## Create a Bootlabe Windows 10 USB Drive using LINUX Arch

A manual from the site [adamsdesk](https://kb.adamsdesk.com/operating_system/create_a_bootable_windows_10_usb_using_linux/), was adapted to my needs.
*Version 1.0*

### Prerequisite

#### Assumptions
 * Instructions using Arch Linux
 * USB drive with a minimum of 8 GB
 * Steps prefixed with "$" represents the CLI prompt with normal user access rights
 * Steps prefixed with "#" represents the CLI prompt with root access rights

#### Preparation
Install the following packages from the Arch Linux distribution

```
$ yay -Sy ms-sys ntfs-3g rsync
```

### Instructions

1. Download the latest Windows ISO from Microsoft [here](https://www.microsoft.com/en-us/software-download/windows10ISO),
2. Plug in the USB flash drive,
3. Locate the USB device name: 
	```
	$ lsblk
	```
	```
	NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
	loop0     7:0    0  5,7G  0 loop /mnt/iso
	sda       8:0    1  7,5G  0 disk 
	└─sda1    8:1    1  7,5G  0 part 
	nvme0n1 259:0    0  1,8T  0 disk /
	```
4. Unmount the UB flash drive:
	```
	# umount /dev/sda1
	```
5. Create USB flash drive partition:
	```
	# fdisk /dev/sda
	```

	a.) Press `D` then press `<ENTER>` to delete all partitions,

	b.) Press `N` then press `<ENTER>` to create a new partition,

	c.) Press `<ENTER>` to accept default (p for primary),

	d.) Press `<ENTER>` to accept default partition number, 1,

	e.) Press `<ENTER>` to accept default first sector,

	f.) Press `<ENTER>` to accept default last sector,

	```
	Note:
	Say yes if prompted for "Do you want to remove the signature". 
	```

	g.) Press `T` then press `<ENTER>` to change partition type,

	h.) Press `7` then press `<ENTER>` to set partion type to **HPFS/NTFS/exFAT**,

	i.) Press `P` to verify:
	```
	Disk /dev/sda: 7,5 GiB, 8053063680 bytes, 15728640 sectors
	Disk model: Flash Disk      
	Units: sectors of 1 * 512 = 512 bytes
	Sector size (logical/physical): 512 bytes / 512 bytes
	I/O size (minimum/optimal): 512 bytes / 512 bytes
	Disklabel type: dos
	Disk identifier: 0x8bfaef3a

	Device     Boot Start      End  Sectors  Size Id Type
	/dev/sda1        2048 15728639 15726592  7,5G  7 HPFS/NTFS/exFAT
	```

	j.) Press `W` then press `<ENTER>` to write table to disk and exit,

6. Format partition file system to NTFS:
	```
	# mkfs.ntfs -L win10 /dev/sda1
	```
7. Create mount points:
	```
	# mkdir /mnt/{iso,usb}
	```
8. Mount Windows ISO:
	```
	# mount ~<username>/Downloads/Win10_22H2_English_x16v1.iso /mnt/iso
	```
9. Mount USB drive partition:
	```
	# mount /dev/sda1 /mnt/usb
	```
10. Copy files from Windows ISO to USB flash drive using `rsync`:
	```
	# rsync -avP /mnt/iso/ /mnt/usb/
	```
11. Make USB flash drive bootable with:
	```
	# ms-sys -7 /dev/sda
	```
	```
	Windows 7 master boot record successfully written to /dev/sda
	```
12. Run **sync** to ensure all operations have completet,
	```
	# sync
	```
13. Unmount USB flash drive,
	```
	# umount /mnt/usb
	```
14. Unmount Windows ISO,
	```
	# umount /mnt/iso
	```
15. Remove mount point directories:
	```
	# rm -r /mnt/{iso,usb}
	```
