation was successful, and to restart the computer.
When I restart it, it just goes to the gray Apple screen, with the spinning gear, and never gets farther than that. The gear is spinning.
I can still boot successfully into Lion. Once I booted into Lion, I chose the Snow Leopard partition as the Startup Disk, but the same thing happens - just the gray Apple screen and spinning gear. I've let the machine sit for half an hour in that state, but it still does nothing but the spinning gear.
Any ideas on why I can't boot successfully into Snow Leopard and how I can fix it?
Thanks.

I already knew that I'm free to follow my own course, but thanks for giving me your permission (???)
And would knowing the original OS of the machine make any difference in your "advice"? If it was originally Leopard, would that make it any different than if it was Tiger? Answer: No, because you don't understand the problem, and you don't know how to fix it.
Thanks.

Can't boot from OS X partition

My Macmini can't boot from the OS X partition, but when i try to boot using the windows partition it works just fine. I've also tried to boot from the instalation dvd but it doesn't work either. When i turn it on, right after the gray apple appears it shuts down. Is there anything i can do besides formating the entire HD?

Your question seems to be a MS Windows question. If you use Boot Camp then post there. If you use Parallels or another virtualtization app to run Windows please post in those forums. Most users on this forum don't use Windows, some do but most do not.
Best of luck.

Can't Boot neither from Recovery partition or CD recovery disks

Hello everybody, I already purchased Laptopo with the following specifications:
- HP Pavilion DV6-6160 SE Entertainment Notebook PC
- Operating System is windows 7 64-bit
- Error message : an error occurred while attempting to read the boot configuration data (File: \Boot\BCD & Status: 0xC0000225)
- After I purchased it I created the recovery CDs, then partition the C drive into two partitions by using EaseUse partition manager, the D partition which is for recovery still as it. after 3 weeks from that the above mentioned error occured while I were retarting the windows. Then I insert the the recovery CD and change the rebooting sequenc to be CD-room first then Hard disk but the error still exist with the same message, also I tried to count on the recovery drive which on the hard disk as I power up the device and press the F11 to boot from the recovery drive also nothing happened and the error message still exist.
I don't know how I can solve this problem the device still under warranty, Have recovery CDs, Recovery drive (D) is still exist but nothing can solve this problem
Finally I would like to inform you that I can access the windows 7 from safe mode, and I uninstalled all programs I have installed on it and try to restor factory setting but the device reboot with the same error
Awaiting for your kind support
Regards

Try booting into Safe Mode and use Disk Management to delete the extra partition you created.Reboot at least once before trying F11 again to see if it will work.
If no joy, you might also enter BIOS by tapping away at the F10 key immediately after powering on.Reset BIOS to Default settings then F10 to Save & Exit.

10.5.1 - Can't boot at all from volume anymore

Installed 10.5.1 onto my MacBook Pro using Software Update. Left my computer to eat some dinner. When I returned, my computer had auto-rebooted, but into Windows on my BootCamp partition. I tried to reboot into MacOS, but when I hold down alt/opt on boot, the Windows volume is the only one available! Booting from the Leopard DVD shows me that the volume works fine, and when I select it in the installer, the installer says that a newer version than 10.5.0 is installed on it.
This is different than the other threads I've seen in that I don't even get to see the apple logo -- it's like the boot loader doesn't think there's a system on the volume at all.
Of course my Time Machine backup is a few weeks old, so that's unfortunately not an option. I've tried zapping my PRAM, holding shift while booting, but neither works.
Anyone has the same problem or has a solution? Or at least an idea of what could be wrong? I know my way around the Terminal, so if you happen to know some files I should try to restore from another 10.5.0-running machine or bless something or something like that, I'd love to hear it.
Thanks,
Joachim

Problem Solved without Archive and Install!
You need a second Mac Though...
I didn't want to install via "Archive and install, costs me about half a day reinstalling the software and other stuff.. So I thought about something else!
I originally installed the update via software update.
I now downloaded the 10.5.1 update from the applesite (110MB) on my Macbook. I hooked up my Mac Pro in Firewire Mode, (hook up your Mac via a Firewire cable and boot pressing T, The Macintosh HD of this computer will appear on the desktop of the Macbook)
I installed the update via my Macbook on the mounted Mac HD from my Mac Pro.
Re-boot, all problems fixed! (less than 10 minutes including downloading)

Can't boot into windows 7 partition after updating to 10.10.3. [MBP-mid 2014]

[SOLVED]Can't boot at all

Hey,
i'm new on archlinux so i pick a USB key, and launched it.
Then i get a "classic error" but a bit particular at the same time. Here we go :
::Mounting ‘/dev/disk/by-label/‘ to ‘/run/archiso/bootmnt‘
Waiting 30 seconds for device /dev/disk/by-label ...
ERROR : ‘/dev/disk/by-label/‘ device did not show up after 30 seconds...
Falling back to interactive prompt
I searched a bit, and i could only find theses kind of case where we knew WHAT he is actually trying to mount (https://andym3.wordpress.com/2010/12/16 … rch-linux/), here i just find "..." instead of "ARCH_randomName".
Any idea ?

Hey again,
and sorry, i assumed this "scheme" was something usual, somehow.
I'm on a fresh assemblated PC :
CPU : AMD Athlon X4 750K Black Edition
MB : ASRock FM2A75 Pro4
GPU : Zotac GeForce GTX 650 Ti 1 GB
Everything is new, as is it for the hardrive.
And gosh i'm so dumb, i forget the centerpart : the lines i get first while booting :
[2.834428] [drm] nouveau 0000:01:00.0 : 0x8B9E : Init table command not found : 0xA9
[2.834429] [drm] nouveau 0000:01:00.0 : 0x8B9E : PGRAPH: unsupported chipset, please report!
Does it mean something like this AMD thing isn't compatible with the last review of Arch, or is it something that i can go through ?
(Also, i'm affraid i'm not carrying the best english. This is not my main langage ^^)

Can't boot G5 even from OS install disk. Help?

I've trolled the message boards 25 pages deep and searched all the "Can't boot my G5" threads and still haven't found anyone describing what my machine is doing so thought I'd start a new thread in the hopes someone can help me out.
Ok I have a G5 dual processor machine. (Power PC chip, not Intel) Things went bad when I tried to do an Archive and Install of Leopard (OS 10.5) The install looked as normal until I got to one minute left on the install. At that point the install never progressed. I thought maybe it was doing some behind the scenes processing and decided to leave it over night. The next day my machine was still hung on that One minute left. So obviously it was a failure. Of course now the problem is I have an install that never completed of the OS and so that partition is, I assume, unbootable. Wiped away the Tiger OS and did a 99% install of Leopard. So I had to shut down by holding the power button.
I think to myself, "No worries I can just boot from my 2nd partition holding down the Option key to select it on the boot up screen". I always keep a partition with an OS on it for times like these. So I reboot, hold option key, select my other partition, things look OK. I get the grey screen with the Apple logo and I get the wheel animation turning. (Not beachball of death but the typical circular, almost sun ray configuration thing) At this point, usually the screen will go black for a moment before the desktop loads. However, in my case once the screen goes black after the load screen, it stays black. Now let me say the monitor does NOT turn off. There is a definite difference when I manually turn the monitor off. When off it's truly black. But this is like a power on black, not true black. (If you need me to explain this better feel free to ask me to clarify)
So the untouched, pristine Tiger partition boot is a No Go. I figured I'd then give up on trying to put Leopard on my desktop machine (I use it on my laptop) and reinstall the original OS and system software from the system disk that came with my G5. I boot machine holding down eject button, place the disk in, close the drive door and shut down again by holding power button. Reboot holding C key and the same routine happens with booting from the disk. Gray Apple logo screen, sun ray circle moving, screen goes black on the attempted transition to desktop .. but stays black. I also tried booting with my Disk Warrior disk to no avail. Same thing happens. (Also tried booting from disks by selecting them manually from booting with Option key down) At first I wondered if it was a monitor issue. That maybe my desktop was up but there was an issue with the signal being passed to the monitor on the resolution jump. Thought perhaps hitting the Eject key on the keyboard when I had attempted to boot from the partition (not from disk on this test) would tell me if it was a monitor issue. If it was a monitor issue, the disk tray should open. But alas, no.
So since I cannot boot normally from any partition or disk I decided to boot into single-user mode.
I did the fsck -fy thing and it told me everything was ok. I had also previously installed applejack and I ran that and short of correcting a few permissions and dumping some unneeded caches it came back with a system OK.
At my wits end I booted into target disk mode and ran Disk Warrior on both the original half installed OS partition and the back up emergency boot up partition from my laptop. Again, everything OK. Hoped against hope that I could actually install an OS onto my G5 from my laptop but I was only given the option of being able to do it from my laptop with the Leopard disk and it would only allow me to do it if I used Disk Utility to completely format that drive first. No, thanks.
Re-attempt to boot G5. Failure. So now I turn to hardware. Disconnected everything beside the keyboard and mouse. Try again. Fail. Pulled a couple sticks of Crucial memory out of the machine and left the stock RAM. No dice. Pressed the small power unit reset button under the RAM slots. No change. Zapped the PRAM. Still nothing. Try to boot in Safe mode holding down shift key. Doesn't work.
It seems to me if I can't even get the machine to boot from the Install disk that there is something going on that is much more major than software issues.
Bad motherboard? Any ideas? Because I'm all out of ideas.

Brother, Sound74, I thought I was the only one pulling the hair out of my chest one by one the past two days. Your situation is very similar to mine, and I'm just as clueless as you are. I started getting kernel panic screens, then nothing on boot, until finally I brought it to the local genius bar. They ran all the usual software/hardware tests, updated Tiger to 10.4.11, recommended I buy Leopard and do an erase-install. My computer, of course, was working absolutely fine by this point. I bought Leopard, came home, backed everything up, then tried to install the new OS. Like in your case, it just up and quit half-way through. Screen went black and a "No DVI Signal" message came on my display (it does this when I turn it on without first turning on the computer).
So I thought, well, maybe it takes a really long time to erase-install, and the monitor is just waiting for things to kick back in. I've always upgrade-installed before, so I couldn't tell if this was normal or not. But about half an hour later, my fans kicked in so fast I thought I had a P-51 Mustang taking off in my studio. I waited a bit more and finally force-shut-down my system. Not knowing what to expect, I nervously tried to re-boot.
Nothing. Zip. I can't safe boot, I can't boot from the installer disc, etc. The only thing I can do is the option-key thing whereby you choose the startup disc. And of course, it only gives the Leopard install disc as an option, because now the entire HD has been erased! But when I choose the Leopard disc, of course it doesn't work.
So I have a nice $3000 paperweight sitting in my studio. I guess I'll have to bring it back to the Mac store, where if it costs more than $300 to fix, I'm going to say screw it and put that dough toward a new iMac.
Sorry I couldn't provide any helpful info, but I just wanted you to know you're not alone in suffering the slings and arrows of outrageous technology.
Keep me posted on any solutions you discover, and I'll do the same.

PS My applecare expired a month ago! AAAAARRRRGGGHHHH!!! **** Murphy and his stupid laws.

How can I get my OS X back to my MacBook Pro? Booted Widows 7 from a disc and have deleted all the partitions. :(

Guys! I'm new to OS X and not used to it so I tried installing Windows 7 having the thought that it's as easy as on ordinary laptops. Installation was succesfull, Installed it by first going to a "boot utility like" screen while it's still on OS X, Deleted all those partitions, Placed a Windows 7 disc in the disc drive and on the Windows installation menu I also deleted the partiotions I saw. After all that my MacBook successfuly is running Windows 7 but problems appeared like no backlight on the keyboard, Trackpad is no longger functioning well and the audio jack has this f*cking red light. :'( I admit this is all my fault and I really need to find a solution to get it running on OS X again. Please help!!! Sorry for my bad english... And also, While booting up, There is no more Apple logo but a silver screen then Windows...

A partition is just a section of the disk set aside for a particular purpose. In this case, we're talking about a Mac partition and a Windows partition. They have different formats, which is how the data is stored. The disks that came with your Mac will create the Mac partition when you install, but most likely you'll lose the Windows partition. You've got kind of a mess at this point. What you should do is install the Mac OS and get everything as you want it. Then run Bootcamp to create a Windows partition and let Bootcamp do the Windows installation for you. Grant gave you good advice earlier. Don't let Windows do any partitioning. That's how you got into this mess.

I partitioned my MacBook Pro and installed Windows 8 in it.....now I can't find my partition when I pressed option key when booting up.....so how can I do to find the partition to boot...I can see it in the disk manager in Mac....any ideas? thanks..!..

Hi LamboMong,
just try this:
http://refit.sourceforge.net
install, reboot twice and choose the Windows-Partition on next startup.
(The apple-bootloader doesn't display all bootable harddisks.
With rEFIt you can boot from all partitions/harddisks on your computer.)
I hope that will solve your problem.

Imac G3 had clean install OS 10.1; can't install 9.2; now won't boot at all

Hello,
I was given an older imac G3--has 176 mg ram; 6 gb hard drive. Due to its small memory and the fact my daughter just wanted it for games, I decided to only install OS 10.1, instead of OS 9.2.2 and OS 10.1.5 which I have on my G4.
Then, I found that most of my CD games (no internet access) need Classic to run. So, upon inserting my OS 9.1 disk to install that, I got the message that the firmware needed to be updated; then an error saying I needed installer 4.5.5.
Two questions:
1. How do I get around the fact that my firmware needs to be updated but when I boot from a locked disk, I get the error message that firmware updates can't take place due to locked disk.
2. Now, I can't get it to boot at all into OS X or any disk in the CD drive--I get a screen with a little script that says, "failed to boot, etc., Apple Firmware 3.0 3f built 12/__98
then (not exact text)
0 >boot MAC-PARTS: specified partition invalid, etc.
can't open ide1, etc.
I hooked it up to my other G3 imac and my G4 via ethernet cable but since there's no system accessible, I can't turn on file sharing/Apple talk, etc.
Hoping I'm not the only night owl going round and round with these kind of problems. Any help would be much appreciated.

If you don't mind wiping the hard drive, boot from the 10.1 installer disk and install the 9 drivers:
http://docs.info.apple.com/article.html?artnum=75275
Then find out what CD came with the Mac by first identifying it:
http://docs.info.apple.com/article.html?artnum=58669
And then looking at this article:
http://docs.info.apple.com/article.html?artnum=25517
If it came with 9, get the original CD that came with it to install Mac OS 9.
If it came with Mac OS 8.6 or earlier, get a retail 9 CD which looks like
Do a clean install using
http://docs.info.apple.com/article.html?artnum=58176 as a guide once you have the correct 9 disk.
Then install the firmware update that corresponds to your Mac:
http://docs.info.apple.com/article.html?artnum=86117
And then I would not even bother with 10.1.5 anymore and get 10.2. Repairing issues with 10.1.5 is difficult. 10.2 installer disks which work on that machine once the firmware is updated look like

Can't boot into Windows 8.1 partition after apple store repair

Can't boot into Windows 8.1 partition after apple store repair
I went to the apple store about a week ago to get my screen fixed, and when I get it back I don't have an option to boot into my windows partition. The bootcamp partition is still there, but I can't boot into it. I can still see all of the files on the drive. When I try to boot into windows from the startup disc setting I get "no bootable device — insert boot disk and press any key” on a black screen. I went in for a dead pixel, and the guy at the genius bar ran something on my computer and went into disk utility application. I’m not sure what he was doing, but obviously that’s what messed up my windows partition. How can I be able to boot back into windows? Here's what disk utility looks like on my computer.

Here's the output
