How to install within one disk

Hi all,

 

I have a 100GB hard drive in my T60 with 3 partitions. One for 30G is now used for Leopard. I have another two with 30G, 40GB. I am thinking about merging the 30G+40G to be a 70G disk for Snow Leopard. I can go with a fresh install, how can I achieve so? Any link? A lot of tutorials talk about dual hard disks installations. However I have only one disk with two or three partitions.

 

Another thing is, if there is gonna be a iPC 10.6.X release pretty soon, I can also wait for some extra time. I have a real MAC to play with for the time being.

 

Please advice in all ways!

 

Thank you!

Surely you can do it with a single physical disc. What they mean by dual hard discs is well, God knows what they mean... Here is the basic idea: You copy the retail DVD to an extra partition (not necessarily to a disc) as an image. You use that image to install the OS to an installation partition (again, not necessarily to a disc). Here are details:

 

  • Boot your machine with Leopard, run Disk Utility.
  • Partition your free 70 GB space into two: 60 GB and 10 GB in that order (if you really want to have 70 GB Snow Leopard at the end, i.e. don't partition into 10 GB and 60 GB).
  • Dump the retail DVD image onto the 10 GB partition using Restore in Disk Utility. (Even if you have the retail DVD, you cannot install directly from the DVD to an installation partition at my best knowledge as of today, i.e. this 10 GB is a necessary partition to install the Snow Leopard.)
  • Install v10.6 onto your 60 GB partition using the image sitting on 10 GB partition from your running Leopard.
  • Once you have a running Snow Leopard, remove 10 GB partition and resize 60 GB partition, which has the OS, to 70 GB using Disk Utility.

 

However, I recommend to use two partitions for the Snow Leopard (and any OS for that matter): one for the OS itself and the other for user home directories. As you will experience, you will end up copy your home directory to the new OS partition and set all the tedious preferences again. Simply by putting user home directory on another partition, and pointing to it as your home directory once a new OS installation is done, you don't need to copy nor set the preferences. Also by doing so, you can share your home directory under Snow Leopard and Leopard at the same time. If you opt to do this, you need not two but three partitions: one for the OS, another for the user home directories, the other for the temporary space on which the retail DVD image sits.

 

Good luck.

Thanks very much!

 

However, I am still a little confused about which partition to boot after installation of Snow Leopard.

 

Say, I have Leopard now installed on partition 1, and I am going to have Snow leopard installed on my partition 2 (70GB) as you mentioned. I guess during installation, I have have to use some command to change the boot section and point the darwin loader to the snow leopard partition.

 

So, my question is, can I format the current Leopard partition 1 after installation of Snow Leopard and use partition 1 as my user homefolder. If so, I do not have to format my 70GB partition to be 60GB+10GB. Please advice me how to achieve so, general idea or a link would help.

 

Thank you!

I did it one one HD with 2 partitions guid on my gigabyte ud3p...leopard 10.5.8 (used ipc 10.5.6 plus combo update to 10.5.8) on one partition, snow on the other. So it is possible...also i never even restored the sl10432 dmg image with disk utility to an empty partition...i ran the osinstall.mpkg straight from the mounted dmg in leopard to my empty snow partition. (make sure to customize installation and deselect printers and languages)...i installed chameleon rc1 using this app x58_Mobo_Patch_Installer_Beta_muzzle.nl at http://www.snowx86.com/downloads/ after it finished installing to both my leopard and snow partitions...then i think i patched dsdt and added some kexts...sorry cant remember exactly...but i know i used the x58 file after numerous failed snow installations....and that worked for me using just 1 hd...look here too...ignore my first few posts....just read from jymboches post down...theres some pics too there that might help...i dont know if it is all necessary but it worked...

The answer to your question is yes, but I would not erase the working Leopard partition for a while (say until v10.6.1 is released) just to have user home directories. And the 10 GB (as in your "60GB+10GB") is not for the user home directories but a temporary space that holds the retail Snow Leopard image, which you can erase and merge with 60 GB once the Snow Leopard is installed. (As dparada78 pointed out, you may not need this 10 GB after all.)

hi I also want to install snow on the same disk as my 10.5.3 install...

I tried following some guides but I am confused about the bootloaders...

 

I installed chameleon 2 rc2 to the mbr of the disk and put the theme files etc in the extra folder off my 10.5.3 partition...

 

chameleon does find the install of snow leopard on my second partition but I always get a kernel panic... I tried different things and somewhere it is suggested to install chameleon 1 to the snow partition...

I did this but somehow nothing changed at boot..

 

I still get Chameleon 2 and when I select the second partition to boot it just gets a kp again ( I don't see anything about chameleon 1 (should I?)...)

 

 

Could someone explain to me how those bootloaders work or tell me where I can get information about it?

 

why do I have to install a bootloader on the snow partition?

 

thx
