From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I want to install Debian directly onto my USB drive. Is there an easy way to do this directly without having to reboot to run the installer?

without having to reboot to run the installer?

I'm not sure that I understand what you mean. Are you saying that you want to be able to load the OS without having to reboot your computer? Or are you saying that you just don't want to have to click the equivalent of "try the OS" when booting a live USB? If it's the latter, you should be able to just select the flash drive as the install point (though, tbc, I have never tried this, but I don't see why it wouldn't work) (I think you'd need 2 USBs, though — you'd need 1 to be the installer source, and one to be the install point — I don't think theres any installer that can run as a desktop application. Though, if it's Arch Linux, you might actually be able to call pacstrap from the host OS — I've never tried this after having already installed the OS). There's even OS's that are specifically designed to be ephemeral on hardware in this way — eg Tails OS.
