I want to install Xubuntu 12.10 on a system which has already Windows 7 on it. However, the Ubiquity installation program does not recognize any partitions on the system and shows it to me as empty. But
/dev list the partitions to me, and I can mount them manually.
From this question I tried the provided solutions, but neither the
dmraid -rE command nor running the ubiquity via
sudo helped here. According to the last recommendation, I used
boot-repair to sum up the trouble, and the paste can be found here. Obviously,
os-prober does see the Windows installation, just
I'd be very thankful for a quick help, I need the dual-boot system for work.
