There is a registry workaround, here, for the resolution. Haven't tried it yet and might make the display unacceptable. I don't know. I also have the problem, was on another thread but can't find it now, that my CPU doesn't have NX turned on or it might not support it. Secure boot also not available but not worried about that.
The upgrade assistant seemed quite happy to continue though, even showing these problems.
Would be interesting if denso50 could show some pointers on what, if any, the assistant pointed out any problems prior to a successful install.
Following my last post, I decided to try and update my drivers to see if this made any difference. I promptly installed Slim Drivers but following a couple of glitches this was not much help.
However, I later purchased Raxco Perfect Updater from http://www.raxco.com/home/perfectupdater.aspx and entered the code CYBER30 to obtain 30% discount off the product price and after running this through I have managed to update the drivers and change the registry entry as earlier discussed. This has indeed opened up other screen resolution options.
When selecting the new resolution 1024 x 768, I notice that the task bar disappears off the screen but presume this is not an issue when upgrading to W8.
I am more or less ready to upgrade to W8 unless anyone else has any other observations / comments before I proceed.
Well I found an easier way to change the resolution. Too late now I know but might help others. Right click desktop, properties, settings, advanced tab, monitor and untick 'Hide modes that this monitor cannot display'. Now you can change it to anything! Similar in Vista and 7. As for NX or XD being available, I went to bios, security, but didn't find any options or mention of them. For that reason I won't be upgrading the netbook.
I can now confirm that I have successfully installed Windows 8 Pro on my wife's Acer Aspire One netbook.
I followed the download instructions from the Microsoft store and ran the program without an issue. I decided to not keep any files as this netbook is primarily used for surfing the web and therefore the system was clean with just the Windows 8 system set up on the netbook upon completion.
Initially, my screen resolution was 800 x 600. However, following an update of my drivers and tweaking the registry as previously discussed I have now managed to get the screen resolution to 1152 x 864.
