内存交换后无效的主GPT标头

我正在尝试使用本教程安全地将空间从Windows 7/8/10移动到Ubuntu（GPT + UEFI模式）。

我尝试编辑/etc/fstab来告诉它有关新交换的信息并检查是否有任何分区的UUID有任何更改，以便编辑它们（如果有的话）。 但是，当我为Linux gparted启动文本模式分区工具时，它告诉我较旧的主引导记录是有效的

 root@ubuntu:/home/ubuntu# gdisk -l /dev/sda GPT fdisk (gdisk) version 1.0.1 Caution: invalid main GPT header, but valid backup; regenerating main header from backup! Caution! After loading partitions, the CRC doesn't check out! Warning! Main partition table CRC mismatch! Loaded backup partition table instead of main partition table! Warning! One or more CRCs don't match. You should repair the disk! Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: damaged Found valid MBR and corrupt GPT. Which do you want to use? (Using the GPT MAY permit recovery of GPT data.) 1 - MBR 2 - GPT 3 - Create blank GPT Your answer: 2 Disk /dev/sda: 1953525168 sectors, 931.5 GiB Logical sector size: 512 bytes Disk identifier (GUID): 6FAF53FA-01E2-4754-A71C-9AF3A67E5F84 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 1953525134 Partitions will be aligned on 2048-sector boundaries Total free space is 1953525101 sectors (931.5 GiB) Number Start (sector) End (sector) Size Code Name root@ubuntu:/home/ubuntu# 

然而，我有一个完全不同的系统：

它应该或多或少是这样的：
