Windows 10: Lost boot partition

I recently upgraded to a Samsung 2TB drive, using the Samsung Data Migration software to clone my existing drive. In the process, the boot sector did not clone. How do I recreate the boot sector in order to create a Windows 10 recovery drive?

lost boot and system partition!!

Hi,

My name is Rogelio. I am an Independent Advisor. Thanks for contacting our support.

Even if a partition contains bootable data, your computer might sometimes fail to detect it as a suitable bootable partition. This is usually due to the fact that, to be recognized by your computer as a bootable partition, a partition does not only need to
contain a bootable environment, it also needs to be specifically marked as an active system partition. You can add that active marker to a hard drive partition by using Diskpart, a command-line disk management application that is built into Windows.

Step 1

Open the Windows Start screen and type "cmd." Right-click on the "Command-Line Prompt" shortcut and select "Run as administrator."

Step 2

Type "diskpart" and press the "Return" key. Diskpart will now launch. While Diskpart is active, the traditional command-line prompt will be replaced by a Diskpart prompt, indicating that any command you enter will be processed by that application.

Step 3

Enter "list disk" and press the "Return" key. Note the number assigned to the drive which contains the partition you wish to make bootable. You can find that number in the first column.

Step 4

Type "select disk X", replacing "X" with the number assigned to the relevant drive. Press the "Enter" key.

Step 5

Enter "list partition" and press the "Return" key. Note the number assigned to the partition you want to make bootable.

Step 6

Type "select partition X", replacing "X" with the number of the partition you want to select. Press the "Enter" key.

Step 7

Enter "active" and press the "Return" key to instruct Diskpart to mark that partition as an active, bootable partition.

Step 8

Type "exit," followed by the "Return" key, to exit Diskpart. Close the Command-Line Prompt window.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

How to go about building a tri-boot system?

i dual boot all the time, and going in to tri boot is easy.

step 1) partition the drive in to 3 partitions ( leaving 1 empty for the linux installer. )
step 2) install windows on the first 2 partitions.
step 3) install linux, and let it auto partition the remaining space. ( i recommend at least 30gb of space for linux, because it will make things a lot easier. )

step 4) enjoy.
