SupportAssist OS recovery: Reset Fail

Blue screen issues: I boot and under Windows Boot Manager, i select SupportAssist OS recovery
No issues with Hard Drive scan ... so far so good
I select: Reset to factory settings
no back up of files Factory reset in progress

runs smoothly until it reaches the Clearing Partition section
Check Partition: works well
Format Partition: turns into a black screen and says: Reset Failed!

what to do next ?
