NTLDR missing error after i installed mac os x

[aakash]

i get a NTLDR missing error when i try to boot to MAC OSX by this command in terminal serivces and activating the partition of mac

fdisk -u /dev/rdisk0

i m able to boot again to xp by setting the partition of xp to active.

my drive structure is in screenshot. MAC on none drive , xp on XP and vista on VISTA labled drives. no OS in C;

All i want is to boot to MAC OSX once so that i can get a feel of it. i used VMWARE to native method to install and not got any error except on startup after finishing install, to start the system i used fixboot, fixmbr in xp recoveryconsole. since then i get this error " NTLDR missing " whenever i active the OSX partition.

 

Please get me into mac.. i don't wanna multi boot now..

fdisk -u /dev/rdisk0

This command merely updates the drive's MBR. It does not set your OSX partition to active.

 

To set an active partition you will need to call this:

sudo fdisk -e /dev/rdisk# (replace # by the correct drive number!)

p (to view partitions)

f # (replace # with correct partition number)

write (answer yes to question)

reboot.

EDIT: This fdisk is to be used under OSX, ie. with your boot DVD and not from Windows!

I remember I used below commands to set partition active:

 

fdisk -e /dev/rdisk0

flag x

 

(x=a number, the partition you want to set Active)

fdisk -e /dev/rdisk0

flag x

That will not work with extended partitions, though.

ok i got off that error too.. but now it just gives me a blank cursor during boot.. what to do now ?

[hecker]

What exactly did you do when you say you "got off that error"?

You have to let us in what you do so we can understand how to help you, bro.

 

I can assume that your MBR got screwed. You said you re-installed OSX on that partition again. Did you run fdisk again to see what it shows in the list?

I would also point out that maybe the best solution would be to install a good bootmanager like Acronis so you don't have to configure stuff through the terminal.

i googled for the "MBR error 3 " and downloaded a boot cd from some where and got past that error. now i m trying with Acronis OS selector.. hope this works..
