The steps I took to dual boot Arch Linux alongside the preinstalled Windows 10 that came with my new Lenovo Ideapad. I used Ubuntu exclusively for the last 6 years so I'm Window's illiterate. I don't know a whole lot about the inner workings of Linux either.
Prepare the preinstalled Windows to share the system.
| # Install ARCH Linux with encrypted file-system and UEFI | |
| # The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description. | |
| # Download the archiso image from https://www.archlinux.org/ | |
| # Copy to a usb-drive | |
| dd if=archlinux.img of=/dev/sdX bs=16M && sync # on linux | |
| # Boot from the usb. If the usb fails to boot, make sure that secure boot is disabled in the BIOS configuration. | |
| # Set swedish keymap |
