Need help on this GPT error.
Last time, I'm dual booting Windows 7 and Ubuntu 12.10. Both we're working except for the NVIDIA optimus which is not detected on Ubuntu 12.10.
As for curiosity, I tried triple booting with Sabayon as the 3rd OS. Installation of Sabayon was successful, booted to Sabayon and update then after restart, problem arises. Can't boot to Windows, can't boot to Ubuntu, can only boot to Sabayon. Other problem on Sabayon, after update, wireless stopped working, LAN stopped working and there's no way I can connect to the internet. So I decided to just reinstall everything.
This time, I installed Windows 7 and was successful. Tried to install Ubuntu again and failed. I can no longer install Ubuntu alongside Windows 7.
This time, on installing Ubuntu, I get an error about GPT.
And after pressing YES, partition shown as empty. No windows is detected with gparted. Same with NO, outcome is still the same. No windows partition is detected. As if hard disk is empty.
The same error above occurs when I tried to install Ubuntu via WUBI.
Weird. It works before but this time, it won't.
Anyone have experience something like this? Can anyone share their experiences and how they fixed it?
