HD not recognized at all if AHCI enabled in bios - please help -
Hi,
I got a weird thing going on and have NO clue whats the cause.
I want to install win7 on a clean drive.... but I cant even get to the install options, because the drive is not recognized when i turn on the machine. It stalls, even before I can get into the BIOS settings.
I need to manuallly disconnect the drive > then change back to IDE mode inside the bios and now I am able to install Windows.
The funny thing... I have a backup image of a running WIN7 installation and if I copy it onto the exactly same drive it runs without problems in AHCI mode
does anyone have an idea what might cause the problem?
another weird thing.... i already installed win7 in IDE mode and thought that maybe later, once the installation is done i could switch back to AHCI... well, same thing.... once ahci mode was enabled in the bios, the drive was not recognized anymore.
i also tried to install the chipset drivers from within windows and got a "the system does not meet the minumum requirements." after searching a solution for this problem i found out that it wont install until i have ahci mode active.... ugh.... ; )
btw: its a gigabyte ga p35 ds4
and a WD Velociraptor drive
