Frequently Asked Questions
Q1. Why is setup unable to create a new partition?
This error occurs when the Windows Disk Management utility is unable to read and process the partitions on the hard disk. To resolve this error you have to use third-party software like AOMEI Partition Assistant Professional.
Q2. Why is the system setup unable to locate the system partition?
Der Fehler „Setup konnte keine neue Systempartition erstellen“ tritt auch aufgrund von Hardwareproblemen auf. Wenn die Festplatte nicht mit der aktuellen Version Ihres Systems kompatibel ist, können beim Erstellen der Partition Probleme auftreten.
Q3. Warum erstellt mein USB-Stick keine neue Partition?
Das Windows-Setup kann möglicherweise nicht feststellen, welches Laufwerk ein externes USB-Laufwerk ist und welches Laufwerk ein lokaler Datenträger ist, auf dem Windows installiert werden sollte, je nachdem, wie Ihr PC konfiguriert ist und welche Hardware Sie verwenden.
Q4. Gibt es eine Möglichkeit, eine Partition in Windows 7 zu erstellen?
Um den MBR und den Bootloader korrekt zu erstellen, muss Windows während des Setups wissen, welches Laufwerk Ihr primäres Bootlaufwerk ist. Dieses Problem tritt normalerweise nicht bei Installationen von Windows 7, Windows 8 oder Windows 10 auf, die EFI oder UEFI verwenden. Darüber hinaus erscheinen einige USB-Sticks für Microsoft Windows als Standardlaufwerk und nicht als bootfähiger USB-Stick. Die Verwendung von Software von Drittanbietern wie AOMEI Partition Assistant Professional kann beim Erstellen von Partitionen in Windows 7 helfen.
