No root file system is defined / can't detect os

[iSetsuna]

As with what the title says, when i install ubuntu using wubi an error pops out saying "NO ROOT FILE SYSTEM IS DEFINED, PLEASE CORRECT THIS FROM THE PARTITIONING MENU. When using LIVE USB, my OS is not detected. I already reviewed similar threads but starting a new one would be a better idea just in case the solution is a bit different.

So heres my bootscript output.

You see in the partitions results where is says 'guid partition table detected but doesn't seem to be used'?

You had gpt tables on both disks and used windows to make new msdos tables. But windows doesn't delete the backup gpt table which linux can detect and it gets confused.

Use the ubuntu cd in live mode (Try Ubuntu), install fixparts from the .deb they have on their website, and then use it to remove the gpt remains. It's enough to open the disk with fixparts and it will offer to remove it, like:
sudo fixparts /dev/sda

On another note, I would consider a proper ubuntu installation instead of wubi inside windows. The OS is designed to work by itself, not as virtual in windows.
