“磁碟外不能有分區！”對於從截斷圖像創建的 vdi

我曾經dd創建僅包含分配空間的磁碟的部分/截斷圖像，然後將其轉換為 VirtualBox 的 vdi 文件。我已成功使用 vdi 映像執行安裝在磁碟上的 Linux (Ubuntu)。

現在我不想執行 GParted 來刪除位於 Linux 分區之前的分區（這樣我就可以創建一個更小的映像）。但是 GParted 不起作用。它將整個磁碟顯示為未分配。我該如何解決？

也許最簡單的解決方案是增加圖像的大小以gparted再次變得快樂。這很可能是一次性問題，因此將圖像大小增加幾兆字節就足夠了：

dd if=/dev/zero of=newimage.raw bs=1M count=102400
qemu-img convert -f vdi oldimage.vdi -O raw oldimage.raw
dd if=oldimage.raw of=newimage.raw count=190877695 conv=notrunc
qemu-img convert -f raw newimage.raw -O vdi newimage.vdi

或者簡單地說：

cp oldimage.vdi newimage.vdi
VBoxManage modifyhd /path/to/newimage.vdi --resize 102400

然後你應該重試gparted執行newimage.vdi。如果仍然報錯，您可以嘗試將映像的大小增加到原始磁碟大小，前提是您有足夠的空間。
