I have Lion 10.7 and Windows 7 64 bit (Boot Camp) installed on my Mac Mini.
They both boot fine. But when I tried to run Windows 7 from Parallel using existing Boot Camp, I encountered problem stating
After some googling, I found it is caused by
MBR misaligned and can be corrected by using
gptsync tool of rEFIt.
I installed rEFIt in my Lion partition and Partition Inspector shows a report with
Current GPT partition table: # Start LBA End LBA Type 1 40 409639 EFI System (FAT) 2 409640 740644007 Mac OS X HFS+ 3 740644008 741913543 Mac OS X Boot 4 741914624 976773119 Basic Data Current MBR partition table: # A Start LBA End LBA Type 1 1 409639 ee EFI Protective 2 409640 740644007 af Mac OS X HFS+ 3 740644008 741913543 ab Mac OS X Boot 4 * 741914624 976771071 07 NTFS/HPFS
The problem is when I boot Mac mini in rEFIt and run
gptsync in shell it only shows
Shell> gptsync Error: Not Found returned from gptsync.efi Current GPT partition table: Current GPT partition table:
What was I doing wrong? And how could I sync GPT and MBR table with or without gptsync.Update
I manage to run gptsync on Mac using enhanced gptsync from here. Now the problem changed to
Writing new MBR... gptsync: Data write failed at position 0: Bad file descriptor
