How can I safely install Linux on my secondhand Acer laptop?

Before installing, decide whether you want to erase Windows or keep it. Erasing the disk is simpler if you don’t need Windows, but make absolutely sure your files are backed up first. If you want both systems, shrink the Windows partition using Windows Disk Management and leave the resulting space unallocated. During installation, choose the option to install Linux alongside Windows or use the free space. A dual boot gives you a safety net while you learn.

Starting with a live USB is a good way to gain confidence without changing the internal drive. You can use Linux directly from the USB and practice opening applications, connecting to Wi-Fi, and exploring the desktop. It will run more slowly than an installed system, but it lets you check hardware compatibility before committing to an installation.

You can’t physically damage the laptop by installing an operating system, so the main risk is losing data or choosing the wrong disk option. Back up anything important first. Linux Mint Xfce, Lubuntu, or a similar lightweight distribution should work reasonably well with 4 GB of RAM. Download the ISO from the project’s official site, write it to an 8 GB or larger USB drive, boot the laptop from that USB, and try the live desktop before installing. Test Wi-Fi, sound, display, and sleep mode. If everything works, the installer will guide you through the process.

For a beginner, Mint Xfce is a sensible choice because it has a familiar desktop and doesn’t demand much from the hardware. Ubuntu-based options such as Xubuntu or Lubuntu are also worth considering. The machine may feel faster than it did with Windows, although 4 GB of RAM will still be limiting for heavy multitasking, streaming, or memory-hungry applications.

The basic process is: download a Linux ISO, create a bootable USB, restart and open the laptop’s boot menu, select the USB, and choose the live-session option. On Acer laptops, the boot menu is commonly reached with F12, while BIOS settings are often opened with F2; the exact key may vary. You may need to enable the F12 boot menu in firmware settings. Don’t change random BIOS options, and read each installer screen carefully before confirming anything.
