So ive been able to upgrade to windows 10 for a while now, but every time i have tried, it would start upgrading and then when my PC restarted it just goes back to Windows 8 and does not give me an error or tell me why it has not upgraded. why is this happening?
 

I get this error:
0x80073B92 - 0x20009
The installation failed in the SAFE_OS phase with an error during PREPARE_ROLLBACK operation

My PC specs are:
i5 4690k 3.5ghz
gtx 970 graphics card
250gb samsung ssd
1tb hard drive
8gb ddr3 RAM
