Windows partition no longer available on startup disk tool
I can no longer see my Windows XP partition from the startup disk tool.
The WinXP partition was created with bootcamp, and it was visible ok on the startup disk. Now it is no longer visible, although it keeps working if I select the partition at startup using the Option (Alt) key.
I suspect the problem is related to the fact that I have installed NTFS-3g and MacFUSE to make the WinXP partition read/wirte, but I have no evidence that this could be the root cause of my problem.
Any hint?
Thanks,
Fede
Hi, me again.
When you found the setupact.log file (from the other thread) did you do a search for "detected boot environment"?

Windows Partition No Longer Shows Up After Accidental Premature Closing of Camptune
Mac OS X 10.7.5
I was running Paragon Camptune to expand my Windows 7 partition. The progress bar reached the end and stayed there for about 30 minutes. The Camptune window was then accidentally closed and Camptune quit itself. I restarted the computer but the Windows partition no longer shows up when I try to boot it, only Mac OSX and Recovery Disk. The Bootcamp drive is no longer accessable from System Preferences, and the Bootcamp partition folder is no longer accessable in the Devices area of Finder. Camptune no loner recognizes that there was a partition. Thus, I am no longer able to access the partition's contents or delete it and make a new one.
It would be preferable if I could fix the partition and have it accessable again, however I have no problem with deleting it and making a new partition. Any advice? Thanks for your time.
Here is the information from the Partition Inspector:

Bootcamp does show up in the disk utility but it is grey instead of black like the Macintosh HD.
The following information is available:
Mount Point: Not mounted
Format: Windows NT File System (NTFS)
Owners Enabled: -
Number of Folders: -
Capacity: 274.55 GB
Available: -
Used: -
Number of Files: -
What might be the best way to continue to repair it. I do not have the option to click on "verify disk permissions" or "Repair Disk Permissions".
Should I clone the hard drive in the target disk mode??
I'm not the best at this stuff so any more advice would be greatly appreciated!
Thanks! -
Boot Camp Partition no longer shows in StartUp Control Panel
My Boot Camp partition no longer shows in StartUp Control Panel, but does show up using Option Key at startup. This started soon after the latest Parallels update. The Boot Camp partition seems normal and healthy in the finder. Once started via the Option Key, Windows XP-SP3 runs fine. Upgrading to BC 3.0 did not have any affect.
I've tried LOTS of troubleshooting strategies, including completely deinstalling Parallels. Deleting obvious preferences, etc.. No joy.
Any suggestions?Hi,
if I remember correctly Parallels installs some kind of file system driver to OSX to access NTFS files system partitions.
The 'case of the missing Windows partition' is widely spread when using these NTFS file system drivers in OSX.
(Others are NTFS-3G; Paragons NTFS for Mac and Tuxera NTFS for Mac).
To my knowledge there is no other remedy to this phenomenon then to deinstall the NTFS drivers.
But as long as the Option-key is working maybe you can live with it.
Or use rEFIt http://refit.sourceforge.net/ as a Boot-Menu.

Windows 7 Bootcamp is no longer available in startup after updating to Yosemite 10.10
I updated my MacBook Pro (Retina, 15-inch, Late 2013) and then after updating I could no longer see my Windows 7 bootcamp when starting up. I followed this tutorial to try to get it too work again without losing any information: Windows 7 Removed after update Yosemite. I got to the part where we rebuild the MBR, but I got to part 8 and then it said that partition 4 is either too big or does not exist.
I do not know what to do from here and was wondering if I had done something wrong and/or what I can do to fix it?
Thanks in advanceYou seem to have found the correct partition. The following table has your values. (ASC thinks I have invalid characters in my table, so this is a screen shot of the MS Excel spreadsheet).
Leave your Testdisk display and start a new Terminal Window. You need to use the following steps. If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8.
Rebuild GPT4 using start/end offsets
Sudo gdisk /dev/rdisk0
P (print the full list of parts)
D (delete)
4 (part 4)
N (new part)
4 (part 4)
589682688 - Start offset in bytes (start point for Bootcamp part)
+387422201 - (Size offset as opposed to End offset)
0700 (Windows part type)
P (print list of all parts just to see what changes will be made)
W (Write the new GPT)
Y (Yes! really write the new GPT)
This will delete and re-write the GPT partition info for /dev/disk0s4.
Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 6. Accept all other defaults that Gdisk offers.
Sudo gdisk /dev/disk0
P (Print list of parts)
R (Recover)
H (chooses Hybrid)
Partitions numbers to be hybridized: 2 3 4
Y (Good for GRUB question)
N (part 2 boot flag)
N (part 3 boot flag)
Y (part 4 boot flag make NTFS bootable partition)
W (Write the new MBR)
Y (Yes! write the new MBR)
Reboot
Here is a sample Q and A for the second set of Gdisk steps.
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
Creating entry for GPT partition #2 (MBR partition #2)
Enter an MBR hex code (default AF): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #3 (MBR partition #3)
Enter an MBR hex code (default AB): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #4 (MBR partition #4)
Enter an MBR hex code (default 07): Press Enter/Return
Set the bootable flag? (Y/N): Y

Hello,
I'm trying to run Bootcamp on my 15" Macbook Pro (Maverick). I have 60 gig available on my computer's hard drive and have 250 gig on a separate hard drive that I have attached, which is single partitioned (MS-DOS FAT). It keeps saying "The startup disk does not have enough space, you must have 28 gig of free space available" Does anyone know what I'm doing wrong? Any help would be much appreciated.Thanks for the advice Bob The Fisherman. I'm just reading what turbostar has kindly written and it appears that perhaps, if I take advice from you both, I need to free more space up on the computer's hard drive?
With the external hard drive; would it be advisable to defragment? Know of any defrag freeware for Mac OSX?
Many thanks to you both. -
Windows Boot Camp partition not showing up on Startup Disk in Snow Leopard
Dear Fellow Mac Heads,
I have Windows 7 RTM installed as Boot Camp in one partition and Snow Leopard 10.6.1 installed in another. In Windows, the Boot Camp icon shows everything (i.e. Network, Windows 7, and Mac OSX Snow Leopard) so I can switch back and forth as I please. But in Mac OS, the Startup Disk menu under Systems Preferences only shows the Mac partition and Network. Windows 7 is nowhere to be found. I can't even do the OPTION on keyboard boot to get into Windows. I have to shutdown the machine, restart while holding onto OPTION key before all partitions show up. What's wrong with this picture? Is this happening to anyone else? Thanks in advance.Maybe you are using something like NTFS-3G?
Maybe this thread has something for you...
http://discussions.apple.com/thread.jspa?threadID=2146363&tstart=30
Oh, sorry I just noticed that you have read or posted in that thread, but didn't like the answer?
You get strange results with many 3rd party products. I don't use Bootcamp at all. Parallels 4 works very well with Snow Leopard and none of this booting back and forth hassle. Windows is just for research, use the Mac side for performance. -
Windows partition no longer bootable
Last night, I was using Bootcamp fine through VMware Fusion, no issue at all. I shut the VM down correctly and closed VMware.
Later that evening, I was trying to copy files onto my iPad through iTunes and got the warning that I didn't have permissions to view the contents of that file – I checked file info, I do, and also transferred the same file to my iPhone no more than 5 minutes prior.
Just in case, I booted into the recovery partition on 10.9.2 and ran permission and disk checks. When verifying the entire disk however, I got the error "The partition map needs to be repaired because there's a problem with the EFI system partition's file system".
A repair couldn't be done on the live disk so I booted back into OS X and created a recovery USB. From this, I ran the repairs to the entire disk, and repaired the permissions and disk for my Mac HD partition, and then checked the disk again in the recovery partition and whilst in OS X – the error is no longer registering.
From here – I no longer have access to Bootcamp (natively, or via VMware). The partition is mounting in Finder, and viewable in Disk Utility. It even appears in the "Startup Disk" pref pane, however, selecting the partition here just results in a blank screen on boot.
Before I booted into the recovery partition using the "alt" key, the Windows parition was there. Since that error, it's no longer available.
I've not resized the partition, nor have I changed any disk sizes.
I did, however, run the following commands following the iTunes issue in an attempt to correct:
sudo chmod a+rx /volumes/*
sudo chflags 0 /volumes/*
I understand I can probably remove the partition and start again, but that defeats the point. Surely there must be a fix through command line or something?
I'm not a computer novice, but this field is a whole new ballpark for me. I'm googling for answers, but they may as well be in another language – the common notions seem to be a broken GPT or MBR/GPT out of sync.
Below are the results of various terminal commands – maybe someone could analyze and point me in the right direction?
Kind regards and thanks in advance,
Jamie

Hard drive partitions are not showing in Startup DIsk
My hard drive is partitioned into two volumes. HD1 & HD2 (Both 500 MB)
I had Snow Leopard installed on one (HD2) and Mavericks istalled on the other.(HD1)
Both volumes were visible in the Startup Disk option in System Preferences and I could restart from either.
I upgraded the Mavericks istallation to Yosemite - worked OK.
System Disk option showed both HD1 & HD2
Restarted the Mac from HD2 in Snow Leopard mode - no probs.
Then the problem started. I wanted to restart from HD1 in Yosemite mode.
Went in System Preferences to Startup Disk option - HD1 did not show in the window - only HD2 (Snow Leopard) & Network Startup.
Any ideas anyone? (Could be a bug?)When I restarted using Com+Opt+P+R it went into Yosemite mode with both volumes showing in Startup disk.
Restarting with HD2 (Snow Leopard) gave me the same problem again. -
Partition does not show as startup disk
I have partitioned my iMac drive and have snow leopard on HD and Yosemite on HD2. When I go to change to the Yosemite partition (HD2) it does not show in systems available to startup from, even though it used to be there.
Mine doesn't either, or rarely (did in the past) so I just use Windows Boot Camp control panel where both do show up.
If you alter or resize or create a 3rd partition, that also can happen.
Some people use rEFIt boot manager, I never have and so can't comment on its utility, but might want to check it out. -
Resizing Windows Partition - No Longer Booting
Whenever I attempt to setup a Windows/Linux Dual boot I get hit with this same dilemma. I start off with a NTFS format partition with Windows XP on it. As soon as I resize the partition, it no longer boots. Even before installing linux/grub. I defragmented before attempting this, and I took every precaution. In the end, I'm never able to boot my Windows OS. I can boot Linux from the Grub menu, and I can still access my Windows files.
As of now I've reformatted back to Windows. I would just like to know what went wrong because I want to attempt another install later on.Ward,
windows is weird in that it notes somewhere the block numbers where the system is installed, and when that moves
it does not boot anymore.
Now you are making life more complicated then necessary: if you still have windows resized and installed (and not booting),
you can use the windows install cd and go into repair mode. It will fix the resized windows.
If you are starting from scratch, before installing windows, start a Linux live CD, do not install it, start the program
"gparted" and partition your disk as you want it. Then install windows in one of the partitions.
Instead of the Linux live CD you can also use a Gparted stand alone CD:

Hope it helps.

Moved my mac over to a new HD and my Windows Partition no longer boots.
Hello people smarter than me. I seek knowledge and skills I do not posses. I replaced my SSD with a bigger one going from 240gb to 960gb. The old one had two bootcamp OS partitions (Mac, Windows) and four partitions (EFI System Partition, Recovery HD make up the remaining two) I added a third (5th) partition that I labeled scratch (ExFat) that I intend to be a bulk storage for assets. Currently it will boot MacOS but not Windows 7.
My end goal is:

After HD change, Windows partition no longer boots up
Recently, I replaced my internal Hard drive on an early 2008 Macbook with a Solid State Drive. The original Hard drive had both an OS X partition and boot camp partition. I am currently using this drive as a external storage device (I did not delete anything, both partitions are still there with their respective operating systems) via a USB hard drive enclosure. Occasionally, I need to boot into Windows, but when I try to boot off the external drive, I get a black screen with a small blinking white line, and eventually, the error message that there is no bootable media. Please help!

Windows drive no longer available at power up with Option key?
I've done a byte to byte copy of a separate disk drive (320GB) that was my Vista x64 bootcamp drive. (In a MacPro) to a new 750GB drive. After I completed the copy process, I pulled out the 320GB drive and put in the 750GB drive. I hold down the "Option" key during power on and expected to see both my Mac drive and my Windows drive boot option. Unfortunately I only see the Mac now.
If I go into OSX I can see my Bootcamp drive on my desktop (Untitled), can open it and see that all my windows files are there. So what am I missing to get my bootcamp drive to show up during the power on Option process?
Thanks, Rob.RAID is destination for dmg image file.
But tried it again using a single Mac HD boot drive just to eliminate that possibility. Got the same error:

Windows XP no longer available?
I notice that Windows XP is no longer provided as an option when purchasing new thinkpads. So if I hate Vista, is doing a manual install of XP myself the only option that I have? Thanks.
Chaucerw, If your system came with Vista Business or Vista Ultimate, then you have downgrade rights to XP. You can always call Tech Support and order a set of XP Pro Recovery CD's. The CDs will restore your system back to an XP factory pre-load.
Please reference the Vista Downgrade page on the Support site.

Since I have downloaded IOS5 on my IPAD2 and synced to my IMac, Safari keeps dropping off before site is downloaded and is slow. There was an icon that showed how many windows were open on Safari and when pressed displayed them, that has disappeared and apps do not always download. Sometimes by making several/many attempts, it eventually downloads the website or app, but this is not right. When trying to dowload any lonks from an email, they simply do not open, it keeps going back to the home screen. Does anybody have any suggestions? I only bought the IPAD 2 in June!

Is it policy for Apple Store to ask for user password to repair iMac?
