I saw this error when trying to install Linux on my Windows 7 machine. Eventually I solved it.
My issue was that at some point the partition table had become corrupted - or mislabeled. The disk was labeled gpt but seemed to be actually using a standard mbr type layout. The tools fdisk, diskpart, gparted couldn't fix the problem for me. I fixed it by booting into Linux Live USB, installing and using testdisk to analyse my hard drive and then re-write the partition table after confirming that it found all the partitions. Immediately after running this fix gparted could see the partitions on the disk. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/259540 Title: Wubi - "No root file system is defined" error -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
