The question I raise does not describe what troubles I am in, since there have been so many posts here discussing the same problem.
I tried to make myself clearer by running Boot-Repair. And here is the result:
You have installed on
sda8 a Linux version which is not EFI-compatible. It is probably incompatible with your computer. Please install an EFI-compatible system. For example, Linux-Secure-Remix-64bit and Ubuntu-64bit are EFI-compatible systems.
Hope this info is clear enough
What can I do to make this dual-boot works?
To give a summary of what I did:
- I already have win 8 on my K45V asus
- in win 8, I used Disk management to create a new partition for Ubuntu
- I burn an Ubuntu 12.04 CD and boot from it
- I install Ubuntu here
- there was a dialog showing some partition resizing but I didn't really know what it was for? (why does the installation automatically go into the newly created partiion?)
- after installation, I restarted the pc and the boot menu never shows up, but goes directly to windows 8
What's the point now?
Any comment is a big help for me
