Missing operating system of DM4

• "Missing operating system" is displayed when you try to start Windows 10

  I have been using bootcamp to access the 10 Windows for quite awhile. It was working perfectly until a member of the family installed a Windows Update, but the battery is dead during the update. Following this window would charge any. A black screen with a blinking cursor. After that, I went back on fairing and wrong used the partition synchronization tool. Now, Windows is in a worse state and the "Missing operating system" message when you try to get back in. In addition, the Mac startup disk no longer allows me to reboot the laptop using the bootcamp partition, as if the partition is not more detected. Disk utility simply shows a greyed out "Disk0s4."

  I spent a lot of time looking for a solution, but without success. Here are some of the things I've tried so far:

  I don't know if its of any importance but sudo fdisk e/dev/disk0 the following message is displayed:

  #: cyl hd s - cyl hd s id [Start - size]

  I also tried to use Windows, but without success startup repair.

  If there is no solution to this problem, all least, hope to be able to back up everything that was on the Windows partition.

  Thank you very much

• Error "Missing Operating System".

  Hi all. I'm trying to dual boot a 2013 end macbook pro with windows 10 and el capitan. I need to be able to run windows 10 to use some programs required by my University. I was actually able to configure my computer completely, so that it works on both partitions perfectly, but in a few days the windows partition seems to fail. This has happened three times now, and with each failure, I completely deleted the partition and started from scratch. The error I get seems to be completely random and occurs when I turned off my computer, turn it on and try to start the "Windows" partition It reads "_ Missing Operating System".

  To install Windows 10 first, I used the boot camp assistant tool to make a partition of 100 GB out of my 500 GB drive. I went through the process of boot camp and created a bootable usb key from the iso image windows 10. I booted from the USB and windows installed and everything worked perfectly. I had to delete the partition generated by the wizard boot camp and create a new space on my disk unallocated hard usb Boot because it would not me to install windows on the partition as boot camp originally created. I installed all the drivers through bootcamp tool which displayed once windows 10 has been installed and all was good. I did all the updates of Windows 10 through the parameters, and then I did all the app store updates. I installed applications base approximately 4; This includes chrome, iTunes and uTorrent.

  There seems to be no problem with my el capitan score whatsoever, and I was totally unable to find anything on the internet to help me with this problem. I chatted with support of microsoft and apple support. I was told that "it seems that the operating system on the Windows side is having a problem remaining installation and which is the origin of the problem" apple support. I was also told by microsoft that "maybe microsoft and apple cannot work together in a single machine :-) ».

  Any help at this point would be greatly appreciated. Thank you.

  Well, in the best case, you will need to reinstall the system.

  Hi, well seems I'm having an affair with the toshiba.

  Had to uninstall and reinstall the drivers for the touchpad on/off function - view still does not.

  -turn off the laptop.
  -turn on computer laptop while holding the key '0' (next to the key 9)

  No recovery disc were in the area when buying this new laptop in June 2011.
  Seems I have ongoing issues with the functions of the key board.

  It was the same problem, I have lived 2-3 weeks ago and said it was a virus and had to correct this through the clearing system and reinstalling from a backup.

  > No recovery disc were in the area when buying this new laptop in June 2011.
  The recovery CD were not part of the package, because you can create a clean recovery using the recovery disk creator.

  Here is a FAQ How to run the system on Toshiba restore Australian books:

  If the HARD drive recovery is not possible, then you will need to use a recovery disc.

  > I have a lot of data and images on the disc that I didn't lose

  I have bad news boyfriend. The message missing operating system means that the laptop can not find the operating system on the HARD drive. And do you know why the laptop can not find the OS (operating system)?
  Because the HARD drive is DEAD!

  I had the same behavior, 2 years ago. My 4 year old HARD drive was dead. It was an accident of the head and I lost all my files :(

  But fortunately, I created backups on CD so I could restore my photos and my mp3.

• Missing operating systems after trying to install Ubuntu

  I have a dv6 7010 WE

  I used to have Windows 7 x 64. I tried to install a dual boot Ubuntu, but if it worked I would not write this.

  I tried to install Ubuntu with a live CD. I've been running Ubuntu, I thought it was over install and I restarted the computer. When he came back he said "Missing Operating System". The live CD was not in when he did this, and then I put it back on and restarted and he returned to Ubuntu and offered to install again. I didn't install it and I restarted just once again (error). Yet once he came with "Missing Operating System". I restarted again, but press the ESC key and went to the start menu. I've sailed around, trying to make a boot recovery and try to do a system restore, but none of them worked.

  Now when I put the Ubuntu CD in I don't you Ubuntu, but the same screen lack of operating system

  I tried to get a download of Windows 7 and reinstall it on another drive, but I didn't do well do things and don't want to take the risk even once.

  I cannot enter in a command window and can do stuff with it, but I have no idea what to do at this point.

  I'm stuck and I really really need help. I really really want to buy a new computer. My computer did not come with a Windows 7 installation disc.

  Help please.

  Please do not answer. I just ordered recovery through Staples discs.

  To anyone else reading this, I suggest you just buy the recovery disc for your computer.

  The recovery discs also got rid of all the stuff of Ubuntu

  When my PC running Windows 7 - the external hard drive is connected and works fine - but when I close and come to restart I get message "Missing Operating System". One point to mention is that I renamed E to G external drive letter. If I unplug the USB hard disk, start works fine and I can plug back into the external hard drive without any problem. Someone at - it ideas on how to fix this please? Thank you.

  Hello

  Go into your BIOS and change the boot order.

  It tries to Boot from your external hard drive when you receive this message.

  Do the internal hard drive first in the boot order or disable USB compatible with the start (or similar words for USB devices).

• Satellite A200 starts with the message "missing operating system".

  IM wondering if anyone can help... I have a Toshiba Satellite A200, who, at the start, just comes up with a black screen and the "system of missing operating" in the upper left corner.
