我尝试升级到 Windows 10，并期望它会覆盖引导加载程序，但它也搞砸了分区表。所以我想知道是否有任何方法可以恢复Linux安装。
以下是启动修复日志的摘录：
============================ Drive/Partition Info: =============================
Drive: sda _____________________________________________________________________
Disk /dev/sda: 480.1 GB, 480103981056 bytes
255 heads, 63 sectors/track, 58369 cylinders, total 937703088 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
Partition Boot Start Sector End Sector # of Sectors Id System
/dev/sda1 * 2,048 718,847 716,800 7 NTFS / exFAT / HPFS
/dev/sda2 718,848 546,152,716 545,433,869 7 NTFS / exFAT / HPFS
/dev/sda3 546,154,496 547,074,047 919,552 27 Hidden NTFS (Recovery Environment)
/dev/sda4 547,076,094 937,701,375 390,625,282 5 Extended
/dev/sda5 ? 1,872,973,105 5,529,806,839 3,656,833,735 fd Linux raid autodetect
/dev/sda6 ? 2,139,002,515 2,179,868,678 40,866,164 23 Unknown
/dev/sda5 ends after the last sector of /dev/sda
the logical partition /dev/sda5 is not contained in the extended partition /dev/sda4
/dev/sda5 overlaps with /dev/sda6
/dev/sda6 ends after the last sector of /dev/sda
the logical partition /dev/sda6 is not contained in the extended partition /dev/sda4
请注意，sda5 比可能的扇区总数大几倍，并且它在驱动器末尾之后开始。
理论上如果我知道逻辑分区的起始和结束扇区，我可以重写该表吗？

我真的希望除了“有人能帮助我吗？”之外，我有一个更准确的问题要问。但这超出了我的经验，我什至不知道我想问什么。提前致谢
