And now the msahci.sys error stays?

No error 0xc000000e anymore.

You told me before... e:\Windows\system32\drivers\msahci.sys is simply not there!
Someone deleted it!

dir e:\Windows\system32\drivers

any files there?

You can try to boot and enter BIOS settings. Set SATA to IDE (sometimes called legacy) save settings and try to boot. Post results. If still problems, put setting back!

Please describe it exactly?

How much more specific do you need:

Then click on Disk 1 to highlight it, from Disk tab select Rebuild MBR, OK, APply both steps.

If this fails to start Win7 boot into Win7 DVD System Recovery Options or System Repair Disk to run Startup Repair - Run 3 Separate Times until Win7 starts on its own.

If these steps fail, change the Active flag to Win7 partition itself and repeat the steps above exactly.

If these steps fail then we have to consider the possibility your original problem was infection and attempt to disinfect and then run the repairs again. Steps here: Troubleshooting Windows 7 Failure to Boot

Since you have 3 primary partition and 1 extended one, you already have the max of 4 partitions.

Within PW delete partition 200MB (partition is not really needed)
Make 420GB partition smaller. Make it 350GB or so. There will be 70GB unallocated space then. Format the unallocated space as NTFS (quick format) and make it primary. Mark that partition as active.

Now of course apply the changes. Post camshot when it has done the job.
