Without any warning at power up, the screen displayed "Start up" and clicking it sent into a repeat loop without any starting computer normally. After many attempts to clear the loop, I am now left with the only option of after boot shows [Prepare repair] finishes, then screen shows [Choose an option], [Use Device] [UEFI SanDisk] [Return to Windows]. Clicking [UEFI SanDisk] options and waiting a few minutes, the computer opens and functions normally. The Welcome icon is no longer part of the start up. As mentioned by me, a real nasty this one, never experienced the likes in my over forty years in computing. Has any other member experienced this? I certainly hope, someone can help as if not, trouble remains with present start up.
Help will certainly be most appreciated.
