you got this from startup repair in recovery environment. Seems like memory problems.

And why coudn't bcd not be written (could be disk error also). But it could write later!! so your system start now to win7 (with crash)
And why inaccessable boot device all of sudden
And why msahci.sys not found or corrupt.

it always crashes to msahci.sys error now?

In recovery environment:

Code:
 
dir  e:\Windows\system32\drivers\msahci.sys
(does it exists?)
chkdsk/f  e:
chkdsk/f  c:
Any errors on C and E? All fixed? In case there were errors: run it again to see if errors are gone

Do this as well in recovery environment

Code:
 
sfc  /scannow  /offbootdir=c:\  /offwindir=e:\windows
or maybe it's
Code:
 
sfc  /scannow  /offbootdir=e:\  /offwindir=e:\windows
But I think the first command. It checks windows file integrity and hopefully repairs errors. Any errors? all repaired?
Run it again to see if all have been repaired

Have you made your Lenovo Recovery disks and copied out your files with your boot disk? Copy & Paste - in Windows Recovery Console

If so I would run Lenovo Recovery from it's hotkey at boot, saving the disks as backup in case it fails.

One other thing to try first is to change the active flag to the Win7 partition itself and run Startup Repair - Run 3 Separate Times.

It say "File Not Found"
chkdsk/f e:



Code:
sfc  /scannow  /offbootdir=c:\  /offwindir=e:\windows

Code:

You're using a tool there that I've never heard of, and it sounds like it messed up your system pretty badly.

Download the tool we've used to help thousands of users successfully here, free Partition Wizard bootable CD. Burn to CD using Windows Image Burner, boot it and take a camera snap of your maximized Disk Management drive map with listings. We need to see this to proceed.

If you can recognize your 100mb System Reserved partition and/or Win7 partition, you can try the step 8 here to Rebuild the MBR with PW CD: Troubleshooting Windows 7 Failure to Boot

If this fails and you still have your Recovery partition, try marking it Active to run it at boot using the hotkey given on first boot screen or in your Manual on the Lenovo Downloads webpage for your model.

If you've lost your Win7 partition use the PW Partition Recovery Wizard to reinstate it: Partition Wizard Partition Recovery Wizard Video Help.

Try all of the steps in the Troubleshooting tutorial leading up to copying out your files to Clean reinstall with the Win7 installer provided, or use Factory Recovery disks you made or order from Lenovo Support.
