Today I wanted to boot Windows 8 but received the annoying “BOOTMGR is missing” error. Here’s how I fixed the error and now the boot manager is working just fine. This is really easy to do and you don’t have to reinstall Windows 8
Tip: If you are on Windows 7 you should read our tutorial how to fix bootmgr is missing in Windows 7
First, we are going to insert our Windows 8 DVD. You then have to change the boot order in your BIOS so you can actually boot from the Windows 8 DVD. If you don’t know how to get into the BIOS, please read your motherboard manual.

It’s usually the DEL key to get into BIOS. In there you can mess up a lot of stuff, so please be careful and read the manual how to change the boot order and move the DVD drive or USB device with your ISO to the first spot, so it will ask you to boot from DVD when you start your computer.
