Triple boot problem...

hii all. M explaining my problem in details so that u can understand it well.

1st of all let me tell you my system details. I have two hard disks one of 160 gb and the other is of 500 gb. in my one of the primary partition of 160 gb hdd i have installed windows 7. And in 1 partition of 500 gb hdd i have installed mac os x leopard. Guys i didnt used any software to feasible the dual boot of this two os properly(Also i even dont want to use). so to boot the os i need, i used to change the priority of my hdd from the bios respectively. I use this long way bcoz i use mac very rarely. Many peoples suggested me to use the software "easyBCD" but i ignored as use of this software once caused a big bang to my pc. Anyways now from that time i have left my about 30gb partition of the 2nd i,e 500gb hdd totally unpartitioned(And that will be a primary partition if i used it) and i have installed ubuntu 10.04 LTS in it.

Now the main problem starts. I have also attached a boot screen boot menu picture of my pc now.
i can use ubuntu and win 7 with very ease now but i cant be able to boot the mac. Whenever i choose to boot the mac it doesn't boot and a black screen comes and a logo use to roam around on the screen of a vga port(the same as when u switch on your monitor without connecting your VGA jack). And after all its really crazy that in the boot menu it is also showing a option to boot 64 bit mac while my cpu doesn't support 64 bit.



plzzz anyone help me telling some mannual way to get rid of this so that i can choose to boot any of the three os whenever i need. Any help will be highly appreciable... Thanx in advance..

I've always used EasyBCD for years and never had any problem, mind you I've never bothered with minority systems like Linux or Macs, my three systems are all Windows.

Maybe thats the answer to your problem. Stick to Windows, especially 7

Thanx wysiwyg for your reply. And for your kind information windows 7 is the OS which i like the most and i m totally dependent on it. But i need to use linux and mac for few of other very important works.



plzzz anyone help me.... Giving me some help without using any external software.

hi see if you can find this site helpful because you are trying to boot mac i would tread carefully but this link should help its a rescue disc for grub

Thanx brianzion. But the link u provided me thats is of no use for me.

You're treading in tricky territory, multibot. This link should help, though:

You should have continued multi-booting Ubuntu via the BIOS rather than using GRUB which corrupts Win7.

Doesn't MAC have a one-time BIOS Boot Menu key so you don't need to enter BIOS setup to change Boot Order? Most other computers/mobos do.

He is saying he can use Win7 and Ubuntu, though, with ease. So I assume this means through the Grub bootloader so he somehow got that back to working.
