what's recovery-environment? i booted normal!

recovery environment is when booting and then press F8 "repair your computer" or win7 install dvd "repair computer".

So you booted normal and then the error:
File: \Windows\system32\drivers\msahci.sys
Status: 0xc000000f
Info: Windows failed to load beacuse a critical system driver is missing, or corrupt.

He is at least trying to start win7!!

PC had:
-unaccessible boot device with no apparent reason.
-bcd menu cannot be written to
-and now \Windows\system32\drivers\msahci.sys error

And also memory problems in recovery environment! I think your memory has failures.

Boot again in win7 recovery environment and select "memory diagnostics" and let it run a few hours. Post results

In case you see errors you can abort it

Why you think memory is failures? you mean for hard disk? i tried with hiron cd and mini windows with Western Digital Test Harddisk and it say me PASSED!

also i recovered all my files losted by GetDataBack. about 150gb. if memory have problem how i recover it?

i tried for Windows Memory Diagnotics Tools.
