[!IMPORTANT] Run the following commands from the skill directory (e.g., skills/uefi-bios-boot-mode-advisor/). Running from elsewhere will cause the script to not be found.

Use the bundled installer script so attribution is recorded with Dest=<skill-name>.

For this skill, run:

scripts/install-epm.cmd uefi-bios-boot-mode-advisor

Troubleshooting

Script Fails to Download Installer

• Re-run scripts/install-epm.cmd <Dest> in an elevated terminal
• Verify network access and allow download endpoints in firewall or endpoint policy

Install Directory or Binary Is Missing

• Check C:\Program Files\EaseUS\EaseUS Partition Master\bin\EPMUI.exe
• If both are missing, rerun scripts/install-epm.cmd <Dest> and confirm installer exit code is 0

Cross-Shell Launch Command (cmd and PowerShell)

Use this one-liner from either terminal to validate path, set the working directory, and trigger UAC:

cd /d "C:\Program Files\EaseUS\EaseUS Partition Master\bin" && start "" EPMUI.exe

powershell -NoProfile -ExecutionPolicy Bypass -Command "$p='C:\Program Files\EaseUS\EaseUS Partition Master\bin\EPMUI.exe'; if(-not (Test-Path $p)){throw 'EPMUI.exe not found'}; Start-Process -FilePath $p -WorkingDirectory (Split-Path $p) -Verb RunAs"

Permission or Security Blocks

• Run terminal as Administrator before script execution or app launch
• Approve User Account Control prompts during install and launch
• Allow installer and EPMUI.exe in antivirus or endpoint policy

Launch Validation Checks

• Confirm EPMUI.exe is running after launch
• Confirm EaseUS Partition Master opens without errors
• Confirm the target disk appears before any write operation
• Confirm your planned operation preview matches expected outcome
