Try going into safe mode by pressing F8 at start up. Then try using system restore to restore back before you modified the file.

i cant their is an infinite loop of startup repair

Load your windows installation disk, go into the BIOS and select your CD/DVD drive as first boot. Then try to do a system restore from there. Since you will be booting with the disk, it isn't loading windows from the HDD so you should be out of a infinite loop.

Find someone else who has Windows 7 Home Premium X64 and make a repair CD from their OS and use it on yours. Try to restore using a time before you replaced the dll. I would recommend if you are not very familar with windows 7 you not replace or delete dll files or any other system type files.
