Have you uninstalled Linux or changed the partitions and ended up with the ”grud rescue” when restarting?
Well, then you are not the first one. Simply whats happened is that you screwed up your booting software.
Now what you need to do is to find your Windows CD, put it in your CD-drive, restart your computer, start the windows installation, select ”repair” (do not reinstall windows), choose ”command promt”, type in the following commands:
(If your on a Swedish keybord, which I am, use the ”-” key (to the left of the right shift key) to type ”/”)
Now, eject the CD and restart the computer.
If you are running Ubuntu and Windows on the same machine with help of a boot loader, you might run into to problem that the wrong operating systems starts when you start your computer.
There are two ways to fix this, the hard way and the easy way, I will show you the easy way.
Boot your computer into Ubuntu, go to the ”Software download center”, search for ”grub”, the first option that pops up is ”Start-manager”, install that application. When it is installad just go to ”Settings -> administration -> Start-manager” then you will find a dropdown with the label ”Default operating system”. Just select your operating system, close the window and reboot your computer.
