本站即刻起，將於未來不定時開始站點搬遷作業。搬到日本機房。屆時，將會有數小時下線，甚至幾天的DNS解析錯誤。此為正常現象。

※更新：本站已於 2017/08/30 12:20 (GMT+8) 搬遷完畢。

Grub 加入 VeraCrypt 開機選單 多系統

好久沒發文了，今天寫篇沒有程度的文章做個小筆記。

最近和同學聊天，正好扯到了加密硬碟，突然想到我自己的電腦 Win10 也是屬於未加密的一類，所以乾脆就用 VeraCrypt加密掉好了，可惜卻出現一個問題就是開機選單只能選單一系統，其他硬碟的系統好像偵測不到一樣，變成灰色的選項不給選。所以只好事後補修這個問題啦。

先開機進入BIOS重新選擇開機選單，開到特定Linux，安裝Grub，

apt-get install grub-efi
Markup

網路上似乎很少人講這個東西。即使有 issue 被提交了，但下面也沒啥人回應。

首先，打開目標文件：/boot/grub/grub.cfg，搜尋 menuentry 'Windows Boot Manager (on /dev/sdb1)'，

然後複製整個 menuentry，在這邊直接修改是沒什麼效果的，到時候Update掉又被OverWritten，打開：/etc/grub.d/40_custom，

在下面直接加入整個 menuentry。以下是示範：

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

menuentry 'Windows 10 VeraCrypt (on /dev/sdb1)' --class windows --class os $menuentry_id_option 'osprober-efi-B673-5372' {
	insmod part_gpt
	insmod fat
	set root='hd1,gpt1'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd1,gpt1 --hint-efi=hd1,gpt1 --hint-baremetal=ahci1,gpt1  B673-5372
	else
	  search --no-floppy --fs-uuid --set=root B673-5372
	fi
	chainloader /EFI/VeraCrypt/DcsBoot.efi
}
Bash

直接改掉 chainloader 的資訊，對應到 /EFI/VeraCrypt/DcsBoot.efi 即可。最後直接輸入指令：

update-grub
Bash

這樣就大功告成了。
