Create Windows 10 bootable USB on Linux

The following commands install the WoeUSB program used to create a bootable USB stick for the installation of Windows 10.

First add the repository (assuming Ubuntu or Linux Mint OS)

sudo add-apt-repository ppa:nilarimogard/webupd8

sudo apt-get update

sudo apt-get install woeusb

The WoeUSB GUI can be found in your Applications Menu but I don’t recommend it. The likelihood is, you’ll run into the problem described here

Using gparted, create a NTFS partition on your USB stick – you may need to install ntfs-tools from your repository to do this.

Create the USB stick using the following command

sudo umount /dev/sdb1

sudo woesub –target-filesystem NTFS –device Win10_1809Oct_EnglishInternational_x64.iso /dev/sdb

Download the Windows 10 ISO from Microsoft here

nohup and disown your long running jobs

Ever started a job and thought “this is running on a bit longer than I expected”, then wondered whats going to happen when you go home and come back in to work tomorrow morning to find your remote session gone, which leaves you wondering “did that job complete?”.


Mmm, me too, which is where the nohup or disown commands come in.  nohup (no hangup) is a well known job control utility which will prevent a process from reacting to the hangup signal when a shell is disconnected.  Usually you’d preceed your actual command with it, e.g.

nohup rsync -auvc /Source/* /Destination/

but if your command is already running, you’re left wishing you’d nohup‘d it to start with – unless you’re running Solaris or AIX in which case the nohup command has a convenient -p switch to specify the process id (use ps -ef | grep rsync to obtain the PID of that long running data migration process, then nohup -p 9675 (or whatever the PID is of your running job).

If you’re not running Solaris or AIX, then pray you started the command in the bash shell (Linux default shell so more likely than not).  If you did, then you can

CTRL-Z

to pause the current job running in the foreground, then use the

jobs

command to determine its job number (most likely 1 if there’s no other sysadmins running backgrounded jobs), then background the process with

bg 1 

then finally

disown %1

to disconnect the process from the current shell.  Running

jobs 

again will show that your job is no longer in the list, but

ps -ef

will reveal that it is in fact still running.

Your shell can now be closed without the fear of your running job being killed with it.  Yay.
