iDeneb v1.5.1 Booting

Ok 2 things!

My internal hard drive for some reason wasnt detected by Disk Utility and hence I decided to install the OSx on my external drive! The process went successful, but it doesnt boot from my drive even though I changed the boot order and made the USB drive first!
So, someone told me to check the UUID and type
-v boot-uuid=(UUID HERE)
and this worked!!

So my question is do I have to do this everytime I have to use OSx? I pretty much wana use only osx and not windows 7! Because if its this, its prety much useless since it takes about 5-10 mins just to go on the login screen of osx!
Also, i read a few places that you could change your hard drive from AHCI to Compatibility Mode by going into system setup! and when I go into system setup i dont see any option like that! (f10 says setup for me). All i can change there is the date, time, see the diagnostic log and change boot order options.!

Also after the installation and restart, shouldnt the configure chameleon open up itself? I selected v1 from the installation disk!!

Is there any way I could see my internal drive in disk utility because I want to install it onto my internal drive so it boots automatically! Or if not, how could I boot directly from my external HDD and not going through the pain of entering UUID number everytime!

Sorry for a lot of questions

I really hope to get it answered here!
Thanks a lot for your time!

Modify com.apple.boot.plist
You can edit com.apple.boot.plist via Terminal. Open Terminal and type the following:

Code:

sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

Press Control+X to exit then press Y to save.

You can alternately make a copy of this file on your desktop, edit it and then drag it back into the folder. You will have to enter your password to authorize this. Make sure the application you edit in is set up as plain text or you will have problems.

com.apple.boot.plist Syntax
The file looks something like the following:
<dict>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>-v</string>
<key>Timeout</key>
<string>5</string>
</dict>

The Kernel key sets the name of the kernel you want OSX to load at startup.
The Kernel Flags key sets boot-flags to be automatically entered at startup.
The Timeout key sets the amount of time given for your to press F8 and enter options.

If you want to add more than one item to Kernel Flags you will want to leave a single space between.
<key>Kernel Flags</key>
<string>-v boot-uuid=CC3DCCBD-1CF3-3FEE-8D50-625375FEBF3D</string>
If you want to remove all boot-flags then it should look like this.
<key>Kernel Flags</key>
<string></string>
