• Unable to overcome error - "the startup disk cannot be partitioned or restored to a single partition.

  Hello!

  I'm trying to install Windows on my iMac (late 2013, running 10.11.6) without success.  I created the ISO to a flash drive, but when I try to use the Assistant Boot camp, I am referred to the following screen:

  

  I did my best to study solutions. The cause, by apple support discussions, is that there is another partition of pre-empting (stop) the wizard boot camp partitioning the hard drive.  I studied the partitions on my HDD after unplugging all devices and found this:

  

  This shows the main partition: Macintosh HD, the bootcamp partition: BOOTCAMP; and 2 unknown partitions: "Apple HDD ST100DM003 Media" and the same * M004.  I was able to delete the first Apple ST100DM003 HARD disk partition and ran first aid on the fusion drive after that the second he would not remove.  Also, I can't delete the boot camp partition.  I keep getting the same message when I try to install windows on a partition of the fuser unit using Boot Camp Assistant - "Startup disk cannot be partitioned or restored to a single partition".

  Any suggestions?

  Please after the release of the following OSX Terminal commands.

  A few months ago, I created a Windows 8 bootcamp partition, and then, I updated for Windows 10 without any problem. But I no longer need and I would attribute this space to OS X.

• the startup disk cannot be partitioned USING BC

  So basically I can't remove my HD BOOTCAMP volume, and I can even boot from it. I tried first aid and formatting to different formats then put in shape in the journal. I don't want to lose my space and prefer not to reset my macbook. It doesn't recognize it as a bootable disk.

  You can remove only using the Boot Camp Assistant. The volume is not bootable until you install Windows on it.

  If you cannot delete the partition with the BCA, then you will need to repartition the disk. Don't forget to make a backup because Re-partitioning will wipe everything.

• Boot Camp - boot disk cannot be partitioned or restored to a single partition

  Hello

  Would really appreciate some help on this!

  I tried to install Windows 7 on my iMac 2015 but during the installation of windows it guests that the partition must be formatted in a different way.

  Now when I try to use Boot Camp once again, I get this message:

  The startup disk cannot be partitioned or restored to a single partition.

  The startup disk must be formatted in a single volume in Mac OS extended (journaled) or already partitioned by Boot Camp Assistant to install Windows.

  The problem is that I can't erase the Boot Camp Partition in any way using disk utility.

  The Macs listed to install Windows 7 and previous versions on your Mac with Boot Camp - Apple supported support W7. 2015 macs don't support W7.

  The only supported method to remove Windows from a Fusion using Mac drive is Boot Camp: Remove Windows from your Mac . Do not use disk utility.

  You seem to have tried a deletion of THE (not deleting a partition), at least once. Your BC partition is now a HFS partition. Convert it back into a FAT32 partition on THE and then try to remove it by using the link provided.

  If you are unable to remove using BCA, then use the steps of the Re: doesn't have windows via bootcamp 8.1 installation .

• BootCamp not appearing player is not in the startup disk.

  Just today, I noticed that my bootcamp drive does not appear in the startup disk in system preferences. I use 10.11 El Capitan. However, I was able to boot both of the OS by pressing 'option '. And also disk utility does not show the bootcamp partition. But in the finder, it shows the partition. When I try in recovery mode disk utility, here it shows the bootcamp partition. But not in OS X.

  And finally, 'get info' when I try and guess what: it shows the last open: January 1, 1970, at 05:30. which is never true.

  Is this problem of OS X, how do I do?

  

  You can try to run first aid by using disk utility. I would start on the recovery drive to do.

  Restart the computer and hold command-R

  Also, once you have repaired the disk in the recovery drive, quit disk utility, then leave OS X Utilities and select "Choose Startup disk." See if the Windows partition appears here.

  Good luck

• Need help with the disks 'unreadable' configuring software raid after the death of the startup disk and system restored.

  I'm looking for some advice on how to restore a windows xp installation software raid 5 that was running on my XP system. I had a problem when the startup disk has failed, but I was able to backup the system before it can. I replaced the drive and restored the system and everything came, but I was not smart to do this and accidently left the readers connected when restoring raid. I don't know if windows has done something when I tried to install XP on the new drive, or maybe something else has happened when I restored the system from the backup, but my raid drives can not be used. There was a moment in the restaurant business I saw a message on the MBR, but I thought that was just for the drive being restored. I didn't have a single player who held any information on the other disks in the system, but I'm not 100% sure on that.

  When the system boots the windows logo screen takes 10-20 minutes before you get on the desktop. Windows Disk Manager takes 20-30 minutes to fill the list of drives and status on the disks three raid is 'dynamic' and 'unreadable' is not reassuring. I suspect it's a problem MBR or partition table that must be corrected before trying to reactive the raid, but this is just speculation.

  The raid drives are on a promise ide/scsi disk and make it appear to start correctly with names and sizes. After that I get nothing. I do not have another scsi controller (or), but I thought I'd try active @ partition recovery to see if she can find information on the disks.

  I hope someone has some experience with recovery like this, because this is a first for me. I thought I was pretty sure running a raid-5, but wouldn't you know, the tech gods have found a way to crush my plans...

  Thanks in advance for any help!

  I have recived portable computer of the Government with windows pre installed 7professional but now I want to format and reinstal it I require the startup disk and product key (my OS is authentic)

  If it's a copy of volume license installed, you will need to contact your employer to find the product key and get the installation files.

  If it is preinstalled at the factory with Windows 7 Professional, then use the recovery partition to reinstall Windows 7.

  New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

  This is how the recovery partition is accessible to most popular brands...

  For Dell, press CTRL + F11 directly after switching on the device

  For HP, press F11 directly after switching on the device

  For LG, press F11 directly after switching on the device

  For Toshiba, press and hold "0" BEFORE and during the power upward

  For Acer, press and hold ALT + F10, as soon as you see the logo

  For Asus, press F9, as soon as you see the Asus logo.

  For Samsung, press F4 to the power upward...

  For Fujitsu, press the F8 key directly after the power

  Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

  Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".
