Windows 7: No Windows access and devices

08 Feb 2016   #1

Windows 7 Ultimate x64
No Windows access and devices


First of all sorry for my bad english, i'm french and i'm not used to speak english

I have a big problem on my pc
MSi update yesterday offered to make updates to drivers. when i done, I activated MSi Fast boost by curiosity, it said that my PC would boot faster.

I turned off my computer after it, last night, and I turned it on this afternoon, and no way to access windows 7:

Let me explain: there's 2 times windows 7 Because I bought a SSD will have one while now, and I installed Windows 7 on it and I have not uninstalled windows 7 on my hard drive of 1To, so I'm used to ENTER the first every time I boot my computer which launches W7 on the SSD.

The problem is: I can not do anything, my computer does not recognize any device, my keyboard does not work, my mouse, my headphone, I can not do ENTER or access to the BIOS.

When the countdown ends, the following appears:

'Windows could not start. a recent software change might be the cause of this incident.'

Here are my hard drive:
2TB (media, videos music, images etc ...)
1TB (old W7 and some other softwares)
SSD 480GB (current W7 and some softwares)

I tried disconnecting my 2TB and 1TB, and SOMETIMES the PC has recognized my devices, I could access the bios and boot from the SSD, but this is what it makes me:

I then tried to plug the 1TB without the SSD, and also sometimes the PC recognized the peripherals, sometimes not ... But I could boot from it!
I had access to windows (the old) and I went into the program files from the SSD and uninstall MSI Fast Boost

And I retried the adventure (boot on the SSD) but still the same message as above ..

It is since that MSI Update make me 5 or 6 upgrades of drivers that I have this problem.
