Operating System Not found. Installtion problems.

[aBall]

I am trying to get this working and i have tried many methods. and i always get the same error.

 

Operating System Not Found

 

Its a Alienware m5790 17" with Intel Core 2 T7200 2.0ghz

Ati X1800 2gb RAM.

Mother board is according to Intel's utility

Intel 945GM/GMS/940GML or Intel 945GT express

 

so i am stuck. i have look at soo many guides but unless i have a gigabyte board it seems im in the dark. I have now searched 5 forums and I am just trying every method i can come up with. my biggest problem is i find a guide and i cant download the files from rapidshare it just takes me somewhere else. or i find one way and its totally different from the others.

 

i just need some direction. i have a USB drive, I have restored my Retail Snow Leapord Disk onto my usb drive and i have downloaded so much {censored} that i just deleted it all because it wasnt making any sense. some guides say i have to play with the files in terminal others just say put the dmg of the install disk on a jump drive and install it. well i cant get to the installation part. my computer turns on and before it boots it just says Operating system Not Found. and i cant move forward from there. my computers bios wont allow me to change my AHCI settings. but i saw some where that i could down load a kext file that made it so i didnt have to do that or somethin but i cant find it now.

 

 

i just need a little direction, some advice on something to try.

 

thanks

this will sound stupid but works for me....

google "iPortable Snow OSx86"and download it (it is a mac image file)

Now you need Windows and VMWARE to set up OSX in

-nothing fancy - just need basic fucntionality

---unless you have access to another OSX machine then skip to bottom (COPYCAT)

Setting up VMWARE with OSX can by strange because you need DARWIN.ISO to get it to boot and during setup you might need to boot with busratio=20

Anyways there is a ton of info on doing that

 

Once you get OSX running or access to another OSX machine, use COPYCAT to restore that image (IPORTABLE) to your USB drive....takes like 3 minute

 

Once it is done, IPORTABLE shoudl be seen on your desktop

Copy COPY CAT and iPortable Snow OSx86 to the usb drive

 

Take USB drive to your computer and boot from USB

*OSX should boot from that

 

Now do same thing and use COPY CAT to restore that image to your computers hard drive

 

This works for me, takes like 3 minutes to install OSX now.

*not counting the tweaking, like network cards kexts or sound or video......

 

Hope this helps

thanks i will try this. I do have an iMac running snow leapord now so i can work on it and then move all my files over.

 

i have a restored image of my retail dvd, i have been trying to put that on my usb drive and then load chameleon on there with it and go from there. but i cant seem to get anything working.

 

i will try this. while its downloading i have one more method then i will try that.

 

 

 

[EDIT]

 

well the last method i tried didnt work but I didnt get a Operating System Not Found error. just a flashing cursor. i dont know what that means.

ok well i tried iportable snow and now im trying to get g-parted but i cant figure this out. .iso doesnt work on mac and my usb drive isnt working when i boot in vista.

Boot into MacOS using your boot CD (if it doesn't work let me know and I'll send you a link to one that does)

Download files.

Open downloaded files.

Double Click "Show/Hide Files"

Open Chameleon folder.

Install Chameleon to your MacOS drive.

Copy file named boot

Navigate to the root of your drive

delete the file named boot that is there (drag and drop to trash)

Paste the boot file you copied to this location.

 

Should fix your boot problem.

 

(These steps and files were not compiled by me, they just fixed my "operating system not found" error.)
