First set the Active flag on System Reserved, then Rebuild MBR. If it' doesn't start run the 3 separate Startup Repairs.

If those steps fail, move the Active flag to the Win7 partition to try both procedures again.

Do you have Product Key on COA sticker?

YES! it's include license key. i set active flag on system reserved and then rebuild MBR and no load windows!

File:\Windows\system32\drivers\msahci.sys
0xc000000f
Windows failed to load beacuse a critical system driver is missing or corrupt.

Would you please acknowledge you followed ALL Of the steps given and not just the first one? You have not yet replied if you ran Startup Repair 3 times. This is getting to be ridiculous - I must have asked you five times.

There is no substitute for being thorough here. You canot miss a step.

i now working for Windows 7 - Startup Repair - Run 3 Separate Times
just i have a problem if windows is fail how run Disk Management for option one?

Use Partition Wizard to set the partition Active. Then you can run Startup Repair from DVD System Recovery Options.

Run Startup Repair 3 separate times.

I used PW and active Windows 7 Partition.(where windows 7 is installed and no 200mb partition) then when boot from hard disk show error: "BOOTMGR is missing"
Press Cntrl+Alt+Del to restart

Also when Boot with DVD Installed for first time tell me need restart and fix it.
for two time in (Startup recovery option) Find Windows 7 Home premium and C:\ and next and on Startup repair. tell me need restart and fix.

still error 0xc000000f

for three time on startup repair:



i clicked in "view diagnostic and repair details"
