To all:
I tried an upgrade with a retail version of 8.1 on a USB stick and thought that finally I could upgrade to 8.1.
So I booted up windows 8 and stated the install process. Every thing was going fine up until the very very end where all I got was a blank screen and blinking cursor. ( same as many here) So upon rebooting I tried several repair options the only one that worked was a total refresh ( basically a clean install). I lost all my apps and all my documents on C: drive. When I inspected my device manager I found that my Nvidia card was identified a Basic Microsoft VGA and that I had a simple PCI communication device not working. ( appears to be my on-board Network port) My config is below. I am not running obscure hardware
The bottom line is: This likely a video card or motherboard chip-set driver issue that fails some check or is misidentified and as such fails(wrong driver loads) or only works as a basic device if it works at all.
I mean really Microsoft, there are working drivers in the Win 8 install that is being upgraded and the upgrade fails because of a bad driver or driver check especially a bug that it appears was identified in the preview.
Config:
(nothing overclocked)
Asus Maximus Gene V Intel I7-3770K
EVGA Nvidia GTX 760
16 GB Corsair Ram
OCZ Vertex 4 SSD 128gb C: drive
Couple of WD harddrives 1 TB each
Every USB external disconnected except mouse and keyboard
To be honest I've seen a lot of good reviews of this upgrade, reviews that promise better performance and a better user experience so I was kinda excited, but now well I am posting a reply in this forum so guess how I feel. I consider myself a power user so doing a complete clean install and then reinstalling all my software is not really a problem for me just takes time but for some of my friends this would be a total nightmare. So my advice skip this until it gets fixed, I haven't seen this much up an issue with a "service pack" since windows millennium.
(stepping off soap box).
Sorry for the rant everyone but I do feel a bit better. Good evening....
