Lenovo 开机卡屏

有朋友看到这篇文字之后，跟老王说，这个错误可能跟硬盘错误有关，并且建议平时做好备份。备份的确很重要，可以自己拿移动硬盘，或者DVD备份。我也用Onedrive。文件可以同步上传云端，平时也就不用担心资料的备份问题。

有台Leonovo的笔记本电脑，19年初买的，非触摸屏。前几天突然就开不了机了，卡在Logo上，过一段时间就黑屏了，虽然看得出电源还是开着的。

然后… 就没有然后了，按Enter也没有反应。F8, F12, F1都不管用。

本来约好了太平洋电脑去修的，

后来想起来我这个有三年的上门服务呢。打电话给 Lenovo 的技术支持，接电话的小伙子听了我的说明，知道我已经在网上搜过各种解决办法都不好使以后，本来要派人上门来修理的。但后来改主意了，说这个应该是软件问题，来的人只能换个硬盘什么的。大概后来又去查了一下，说是 Windows 升级把 Boot 给弄坏了，可以自己修。给我发了个邮件，内容如下：

Quick Version: The updates broke the EFI (Boot) Partition on the NVMe drive ( or least severed the communication with the Windows boot Manager). Recreating the EFI partition resolves the issue and allows for the boot manager to work as expected.

Before you begin, you will need:

1x 16+GB USB drive
The win10 ISO tool creator here
Access to the Bitlocker Recovery Key for the laptop in question if needed

Steps:

Install the Win 10 image onto the USB disk on a separate computer
While powered off, boot into the USB drive ( you may need to a. disable secure boot in the BIOS. B. change the boot order to put the USB drive at the top).
In the repair disk, do the following.

1. Select troubleshoot – command prompt
2. Once in the command prompt, type DISKPART
3. Type LIST DISK, then SELECT DISK # ( Disk should be about 250GB in size)
4. Type LIST PARTITION, then SELECT PARTITION # ( the # being the System partition under the size column of partition results)
5. Then we will assign the Partition a drive letter Assign Letter =S (type “assign letter=S”)
6. Type exit to leave diskpart
7. Navigate to the S drive by typing S:
8. In S: type FORMAT S: /FS:FAT32 , then type Y x 2 to reformat the partition 注意：这里在输入两次Y，也就是Yes之前，还有一个问题，Enter current volume label for drive S:，我也不知道是啥啊，后来试了几次，原来就是那个System.
9. Once that finishes, in the root of S: type BCDBOOT C:\Windows /s S: /f UEFI
10. Type exit in the command prompt Select CONTINUE to Windows 10 in the Boot menu.
