During installation of rc2 I formatted the partition with ext3. Installation was ok. But when I tried to boot to my extisting 9.0 partition I got an error like 'could not check filesystem on hdc9' (were I installed rc2). And I got no way to boot to 9.0. This also happened during installation of beta3 and rc1. The way I worked around with beta3 and rc1 was: I formatted the partitinon where I wanted to install by Acronis OS-Seletor for ext3. Another way was: to eliminate the partition wher beta3 resp. rc1 was installed from /etx/fstab in 9.0 and mount it manually. What could be the reason? Interesting may be: Acrinis partition expert shows the partition where rc2 is installed as fully used and no free space (really there are over 3 GB free).
Any hint is appreciated. W. Kasberg
