1) I cleared CMOS. Reset BIOS defaults. --No change.
2) In Googleing AHCI, it appears that my NIVIDA equiped motherboard does not require this. I can find no way to do what you suggest here either.
3) Booting from cd drive.
4) If I run win xp in SAFE Mode or SAFE mode with network, then place the win 7 upgrade disk in the cd drive, xp opens the win 7 upgrade as it should. I can not install win 7 ( both tries fail to properly install win 7.)
Thanks for these suggestions.
Any more? Anyone?
