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

Thanks!

  • is it saying that Ubuntu 12.04 x86 is not compatible with my computer? that's obviously odd :| – Shawn Le Jul 30 '13 at 07:00
  • Which option do you choose on installation pages: "alongside windows" or "Something else"? where did you install grub? However, This may help you: Installing Ubuntu side by side Windows; Please add the output of this two commands into your post: sudo parted -l and sudo fdisk -l, Run them on Ubuntu-Live mode. – mini Jul 30 '13 at 08:24
  • I chose "alongside windows". I didn't install grub coz' I thought that was done automatically during installation process. Previously, I had installed Ubuntu along win7 and the process was totally automatic – Shawn Le Aug 03 '13 at 13:25
  • Please add the output of this two commands into your post: sudo parted -l and sudo fdisk -l – mini Aug 03 '13 at 18:05
  • I added already a while! please put on some new help – Shawn Le Aug 07 '13 at 00:59
  • It is correct that the 32 bit verson is not compatible with UEFI. Only the 64 bit version works with UEFI. see note on UEFI. http://www.ubuntu.com/download/desktop – oldfred Aug 08 '13 at 04:03

You will need to use the 64-bit version of 13.04, 12.10 or 12.04.2 and from the UEFI menu boot the flash drive in UEFI mode. That way it will install in UEFI mode. You will also need Boot-Repair, for several work-arounds for UEFI Vendor issues, and grub bugs.

The system needs Windows 'fast start up' (hibernation) and UEFI/BIOS 'fast boot' 'quick boot' UEFI settings turned off or disabled. Vital for some systems.

Use the Windows Disk Tools to shrink Windows main partition, but not to create a new partition, if installing on same drive. Reboot after shrinking so it can run repairs to its new size.

Backup EFI partition and Windows partition before installing Ubuntu.

  • this is quite troublesome and I'll take sometime to test it. Thank you beforehand! – Shawn Le Aug 11 '13 at 15:13
  • @oldfred suggest edit: "The system needs Windows 'fast start up' (hibernation) and UEFI/BIOS 'fast boot' 'quick boot' UEFI settings. Vital for some systems." DISABLED - there appears to be jester if not malicious editors kicking about – geezanansa Aug 14 '13 at 14:17
  • ReEdited to add turned off as I had originally posted. The editor add or clarified fast start up is hibernation and fast boot may be called quick boot. – oldfred Aug 16 '13 at 04:19
