dual boot win7/win10 wont boot to win7 anymore +BSOD "memory managemen
My pc specs * asus z97-p motherboard * intel i7 4790 cpu * bequiet 630w psu * 8gig corsair vengeance ram * samsung 850evo 250gig ssd (win 7pro 64bit drive) * sandisk ultra II ssd 128gig ssd (win 10 drive) * 2x crucial 500gig bx100 ssd (data drives)
i recently rebuilt this into a new case and it had been working fine. Mainly using the win 7 os but more recently using the win 10 os more and more. The way it has been working is that win7 is the default boot and I have to hit the delete key on startup to select win10 to boot from.
today I was on win 10 but needed to reboot to 7. Upon doing so I hit this message:
Secure Boot Violation The system found unauthorized changes on the firmware, operating system or UEFI drivers.
It then gave me the option to boot to win10 as it is the next boot option on the list. Win 10 is now giving me the blue screen "memory management error" although I have been able to get into win10 after some more rebooting.
I ran SFC scanner and it told me that there were some problems that it cannot fix.
Everything is unplugged apart from mouse, keyboard hdmi to screen and ethernet cable. Unplugging the win10 drive from the mobo and switching the win7 drive to another port has not helped.
Has my ssd failed? has win 10 done an update that has caused this problem? It did update today, in fact the first error message I got was after win10 shut down, and when I booted into it again it installed some updates before launching.
thanks for any help!
