Having just got hold of my copy of Windows 7, I decided to install it on my rather long-in-the-tooth PC. It is a 2.5Ghz P4 with only 1.75GB of memory and a 40GB hard drive… OK stop laughing there at the back… But it works for me as I am mainly an Apple Mac user…
Anyway… I stuck the Windows 7 DVD in the drive and booted and I got this strange error: “Cannot boot from CD – Code 5″
This is quite odd as other DVDs boot fine on this machine including Windows Vista. After a bit of research I discovered that something changed in the boot loader for Windows 7. This error is mainly seen on computers with older motherboards from companies like “AsRock” or “MSI”.
There are several different solution posted on the Internet including amazing ways to burning a new version of the Windows 7 DVD with the boot loader from a Windows Vista DVD… But I wanted a quick and easy solution and here it is.
In a nutshell what you need to do is boot from a copy of the Ultimate Boot CD and use Smart BootManager to boot the Windows 7 DVD.
Step by step
- Download the Ultimate Boot CD.
- Burn it to a CD (see the tutorials if don’t know how to do this).
- Insert the Ultimate Boot CD in your DVD drive and boot the PC. Of course you need to make sure your BIOS is set to boot from the DVD and not the hard drive.
- In the Ultimate Boot CD, go to Filesystem Tools->Boot Managers->Smart BootManager
- Once the Smart BootManager is loaded, take out the Ultimate Boot CD and put in your Windows 7 DVD.
- Now scroll down to CD0 and hit ENTER.
You PC should now boot from the Windows 7 DVD without any problems.
