Can I install Windows XP after Ubuntu?

I have not yet tried installing Windows XP after Ubuntu. But I'm sure when you installed the Windows XP the Boot setup for the Ubuntu will be lost. There are workarounds on how to restore the boot setup of Ubuntu after installing Windows XP. After you install Windows XP or before installing you must have at least the ideas on how the fix. If you don't want to read more, it is better to reformat the Hard Disk Drive. Then install Windows XP then Ubuntu.

I think it's okay. I have got two operate systems, i.e., Windows 7 and Fedora, on my desktop. They work fluently. My main OS is Win7. After installing a vitual box, I install Fedora there.

Yes you could install windows xp on ur ubuntu laptop... but the MBR will be overwrited and u will have to recover GRUB..

Yes there is no any problem. You can install windows XP over Ubutu. Because after installing windows XP you are not bale to installing ubuntu. But after installing ubuntu you are able to installing windows XP.

As all guys suggested you should be able to load XP. I would prefer formatting the system and having partitions - keeping the two OSs in separate partitions. That is how I used Widows 2000 and Windows XP.

no problem .go ahead just pay attention to the demand which XP need and which the ubantu need .then active yourself immedietly! wish you suucessful!
