Title
DL appliance stuck with a Black Screen after logging into Windows after a RUU upgrade -
Description
After upgrading the RUU on a DL appliance, when logging into Windows you end up with a black screen and you can't get much further.
Processes can be started from Task Manager but the desktop user interface won't appear.
-
Cause
The FTBU was incorrectly trying to run as part of the RUU upgrade, on a system where FTBU had already been performed. This is normally done when the DL appliance was initially setup. -
Resolution
Solution 1:
- CTRL+ALT+DEL,
- Open Task Manager
- Open a New Task, type Regedit
- Locate the below registry key
- HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Appliance or for the legacy RUU versions HKEY_LOCAL_MACHINE\SOFTWARE\Dell\Appliances\DL\
- Export the branch
- Set the value of FTBUConfigured=true
- Set the value of ShowSetupWizard=0 (if it doesn't exist create it as DWORD 32 bit)
- Reboot the DL appliance
Solution 2:
- CTRL+ALT+DEL
- Open Task Manager
- Open a New Task, type Regedit
- Locate the below registry key
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell
- It should be: C:\Program Files\AppRecovery\FTBU\ftbu.exe or for the legacy RUU versions C:\Program Files\Dell\Appliances\DL\FTBU\ftbu.exe
- Export the branch
- Change this to explorer.exe
- Reboot the DL appliance
NOTE: if the issue persists and the appliance was joined to the Active Directory Domain, please sign off from domain account and try to login with a local administrator, since some domain policies or damaged user profile could be causing this behavior as well.
