Laptops :: Startup Disk Error - Cannot Boot To Mac Partition
Apr 17, 2010
I partitioned windows XP onto my Mac HD a few days ago. It worked beautifully until last night. Whenever I booted to it, it stuck at the welcome screen for 10 minutes, and was really buggy upon startup. This morning, my MacBook Pro (bought in August '09) upon turning on automatically boots to windows XP. No amount of holding "c" or "Alt" will bring up rEFIt or boot camp selection pane. And the kicker is, the windows XP partition is completely corrupted.
Here's what happens now:
1) Turn Macbook Pro on, hold down "c" or "Alt"
2) White background for ~ten minutes, nothing happens
3) After a long time, boots to black screen and says "Startup Disk Error... Press Ctrl+Alt+Del to restart.
I'm pretty sure its trying to boot to Windows XP partition, because Ctrl+Alt+Del is not a Mac OS X command... But I can't boot to my Mac OS X partition.

Got my first MacBook Pro about 2 months ago and I have been enjoying it to full effect, installing programs such as logic studio and photoshop cs5 on it. Recently, however, I decided that I would like to access some of my windows based programs when I am on the road and don't have my desktop pc with me. So I bought a fresh copy of 32-bit Windows 7 Ultimate and sat at my macbook, put the disc in and then loaded up Boot Camp. I went through the menu options, decided that I wanted a 50GB partition, leaving my Mac OS drive at 182 GB with 83GB to spare. However, when I started partitioning, after about a minute it stopped and this error message appeared: "The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.".
I tried cleaning all my temporary files and deleting some files in my downloads that were quite large and I restarted my machine. The problem persisted. Is there a solution to this problem that does not involve doing all this rubbish with a fresh install of Mac OS? I don't have any method of backup apart from a couple of 4GB flash drives..

My mid 2010 iMac i7 will not boot past the apple logo? I'm running 10.7.3. I have tried restoring from TM backup from recovery mode (worked the last time this happened) however upon completion it returns to the recovery screen? I made a disk of Lion when I downloaded the first time (followed same instructions sourced from numerous websites) which does not seem to work when i set to start up from this disk, just gets to the grey screen and flicks between the apple logo, a folder icon with a question mark and the circle with line through? Now I can't eject the disk either, a message appears that system can't eject and to make sure all applications are closed? Not sure how to go about closing these applications without being able to start the system? When I tried booting from the Macintosh HD I got a message that the boot cache partition was faulty? I have ran disk permissions etc all ok. Â

iMac, Mac OS X (10.7.3)

I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)

Not quite sure what happened, but somehow part of my OS X partition became corrupted and is no longer recognized as a startup disk. I ran techtool pro and tried to repair the volume from there without luck, then ran a Leopard install DVD and ran disk utility's repair disk twice (first time came back with an error, second it was able to complete and fix all issues). Where I'm currently at. I am able to view all of my files via Macdrive and my Bootcamp XP partition without issue and am currently backing up any files I hadn't previously backed up. My question is, will I have to do a full reinstall of OS X or is it possible to somehow activate the drive as a startup disk or diagnose where the problem lies and address it?

I have Ubuntu 9.10 (Karmic) installed on my MacBook Pro 3,1 as well as Mac OS 10.6 (Snow Leopard). Is there a way to set the startup disk as the Ubuntu partition (ext3) so that I don't have to hold option or use rEFIt?

As soon as I start the Bootcamp assistant I get this message on the screen that asks for download of the windows support files - ie right at the start.The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.

I installed Ubuntu on my iMac, and it made 2 new partitions: DISK0S3 and Linux Swap. Here's what my disk utlity looks like: When I try to remove Linux Swap, it says that the partition (map is too small. When I try to remove DISK0S3, nothing happens and it keeps running forever before I press +Q to quit.

I just restore my Mac OS to a single partition and then I tried re-partitioning but it's giving me an error.
I've tried several times, tried using different sizes every time. My HD's capacity is 250GB, and I've got 108.95GB free. So I am sure that making a new partition of 35 - 40 GB is not a big deal. I also tried using Disk Utility, both from the Mac OS install disc and while using the Mac OS itself, but it keeps giving me this error. I do not want to format my Macintosh HD's partition because I don't have an external HDD on me at the moment so I will not be able to back up. I have a lot of important data that can not be deleted.

When i boot into Vista at the boot ing Windows Vista black screen, i get an error message that says... Warning: unrecognized partition table for drive 80. please rebuild it using a Microsoft-compatible FDISK tool(err=4) System tyhpe is NTFS, partition type 0x7 then it goes, and lists that a couple more times, then it boots into Vista. I just had an internal drive crash, so I purchased a 1TB and installed it into my 2ghz iMac. Everything went great, and now I am in the midst of reinstalling all my apps. I then partitioned the drive for 53 gigs with Boot Camp and installed Vista 32bit with sp1. And when I boot into the Boot Camp partition, that is the error I get, but then it finally after listing that about 4 or so times boots fine into Vista. I have installed many things now on that partition under Windows and everything seems perfect with it, it is just I get that error.

am not sure if I am posting this in the right category. I am new on here so forgive me if it is not in the right place. I am having trouble with my partition using boot camp. I am getting an error about the files not being able to be moved. I have repaired permissions... did not work. Defragmented.... did not work. When I look at the defrag log I see that there is an error -43 on a jpg, which I can not find. All the other errors are items running that pertain to actually the computer working (quit all files that were opened just to make sure).

I had my hard drive partitioned via bootcamp to run windows vista. I use software at work that isn't supported by Mac (it is now, but our version is old and it costs 10k to upgrade yada yada yada). One night I was playing around with the time machine feature (had the macbook for three years now never touched it, wish i hadn't) and accidentally told the time machine to use the partition made by bootcamp for windows to back up my mac. Well this messed everything up. Now that partition is gone (windows) and that volume is now called time machine backups. I have used some threads in here to try and remove that and nothing seems to work (most of the threads are from 2007 to 2008).
What I need help with is removing that time machine volume so that I can run bootcamp again to reinstall windows. When I attempt to run bootcamp right now it says "This startup disk is not supported." When I restart and hold option only the mac hd is available to choose. I also use(d) VMware Fusion to run Windows.

"The disk cannot be partitioned because some files cannot be moved. Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again." Does it really mean I have to partition my whole hard drive and then reinstall everything? I'm hoping I'm just misinterpreting....
I have had my uMBP for about two weeks, I boot camped, decided I needed more space for windows, used Winclone to clone my windows partition, merged the windows partition back into OS X, and now I get an error message when I try to repartition. Please tell me there is an easy fix. BTW, my harddrive is 250GB, there is 87GB free, and I am only trying to create an 81GB partition.

Right now I am booted into the GParted live cd, and I am wondering if my computer will even be able to boot into the OS X install disc if I delete every single partition on my HDD. I am going through a roundabout way of removing ubuntu. Will I be able to boot into the OS X install disc and do an install if I delete every single partition, and leave my HDD completely blank and unformatted?

I have an alu iMac with a 500GB HDD. There is about 200GB free. Every time I run the Bootcamp Assistant, choose a Windows partition (doesn't matter what size), it sits with the progress bar spinning for ages before it gives me the error "Disk could not be partitioned as some files cannot be moved. Please reformat the disk and try again". There is no way I can back the disk up, reformat, reinstall and re-update everything. No other apps are running when I run the Bootcamp Assistant.

My Finder says that I have about 50GB free, Disk Utility says I have about 20GB free, and Boot Camp says I have less than 10GB free. I ran a Disk Verify in my Mac OS Partition, it says the OS disk is corrupt. I went to the Recovery Partition, it says everything is fine. What do I do to fix these issues?

Im trying to partition my Macintosh HD and install FCP X on the new partition, because I want to still use my Final Cut Studio when needed. I want to install MAC OS on the new partition so I can use it as a start up disk as well. I followed the instructions as directed.
I restarted my computer and held the command and "R" key. In the disk utility I selected my HD and selected 2 partitions. I named them and entered the size and selected GUID as scheme. but when i hit apply i get " Failed, cant unmount disk" how I can successfully partition my HD.

I have a Lacie 1TB external drive. I'm trying to create another partition on it using Disk Utility so that I can use one of the partitions for Time Machine. When I go to add another partition, or even just resize the existing one, I get an error saying drive must be HPFS+ with Journaling enabled. It is. I've seen reference to this error in searches, but have not found a solution. Is there a fix for this, or another tool that I can use to re-partition my drive without wiping out existing partition? I have about 450GB worth of data on the drive that I might be able to store somewhere else temporarily, I would just prefer not to have to go through that....

I deleted my Boot Camp partition in Disk Utility (as usual, Windows wasn't working and wouldn't fix). I resized my Macintosh HD partition to cover the whole drive and repartitioned. Now Disk Utility says that the partition's capacity is 160 GB and that I've used 40 GB and that 70 GB is available. My Boot Camp partition was 50 GB. I've read that to fix it I have to boot from my install DVD, go to Disk Utility, set the number of partitions to one, and delete the entire drive so that there's zero data left. Then I'd reinstall OS X and restore from a Time Machine backup. As of now, I have no external hard drive.

I tried to install Windows Vista (64bit) using Boot Camp. I get to the window where you select the disk partition you want to install Windows on, and there aren't any options. How can I get the newly created partition (the one I made with Boot Camp Setup Assistant before restarting) to show up on that list? Or, where do I find the "driver" that it requests instead?

I have a new MacBook Air running Lion. Every time I use my backup software, it changes the permissions on my external drives, and I have to change them from read only to read & write, so I've gotten in that habit. At one point, I noticed that the permissions on my internal *startup disc* were read only, so I (foolishly, I now know) changed the permissions on the startup disc to read & write, with apply to all enclosed items checked. As I continued working, I got messages that a number of extensions could not be used and will be disabled (or something like that). I decided to reboot, so the computer could reset and hopefully correct things.
When I tried to boot, it hung up on the grey screen with the Apple logo and the spinning clock/gear. I let it spin for a while, then forced power down and tried to boot in safe mode. The progress bar appeared as it's supposed to, but when the progress bar finished, it went back to the grey screen and hung up again. I let it spin for over 40 minutes before powering down, just in case it was doing diagnostics or something. I don't have access to the original OS DVD (nor do I have an optical drive to put it in). Any way for getting the computer to boot, at least in safe mode?
