have got the live CD for the Fedora 12, and 13, and as usual, i got it to install on a virtualbox under windows 7 and Vista host, it works fine, and i have installed it on 2 other desktops, no problem, but when i try to install it on my laptop, HP dv 6000, when i run the install to hard drive, it says it doesn't detect any hard drive, i tried to install it on a usb stick, ok no problem, i even got an external hard drive, connected by usb, and it was installed perfect, and boots great, when i put the same hdd in the laptop, it doesn't boot, and again, i boot from usb or cd, and it doesn't detedct the internal hdd with the fedora installed on it, it is a sata 2.5" and i had fedora 10 installed on the same pc, and hdd before, but no luck with fedora 12 or 13 yet, i tried to use the noacpi option, same problem, so can anyone help me?

Please test with setting "AHCI/IDE/RAID" in BIOS to different value, might help.

Thanks for your reply, but There is nothing in the BIOS setup for this in my HP dv 6000

I found out that this is a bug as reported in this link.

I added "nodmraid" while booting, and things went smoothly
