After testing Ubuntu 11.10 (64 bit) by booting it from the CD, I unfortunately decided to install it on my pc. On my pc I had kept on each hd and the ssd as well space enough for other partitions. I used the offered option to install Ubuntu alongside with Win7 and ... ended up in a half destroyed system. Everything seemed to work well during the installation, but after reboot I got the mess.
During boot it does not ask me which OS I would like to choose, as it was said in the installation routine. It always boots Windows, but the Windows partition on drive d: (30% of the disk) is gone and Win7(64) instead reports a RAW partition with the the entire capacity of around 500GB. My drive C: (SSD) and Drive E:(HD) seem to be ok though. But D: was my win program drive and so my win7 installation is nearly unusable.
Is there a way to revert the installation and get my partition on drive D. back ?
