Hi,
If you have not yet resolved this, here are some commands to enter various types of Safe Mode..
There are also commands to exit Safe Mode..
Lately people have been having problems entering Safe Mode if they use a password of any kind as It is being rejected..
Safe Mode:
bcdedit /set {default} safeboot minimal
Safe Mode with Networking:
bcdedit /set {default} safeboot network
Safe Mode with Command Prompt:
bcdedit /set {default} safeboot minimal
bcdedit /set {default} safebootalternateshell yes
To turn off Safe Boot use... bcdedit /deletevalue {default} safeboot
If that gives an error, use... bcdedit /deletevalue {current} safeboot
If you run into the password problem, enter this command and see if that helps..
net user Administrator /active:yes
