I have dell l502x laptop.

Specification:
I5-2450 Hdgraphics. 3000
Gtx 540m 2b card
6gb ram
120gb ssd

Using the unibeast i installed mavericks by creating 1 partition(GUID) only

Installation didn't required any special parameters.
After installation I installed the boot loader and some basic kexts.

But when I try to boot without unibeast drive I'm getting 'operating system not found' error from bios.

I tried switching between UEFI/Legacy but didn't work.
Boot priority is set to HDD only
Data operation also set to AHCI.

Tried marking partition1 as active by booting with unibeast again but no use.

I'll appriciate any help. Thanks.

Your BIOS probably doesn't like there not being an active partition. See here: http://www.insanelymac.com/forum/to...-your-partition-active-using-fdisk-in-macosx/

Dump all the boot records and check for active partition:
Code: 
sudo dd if=/dev/rdisk0 of=/tmp/mbr count=1 bs=512
xxd</tmp/mbr|tail
sudo dd if=/dev/rdisk0s2 of=/tmp/pbr count=1 bs=512
xxd</tmp/pbr|tail
sudo dd if=/dev/rdisk0s2 of=/tmp/pbr count=2 bs=512
xxd</tmp/pbr|tail
# all of above should end in 55aa
sudo fdisk /dev/rdisk0
# mac partition should be marked with '*'

It all looks fine. Make sure you have legacy boot enabled, secure boot disabled. Make sure you have BIOS set such that booting from HDD is ok.

Some BIOS implementations don't support booting legacy to a GPT partition. For example, my desktop board does not support it unless UEFI is enabled. There are lots of tricks:

- creating a single FAT/NTFS partition for force a hybrid GPT/MBR partition scheme
- installing the bootloader to the EFI partition
- converting the disk to MBR
- installing the Windows PBR on a small NTFS partition and setting it active

But if your laptop has UEFI capability, you might consider using Clover UEFI.

Thx .
I tried installing boot loader into ufi partition. But unfortunately it didn't work.

I tried installing using clover as the tutorial says in tonymac website. I created both UEFI clover pen drive and legacy clover pendrive. But I couldn't get boot using that pen drive in both occasions.

Currently I installed using unibeast drive ,after booting to HDD , I installed clover boot loader. This methods works but really not sure if it is a right way.

Clover requires careful configuration.

For using Clover, I suggest you read here: http://www.tonymacx86.com/hp-probook-mavericks/112383-guide-install-mavericks-clover-bootloader.html. Filter appropriately as some information is HP ProBook specific (omit HPFanReset.efi, for example).

Clover is definitely good , it installed everything me doing nothing :)

This is what i did so far

1)installed OSX using unibeast .
2)Installed multi beast and boot loader didn't work. so i installed clover on top of multi beast.

Other than that i didn't change or install anything. but everything seems to be working.

1)WIFI is working
2)Intel graphics HD 3000working
3)GT 540M is detected with with 1GB instead of 2GB(not sure how osx uses graphics cards)
4)Touchpad is working with multitouch
5)Brightness controls are working

Im not really sure, is this the way it is supposed to work or not.

One more thing i can't get rid of clover boot loader from bios. changed HDDs and flashed different bios also.
