Ubuntu 11.10 recognizes my Windows 7 partition OK. Since that is where my work has historically been, I created links to various files and folders there. Everythingś fine until I reboot. Then the icon reverts to the generic and I am informed the link is no longer valid. I created the links by right-clicking the folder or file and selecting "Make Link" in the Windows folder, then dragging it to the Ubuntu desktop. How can I fix this? BTW, it worked OK with Kubuntu; I got seduced by the sexy Unity desktop.....
Windows partitions (ntfs) are not mounted when you reboot ubuntu. So your link is invalid.
To do automount :
Use NTFS Configuration Tool
You can install it from Ubuntu Software Center.
Follow this guide - To mount partition automatically after reboot - This should fix your issue.
