30-Second Installation

1

Download the ISO

Grab the version that matches your VirtualBox installation. To find your version: Help → About VirtualBox (or run VBoxManage --version in terminal).

2

Mount it in your VM

Devices → Insert Guest Additions CD image is the preferred method. If that fails (why you're here), use Devices → Optical Drives → Choose a disk file... and select the downloaded ISO.

3

Run the installer

Windows: Run VBoxWindowsAdditions.exe (auto-starts or run from CD)
Linux: Install build-essential linux-headers dkms first, then sudo ./VBoxLinuxAdditions.run
macOS guest: Run VBoxDarwinAdditions.pkg from the mounted ISO

4

Reboot and enjoy

Clipboard sharing, drag-and-drop, seamless mode, shared folders — it all works now.

? Frequently Asked

VirtualBox ships with VBoxGuestAdditions.iso bundled (Windows: C:\Program Files\Oracle\VirtualBox\; Linux/macOS: /opt/VirtualBox/). Common causes of failure: distro repacks omitting it (install virtualbox-guest-additions package), permissions issues, firewalls, or file corruption. Use manual mounting or grab the ISO directly from this site.
Minor mismatches work (7.1.6 Additions on 7.1.10 host = fine). Major mismatches (6.x on 7.x) cause driver failures. Match your host version via Help → About VirtualBox for zero issues.
100% safe — direct links from download.virtualbox.org (Oracle's servers). SHA256 checksums match official releases. No repacks, no malware, no middleman.
VM Settings → General → Advanced → Shared Clipboard → Bidirectional (defaults Disabled for security).
Also check runtime: Devices → Shared Clipboard → Bidirectional.
Reboot guest after changes. Linux users may need: sudo VBoxClient --clipboard.
Guest Additions + correct settings + reboot = all required.
Install prerequisites first:

Debian/Ubuntu: sudo apt install build-essential linux-headers-$(uname -r) dkms
Fedora: sudo dnf install kernel-devel kernel-headers gcc make dkms
Arch: sudo pacman -S linux-headers base-devel dkms

Then run sudo ./VBoxLinuxAdditions.run. Reinstall after kernel updates.
Enable Bidirectional in VM Settings → General → Advanced → Drag and Drop + Devices menu. Requires Guest Additions installed + reboot. Host/guest firewall may block file transfers.
Add via VM Settings → Shared Folders → Add folder → enable Auto-mount + Make Permanent.
Linux users need: sudo usermod -aG vboxsf $USER then logout/login.
After running VBoxDarwinAdditions.pkg, approve Oracle/VirtualBox in System Settings → Privacy & Security. Reboot required.
Run as Administrator. Temporarily disable antivirus. Use matching version. Check VBoxWindowsAdditions.log in %TEMP% for errors.
