咨询：在Windows 10旁安装Ubuntu的操作选项困惑

Hey there! I totally get why this is confusing—those tutorial prompts can be a bit vague sometimes. Let me walk you through exactly what to do:

When you reach the Installation Type step in the Ubuntu installer, the program will automatically detect your existing Windows 10 installation. The prompt you mentioned:

Use the checkboxes to choose whether you'd like to Install Ubuntu alongside another operating system

is a bit misleading in wording. You won’t need to hunt for a separate checkbox here. Instead, you’ll see a pre-made option (usually labeled "Install Ubuntu alongside Windows Boot Manager"—or a similar localized version like "与Windows 10共存安装" if you’re using a Chinese installer) that’s specifically designed for dual-booting with Windows.

What to do next: #

• Select that "Install Ubuntu alongside Windows Boot Manager" option.
• You’ll see a slider that lets you adjust how much disk space you want to allocate to Ubuntu (this space will be taken from your existing Windows partition, so make sure you have enough free space).
• Once you’re happy with the space allocation, click Install Now and follow the rest of the installation prompts.

Quick pre-install tips to avoid issues: #

• Make sure you’ve disabled Fast Startup in Windows 10 (go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Uncheck "Turn on fast startup"). This prevents disk conflicts between the two OSes.
• Back up any important data on your Windows drive before starting—better safe than sorry!

After installation finishes and you restart your computer, you’ll see the GRUB boot menu, where you can choose to boot into Ubuntu or Windows 10.
