Greetings, fellow SuSE user! :wavey: :tee:
I don't think the upgrade will allow a clean install - It will need an existing OS in-place first, so that kind of rules out most XP users as I believe 64bit XP was only for business and never got an official consumer release.
IIRC from reading the Win7 install warnings, XP is no longer supported for the "nice" upgrade that carries over your settings ans applications installed, not even if you're using the 64-bit version. That should carry over to Win8.
I vaguely recall a Win7 install procedure that asked me to put my old XP install disc (or was it the serial number) into the computer to verify ownership when installing Windows 7 from an upgrade disc. With Windows 8, you're not going to have that convenience; you must have an installed qualifying version of Windows pre-installed, or a System Builder copy of Win8. No matter what, you will not have your settings and applications migrated when upgrading from Windows XP to Windows 8.
If you have Windows Vista or 7, you'll need to have it pre-installed on your computer in order to use the upgrade disc or download (obviously for the download
). If Win8 is like Win7, if you have a 32-bit version of Vista or 7, you're not going to get the "nice" upgrade either. If you have the 64-bit version of Vista or 7, you might...maybe...it's not clear. Even Magic 8 Ball is blank.
As a rule of thumb, if you have the $40 Win8 upgrade,
keep your old Windows install intact! If you have the more expensive System Builder disc, then the rules are different.
Personally I like W7, so I don't see any need to abandon it for the latest flavour.
I'm dual booting with SUSE 12.1 at the moment and tempted to go all the way and ditch windows when SUSE 12.2 stable release is out.
As good as Linux has become, there isalways some product that comes with software that only runs on Windows or OSX. Considering that disk space is so cheap these days, I'd hold on to my Windows 7 install for those inevitable cases. IJS
