nis4, Rollback is not compatible with Linux. Thatis you wont be able to install it on the Linux OS so as to access the "Windows snapshots" from it.
However, i believe their is a method in which you may still have a Rollback Windows system and Linux system in a dual boot confuguration. The thing to remember is that when booted into linux, DONOT, I repeat, DONOT access the HD containing the Windows System with Rollback installed. Modifying any files on this HD while Rollback in not running will corrupt the data on the HD. This is because the Rollback Drivers are not running whilst in Linux so any writes to the Windows HD will overwrite Rollback snapshot data creating a real mess.
Now how to set this up. I've never actually used Linux. So i cant really give advice on this. Hopefully someone else in this forum is already doing this and can advise.
In the meantime, if your familiar with VM's (Virtual Machines) then you may want to try dual booting a Windows and linux system in a VM and installing Rollback on the Windows OS and see what happens. This way you can try different methods until you have success, giving you more confidence when you try it on your real system.
If you have any more questions please ask and i'll see if i can answer them.
