Boot failed and drive locked after Firmware update

I have already solved this issue myself, but perhaps I can help someone else with the same problem.


After installing the latest firmware on my Ideapad 700, I was met with a list of bootable devices (HDD + network cards), none of which worked.


To solve this, I put the Windows 10 installation on a USB flashdrive and booted from it, then navigated to the command prompt (Repair your computer -> Troubleshoot -> Advanced Options -> Command Prompt). From there, I entered the following commands:

sel disk 0
list vol

I noticed that the wrong drive (the FAT32 system partition) had the letter C assigned, so I selected that one and changed it to a free letter:

sel vol 0
assign letter h:

Then changed my Windows drive back to C:

sel vol 1
assign letter c:

I then rebuilt the boot sector (using the FAT32 system partition), just to be safe:

bootrec /fixboot
bcdboot C:\Windows /s h: /f

Then, I rebooted and it went back to Windows! Hope this helps someone. Smiley Happy
