Writing bootable disk images (.iso, .img, etc.) to a USB stick from Windows

Because Windows doesn’t have dd, and I want to write the latest Mint LTS release to a USB task, I had to face the unpleasant task of finding a Windows tool to perform what’s a basic Unix operation. The good news is that I found one, and it’s open source: Win32 Disk Imager. It even has a version ≥ 1, titled: “Holy cow, we made a 1.0 Release”.

A screenshot of Win32 Disk Imager at work, writing Linux Mint 18.3 MATE 64bit to my SanDisk USB stick.

I found another open source tool, UNetbootin, but that tool didn’t recognize my non-MS-format formatted USB stick (which already tauted the installer for a previous Mint release).

In the end, Win32 Disk Imager also choked on the funky partition table left by the previous boot image, so I had to find out how reset the USB disk’s partition table in Windows:

C:\WINDOWS\system32>diskpart

Making a Compaq Deskpro sff boot without keyboard

To boot a compaq Deskpro sff without keyboard, you need to configure the BIOS in a special way.

I found this:

– Run BIOS setup by pressing F10
– Goto ‘Security’ and ‘Set Power On Password’
– Type in a password and F10 to accept the change
– As soon as password is set, ‘Password Options’ will appear under ‘Security’ tab
– Enable ‘Network Server’ mode in there
– F10 to save changes and exit

When booting up it won’t ask you for F1 anymore. However, if you or
someone else plugs in a keyboard it will ask for a power-on password.

Quickly removing and adding bootscripts in Debian

Debian still uses the System V init scripts, which are very clumsy to use. Here are two Debian commands you might need often:

update-rc.d -f service remove

That will remove all the links in the runlevels to the script in init.d.

update-rc.d service defaults

That will make default start and stop links in all the runlevels.
