HI Everyone, does anyone KNOW how to get rid of Vista from an Acer Laptop and most importantly, how to reinstall XP or mayabe Windows 7?
ThxYou could start by giving some info. of your Acer Laptop MODEL or specs... Pre-OS Installed? Recovery Partition? Boot to the XP CD, format the drive, Install XP. Make sure you have all the necessary drivers.Just from the wording of this REQUEST you don't appear too familiar with working with computers. If you remove your operating SYSTEM without accurate know-how, you can really screw up your system.

First of all, like the last poster mentioned you can boot from the XP CD. You also have the option to purchase a copy of Windows 7 and install that. IMO I never recommend 'back installing'. Installing old, out-dated software. XP is almost 10 years old. Vista was a flop in which Microsoft improved upon with Windows 7. What I do recommend is the purchase of Windows 7 Professional version which allows the option of running in XP mode. This is priced starting around $199 USD

But it's up to you. Good luck in whatever you DECIDE.  if you really want win XP, you should make sure your computer's hardware is still being supported in that operating system.

I believe there may be manufacturer's that have stopped support for XP for one reason or another (that I don't know of)
