I have an acer 4620z and i have vista and i was trying to install xp however during the installation i got a problem described by many as "hardisk cannot be detected make sure that your hardisk is properly plugged in" something like that. There was an advice to change AHCI to SATA or disable the AHCI. my question is Where in BIOS I can disable the AHCI. There is no option like that.
Any repsonse will be much appreciated. thanks and more power
im not sure if this applies to all registries, but the hard disk capacity is limited to 160gig if you wont enable this:
(im not sure if its 160gig, the size limit, but yeah hard disk capacity is limited, to change that follow the steps)
go to REGEDIT (start>run>type"regedit")
then..
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/atapi/parameters
at the parameters, click the windows space and select "new" then "DWORD VALUE"
change the name of the dword value to "enableBigLba"
double click that value(the enableBigLba) and change its value data to "1"
leave the base as hexadecimal
then reboot
then try installing the windows again, if the same problem appears your hard disk(where youre installing the operating system) might be not support by your motherboard.
anyway try this thread
http://www.techspot.com/vb/topic27534-2.html
you can see my post there at the second page, something similar to your problem
iam worry about my database gone when i change it...
Cheers
Disabling the 'native sata mode' worked for my hp laptop
thanx
we've been searching for 2 days to find a solution :).
how a little change in the bios can make everything work :)
greetings from belgium :)
I read the entire thread because I have a similar problem after installing win 7 everything was fine but right after I installed the Zone Alarm suite just like I had it before formatting. I rebooted and everything was fine until I clicked on the general tab with Zone Alarm. Boom, I got a blue screen and since then I have been trying to fix this and no luck. I got a Stop: 0X0000007B (0XF78DA63C,0XC0000034,0X...). Now when I try to follow your advice to chage the BIOS setting I just cannot find it. I do not find anything that talks about hard with option of sata, etc My PC does not even load win, it gives me a DOS message: No bootable device-- insert boot disk...
I booted from win 7 DVD to reinstall win but my hard drive is not listed in the list. Please help..
Thank you
