ntdlr is missing, stupid me messed up using easybcd now what?

solved... I took the hard drive and mounted it in a dock in a different system. Using EASY BCD and copying a random BCD file I had it reinstall the BCD, recreate the entries, which did not work, however having easybcd run diagnostics and recover and fix the MBR a few times along with rewriting each entry and crossing my fingers when I installed it back in my main system it booted fine.

I was using easybcd to alter the bcd of another computer, long story short I think I told it to uninstall the vista bootloader before loading the bcd of the other drive I was working on.

the first installed software is Vista home premium, which I'm dual booting with win7 x64. When I try to boot I get the "NTDLR is missing" message.

Is the one of the situations where I would use diskpart while at command prompt to do something?

I cant get repair to work.

by saying I need to run it 3-4 times does that mean it's normal if sometimes it says it is unable to repair the problem?

the screen where it asks you which installation you would like to repair doesn't show any installations for me, even though both win7 and vista are installed on regular platter drives.

I take it that you still have both HD installed.

If you have removed one, that may be the one with all boot files on, if so Startup repair will not work.

both are partitions of the same physical drive. Vista was installed first.

I cant seem to load the correct drivers, or they're not working. I got the original gigabyte DVD out and copied every driver file I could find for gigabyte and marvell and still cant get it to recognize an installation.

I'm using an x58a-ud5 rev 1.0 MOBO if anyone can direct me to which driver to install. Midway through one of the drivers, well actually a couple, a popup saying it has found problems with windows starting up will come up then an error message saying something along the lines of failed to change startup.
