I have managed to install both Windows and ArcaOS on a new computer. But now I have realized that, if you install ArcaOS before installing Windows, Windows changes the partition format of the ArcaOS partition from JFS to NTFS. You can see this in DFSEE. The data partitions are unchanged. Now I have got a JFS partition which is marked as NTFS. Does anyone know how to correct this?
Reinstalling ArcaOS will work, but I hope there is a more easier way. At the moment, I cannot start ArcaOS at all. When starting via ArcaOS USB stick, I see the C: partition, but I get an error message when accessing the data, because OS/2 cannot handle this file system. The Airboot menu OS entries are no more correctly assigned: When selecting ArcaOS, the second Windows installation runs, the first Windows installation is OK and the second Windows entry ends in an error message "no OS found". I know that when reinstalling ArcaOS, the oder problem disappears, too. I made no partition entry backup with DFSEE.
