Win10 無法取得 GRUB 條目

Win10 無法取得 GRUB 條目

我無法按照我想要的方式設定我的 (Win10/Ubuntu 15.10) 雙啟動。我有以下驅動器:

  • 500GB SSD - Windows(/dev/sdbBIOS 中預設啟動)
  • 250GB SSD - Ubuntu(/dev/sda這裡安裝了 GRUB)
  • 1TB HDD - 數據,共享

理想情況下,我可以將 Ubuntu 驅動器設定為預設啟動驅動器,如果需要的話,可以讓 GRUB 與 Windows 條目一起啟動。我想盡可能少地干擾 Windows 驅動器,因為我總是以某種奇怪的方式搬起石頭砸自己的腳,需要重新安裝。但是,我似乎無法讓 Ubuntu/GRUB 識別/dev/sdb磁碟機上的 Windows。的輸出sudo fdisk -l給出:

當我跑步時sudo grub-install /dev/sdb,我得到:

Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install: error: embedding is not possible, but this is required for cross-disk install.

運行sudo update-grub只會給出:

運行os-prober不會傳回任何結果。的摘要結果boot-repair位於http://paste.ubuntu.com/13323193/(太長,無法貼到這裡)

我缺少什麼才能將 Windows 新增到 GRUB 清單?

答案1

在 UEFI(而不是舊版 BIOS)中安裝 Ubuntu 使其能夠正確新增適用於 Windows 的 GRUB 條目。
