I accidentally deleted my boot partition

I tried to install Windows 10 using Bootcamp but it failed and I had to start. I thought I had deleted the Bootcamp partition, but I accidentally deleted the main boot partition for Mac OS. When I try to start my Mac Apple logo appears for a while, then finally I do not see an entry sign.

In an attempt to solve this problem, I started my Mac upward into recovery mode and reinstalled Mac OS on the partition that I created for the thought of Windows, I would be able to access my files and pass them to the new facility. Mac OS installed fine, but I now have a 800 GB partition, I can't access. He appears in disk utility, but I can not unlock or fix it.

Question is, can I repair the boot partition and to come back to how I was before I screwed up?

Or, is it possible to unlock the main so partition that I can access it from the new installation, back up everything can start all over again?

What do you backup before you start this project?

  • Satellite A665 - accidentally deleted my recovery partition

    I accidentally deleted my partition restoration for TOSHIBA SATELLITE A665 LAPTOP.
    Would I be able to create a partition for recovery with the same content again?
    If so, how?... really confused...

    Should I buy a new recovery disk because when I bought my laptop I did not receive any recovery disk...
    I'll be able to get my laptop as it was before?

    Hello

    Do not have recovery disks because there is a pre-installed software called Toshiba Recovery Media Creator who creates these discs.
    But it must be created in the first day of the purchase, I assume that you will not be able to create this disc now because the partition (which contains the image files) has been removed.
    So now, you will need to purchase the recovery (about 30) disk in order to recover the laptop. After that the recovery partition should be available again.

  • Z420: accidentally deleted the recovery partition

    Accidentally deleted the Partition D:Recovery on my win machine 7 Z420. I have HP recovery disks: System Recovery, Driver Recovery DVD, 8.1Pro operating system and operating system Win 7 pro sp1.  The use of these will recreate the partition D automatically or do I have to do this first.  I have the orientations of the white paper "Restoring Microsoft windows 7 on the z420 ', but I was told that it will not recreate the recovery partition.  There is no need to restore everything if in fact I still have until the end without disk recovery D and files?

    There is no way to recreate the recovery partition on the z420.  The recovery disk media that I bought with the Z420 does not include this information.  It will only recover the original operating system and drivers and software that came with the system.  I spoke with HP z workstation support today.

  • When I installed 10 windows on my mac, I accidentally deleted the MacOS Partition. I made a new D: drive partition in Windows 10, but when I go to the restoration of the internet and try reinstalling Mac, it says that the disk is locked. How to unlock thi

    So basically, I downloaded the ISO of Windows 10 file and installed using boot camp. During installation, I accidentally formatted the Mac OS partition and replaced with the windows one. Now, I'm trying to reinstall Mac OS using the internet retrieval feature. I partitioned a new D: drive named OSX, and there is no data on the disk. I then click on reinstall Mac OS. I try to select the disc of OSX I partitioned, but it says that the disk is locked. Anyone know how to unlock the drive or should I do something else?

    Thank you very much

    CJ

    I think one of the problems might be that my Windows partition has replaced the C: drive where was the OSX partition. I tried to move the Windows operating system on a drive b or e :), but it won't let me. Let me know if this could be a problem too.

  • I accidentally deleted the boot.ini file, and my system is not booting.

    When I switched on my system, "NTLDR is missing. Press Ctrl + Alt + Delete to restart your computer"appears. How do I include this boot.ini file in my system. The only splash screen appears. !!

    The choice is yours. If you have a Windows install disk, you can try to boot from it and go to the recovery console according to the instructions.  Most of the OEM machines these days above do not come with installation disks, in which case you will need to find another way to boot your machine from a CD.  If this seems difficult, that there is nothing wrong with she participates and have fixed it.

    You burn your set of recovery disks? If so start from the first person to reinstall. If you burn a set you can order one from your page of software and drivers:

    I checked your model here at HP support page and nothing is more than a disc of recovery indicated as being available. Are you sure that you burn & maybe set aside recovery when you got the machine as you normally have been asked to do?

    If this is not the case, they are available here for $27:

  • After removing the Dual Boot, I can't delete the old partition

    Some time ago I installed an SSD and I have Windows 7 installed in Dual Boot with the Windows 7 system.
    So, I had two versions of Windows 7, which worked well.

    Now I no longer use the old system, I disabled the function of Dual Boot. I want to format the old drive, but it does not work because Windows still sees it as active system partition. In addition, I can't delete the partition.

    How can I format or delete the old partition?

    I already tried Msconfig, Bud that did not help. Default Msconfig begins with 'selective startup' and an operating system that is displayed in the Startup tab. When I select 'Normal Startup' there are two operating systems that are listed in the Startup tab. When I delete the old and reboot, it is back again...

    Who has the solution?

    (1) create a system repair disc (if you do not have an installation disk for Windows 7 for the version of Windows you have installed).
    http://Windows.Microsoft.com/en-us/Windows7/create-a-system-repair-disc

    (2) then remove the hard disk you want to format. Now try to start the remaining version of Windows. You should see a missing bootmgr message. Proceed to step #3.

    (3) Bootmgr is missing, message or black screen with cursor flashing
    (See method #2 in this Wiki article)
    http://answers.Microsoft.com/en-us/Windows/wiki/Windows_7-system/Bootmgr-is-missing-message-or-black-screen-with/73fef5b7-5a7f-4910-a2b0-7219e9ec1646

    (4) after you have created the BCD store on the remaining drive (to step #3 above), it should start up on Windows and also be the partition 'Active'.

    (5) shut down the PC and set the old drive, turn on a load Windows and then delete all the remaining partitions on the old disk.

    Do a clean install:

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  • Deleted the two Partitions during the Installation of Windows 7

    Hello, I accidentally deleted the partition of drive 0 2 on stage 13 on the link I posted below, when I actually had to format Disk 0 partition 2. How can I get that back now, I have more readers. Is there a way I can recover my partition?

    The installer should automatically re-create both, one a partition recovery and the other partition system where Windows is stored.

    Boot from the Windows 7 DVD

    Click Install now

    Accept the license agreement

    When the option is displayed to select a type of installation, click (Custom advanced)

    Click on drive Options

    Select the disc/s click on Delete

    Click new

    Click on apply

    Click OK

    Click Format, and then click next to proceed with the installation

    My records were recovered after the restart of the Computer.Thanks anyway

  • Vista cannot start because of accidentally deleted system files

    Hello

    my laptop was working very well until some files were accidentally deleted and now Vista cannot start.
    There is a message saying that I need to contact the system administrator or the manufacturer of the pc.

    Is there anything you could recommend?
    I would appreciate if you could help me find a way to record all of the information contained in hard drives.

    see you soon

    If you are not able to boot up the laptop and refuse it to Vista to start then take recovery in hand, insert it and start on this CD from Toshiba.

    Then the cell phone should boot from the recovery CD and reinstall the whole OS again.
    This should help, but the HARD drive will be formatted.

    Hello

    You can download the Setup from the Microsoft page of WIindows disk:
    http://support.Microsoft.com/kb/310994/

    Then you could install the Microsoft recovery console that helps you use the commands * Fixmbr and Fixboot * to fix the Boot Manager:
    http://support.Microsoft.com/kb/307654/

    I think this should help other rational use the Live like BartPe or WinPE disc to boot up the laptop.
