tri boot osx86 install - partition lost

[evilmatrixhacker]

Hi folks,

I just did a tri-boot on my pc. the trick of creating the type af partition worked well, but

1.) the osx boot sector wasn't on my sata drive

2.) my third HD (a 160 GB drive) lost the partition information

 

I used the disk utility, formated the third partition of my sata drive and installation went well.

But: after the first bootup I got a message "drive format is not recognised. format, ignore, eject?"

I have chosen the ignore option twice. When I booted my windows 2000 my 160 gb drive appeared as raw and dynamic disc.

 

does the disk utility of the MacOS have a bug that corrupts partition tables?

 

I assume that the writing of the mbr did some bad things to my disk. The other NTFS drives could be seen in Macos so I assume that the error encountered while formatting the partition on the SATA drive or writing the boot manager of the OSX, that is NOT on my SATA drive.

 

my config:

Asus P4C800 deluxe, P4 SSE2, 2 GB Ram

in Bios:

primary master is a 80 GB IDE with one NTFS partition

primary slave is a 160 GB IDe with one NTFS partition (now lost)

secondary master is a DVD writer

secondary slave is a DVD drive

Third master is my SATA drive (36 GB), this is set to be my boot drive, with three partiions - Windows, Linux, Macos

Your data are really lost?

Do you tried a Linux Live-CD if you can mount something or see your partition with cfdisk?

Thanks for your remark!

 

 

I took the Suse boot-CD and discovered that the partition type was set to 42 - Type SAS but the partition size was correct. I did set it back to 07 (NTFS) , and thats it.

 

Maybe it's a good idea to disconnect all unnessesary drives because the OSX installer doesn't remember from which DVD it was booted and mounts always the first DVDrom found even if it had booted from the second, and possibly gets confused if there are more than one harddisk attached.

 

Remark: 42 is a magic number for developers... also in Windows NT it appears: the accounts expire after 42 days, and there are some more appearance of this number that's originating from the Hitchhikers Guide. You may think by yourself what this means, but it's surely not a feature because also MacOSX doesn't know how to handle this filesystem type, but maybe a hint
