How to boot WUBI installed Ubuntu within Windows 8?
Installing Ubuntu on a Pre-Installed Windows 8 system

My Dell laptop shipped with Windows 8. I installed Ubuntu 12.10(64 bit) through wubi installer, the installer worked fine till the reboot demanding screen. But after the reboot, my laptop boots to a black screen with the problem stated:

" File: \ubuntu\winboot\wubildr.mbr Status: 0xc000007b Info: The application or operating system couldn't be loaded because a required file is missing or contains errors. "

I checked for the specified path in my c drive(windows 8) and i found the file there. Now, whats the problem. Is it the compatibility of wubi with windows 8 or something else?? Could anyone help

Wubi doesn't work on UEFI systems that use GPT disks. Every new computer with Windows 8 has a UEFI boot, because that's the only thing that supports secure boot.

Therefore Wubi won't work on any new computer with Windows 8.

It works fine with Windows 8 if you boot with BIOS, so if you upgraded to Windows 8, you likely have a BIOS board and it will work.

There's no practical workaround at this time, other than waiting for a fix from Canonical's Ubuntu installer team. The amount of effort required to switch to a legacy BIOS boot and replacing the GPT disk with a MBR partition table setup would negate the whole point of Wubi: to easily install and remove Ubuntu from Windows (for trial purposes).

Here's the bug report: https://bugs.launchpad.net/bugs/694242

can i set off the secure boot and if yes, then would wubi installer work fine?? – Mandeep Singh Dec 4 '12 at 14:36

No, even if you set off secure boot, it's still booting in UEFI mode and the disk is still partitioned with a GUID partition table, which is not currently supported by Wubi. – bcbc Dec 4 '12 at 18:06

This is an issue that I believe to have solved.

I think the problem is the UEFI/ Secure boot changes.

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!

Ben

Never set Ubuntu as the default OS when using Wubi... particularly if it doesn't boot. – bcbc Dec 3 '12 at 18:30
