Created partition after bootcamp windows install - 'No Disk'

Had Windows 7 installed via bootcamp for some time and decided to go back into the mac OS and create another NTFS partition for extra storage and here I am 10 minutes later finding out this destroys the bootcamp partition.

How Do I Add Partitions After Bootcamp Installation?

I want to have Windows 7 on my late 2013 Macbook Pro 13 to run applications not available on OSX. I need a small separate partition to store files for one of the applications that runs under Windows. On my older PC Windows machine I have C:\ that contains 98% of the data and a separate partition that acts as a separate drive (M:\) to store library files. This is a local copy of a server that I carry on my MBP, and doing this as I've done keeps the configuration files (that point to the server M:\) on my MBP consistent with desktop machines that actually point to a network shared drive (M:\). I just sync my small partition with the server every so often to keep my MBP functioning when I'm disconnected from the server. Now the problem. I can install Windows via bootcamp and that creates a C:\ (Windows partition) and gets Windows up and running. I have already learned the hard way about adjusting the partitions after bootcamp installation (I've rebuilt my Mac about 3 times ). I have been able to create the correct number of partitions by running the bootcamp assistant, creating the bootcamp partition, rebooting and <option> booting back to OSX, before installing Windows to add this 10GB partition (as FAT32) for my "M drive". Now after creating the "M drive" partition, I booted back into the Windows install disk (which has issues with USB drivers not functioning which I got past) and now I find out Windows will not install because it can't format the bootcamp partition since it will be a 5th primary partition and Windows 7 only supports 4 primary partitions on a drive. Is there a better way (without virtual OSs)?

Not possible. Boot Camp only works for two partitions - the OS X one and the Windows one. That's it. If you attempt to put a third partition on the drive, then Boot Camp is no longer able to manage the drive and you will lose the required boot loader for Windows. Getting things back to normal will then require repartitioning the drive back to one volume and reinstalling OS X from scratch.

Connecting to internet problems after Bootcamp Windows 7 install

I have just purchased a MacBook Pro, 13 inch, and have successfully used Bootcamp to install a partition, Windows 7, and the Windows support software. Problem is that Windows 7 is not detecting the WiFi video card and I cannot connect to the internet. I had downloaded the Windows support software directly from Apple in the Bootcamp forum. Apparently you can't do it using Bootcamp without the download hanging up. Is there an updated video driver I should be looking for? The MBP uses an onboard Intel video card.

The only source of the Bootcamp Support software is from within Bootcamp Assistant. Try again and be patient. The download servers are extremely slow.

Created partition without bootcamp, now i can't delete it

Hi Everyone,
I was trying to install Windows 8 on my Late 2011 MBP and it was not possible with Bootcamp. I tried it and got an interesting error like 'No bootable device...'. Then i decided to try to install Windows 8 without Bootcamp. Created a partition by Disk Utility on OS X, booted by Windows 8 Installer USB stick, deleted and formatted the partition by Windows 8 Installer. But still, i was not able to install Windows 8, don't know why.
Now, my problem is that i don't care about Windows 8 no more, i just want to merge the Mac partition and empty partition but i can't. In disk utility (in OS X), i don't see any allocated space, but if i boot by Windows 8 Installer, there are partitions or allocated spaces created by it and i can see all the partitions. I don't know what to do, how can i merge the partitions for using it in OS X? I think i need some serious help.
If there is nothing to do, i will create a backup of my files in an external drive and delete the internal drive. Will it work? But i don't want to do this since i have lots of files and my Mac uses usb 2.0 port.
P.S: I think it is not important but specifications of my Mac are:
Late 2011 MacBook Pro 15'', i7 2.4 GHz, AMD HD6770M 1 GB, 8 GB of RAM, Samsung EVO 840 120 GB SSD, Hitachi Travelstar 7k1000 1 TB HD, no optical drive.

Using Bootcamp Assistant re-arranges your partitions in a specific order, which is EFI/ESP, OSX, OSX Recovery HD, BC/Windows. If you do not use BCA to remove Windows but use Disk Utility to manipulate the BC/Windows partition, BC/Windows can be deleted, but Recovery HD will not let you merge disk space back into OSX partition. BCA while removing also rearranges Recovery HD to emerge the freed space back into your main OSX partition.
This is why it is recommended that DU should not be used to change partitions, if BCA is also used.
BCA creates a Hybrid MBR, while a straight W8 installer uses EFI to boot on 2013+ Macs, but prior Macs, like the 2011 MBPs do not fully support W8 direct installation.
In either case, as tbirdvet suggests, the recourse now is to back up, use Internet Recovery (Command+Opt+R - you must see a spinning globe), erase your internal disk, and restore from backup.
Please also see OS X: About OS X Recovery - Apple Support.
Thanks, i think it seems like this is the only solution, luckily, since the system is on the ssd i don't have to reinstall the OS. Now i am creating a backup then i will erase the disk and load my backup.
Since you have two physical drives, being treated as two separate disks, depending on which disk you were manipulating for Windows, you may have to erase one or both drives.
If the second disk (HDD) was your Windows destination, and you removed the original built-in Optical drive, BCA set the system to boot from the unavailable Optical drive which resulted in 'No bootable device' error.

Stuck in Bootcamp Windows install and can't get out

late 2009 iMac with Mavericks with homemade fusion drive with super drive removed.
Was working fine until i tried to use bootcamp to install Windows 7. Now I'm stuck in the Windows partition, windows won't install and can't get out of the loop. Machine boots white screen with no apple logo and chimes. Eventually has black screen with No bootabe device -- insert boot disk and press any key. I have a USB drive. I've tried everything. Doesn't seem to be recognizing bluetooth keyboard. No sort of button combination on startup works. Tried holding X, command-alt PR, shift, command-R, option. Tried everything. Light doesn't come on on keyboard in startup which means it's probably not recognized. Tried disconnecting internal drives and booting from USB. Tried booting from Time Machine USB drive. Nothings works. Think a USB keyboard would solves this?

I have gotten in this loop. When doing this kind of thing, a usb keyboard would be good to have around, and that is probably the problem, because when I would boot, the first time set the windows partition to the default drive. Hold the key combo and boot into OSX, and go into Settings/Startup Disk/ and change it to The osx hd.

Unable to Adjust Partition after BootCamp

Hi
I use Boot Camp Assistant (BCA) to remove Windows 7 and ended with a message "Your disk could not be restored to a single partition". I am not sure if the Windows 7 is successfully removed.
I use Disk Utility (DU) to try to "re-partition" the Mac HD to 250GB (from 218GB) but after checking catalog file and other processes, it ended with a message "Could't modify partition map because the file system verification failed"
I use the First Aid to verify disk and reported the partition map appears to be ok
I use the Repair Disk and it reported the partition map appears to be ok
Below is the map of the partition after I remove the Windows 7. I dragged the white color region (botton right) to extend to 250GB and click Apply and failed with the error message "Could't modify partition map because the file system verification failed"

So just clone the volume and then erase and restore.
If you created Windows with BCA and you didn't do anything else in Windows or Mac OS to add change or shrink etc BCA should have.
In some cases that error happens when creating or attempting to create Windows partition not on removal.
Paragon CampTune is handy but for what you want just use Carbon Copy Cloner.
I always advise using a dedicated drive just for Windows.

Cant create partition for bootcamp

I open up Boot Camp Assistant, select Install Windows 7 then i divide my windows partition to 350 GB and click Install with the Windows 7 disk inserted... but it still says wait for the disk to be recognised and doesnt go through...
If i remember correctly, on Snow Leopard it was first creating the partition and then it was working perfectly...
Any clues?

Are you referring to the Windows disc Boot Camp isn't recognising? Perhaps try putting the disc back in the disc drive and then try opening Boot Camp Assistant and continue with the installation of Windows through the Boot Camp Assistant. In order to install Windows, the Boot Camp Assistant would ask you how much space you wish to allocate to the Windows install (for you to use once Windows is fully installed). If you set "divide equally" it would shrink the existing Mac OS X partition of the hard drive and create a new partition on the extra space that would then be available to use, which it would create a Windows-compatible partition for Windows to use. So 2 partitions would be on the hard drive now. So when you launch Boot Camp again, you can go to the "Install Windows 7" option straight away, as I'm presuming Boot Camp already created the separate Windows-compatible partition on the hard drive.

*Problems uninstalling itunes/quicktime after using windows install cleanup

I was having problems installing itunes/quicktime 7.6. Everytime I tried to install it it would say that it does not have a valid digital signiture. So one of the suggestions I saw on this forum was to install windows install cleanup and use it on itunes and quicktime. So I did but all it did is mess up my old itunes/quicktime. Now when I go to try and uninstall itunes and quicktime from the add and remove programs in the control pannel it does not even show itunes or quicktime in my program list. Any suggestions??

Ok, Update. I was able to remove itunes and quicktime manually after going into my windows task manager and to the processes tab and ended all processes involving itunes, apple, or quicktime. So now when I install itunes/quicktimes via apples site when it gets to the end it just disapears and nothing happens. I searched to see if it installed anything and it didn't, didn't even give me any reasons why. Can anyone help me with this?? It would help me a ton!

Lost Linksys password after new windows install

I have had my Linksys E4200 for a few years now. When I'm home my cell phone and laptop both use my wireless connection. My desktop computer had the main Cisco console which provided the passwords to both my cell and laptop.
My problem is I recently had a virus attack to my desktop from clicking on a bad email link. I couldn't remove the virus so I did a clean windows install. I can't find my Linksys router box but I found my CD disc. The disc is asking for my password which is probably somewhere in my original box (which of course I can't find now). My router has the model number and mac address but I don't know how to reinstall my console without my original password.
I never disconnected my router when I did my new windows install on my desktop, and my computer still recognizes my Linksys router. When I click on the device icon it says, "network connected", Catagory: wireless network router, Manufacturer: Cisco, Model: Internet Access Server. Is there enough information so I can recover my password and install my console again? Thanks...
Solved!
Go to Solution.

Hello DuMartin,
It is asking for the password you set up for your network. If that will not work, then it would be best to reset and configure the router again.

Y40 GPU not working after clean windows install.

I did a clean Windows install since I got a new HDD and I can not get the switchable GPU working again. I have the latest intel and amd drivers from Lenovo installed and both show up under dxdiag. When I try to access switchable graphics settings all I get is a blank page. The game I am playing shows what gpu is being used and it is Intel.
If anyone has any ideas that would be great!
Thank you!

Created second partition in bootcamp Windows and converted whole disk from basic to dynamic

Hi everyone. I don't post here often however I hope the following helps someone else down the road.
I currently user ML and have bootcamp installed. I needed more space on my ML partition so decided to free up space from bootcamp. Going about this completely the wrong way I booted into my bootcamp partition, ran the computer management app and shrank my boot camp partition by 8 GB. This created free unused space which I decided to format over to NTFS with a view to booting back into ML, deleting and adding to my ML partition (how wrong was I).
Prior to completing the format of the newly created free space in bootcamp I was presented with the usual 'yes' / 'no' warning dialogue saying something along the lines of 'formatting this disk from basic to dynamic will prevent any installed operating systems from booting'. I made three monumental blunders at this stage: a) not reading the dialoge box b) completely disregarding the severity of the warning in the diaglogue box c) (you guessed it) pressing 'yes'.
The moment I pressed yes it was the start of a four hour feeling of grief as I thought of the last 6 years of my life wiped from below my nose with no time machine backup.
Upon rebooting bootcamp to get into ML the reality of the situation hit home as no OSX boot, no apple logo, no boot sound, my mac is trying to boot into windows without the option key being held in or warning to present me with a BSOD.
One thought in my mind: "oh Sh*t!!!"
3.5 hours passes and much reading online, learning of linux commands, downloading of linux distros, finding out how to install software and successfully setup a bootable linux usb and I'm typing this up on my mac while I time machine my data away to a freshly formatted external drive. Many lessons learned.
This is what I did amongst the vacating of my bowels and absorption of much nicotine.
There are two pointers to this guide. I was lucky enough to have another computer at hand to conduct the research and create a bootable usb. It a windows 7 toshiba z930. So you're going to need at a minimum: another computer (windows for the guide), a usb stick 2~4GB should be ok.
1) download a linux iso, I downloaded ubuntu, you can download what ever you like, but you're going to need linux (the rest of my mini guide will use ubuntu 13.10 during examples) http://www.ubuntu.com/start-download?distro=desktop&bits=64&release=latest
2) download Universal USB Stick Installer 1.9.5.1 (from now on as UUSI) http://www.pendrivelinux.com/downloads/Universal-USB-Installer/Universal-USB-Ins taller-1.9.5.1.exe
3) plug in your usb drive. make sure there is nothing on it that you need to keep as it will be formatted and lost. also plug your mac into a router connected to the internet. this will help prevent any issues with wireless drivers when booting into ubuntu later on.
4) once the downloads are complete, run UUSI, get past the prompts until you get to the 'setup your selections page'
5) (A) select 'ubuntu' from step 1. (B) browse to your freshly downloaded ubuntu iso in step 2. (C) tick show all drives. (D) select the drive letter of your usb in step 3. tick we will format *drive letter here*. (E) depending on the size of your usb set some persistent storage - I had an 8gb usb to hand so I set 1GB, less will probably do. (F) double check your settings and click create then let the program do it's thing, it can take some time depending on the speed of your usb drive, mine took 10 mins.
6) safely remove the usb and plug it into your mac, turn the mac on and hold the option key, once the usb drive is found hit enter and select ‘try ubuntu without installing’
7) wait for the ubuntu os to load and click the settings icon from the left tool bar
8) under settings click user accounts
9) click the + symbol in the bottom left hand corner
10) select administrator from the account type box and type a name for your account then click add
11) select the account and change the password, then confirm it and click change
12) go back to the desktop and select the power off symbol in the top right hand corner and select your name from the list, this will log you out of your current session and ask you to log in under your newly created login
13) once logged in click the settings icon again from the left hand menu and under settings go to software and updates
14) in software & updates under the ubuntu software tab tick ‘community maintained free and open source software (universe)’ and ‘software restricted by copyright or legal issues (maintained)’ then click close and close the settings window. Also check at the bottom of this window under ‘installable from cd-rom/dvd’ for two entries ‘cdrom with ubuntu 13.10 ‘saucy salamander’ - uncheck on of these entries if both are the same. Not sure if this was just me or a common problem. I found that trying to do the apt-get update would run into errors at the end if one of the entries wasn't deselected.
15) hold ctrl + alt + T to bring up the terminal
16) in the terminal window type sudo passwd root then enter a password for the account
17) in the same terminal window type sudo -i and enter the password given from step 16 if requested
18) in the same terminal window type apt-get update and wait for the update to finish without errors
19) in the same terminal windows type apt-get install testdisk and wait for the installation to finish without errors
20) in the same terminal window type testdisk
21) select create log and then the drive you want to work on e.g. your main apple OS hard disk then select proceed
22) select your file system type - for my ML installation I had to select ‘EFI GPT’ I don’t know if this will be the same throughout all macs / macbooks
23) select analyse, the step should take less than a few seconds and testdisk may report back errors with the partitions or it may proceed to the ‘current partition structure’ screen. If errors are displayed proceed past them until the next screen.
24) at the ‘current partition screen’ select quick search, you will have an opportunity to backup your drive here. I won’t go through this step (never learn) as I did not complete it myself
25) after the searching has completed all the partitions on the disk should be shown. Find your OSX partition using the size reference at the bottom by pressing the up and down keys. Once you have found the partition that relates to the OSX partition that is failing to start hit the right key to make it a primary partition a ‘P’ should show to the left of the partition data. I had to make sure my EFI System and Mac HFS (155GB) partitions were marked as primary.
26) hit the enter key to continue to the next screen and use the right arrow key to select ‘write’
27) the program will warn you it will write the partition table so hit ‘Y’ and a confirmation should be displayed that this has been successful.
28) reboot the computer and remove the USB stick (i removed it at the white loading screen after the reboot, not sure if it makes any difference)
29) allow the computer longer to boot, mine took about 35 seconds to show the apple symbol whereas it normally took between 3~7 seconds before I destroyed it.
30) get into OSX and backup everything to time machine or whatever you use then it probably a good idea to kill off your bootcamp install and refresh your mac from the fresh backup.
Hope this helps someone. I couldn’t find anything conclusive on the net when I ran into problems (all my own fault really for not reading the dialogues correctly) however I used bits from multiple forums and found out parts myself especially the linux parts as I don't know the os at all . Certainly won’t be making this mistake again anytime soon.
Well I’ve had an awful night and have work in two hours but at least the last 6 years of my (now backed up) life is intact and in my hands. I’d rather lose a night of sleep than lose all my data.
Sorry if some of the stuff above is wrong as I don't do this thing on osx / linux at all really. At least it might point you in the right direction.

29) allow the computer longer to boot, mine took about 35 seconds to show the apple symbol whereas it normally took between 3~7 seconds before I destroyed it.
30) get into OSX and backup everything to time machine or whatever you use then it probably a good idea to kill off your bootcamp install and refresh your mac from the fresh backup.
Hope this helps someone. I couldn’t find anything conclusive on the net when I ran into problems (all my own fault really for not reading the dialogues correctly) however I used bits from multiple forums and found out parts myself especially the linux parts as I don't know the os at all . Certainly won’t be making this mistake again anytime soon.
Well I’ve had an awful night and have work in two hours but at least the last 6 years of my (now backed up) life is intact and in my hands. I’d rather lose a night of sleep than lose all my data.
Sorry if some of the stuff above is wrong as I don't do this thing on osx / linux at all really. At least it might point you in the right direction.

Problems booting a Windows partition after failing to install and uninstall NTFS 3G

Hi,
I run Windows on my Mac and I installed MacFuse and NTFS 3g today to see how would they work together. It was a terrible decission...!! After restarting the computer a window popped in the desktop with the following message:
NTFS-3G could not mount /dev/disk0s5
at /Volumes/BOOTCAMP because the following problem occurred:
Did not receive a signal within 15.000000 seconds. Exiting...
Afterwards I uninstalled NTFS 3g from System Panel but had problems uninstalling MacFuse. Curiously, I didn't find any preferences file of any of them. Anyways, I dived in some forums and about diferent ways to tackle this, of which I followed this one by bredikhin:
Link: https://discussions.apple.com/thread/3942492?start=0&tstart=0
This succeeded in unistalling MacFuse, but didn't allow me to boot Windows at the menu you arrive after pressing and holding the option key. Nonetheless, I can read the files in the Bootcamp partition from Mac.
I'm using a MacBook Pro running OSX 10.8.4 on a 2.3Ghz Intel Core i7 processor with 4GB of memory
Thanks in advance!

As has been said, Windows 8.1 isn't formally supported yet, though I have it installed on mine.
Sadly many people have had problems with Bootcamp on Mavericks, especially on later Macs.
Some have had success by creating the bootcamp partition with Bootcam Assistant then rebooting in to OSX and deleting that partition then creating a new exFat partition in its place, named BOOTCAMP.
That partition can then be re-formatted NTFS by the Windows installer which then makes it usable.
Others have been less successful.
If all fails Google can turn up various workarounds until Bootcamp/Mavericks get sorted out (and 8.1 becomes supported).

Increase Mac partition after shrink Windows bootcamp partition

I have a Mid 2010 Macbook Pro running Mac OS X 10.9.4 with a 500GB HD.
The HD is partitioned with 370 GB to Mac and 128 GB to Windows and I decided to shrink the Windows partition to 65 GB because I needed more space on Mac, and I barely use Windows.
I resized the Windows Partition using Mini Tool Partition Wizard and moved it to the end of the disk, leaving the empty right after Mac partition.
I'm able to boot Windows partition and use it normally. The Windows C: disk now has 65 GB.
When I boot on Mac OS X and try to use disk utility to increase the Mac partition, it says that the Windows partition still has 128 GB.
It is possible to use the empty space I created?
Here's some information about my partitions:

Plz help i really tired from searching creat MBR partition without bootcamp or install win7 in GPT guid

hello i have more than one partition on my macbook pro mid 2012 13 inch and its impossible to me to make it one partition for some reasons one of them that the partition sys is the second any way i tried to creart partition EXFAT and tried to install win7 but it says that can't be installed in GPT guid i talked chat with apple more than one 9 times to find answer but it's useless i get pro solution here

The TechRecipe article is old. Some of the commands still apply, but it is a very custom solution.
Yes, there is a way to create a custom hybrid MBR to accommodate additional partitions.
1. This is a very fragile arrangement, and any Apple Software upgrade can break it.
2. Any Hybrid MBR changes require this process to be repeated every time it breaks, which you should be willing to undertake.
3. If you want to do this, and maintain it, please post the output of the following commands from OS X Terminal?
     diskutil list
     diskutil cs list
     sudo gpt -vv -r show /dev/disk0
     sudo fdisk /dev/disk0
4. Sudo command require your password, which is not echoed back to you. You may also see a warning about improper use of sudo and potential data loss.
5. Can you describe what exactly are you trying to establish?
6. You previous attempt with exFAT failed, because your Mac requires a Hybrid MBR which maps the GPT to a MBR using a one-to-one mapping.
7. If you just want to run OS X and Windows, and do not want to run any custom disk partitions, you should use Bootcamp Assistant. If it is failing, it can be addressed.
