hello my question is if i can install snow leopard without erase my entire hard drive where i have windows 7 in one partition and snow in the other but an iatkos version!.......

yes, jut simply use the disk utility to erase the distro version or whatever you want to do, it shouldn't affect the windows partitions operation, but you may want to make sure that you wont mess up your bootloader or anything

With Windows 7 on the same HDD as Snow Leopard, then Snow Leopard will be installed onto a MBR partition by iATKOS S3 v2..........but installing OS X will overwrite the HDD MBR with whatever bootloader you choose in the iATKOS Customise menu.........

[Polivio]

but it says that it must be guuid partitions and if i do that all my hdd gets erased

[J.B]

if you want to install to the MBR, google it, i believe the basic process includes modifying the OSinstall.mpkg to allow MBR installation

[Polivio]

i dont find any guide....can you give me one please?

Here is the relevant extract from the iATKOS S3 v2 readme:

- GPT (Guid Partition Table) and MBR (Master Boot Record) partitioned harddrives:

GPT is a partition table type for x86 computers which is also Intel Mac's partition table type. Its structure is different from MBR and so it has some nice features. The whole GPT multiboot procedure may not be so friendly for newbies, so they should go on using MBR, performance of the system will not differ from GPT to MBR.

MBR has a limit of 4 primary partitions (which is a must for booting an OS, however linux can boot from logical partitions by MBR) but GPT has no such thing like primary or logical, therefore you can create up to 128 bootable partitions on GPT disks. HFS+ partition resizing is only possible on GPT drives and it is such a comfortable feature. All windows series (win 3.1, win95 and win98 are MBR only) can be installed to a Hybrid GPT drive which can be easily created using OS X disk utility, just create one or more FAT32 partition(s), make sure that they are at the first 3 order and there you have the Hybrid GPT for windows installation.

New Linux bootloader Grub2 supports GPT, so nearly all updated Linux distros can be installed to pure GPT drives.

For Software RAID feature on Leopard and Snow Leopard, you must have GPT partitioned drives.

In the near future, most of x86 computers will run on GPT drives.

 

If you go to Disk Utility >>> Click on your HDD icon in the lefthand column.........at the bottom of the screen, you should see:

Partition Map Scheme : Master Boot Record

 

So, you do not need to partition the HDD, you only have to highlight your target OS X volume in the lefthand column and go to the Erase tab in Disk Utility.........then choose Mac OS Extended (Journaled) for the Format option and give the target OS X volume a new name, e.g. SnowOSX (it is best to have volume names without spaces)......

 

You will soon find out if the iATKOS S3 v2 Install DVD can install to an MBR partition (which AFAIK it does not say it cannot do in the readme.....)

 

Also from the iATKOS Readme:

 

- MBR (Master Boot Record) triple boot -

 

- Nearly all PC's work on MBR partitioned harddisks, check it with Disk Utility, if so do no touch it. If it is GPT then you need to repartition your harddisk by loosing all the data in it. Click to partitioning options, select MBR and do the partitioning.

 

- Create 3 or more partitions by using iATKOS Disk Utility or Parted Magic Live CD. HFS+ format for OS X target, Fat32 (ms-dos) for the others. OS targets must be one of the first 3 partitions creating with Disk Utility.

 

- Add boot flag to Windows or Linux target and install the operating systems in any order you like.

For windows, make sure the windows target disk is the first preceding disk by your BIOS, unplug the other harddisks if needed. This is a general windows issue.

For linux, do not install linux bootloader to MBR, install it to linux root.

 

- Boot iATKOS S3 DVD and install OS X to target as usual.

 

- If Windows fails to load then you may need to repair Windows (win7 or vista) (mostly you will not face this issue): Add boot flag to Windows partition, boot Windows DVD, select repair, add boot flag to OS X partition.

 

- You can also add boot flag to Linux partition to use Linux bootloader for multiboot manipulation if you want to.

 

Now you have triple boot on MBR.

 

Note: Adding boot flag to MBR partitions: Boot Parted Magic Live CD, right click to partition, select flags and click to boot.

i allready installed iatkos what i want now is to install the retail version but it says that i need guuid partitions and if i change the partitions tu guuid all my data will be erase because of the change of this......thanks for response

If you want to install the Retail version on an MBR HDD volume, then you need to install from a patched Retail OS X SL DVD image.........the simplest way is via a USB flash driver installer...........you can follow my Snow Leopard Retail Install Guide for nForce chipset MOBOs if you wish (except you will not need to use AppleNForceATA.kext)........see Part A, then B, then C and then E.......
