http://ubuntuforums.org – Hi, new to the forum. I would like to have some information very important to me. I used to have my hdd in 3 partitions. C:win7 - D:win8 (dual boot) - E:storing files. I created a usb key with ubuntu 12.10 booted and choose to install. After the question that setup found win8 i choose not to keep previous os and install ubuntu from scratch assuming that ubuntu would install at (previous) C: or D:. Now after the installation i noticed that i got modified partitions. Have i lost everything from E:? Or can i browse somewhere to back my files up? Thank you very much and sorry for the rush but i' (Hardware)
