I had Vista installed on C drive (which is RAID-0 600Gb partition) and decided to create another partition for Win7 installation using Acronis disk director, it restarted and continued to create new partition in the windows preload stage, however I was impatient and turned off my computer after about 1 hour of waiting. That was huge mistake. I cannot boot my Vista again on the C drive. Later I installed Win7 on another hard disk in the same computer and was trying to fix the old Vista installation but no luck so far. Currently when I log in to Win 7 and open My Computer I can see the old C disk with Vista (now renamed to D) but if I try to open it the error message appears "D:\ is not accessible" However some partition managers can browse the old files on D and with Paragon Hard Disk manager I can export all files where I want. So it means that files should be ok after failed partition creation. I managed to load Vista (after using startup recovery option) into black screen with arrow but no task manager and other response. Is there any way to fix the partition and boot Vista again? Format is not the option because there are important files and I don't have the space in other drives to transfer 300+Gb worth of data. Also there are no backups created. Any help would be welcome.
