I just installed WIndows 7 Ultimate RTM on my machine. My hardisk has several partitions. The primary partiton is C. But it was of only 10GB, so I decided to install the Windows 7 on D drive. Everything is done smoothly except that, after the installation the i can't see my C drive. And all other partition's names are changed by 1 name previous to name..like D becomes E and E becomes D. I used to do the same previously for Windows XP...installing windows on D, and I was still able to see and use the C drive. What should I do now? Well I know, ideal case would be installing on C.. but currenlty bcoz of lack of space(all other partitions are quite full) and having no backup drive, I can't rearrange the sizes of partition for some time.
