Have seen a problem whereby Windows Live OneCare auto Tuneup (you can't turn it off), seems to destory the Acroniss OS Selector boot sector. Each time it is run, the next time you reboot, Acronis cannot find the boot sector to boot from. You have to re-install the OS Selector and then everything is fine. The last time Tuneup was run (March 1) everything was fine. Since April 2, this is not the case. Is there anyway to protect the boot sector for Acronis so that WLOC (Windows Live One Care) does to destroy it? Does this only occur when you cancel the Tuneup in progress?
