Hello,

I'm installed Windows on a MacBook and additionally rEFIt in order to manage three partitions:

1) Mac OS
2) Data partition
3) Windows (NTFS)

Everything worked fine. At the end I wanted to change the Data partition from Mac OS Extended file system to NTFS (in Mac OS, not from Windows). Now I can't boot Windows anymore.

This is the report from rEFIt's partition inspector:
Code:
*** Report for internal hard disk ***

Current GPT partition table:
# Start LBA End LBA Type
1 40 409639 EFI System (FAT)
2 409640 63051575 Mac OS X HFS+
3 63313720 201474087 Basic Data
4 201736232 234441607 Basic Data

Current MBR partition table:
# A Start LBA End LBA Type
1 1 409639 ee EFI Protective
2 409640 63051575 af Mac OS X HFS+
3 * 63313720 201474087 07 NTFS/HPFS
4 201736232 234441607 07 NTFS/HPFS

MBR contents:
Boot Code: Unknown, but bootable

Partition at LBA 40:
Boot Code: None (Non-system disk message)
File System: FAT32
Listed in GPT as partition 1, type EFI System (FAT)

Partition at LBA 409640:
Boot Code: None
File System: HFS Extended (HFS+)
Listed in GPT as partition 2, type Mac OS X HFS+
Listed in MBR as partition 2, type af Mac OS X HFS+

Partition at LBA 63313720:
Boot Code: Windows NTLDR
File System: NTFS
Listed in GPT as partition 3, type Basic Data
Listed in MBR as partition 3, type 07 NTFS/HPFS, active

Partition at LBA 201736232:
Boot Code: Windows NTLDR
File System: NTFS
Listed in GPT as partition 4, type Basic Data
Listed in MBR as partition 4, type 07 NTFS/HPFS


Does anybody know what I have to change and how I can do that so that I can boot Windows again?

Thanks!

From your description, it looks like your data partition is the active one in your MBR. Is that right? Wouldn't you want it to be the (last) OS partition?

Plus what Granny said, what did you use to convert the data partition to NTFS under OS X? NTFS-3G? Paragon? ...

Yes, I changed the file system of the data partition from Mac OS to NTFS, using Paragon (in Mac OS).

How can I set that the data partition is not an active partition anymore? I just want Mac OS and Windows to select from the rEFIt menu at startup.

As far as I understood, the order of the partitions has to be MacOS - data - Windows in order to handle three partitions on a MacBook using rEFIt.

Is there no possibility to make the change just with rEFIt?

Thanks!

I don't know, as I don't use it myself.

I know it provides tools to view the partition tables and sync the gpt and mbr ones, but know nothing beyond that.
