It's just a drive letter. In windows registry is an entry like:
C: \disksignature\startsector

If it finds a disk with signature disksignature and partition that starts at startsector then windows installation calls it C.

You can add disks, swap cables, and a partition before systempartition .... it stays C for that windows installation. So drive letters stay the same ... as long you don't modify the startsector so move the partition itself.

In win7 winpe (recovery environment) drive letters are different. But actually you are talking to same stuff


So windows boots from what's now called C (200MB system reserved) and windows is on E

In recovery-environment command prompt:
Code:
bcdedit/enum all
Errors? Rubbish? or readable stuff?
what is after lines with device and osdevice? unknown I assume?

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

All fine!!! That's why win7 is booting (at least try to). Windows startup repair did write to boot menu succesfully. (First it failed to save).

Many errors and strange things happen.... perform a memory diagnostics!

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.
Status: no problem detected yet
