The first time in my life I’ve got to remove ubunutu from a nice pc survived to 4 distr-upgrade successfully. A sad day!
Anyway, my friend asked me to do it and the “great mistake” was there… I removed the partition forgetting the boot manager… and now windows says “ups!” GRUB Error 17.
Obviously I don’t have here a Win XP install disk, only the original recovery disk of HP that does not permit me to rebuild the mbr.
I decided to write here how to solved it using the UBUNTU LIVE way (hope!)

1) When ubuntu is started, go to:

System -> Administration -> Software sources</pre>and enable the "universal" repositories.<br /><br />2) Open a terminal and install necessary additional software (<a target="_blank" href="http://ms-sys.sourceforge.net/">ms-sys</a>)<br /><pre>sudo apt-get install ms-sys<br /></pre>3) Now you’ll need to figure out what partition is the one hosting your Windows operating system.  Back in the command line, type:<p><pre>sudo fdisk -l</pre></p><p></p> <p>That will list the available partitions.  You’re looking for a partition that says something like</p><p><pre>/dev/sda1 * 1	ecc ecc</pre>You have to recognize your windows partition in order to advance...</p><p>4) rewrite boot!</p><p><pre>sudo -s ms-sys -m /dev/sda1 (o altro disco se diverso da questo)<br />

It’s not nice to say, but it didn’t work on my laptop.

Thanks a lot to ubuntulandia for his original tutorial.

I’ve got to create an ISO file of a directory (ex: yourDirectory) on OSX system. I didn’t want to install 3rd part software to do it so I discoverd this trick:

• open a terminal
• go to your location

  cd /Desktop

• type

• hdiutil makehybrid -o yourIsoName.iso -iso -joliet yourDirectory

• Done!
