    当电脑出现系统问题时,很多用户会选择重装win10系统,但是在重装过程中,总会遇到问题

    ,如重装win10系统出现磁盘布局不受UEFI固件支持怎么解决?下面教大家详细的解决方法,

    希望对你们有所帮助!

    1、进入云骑士U盘启动盘PE系统,云骑士u盘启动盘制作教程。

    2、打开磁盘分区工具,比如DiskGenius,将硬盘分区表转换成GPT格式;

    12c690524bee2f1cc9ce930ea19ad484.png

    3、预留228MB可用空间,按下Win+R输入cmd打开命令提示符;

    4、依次输入以下命令,按回车执行;

    diskpart

    list disk

    select disk 0(0是执行list disk之后显示的硬盘标识,一般是0和1)

    create partition efi size=100

    format quick fs=fat32

    create partition msr size=128

    format quick fs=ntfs

    exit

    4、接着输入bcdboot C:windows /l zh-cn,回车,C表示系统盘盘符;

    5、最后重启电脑系统,重装系统win10。

    UEFI 方式安装 Redhat Enterprise Linux 6.5

     

    1、             必须用uefi方式启动dvd;

    否则分区是不出现efi格式,同时会提示swap没有uuid

    2、             必须创建一个 /boot/efi 分区,一般为第一个分区,格式为 efi system partition 200M

    否则uefi的启动列表中不会出现这个启动盘

    3、             必须创建/boot分区,ext4格式         500M

    否则启动会停在开始位置

    以上三条都经过几次失败后得到的。

    4、             创建根区等其它分区

    启动后可以用 efibootmgr 管理efi选项

    安装时会提示 boot loader装在 /dev/sda1,即 /boot/efi分区,如下图:


    第一次按上述方式安装,选择basic server安装包,成功!

    第二次选全部安装包,其它不变,失败,卡死在tboot.gz引导项上,见下图:


    用grub的命令行方式手工引导:

    kernel  /vmlinuz  tab补齐

    initrd /initram tab补齐

    boot

    可以引导成功。

     

    下面是用grub命令行抓取的fstab以及grub.conf文件

    cat (hd0,3)/etc/fstab

    注意巧用tab补齐命令

     



    看来是tboot的问题。

    网上搜索到:

    经过和RedHat确认,RHEL6.3在UEFI模式下不支持TBOOT,在安装过程中,不能选择安装“tboot”软件包。RedHat官方网站关于该问题的描述:https://access.redhat.com/knowledge/articles/186583。

    • Trusted Execution Technology(TXT) and tboot are supported inRHEL 6 when using legacy BIOS. TXT and tboot will does not workwith uEFI mode enabled. With uEFI and tboot enabled the server willnot boot.

    ·        解决方案:

    ·        如下图所示,在安装过程中,不要选择安装tboot-1.7.0-2.el6.x86_64.rpm软件包。

    1.GPT分区详解

    GPT(EFI信息区)

    起始于磁盘的LBA1,通常也只占用这个单一扇区。其作用是定义分区表的位置和大小。GPT头还包含头和分区表的校验和,这样就可以及时发现错误。

    分区表

    分区表区域包含分区表项。这个区域由GPT头定义,一般占用磁盘LBA2~LBA33扇区。分区表中的每个分区项由起始地址、结束地址、类型值、名字、属性标志、GUID值(用GUID表示的分区类型)组成。分区表建立后,128位(16字节)的GUID对系统来说是唯一的。

    GPT分区

    最大的区域,由分配给分区的扇区组成。这个区域的起始和结束地址由GPT头定义。

    备份区

    备份区域位于磁盘的尾部,包含GPT头和分区表的备份。它占用GPT结束扇区和EFI结束扇区之间的33个扇区。其中最后一个扇区用来备份1号扇区的EFI信息,其余的32个扇区用来备份LBA2~LBA33扇区的分区表。

    ·  系统开机 - 上电自检(Power On Self Test 或 POST)。

    ·  UEFI 固件被加载,并由它初始化启动要用的硬件。

    ·  固件读取其引导管理器以确定从何处(比如,从哪个硬盘及分区)加载哪个UEFI 应用。

    ·  固件按照引导管理器中的启动项目,加载UEFI 应用。

    ·  已启动的 UEFI 应用还可以启动其他应用(对应于 UEFI shell 或 rEFInd 之类的引导管理器的情况)或者启动内核及initramfs(对应于GRUB之类引导器的情况),这取决于 UEFI 应用的配置。

    启动管理器将尝试按全局 NVRAM 变量定义的顺序依次加载 UEFI 驱动和 UEFI 应用程序(包括 UEFI 操作系统启动装载程序)。”

    UEFI已具备文件系统的支持,它能够直接读取FAT分区中的文件。可开发出直接在UEFI下运行的应用程序,这类程序文件通常以efi结尾。所以完全可以将Windows安装程序做成efi类型应用程序,然后把它放到任意fat分区中直接运行即可
