I run a HP laptop with Windows 10 (10.0.15063) with the Creators Update applied and I have been having some problems with logging-in after waking up from sleep or hibernate. Sometimes the account/password page will not appear, sometimes it gets stuck after I enter the password. I can log back in after restarting the computer.
I have tried going into the Advanced boot options menu to run startup repair, but I've got the message "Windows 10 Automatic Repair Couldn’t Repair Your PC". Digging a bit deeper, I was trying to rebuild the BCD in my machine with the command prompt option from advanced option. It's interesting to see that by default the cmd starts in the X:/ drive. Also, it appears that C:\boot does not exist. Instead, there are BCDs in D:\boot and D:\EFI\Microsoft\Boot folders. The D:\ drive is a recovery drive I believe
After some successful restarts, I can no longer access the advanced options in the advanced start up options, the case is similar to https://www.tenforums.com/installation-upgrade/34131-windows-10-troubleshoot-advanced-options-missing.html, under Troubleshoot, only UEFI and startup settings are available.
My computer seems to be booting up ok now but it looks like there are some problems with the drive mapping etc.
