Ubuntu 17.10与Windows 10双系统安装时分区显示不一致求助
Hey there! I’ve helped tons of folks work through this exact partition mismatch issue when setting up dual boot—let’s break down the most likely causes and fixes to get you sorted.
Common Causes & Fixes
1. Windows Fast Startup is Enabled (Most Likely Culprit)
Fast Startup puts your drive into a hybrid hibernation state, which prevents Ubuntu from properly reading the full partition table. Here’s how to disable it:
- Open Windows Control Panel, navigate to Power Options
- Click Choose what the power buttons do, then select Change settings that are currently unavailable
- Uncheck the box next to Turn on fast startup (recommended)
- Save changes, restart your computer, and boot back into the Ubuntu installer to check if partitions now match.
2. BitLocker Encryption is Active
If any of your Windows partitions are encrypted with BitLocker, Ubuntu won’t be able to recognize them. To check:
- Right-click This PC > Manage > Disk Management—look for partitions labeled with "BitLocker"
- Or search for BitLocker in the Windows start menu to open the encryption settings
- If enabled, you’ll need to decrypt the drive (or temporarily suspend encryption, though full decryption is more reliable) before proceeding with Ubuntu installation.
3. Windows Hidden Partitions Are Showing Up
Windows hides system-critical partitions (like the EFI boot partition, recovery partition, or reserved partitions) from the "This PC" view, but Ubuntu’s installer will display all partitions. This makes it look like there are more partitions than you see in Windows.
- To confirm, match the partition sizes: your 87GB empty E drive should be easy to spot in the Ubuntu installer. Use that empty space to create your Ubuntu partitions (e.g., a root
/partition, swap partition, etc.).
4. Corrupted Partition Table
Rarely, a corrupted partition table can cause mismatched displays. Fix this in Windows first:
- Right-click each visible partition (C, D, E) > Properties > Tools > Check
- Let Windows scan and repair any disk errors, then reboot and check the Ubuntu installer again.
Final Tip
If you’re still unsure which partition is which, take a screenshot of both the Windows Disk Management screen and the Ubuntu installer partition screen—comparing sizes will help you map them correctly.
