Ok this is gonna be a tricky one. Any help will be greatly appreciated.

First I will need to explain how my computer was setup when it was working properly.

I have a ASUS M2N32-SLI mobo, AMD X64 6400+, 2 gigs ram, 500 gb SATA harddrive, nvidia 8600 gt.
I had created three partitions and was triple booting vista/7/XP. All ran with no problems and worked well.

Now the fun part.

Friday night my Vista partition became full, so I decided to shrink the XP partition and make the unallocated space a new partition. Everything appeared to go okay. I left my computer on. No reboots. On Saturday I got 4 more gigs of ram. I shut down my comp, installed ram, and then tried to boot. After the bios screen all I got was a black screen with a flashing cursor.

Now for what I have done to repair.

The first thing I figured happened was that the ram was either incompatible or was just bad, so I removed the new ram. Still the same problem with black screen with flashing cursor. So then I pull open the bios settings and reset everything to defaults. Still same problem. Next I pop in the Vista DVD and do startup repair, it finds error and supposedly repairs it. Still black screen on boot. Next I pop in the windows 7 DVD and do startup repair, it finds error and supposedly fixes it. Still black screen on boot. So now I figure it must be XP causing problems. I pop in XP disc and get to recovery console. I try to run bootcfg /rebuild but it says my harddisk has a corrupt or missing file and to run chkdsk. So i run chkdsk and it finds no errors. Try bootcfg /rebuild again no luck. Ok so now I move on to run fixboot and fixmbr. Both appear to work appropriately, so I restart. Now on boot it shows ntldr is missing. Well I copy ntldr and ntdetect.com from XP DVD to harddrive. Now on boot it says something about missing boot.ini, but then says will boot from c:\Windows. Well at least now I can boot into XP. Once I get all booted up, I have no taskbar, but I figure I should try to repair the boot.ini, so I try to replace it but I have no copy/paste. I google and figure out that this means that RPC is not running. So I go to services and try to start it but it says error 5 access is denied. I find a solution that says to boot in safe mode and change some commands but I can't boot in safe mode so that won't work.

And thats where I stand. Only have access to XP, with Vista and 7 on separate partitions. Since RPC is not running I cannot install programs i.e. easybcd to add vista bootloader.

I am thinking that I need to re-install XP and then that might work. Then I should be able to add Vista bootloader.

Please help me with this problem. If you need any other info please let me know.
