You need your Windows 8 install disc to "fix mbr"

Your problem is the result of doing things backwards. If you wanted to eliminate Ubuntu and were using its bootloader, you would first need to get the windows to work. For that you will usually (always?) need and installation CD/DVD and use the Repair option. There are numerous sites with explanations of this process. Almost all the boot files are on the boot partition (if you have one) or on the system partition which you deleted. This applies to windows as well as Linux.

You might try the windows recovery CD from neosmart at the link below:

Looked at that, really looks nice, but sadly it is commercial only, you have to buy it before you try it.

So, if the OP has a Windows 8 installation DVD he can use that, of he doesn't have one he can download a 90-days trial version here: http://msdn.microsoft.com/en-US/eval.../jj554510.aspx

Another commmon problem is when the grub error is on a netbook style machine that came preloaded with win7/8 and the mfgr doesn't provide an install or recovery disk and the machine has no CD/DVD drive. In this case, a bootable windows usb is your only option besides a manual grub repair. This article could help http://arstechnica.com/business/2009...b-flash-drive/ it contains a link to an official MS windows 7 usb installer.

mr.cracker,
if you have access to another mechine create a cd of supergrub2 and use that to boot Windoze8. Perhaps try a live disk of 12.04 and then perminantly install 'linux' to your system but beware of the shim for "secure boot" that seems to come with win8.

fred.

And a big thank you to microsoft for that. Looks like the price has doubled since then.

Thanks for everyone. I installed ubuntu again now problem solved. But now i wanna uninstall ubuntu. So how will i do safely. And am not seeing anywhere in windows partition where i installed ubuntu.
Pls give me advise to safely uninstall ubuntu 13.04.

You'll need to restore the Windows bootloader. If you happen to have your Windows install disk on hand, you should be able to use that to "repair" it (via the Recovery Console).

Once you do that, Ubuntu can be removed safely without kicking you back to a GRUB prompt.

You need to get your windows booloader in the mbr first. If you don't have an installation CD/DVD, this could be a problem. You don't uninstall operating systems, you format the partition and in your case using a windows filesystem. Also, a default installation of windows won't recognize a Linux partition and will usually show it as unallocated or free space. You would need to find and download and install third party software to do that.

First thing is to get windows on the mbr otherwise your back to where you were. Do you have the windows DVD?
