I have a big deal here. I have a MacBook with three partitions:
- HFS partition for Mac OS X 10.6
- NTFS partition for Windows 7 64-Bit
- NTFS partition for my documents
It thus works with both GPT and MBR. I use rEFIt to switch the system at boot.
Having had troubles with my Windows roaming increasing dramatically (what a pain), I had to increase the size of my second partition after reducing my third partition...
My problem is that my partitioning tool did a mess with the GPT and the MBR (I am a beginner to these systems and I used EaseUS's tool to work on the partitions. It was a big mistake.)
Now I have the following.
In the GPT
Partition Start LBA End LBA Type 1 40 409639 EFI System (FAT) ⇐ The boot sector, I guess ⇐ I miss my Mac OS partition (the entry was suppressed by Easeus) 2 126240768 252067839 Basic Data ⇐ My Windows partition 3 278693928 976773165 Basic Data ⇐ My Documents partition at the right place
In the MBR
Partition Start LBA End LBA Type 1 1 409639 EE ⇐ The boot sector I guess 2 409640 125976615 AF Mac OS X HFS+ ⇐ My Mac OS partition at the right place etc 2 126240768 252067839 07 NTFS/HPFS ⇐ my Windows partition 3 252069888 976773165 07 NTFS/HPFS ⇐ my Documents partition at the WRONG old place
rEFIt offers me to automatically copy the content of my GPT to my MBR: It would give me back access to my "documents" partition, but I would lose my OS X partition.
How do I manually write in those GPT and MBR to setup both sides? I heard it would be possible with UBCD …
