I have a problem with a Acer desktop that will not boot to windows 7. i have tried the system recovery disk downloaded from this forums advice Thanks I rebuilt the BCD based ob this forums advice Thanks and Now I have arrived at this screen that shows

1. insert installation disk and restart( I do not have one)
2. Choose the language
3. Click on Repair your computer


Status 0xc00000e9

Info Windows failed to load because the system registry file is missing or corrupt.

Any help is welcome Thanks
