first of all i know there are a hundred duplicates of this question but i tried EVERYTHING that is written on these posts and the guides refrenced by them but i havnt succeeded yet. i will try to give as many details for best diagnosing of the problem.
i just got a new lenovo thinkpad with pre installed windows 8 64 bit in LEGACY mode. i tried many installations and method but got the same error everytime:
i downloaded and installed wubi on the same partition with windows and got the "no root file system detected" on first run of ubuntu.
i installed wubi on a different partition which i created and formatted in windows and got the same error.
next, i created a liveCD with ubuntu 12.04.3 desktop amd 64 and booted after coniguring the BIOS (UEFI mode, safe boot disabled and quick boot disabled) and the installation didnt detect windows 8.
next, i tried to install ubuntu on legacy mode and the installation didnt detect windows 8.
after all installation attempts i figured from posts in this site that i should partition with "gparted". after burning and booting gparted also didnt detect any partition, it just showed 750GB of unallocated space and no partitions
any one knows what is the problem?
thx in advance.
