Windows 10 upgrade from Win 7 Ultimate finished & rebooted into low res. But it did work. Tried to upgrade video drivers to latest 2 versions of Win 10 Nvidia drivers. Both failed. EVGA GTX 970 SSC. Rebooted & after logo, came to black screen & stops.
Before upgrade, I should have changed video driver to generic low res version but forgot & left it on the Win 7 Nvidia driver which was NOT listed as Win 10 compliant (I discovered afterwards)
Tried HDMI Out from Nvidia card; Fail
Removed Nvidia card, selected MB Intel graphics in BIOS & connected to MB Video Out; Fail
Tried my Ultimate Boot CD. All attempts crash to blue screen. BUT..... next Win 10 boot, goes to failed startup screen & displays Advanced Repair oOtions;
STARTUP REPAIR: Fail.
REBOOT TO SAFE MODE: Fail
ENABLE LOW RES VIDEO: Fail
COMMAND PROMPT: Success I can get the dos prompt & can see files & directories but that's it.
At one point, got this error: "System Thread Exception Not Handled - wdf01000.sys"
NTBTLOG.TXT shows dxkrnl.sys is the last driver to attempt loading before the black screen; it fails to load even though higher up the list it shows it did load.
So I guess I need to remove Nvidia drivers or know where to go to change the video driver to a plain jane basic generic driver; but I have to do it from DOS.
Anyone know the locations & filenames to do the job?
