For both RP and RTM, unlike CP, Windows 8 *doesn't* support all systems even though the minimum stated base hardware requirements are exceeded. On a Dell DXP061 series with: an Intel® Core™ 2 Duo processor, 4Gbs of memory and an ATI graphics card, no matter what configuration options, BIOS or peripheral changes, Windows 8 RP and RTM is a dog that just don't hunt. Windows 7 runs without any problems on the setup. Both Dell and MS confirmed that MOST systems will run Windows 8 and any more than five years-old, even if it exceeds minimums, may NOT work. Anyone else having similar problems?
What sort of error are you getting when you try to install? If it's saying something about unsupported CPU, see if you can enable DEP/NoExecute/Execute Disable Bit in your bios as Core 2 Duo's SHOULD support it.
Windows 8 RTM installs and runs for awhile, but it goes down with a different error each time. As posted, neither company will provide a fix and it was annoying as CP installed and ran fine.
Fatal errors include: -KMODE Exception Not Handled Kernel level probably BIOS related -System Service Exception Again very low level Ring0 function calls -0xc0000000f Again low level below Ring2 All these errors reinforce HW problems ISO hash values matched even the .iso created from the recorded DVD matched. Same DVD-R used to install on other rigs worked fine. Original files actually installed from USB or HDD after USB boot. Back to Windows 7 for this box!
Forget about dual booting in a RAID environment... at least for a while. Windows 8 eventually installed and stayed stable, but all the other OS's had to likewise be re-installed as well. AHCI is the problem here and until Windows 8 specific drivers ship these problems will persist.
have you checked, that your RAM memory works correkt? Seemingly random low level BlueSreens moastly result from either a "halve" faulty Ram memory or "halve" damaged HDD. Even Win 7 sometimes crashes on an Install or sometimes only later with this hardware defects. That Win 7 runs seemingly without crashes on a "halve" faulty hardware isn't a "sign" for correct working hardware. Win 7 (also Vista) is very resiliant if you can install it on a correct working hardware and then the hardware is in the beginning of failing. I know this from experience of supporting PC.
The DRAM was the first check. All are OK. Again, the problems were multi-faceted as a combination of dual-booting several MS OSs with pseudo RAID. Either no Win8E or without AHCI and other OSes or RE-INSTALL other OSes without pseudo RAID. Had to spend almost a day sorting out these issues.
