分区共享 - 搞砸了GPT / MBR

0

首先，对于任何英语错误或法语打印屏幕抱歉......我是比利时人。

我的iMac 2009 27“有很多问题，主要是Mac OS。奇怪的是，Windows（10）几乎没有问题，所以我最终决定只运行这台电脑。嗯...老实说，我甚至试图安装Ubuntu，但很快就放弃了。

我放弃Mac OS导致我重新分区驱动器...我保留了Mac OS驱动器，bootcamp一个，创建了一个共享分区，（以防万一，但我想删除它们）两个分区Linux（操作系统和交换）。

之后...... Windows拒绝启动。我设法找到了“修复”MBR（或GPT？）的解决方案。Windows靴子，但我不确定我做的一切都很完美。

我现在面临的一个大问题是，我想访问我的Share分区。我可以，从Mac OS。但是从windows中，我所有的其他分区都显示为“GPT保护分区”。我似乎无能为力。

在此输入图像描述

我希望能够访问此共享分区。更好的是，我想将这个共享分区与两个Linux分区合并。但我不想再丢失数据或拧掉我的MBR / GPT。

我目前在Windows上......当我的计算机变冷时，它将在Mac OS上启动（当温暖时它不会启动mac os，这是我的主要问题），并为您提供任何其他所需信息。

提前，谢谢你的帮助！

屏幕截图没有多大帮助，因为共享和Linux分区都不可见。启动到OS X并进入sudo gpt -r show /dev/disk0终端或在Windows中安装一个不错的分区工具（适用于Windows的hmm gdisk应该可以工作）并发布结果。
— klanomath 2016年
很好的工作填写@ klanomath的要求。你可以添加输出吗sudo fdisk /dev/disk0？此外，您使用的是什么版本的OS X. 我还可以假设要共享的分区是320.9 GB disk0s6吗？
— 大卫安德森
我明天会发布两个命令行的结果。对于其他问题：El Capitan，是的，disk0s6应该是共享的。我很乐意将它与s4和s5合并，如果可能的话没有风险，因为我放弃了安装ubuntu的想法。

我根据您的要求编辑了第一篇文章。我希望你有一个解决方案......

固定访问共享分区

要使Windows启动，您可以尝试gdisk从OS X 输入以下内容。在输入命令之前，您必须禁用系统完整性保护（SIP）。如果Windows启动，您将能够从Windows访问新的共享分区。如果Windows无法启动，请按照“不使用共享分区进行修复”一节中的说明进行操作。

它起作用了，Windows靴子吧！非常感谢。实际上，我仍然无法访问数据（共享）分区。
— capi-ch 40年
@ capi-chou：我可以发布允许Windows查看共享分区的说明。如果您按照说明操作，Windows可能无法启动。如果发生这种情况，您将需要执行该命令bootrec，该命令将重建该C:\boot\BCD文件。此命令只能从Windows安装媒体运行。运行该命令后，Windows将再次启动。那么你有Windows安装DVD吗？你想继续吗？
— 大卫安德森
我可能仍然有一个旧的Windows DVD somwhere，但我的光驱仍然死了。但是如果一个usb恢复驱动器足够了（我想我只需要访问DOS命令行），你就可以继续了。
— capi-ch 40年
@ capi-chou：我更新了我的答案。您可以尝试查看Windows是否能够访问共享分区。您可能不需要Windows安装媒体。如果这样做，则无法从DVD（光纤）驱动器启动。无法从Mac型号的USB端口启动Windows安装媒体。
— 大卫安德森
我试过你的“可以访问共享分区”。好消息：窗户还在靴子里。好消息：我可以从Windows磁盘管理中看到共享卷。坏消息：它显示为“未分配”。我可以构建一个新卷...但是我得到一个警告说这会使安装在同一个驱动器上的任何其他操作系统无法启动。我没有冒风险......我可以吗？
