I had Windows 8 installed on my old AMD 64 with 2G RAM.
Installation went smoothly and it was really quick (did not time it, but it is faster than XP installation) with 2 reboots required.
Almost all Hardware was recognized and functional – it looks like my integrated card reader give some trouble… but will work on it.
What I had to probably start with is that the license for that system is valid until March 8, 2012 (Is it a coincidence that this is international women day 😉 ).
And most importantly you have to plan that installation really carefully.
If you need to (witch is most probably the case) keep your old OS (XP/W7) you need to:
- Create new partition for Windows 8 – this can be done with live CD like partedmagic or similar tool (windows disk management).
- Choose that partition as destination during windows 8 install – you need to choose Custom as install method.
- Continue installation
- After installed go to system properties -> advanced -> startup and recovery settings and choose previous Windows version.
This procedure will show you menu on boot so you can choose what version to boot.
