How to Create a Bootable Dormant Partition?

[Satyajit Mishra]

- I want to create a Bootable (Active) partition within my NVMe M.2 SSD.
- I want to do this because I want a hassle free way of easily & quickly installing windows without involving Bootable USB Flash Drive or DVD.
- Also I want to keep this partition Dormant (Un-mounted via Disk Management) for future use.

Can some please give a Step-By-Step Guide of doing so?

For UEFI-CSM mode this would be like:

• 1. convert storage device to MBR partitioning;
  2. create primary 5GB partition (windows 10 install is between 4 and 5 GB);
  3. mark partition active;
  4. format to ntfs;
  5. copy installation files from installation media;
  6. run on created volume
  • bootrec /fixmbr
    bootsect /nt60

For UEFI mode - this would be slightly different:

• 1. convert storage device to GPT partitioning;
  2. create EFI system 5GB partition;
  3. format to fat32;
  4. copy installation files from installation media;
  5. run on created volume
  • bootrec /fixmbr
    bootsect /nt60

NOTE: When you do preparations and install windows, make sure only OS drive is connected. Connect Seagate barracuda only after OS is installed.
