How to Create a bootable Windows 2012 R2 USB Disk

Pre-requisites: 7-Zip software (Download it from here: http://7-zip.org/), Windows 2012 (R2) ISO (or Windows 8.1 ISO), 8GB or more USB disk

Open Command Prompt in elevated mode (Run as Administrator)

Type diskpart and press Enter

Type list disk and press Enter. Note the list of existing disks.

Insert the USB Disk

Type list disk and press enter again. Note the new disk showed up which is our USB disk. I assume the new disk is 2 for example purpose.

Type select disk X where X is your USB disk. E.g., select disk 2. Press Enter.

Type clean and press enter.

Type create partition primary and press enter to create primary partition 1.

Type select partition 1 and press enter.

Type active and press enter to make the partition 1 active

Type format fs=ntfs and press enter. This will format the partition 1 as NTFS volume.

Type assign and press enter to assign the USB disk to a drive letter.

Type exit

Leaving DiskPart...

Mount the ISO you downloaded earlier and copy the entire content to the root of the USB stick we just created.

Once the copy is complete, change your focus to the USB drive ( mine is mapped as drive E: ) navigate to the Boot directory and update the boot manager using the following command from an elevated command prompt windows.

This is the part we was missing...

C:\WINDOWS\system32>e:

type CD BOOT

Create a boot sector on the USB drive (in our case it was assigned the letter e:):

bootsect /nt60 e:



Example:

Código: Seleccionar todo

E:\boot>BOOTSECT.EXE /NT60 D:

Target volumes will be updated with BOOTMGR compatible bootcode.
 
D: (\\?\Volume{75299495-0000-0000-0000-100000000000})
 
    Successfully updated FAT32 filesystem bootcode.
 
Bootcode was successfully updated on all targeted volumes.
 

E:\boot>

type exit

Once the Boot manager is updated. you can use the stick to boot and install Windows

Did it help you? Leave me a Thanks.
