I have Windows 8 Release Customer Preview on my laptop. I tried to install Ubuntu on it with Ubuntu Windows installer (I have always used this to install, although that was on Windows 7), it installs and asks to reboot, then immediately Windows 8 boots up.

I do not have the option to choose what OS to boot. How can I boot to Ubuntu? VM is not exactly what I would like to use, but it is an option, however a last resort. Any help?

Windows 8 uses a graphical bootloader different to that used in Windows 7 or Vista.

The answer here points out that the wubi maintainers have disabled it on the 12.04 CDs for various reasons, one of which is:

  1. ...
  2. ...
  3. ...
  4. Most significantly, Windows is changing it's boot system with Windows 8, and it's not clear how wubi will work with Windows 8, if at all.

So basically, Windows 8 is too new for the Windows Installer to deal with.

You will probably need to edit the Windows 8 bootloader menu. EasyBCD claims to work for Windows 8 but I haven't tried it.

Wubi also loses a lot of functionality you could get with a regular install if you partitioned correctly.

It's got nothing to do with the Windows 8 graphical bootloader (and here I assume you are referring to the Windows Boot Manager, not the bootloader which hasn't changed). This works fine with Wubi. It's got everything to do with the UEFI boot which uses GPT disks. Wubi doesn't work with GPT disks. Any computer with Windows 8 preinstalled uses UEFI, but if you upgrade to Windows 8 and have a MBR disk, Wubi works fine. – bcbc Dec 23 '12 at 2:11
@bcbc has provided other information regarding this at askubuntu.com/a/254355/102029 which explains why wubi does not work and also provides link to launchpad so folks can vote it up/mark as affected – geezanansa Apr 20 at 22:43

This is an issue that I believe to have solved- it is like this problem here - Dual Boot Windows 8 with Ubuntu 12.10

My suggestion (and it's only a suggestion) is to tpe "msconfig" (without the quotes) on the Windows 8 start screen. In the boot tab, see if Ubuntu is listed. If it is, select the entry by highlighting it and click on "Set as default". This should hopefully load the Ubuntu bootloader instead of Windows' boot menu allowing you you boot into Ubuntu.

Also, from the start screen type in "uefi" and in the settings option on the seach charm, click on "Advanced start up options", click on it. Scroll down to the bottom of the entry and under "Advanced start up", click Restart now. You should now have an option to change the boot order.

I know it is the same solution to another one but to me the core problem is the same- Windows 8 bootloader

Hope this works!
