metalpwner Posted May 12, 2009 Share Posted May 12, 2009 I have heard many times about people backing up their old kexts(which ones?), having a less than successful update, and then successfully booting in safe mode(never worked before for me), and reinstalling all their old kexts. Could somebody give me a step by step process for doing this so when I try updating I will still be able to recover from possible mishaps?

metalpwner Posted May 12, 2009 Author Share Posted May 12, 2009 Bump, guys, I almost never get my questions answered on here, and I KNOW this is one that a bunch of people will know the answer to... If I update and it won't boot, how can I fix everything so that I try again? I hear about people trying things multiple times, or using time machine to fix it. How did they get in an fix everything in the first place if it won't boot? I just need to know how I can fix things if my system hiccups.

Best simple answer is to have either on the same HDD an OS X Main system (with bootloader installed) and an OS X Test system.......or if you have 2 HDDs, then one on each HDD (but each OS X system with a bootloader).......... You can try out updates etc. on the Test volume.......then if or when you corrupt it beyond repair, you can use Disk Utility (or Carbon Copy Cloner) to clone the Main system back to the Test volume....

Thanks so much for the reply. I don't have an extra drive atm, and I have experienced a bricked drive when trying to put osx on another partition next to windows before, and even though this is different, the idea that both could die is bad. Should I just use 2 HDD's? Or is using 2 partitions pretty foolproof?

metalpwner Posted May 12, 2009 Author Share Posted May 12, 2009 If you already have Windows on 1 HDD, I personally would recommend a separate HDD for your OS X volumes. no no no. I must have spoken wrong. I have 1 hdd with windows, and 1 with osx. I used to just have 1 with windows and tried putting osx on it, which killed both installations. THis fuels my paranoia. I am worried putting a second OSX on my OSX drive would put the original at risk. I would not be using my windows drive for this. would 1 hdd for 2 osx clones be okay? Is there a risk of both going under in a bad update? Also, how would I go about putting a clone on the same drive?

Is there a risk of both going under in a bad update? Also, how would I go about putting a clone on the same drive? If you are really worried you can do what I always do.....: 1st volume at the start of HDD is a small 10GB volume (choose a name without spaces e.g. Leopard_Boot or OS_X_Boot etc) to use as a OS X boot volume with ONLY a basic fully working OS X install from your chosen OS X Install DVD (which enables you to use its Disk Utility functions on the other OS X volumes), together with: Kext Helper b7 OSx86Tools PC EFI v9 Chameleon Bootloader Installer Chameleon 2.0RC1 Bootloader Installer and any other Utiliy software you find very useful for OS X system installation/maintenace/repair etc., to enable you to modify/test OS X updates on the Main and Backup OS X volumes without ever risking not being able to boot into OS X on this HDD....... The 2nd and 3rd volumes are equal size volumes, which for use as the OS X Main and Backup (or Test) systems, respectively.......suggest you use a size of at least 40GB for each..... The 4th volume is a OS X Data Archive volume with all your archived OS X and OS x86 software, documents files, image files, music files, or whatever you wish to archive and keep safe......

metalpwner Posted May 12, 2009 Author Share Posted May 12, 2009 I suck at googling, what is the best way to make a clone of my existing installation on the same hard drive? I have a 160gb drive with about 100gb free. How can I partition it with the disk utility to make a second partition? How can i load an image of my disk onto the new partition? How would I reload the a clone disk image if the worst happened?

You can only either reformat a pre-existing partitioned volume, or re-partition the entire hard drive space..... When setting up partitions on a hard drive using Windows, just create primary partitions formatted as either simple FAT32 or NTFS volumes depending on your version of Windows......FAT32 and NTFS volumes are recognised by OS X.....so you can then use Disk Utility to either re-partition and/or re-format the volumes using the partition/formatting schemes you want for OS X.......e.g. MBR/HFS+ or GPT/HFS+....... If you have made the 160GB drive as a single OS X volume and partitioned it as GUID Partition Table, then you should be able to resize it...... Or, you can use iPartition........ For cloning using Disk utility, see here.......as well as the Disk Utility Restore function, I also use Carbon Copy Cloner.......

I tried ipartition and the torrented versions are old, and they don't recognize MBR partition tables, which I use. I would either have to completely reinstall everything I have on here (ugh), or I need to get ipartition 3. I don't really want to buy it, do you happen to have it?

There are alternatives such as Parted magic LiveCD to consider if you want to shrink a HFS+ volume to create another AFAIK.......see here......

metalpwner Posted May 13, 2009 Author Share Posted May 13, 2009 wow, somebody does NOT want me partitioning this hard drive or something. Every program I try either doesn't recognize MBR, or I can't find it for less than 50 bucks... Any other software you know of?
