ArkaPro Posted October 5, 2007 Share Posted October 5, 2007 Hi all, I had two partitions of OSX 10.4.9 runing on the same HD. one for work.. the other as a "testing ground"... I had no problem with either of them. when I was turning on my PC I got a nice boot menu asking which OS (partition) should I boot from. a few days ago I deleted the seconed partition... ever since the system wont boot. I dont get the menu. and actually I dont know how to get to the first "main" working OS.... In windows when something like that happend - I used the install CD to "repair" windows.. and it repaired it with no problems... how can I do it in mac OSX?

Z053921 Posted October 5, 2007 Share Posted October 5, 2007 Simply open the installer, select the partition, and install the base system (install the patches too, but extra apps aren't required). As long as you don't format the partition, you can still access your home dir. - SeySayux Link to comment Share on other sites More sharing options...
~pcwiz Posted October 6, 2007 Share Posted October 6, 2007 I agree with SeySayux. Without formatting install the Main System. It will overwrite any corrupted or missing files with fresh working copies so you can boot OS X. Link to comment Share on other sites More sharing options...
thegodfaza Posted October 6, 2007 Share Posted October 6, 2007 This is not like in windows because the install dvd doesn't normally install a darwin boot-loader. That is a small subroutine run when the install is complete so you cant go to "Recovery Mode" and "Repair" "OS X". I like quotes. Link to comment Share on other sites More sharing options...
ArkaPro Posted October 6, 2007 Author Share Posted October 6, 2007 I see. Ok I'm gonna check it out and see how it works.... BTW I tried to install OSX on the seconed partition but it didnt help, after the install compled and boot still nothing hows up .. just that flicking dash... I'm gonna try reinstall those cor system files on the main system and se what happens.. - chears! Link to comment Share on other sites More sharing options...
ArkaPro Posted October 7, 2007 Author Share Posted October 7, 2007 well I just finished reinstalling OSX, and it gave me "finished with errors" message in the end of the install. I tried installing with kernel - but still same message... I think I'm going to give up and format/reinstall everything from scratch... Am I doing something wrong?

Z053921 Posted October 7, 2007 Share Posted October 7, 2007 Okay, i'm a huge linux fan, so lets do it the linux way: 1) Use 'Super Grub' (google on that). It's a 'live floppy' and it detects your systems. You can use this to get back in to mac os x and see whether you can repair the bootloader from there. 2) Install grub. Use GParted to shrink your hfs+ partition (warning: it can only shrink those partions, not grow them!) and create an ext2 partition (if you really want an ext3... but since you'll never modify nor mount it, you don't need journaling. Install grub on that partition (with a linux live cd). Check the internet to see how you need to create a menu file. You'll never need that darwin or windows bootloader again. (so it's safe from both osx and windows crashes). Here's how to install grub (open a terminal): sudo mkdir /media/mygrub sudo mount /dev/hda1 /media/mygrub sudo grub-install /dev/hda --root-directory=/media/mygrub Replace /dev/hda1 with your partition name (note: /dev/disk0s1 is /dev/hda1 under linux, /dev/disk1s2 is /dev/hdb2, etc) and /dev/hda is probably the disk your booting of, unless you've got scsi drives, then it's /dev/sda. Hope this helps - SeySayux Link to comment Share on other sites More sharing options...
ArkaPro Posted October 7, 2007 Author Share Posted October 7, 2007 Thank you very much SeySayux , but because Im pretty new in the hachintosh business, I decided to format and reinstall from scratch. I'm downloading koolkal 10.4.10 updater and going to install that shortly. But I will save your comment for a rainy day... Thanks very much!

Z053921 Posted October 8, 2007 Share Posted October 8, 2007 Reading the bashbuildins man page is reserved for rainy days. (Re)installing grub, that's something I do whenever i (re)install a new OS that ****s up my mbr (and that happened 1.000.000.000 times). - SeySayux Link to comment Share on other sites More sharing options...
