View Full Version : [ubuntu] Dual boot - no operating systems detected

July 17th, 2011, 03:00 AM
I'm trying to dual boot Ubuntu and Win7, and I just did a clean install of Win7. However, when I start the Ubuntu installation it merely just says no operating systems detected and my only option is to erase the whole disk. I can see the NTFS partition in disk utility but can't see anything in GParted.

I've tried to look through the forums but can't seem to find a solution to this exact problem - does anyone point me in the right direction or to the solution?

you can install ubuntu with WUBI (install inside windows ). it will not erase your win 7. you can give what ever the size you want for ubuntu parttion . its safe to use .

Most windows systems come with all 4 primary partitions used. They only think windows.

Good advice on how to handle all four primary partitions used. - srs5694
Besure to create recovery DVD(s) first. And a Windows repair CD.

Shrinking a Windows 7 partition is best done in Windows. But do not create new partitions with Windows.
