I received a very good question from “blackrose” in forum on “how do you install Windows XP, if one does not have Vista DVD.” Since you’re installing Windows XP on Vista, do you still need Vista DVD? The answer is yes and no. You will still need Vista DVD to do a repair on the bootloader because XP bootloader can’t be used to boot Vista.
If you own a branded computer or laptop such as Acer, Dell or HP, chances are they only provide you with recovery partition or a recovery DVD without Windows Vista DVD.
I also answered “no” because there are ways to install XP on Vista without Vista DVD to repair the bootloader. For people who don’t have Vista DVD but would like to install XP with Vista installed first, you don’t need to download or borrow Vista from friends just to use the repair feature!
There are 2 ways of doing it. The easy way and also the hard way.
Easy way is to download a 120MB ISO file from EasyBCD website. They’ve uploaded a copy of a CD that contains the contents of the “Repair your computer” section of the Windows Vista DVD. You can download Windows Vista Recovery Disc from here. Once you’ve finished downloading, burn Vista_Recovery_Disc.iso with Nero or your favorite disc burning software and boot up your computer with the CD.
The hard way is to build a VistaPE environment using the free WAIK download from Microsoft. The Windows Automated Installation Kit (Windows AIK) helps you to install, customize, and deploy the Microsoft Windows Vista family of operating systems. The WAIK is a whopping 992.2 MB in size.
Which method would you use to repair Windows Vista if you don’t have a Vista DVD? I’d definitely go for the easy way. It’s 120MB but at least it’s much smaller compared to 992MB! Moreover, I don’t need to manually build the VistaPE. In the world of computer servicing, speed is very important. That is how I keep all my clients happy :)
