After upgrading Parallels to newest RC1 (build 3120) i was unable to boot my Windows and saw familiar message "Unable to open boot camp (...)". When i reinstalled old Beta 2 (3094) back, Windows is working again. May it be FAT32 problem? But i read that issue was finally solved. Software: Windows XP Proffesional, not activated yet, installed on FAT32 partition (24 GB) Hardware: iMac / Core 2 Duo, running 10.4.8, 2 GB Ram
