Darwin Dual Boot Died

[Windtosh]

Posted this originally in Tiger area, but are running Leopard here (2nd partition) with Vista 32 on the primary partition. Not sure how to attempt to repair, if it is repairable, but the partition in the working Vista startup partition sees the OSX partion as Fat16???.

 

I realize this relates to an earlier post (we are in Leopard) , but in searching, it applies to our dilemma. We have a Wind with Vista 32 over the shipping XP and a fully functional OSX build on dual boot. We lost the Darwin unexplicably , but the install is still there and didn't want to wipe the disk and do a fresh install.

 

In Disk Utility using the OSX install disk doing verify and repair, it returns:

____________________________________________________________

 

Verify and Repair Volume "disk0s2'

 

** /dev/disk0s2 Invalid BS_jmpBootblock :fa31c0

 

ERROR: File System verify or repair failed.

____________________________________________________________

 

We tried the following previously posted procedure by Xedek, but am unclear how it applies to Vista on the 1st partition and OSX on the 2nd partition as far as labels and flags go. We have tried different combos without success. Using FDisk variations and changing flags didn't work either.

 

Please help.

 

Thanks

 

Following is someones' post I tried, but to no avail.

QUOTE(Xedek @ Aug 4 2007, 06:07 PM) just wanted to share how i got rid of my hfs+ problem...i tried everything in every fourm i came across. i was getting the permission denied when ever i tried to use the fdisk command in terminal, so i tried the sudo command and that got rid of the hfs problem but then it wouldnt boot at all....

 

to solve this, this is what i did

 

1. put the installation disk in the drive

 

2. when the darwin bootloader screen pops up press f8 and then type -s and enter to enter single user mode

 

3. single user mode is like booting from a windows floppy boot disk...you get just a command prompt

 

4 set the active partition and save the mbr

a. fdisk -e /dev/rdisk0 (the drive location that OSX was installed on 0 based)

b. flag 2 (the partition number OSX is on 1 based)

c. update

d. write

e. quit

f. reboot

 

5. take out your osx disk, you should now be able to boot into mac no problem.

 

 

EDIT::: if you dont plan to use vista stop reading here...you should now be working with OSX and if you have it installed xp as well

 

6. after i did this windows vista would refuse to boot for me so i had to fix the vista install, but vista wont see the install unless you make it the active partition, so reboot back to the OSX disk and go into single user mode again then type the following

a. fdisk -e /dev/rdisk0

b. flag 3 (in my case vista was on the 3rd partition this may be different for you)

c. quit

d. reboot

 

7. take out your osx disk and let windows vista try to start

 

8. vista should now give you an error while trying to boot along the lines of winload.exe is corrupted this is good

 

9. throw in your vista install disk and reboot

 

10. go through the first menu where you select your language and such and click repair on the bottom of the screen

 

11. vista should find the error and repair its self

 

12. now reboot and all your problems should be gone...i chose to use darwin as my boot loader so i used a partition manager to change mac back to active and make vista in active

 

hope this helps those of you still having problems

 

 

:::EDIT::: listed out my steps to get it working in stead of saying follow fdisk commands ________________________________________________________________________________
