Dual-booting between Linux and Windows, or even between two distinct Linux distributions, offers the best of both worlds—the versatility of Linux and the familiarity or specialized needs addressed by Windows. Yet, every dual-booter at some point confronts a daunting scenario: suddenly, one of...

Hello mob! Yesterday I was installing Linux Mint on a USB key, I repeat, ON, from another live USB key, and at some point GRUB took the place of the Windows Bootloader. I am not sure when, as everything was installed on the USB key, with the bootloader was to be put on the USB key, I even...
