XP install on an even different drive ( pc has 8 hard drives.). (The total hardware config&software is complex, I now have 2x windows 7, one of which I managed to recover from 2 years ago, and the one that stopped working, and also a still working windows To recover is not on the same drive as the MBR/Boot selector. I have not changed anything hardware wise in the past months and windows suddenly stopped booting 3 days ago. Ntbtlog is not written, the ntbtlog I have is from a year ago when I used it out of curiosity. That does work does have them, what do these folders contain ? I mean, there is a mshci and mv91xx folder, but both do not, unlike in the working windows, contain ''Enum'' and its contents.
When comparing the registries of the 2 Windowses, what I notice is that the one that doesn't work, doesn't seem to have HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\msahci\Enum and HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\mv91xx\Enum while the one No idea how this happened, but somehow the Marvell driver has been removed. What I noticed is that somehow mv91xx.sys had been removed from Windows\System32\drivers, so I copied it from the working windows 7 to the one that isn't working.
DART FOR WINDOWS 7 FIX BOOT PROBLEMS DRIVERS
What windows repair did do is repair an old windows 7 install from 2011, where I installed all drivers now and try to use it as a comparison. Windows repair first found a corrupt msahci.sys, said problem is fixed and to reboot, then a corrupt slui, again said problem solved and reboot, but neither things solved the problem, the 3rd time it couldn't repair the problem. My hardware situation is like this (simplified):ĭrive1 on inch10r > Boot loader and a now recovered old version of windows 7ĭrive2 on Marvell 91xx in AHCI mode ( Asus U3S6 pci-e card) > Windows that refuses to boot. I have tried all suggested solutions, but I still can't seem to boot into the windows I need to be in.
