硬盘仅30GB且Windows 10占满空间，如何安装Ubuntu替代？
Hey Eric, totally get where you’re coming from—dealing with a cramped Windows install that won’t even update is such a frustration, especially when you’re sick of Windows entirely. Let’s walk through your options step by step:
This is the straightforward solution that fits your goal of switching to a fully free platform, and it’s perfect for your 30GB drive:
- First, back up any important files from your Windows install (since this will wipe everything on the internal drive).
- Create a bootable Ubuntu USB drive using another computer (you can use the official Ubuntu Desktop installer tool to do this).
- Plug the USB into your HP laptop, boot from it (you may need to press F9/F12 during startup to select the USB as the boot device).
- When you get to the installation type screen, select "Erase disk and install Ubuntu"—this will completely remove Windows 10 and set up Ubuntu on your 30GB drive.
- Ubuntu’s base install takes roughly 20-25GB, so you’ll have a few GB left over for updates, basic apps, and files. Even better, if you choose the "Minimal Installation" option during setup (which skips pre-installed apps like LibreOffice), you’ll only use ~10-15GB, leaving even more room.
If for some reason you don’t want to wipe Windows (though you mentioned you hate it, so this might not be necessary), you can install Ubuntu directly to an external USB drive or portable hard drive:
- Follow the same steps to create a bootable Ubuntu USB.
- Connect your external drive to the laptop, then boot from the Ubuntu installer USB.
- On the installation type screen, select "Something else"—this lets you manually choose where to install Ubuntu.
- Format the external drive (make sure you pick the right one, not your internal Windows drive!) and set it as the root partition (
/), then set the boot loader installation to the same external drive. - After installation, you’ll be able to boot into Ubuntu by selecting the external drive from your laptop’s boot menu. Your internal Windows drive will stay untouched, but you can ignore it entirely if you want.
Just to confirm: Ubuntu is 100% free to use, no activation fees, no hidden costs. All the software in its official repositories is also free, and you’ll get regular security and feature updates at no charge—exactly what you’re looking for.
If you run into any snags during the USB creation or installation, feel free to ask for more details!
