I consider myself very experienced with PCs (been building PC systems since 2000) - that's why I spent a week trying to figure this out! :-P lol
Seriously, we should be able to go at a good pace once Windows installer gets going again...
I removed the 2nd hard drive (it's an old 40GB one of mine) for now.
I set the jumper on his 320GB drive to Master and attached it to the black plug on the very end of the IDE cable. During POST it is listed as 'Pri Master'.
I made this the 2nd boot device in BIOS setup, with the dvd drive being the first.
I removed any attached external hard drives or USB flash drives.
Windows 7 startup went through the usual 'set country preferences' and 'accept license agreement' screens and arrived at the 'Where do you want install Windows?" screen. Here the hard drive was listed as: Disk 0 Unallocated space 298.1GB Free space 298.1GB. However at the bottom of the screen it showed, "Windows cannot install to this disk (Show details)". I clicked on 'show details' and a dialog popped up showing, "Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."
I tried a different IDE cable. Same result.
Some more info...
The 320GB hard drive was in the PC he brought to me and had been running Windows 7 without problems (apparently, for a couple of years). The only reason I am attempting to re-install is because he felt the system was running slow and that a format & re-install would improve things.
The mobo is an Asrock ALiveNF6G-VSTA. AmiBIOS P1.60.
The processor is AMD Athlon Dual core 4400+
There is 3GB of system memory.
It's now turned 1:30 am here in England, so I need to go to bed. I'll catch up with the thread tomorrow and hope that you have some ideas about where we can go next.
Thanks for your help,
Edit: I just noticed (duh!) that you're in Wales. In that case, good night.
