I'm not really that of a linux pro, more of a noob. But i can handle console operations. Well, this is my system:
ASUS ZenBook Prime UX31A 256 GB ADATA MX11 SSD Intel Core i5-3317U (Ivy-Bridge)
I have a fresh installation of Windows 7 Ultimate (not activated) on a 90 GB NTFS Partition on my SSD, the rest is unassigned. I want to install Ubuntu 12.04.1 from an USB Stick (no CD-Drive...) created with Universal USB Installer 18.104.22.168. However I'm not givven the option 'Install alongside Windows', and when i choose 'other' it shows that 256 GB of 256 GB are unassigned (free) Memory.
os-prober gave me: /dev/sda1/:Windows 7 (loader):Windows:chain
I also tried: sudo dmraid -rE
and: sudo apt-get remove dmraid
with no success... How can I install Ubuntu alongside Windows? Thanks very much in advance!
