Server does not boot after resizing volumes

Hi,

I've used Acronis bootable media to do two things:

1. I moved the volume D to other disk (C and D were in the same disk) and then restarted the server and all was OK.
2. As at that moment I had unallocated space (in both disks) I decided to resize both volumes, and again used the bootable media and resized C and D using all unallocated space, restarted the server and did not boot, only appeared black screen, no error message, nothing.

I'm using OS Windows 2003 Enterprise Edition (32 bits), My server is HP Proliant DL 380 G6 and I have two disks array, the first has 4 HD 300 Gb each one (in RAID 5) and the second with 4 HD 142 Gb each one (in RAID 5)

What could I do in order to get the server boots again?

Regards,

Carlos
