Windows 8 (64-bit) System.I downloaded Ubuntu and every thing going well and started installing it. Ubuntu is successfully installed and rebooted but then I get an error during Ubuntu's boot.The error is:

Starting Windows didn't succeed. The reason may be changing software.
To solve this problem:
1. Insert installation disc of Windows and reboot pc
2. Choose language settings and click Next
3. Use Repair
If you dont own this disk contact with the administrtor.
File: \ubuntu\winboot\wubildr.mbr
State: 0xc000007b

Here i read for many users have the same problem that i have,I think Ubuntu is not working on Windows 8 (64-bit) System

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

You tried to use Wubi didn't you? Wubi does not work with Windows 8 and never has. Probably never will. Therefore, support for Wubi and Windows 8 isn't available. – Thomas Ward Sep 10 '13 at 21:56
Here Ubuntu sit said "If you have a PC with the Windows 8 logo or UEFI firmware, choose the 64-bit download. " But this was wrong,because Ubuntu 13.04 64-bit & Ubuntu 12.04 LTS 64-bit both of them are not working on Windows 8. – Lion Iron Zion Sep 10 '13 at 22:06
Because Wubi does not work with Windows 8. Wubi support was dropped during the 13.04 dev cycle. Did you try and use wubi? The error you're getting suggests that. You'll need to use Windows Boot Repair, either from a Windows Disk or a repair partition, or using media from the manufacturer, repair the Windows bootloader, then remove Wubi and install alongside Windows 8 using answers here, or use VirtualBox within the Windows environment. – Thomas Ward Sep 10 '13 at 22:24
Mostly correct. But the issue with wubi is not Windows 8 but gpt partitioning that all pre-installed Windows 8 systems have with UEFI secure boot. If you manually install Windows 8 in BIOS mode then you can use wubi. Ubuntu 12.04.2 and later all have secure boot, so they will work with Windows 8 and secure boot systems. But newer versions may have updates to work better with some of the very new hardware. – oldfred Sep 11 '13 at 4:19

As explained by Thomas and Lion, Wubi cannot be used on Windows 8. But there are alternatives if you just use Ubuntu casually and don't want to create a dual-boot with dedicated partitions on your internal drive (a bit more complex but still pretty easy):

  • Install Ubuntu on an external USB HDD (I always have one ready to use as a rescue system)
  • Install Ubuntu on the same drive, side-by-side with Windows (see this post's answers for the steps to take.
  • Use a virtual machine like VirtualBox. You can find many tutorials explaining how to do this step by step.
