Since the beginning of the year we have purchased a "Cisnet' computer that came loaded with Win Xp-pro media center.
Part of the purchase agreement included a "free" version of Windows vista HOME premium edition when it became available.
The computer mfgr. has delivered to me the Vista software on a disk with the Microsoft key and holograms on it. There is a condition of use that it is only to be used on the Cisnet computer that we purchased.
I have been following the many comments (elsewhere as well as CH) re people's thoughts on Vista. The consensus LEANS toward the negative side (for a variety of reasons) re Vista at the moment.

Is it possible to leave the XP-pro O/S installed on the computer and install the Vista on another partition on the same computer? Is it possible to installl the Vista on a removable H/D that is associated with the Cisnet?truenorthYes its completely possible to have to OSs.
And yes its possible to install in on the removable hard drive. that's if that drive is large enough.
Only I don't know how you can do that.
I 'll follow this topic sow I learn how I can do that.

1.While i have yet to overcome my wife's resistance to "fiddling " with her computer (the Cisnet) my natural couriosity obliged me to experiment with one of my own computers. A Sony Vaio model PCV-RXA 842.This computer and it's problems are related in CH "computer software" ""problem with Sony Vaio Desktop" .
2.Besides the generous help from the CH forum members i could not have achieved the success i have now without the additional help of 2 web sites http://www.geekgirls.com/windowsxp_install.htm & http://www.le.ac.uk/cc/dsss/docs/w2kprob.shtml .
3. I now have a 3 partition 80gb H/D (Samsung) 2 C&D as FAT32 and a G as NTFS .
4.C contains the original O/S Win98se (upgrade) that finally got the computer running again and G contains the XP-pro (corporate edition).
5. I was initially getting a freeze at the "Windows Setup" again as i did in the other post i mentioned . This was the same problem that was occuring with the original Seagate H/D. This TIME i used a suggestion in the 'www.le.uk" site to press "F5" when the option to press "F6" comes up during the boot phase. This overcame the freeze and ALLOWED me to complete the O/S (XP-pro) install to a successful result.
6.While i have NOT yet attemted an install to a removable H/D given this experience i do not envisage a problem as as long as the removeable is plugged in and recognized one should be able to direct the O/S install there.
7. In this instance i had to format and create a file sysyem on the 44gb of the Samsung H/D that was recognized but not formated (G). Once both were done it was there that i installed the XP-pro.
8. The only item remaining to declare "mission accompished" is to regain the use of the 80gb Seagate H/D originally installed in the Vaio. Thanks again to all of you that endeavored to assist me in these related issues. truenorth
