Q: Issues with hybrid mbr and bootcamp partition
HI, i'm trying to install windows 7 via bootcamp on Mac Os x and created 2 additional partitions.
created the bootcamp partition with bootcamp assistant.
Then while bootcamp was partitioning hit the eject key and to eject the windows installation DVD and quit installation
Went to Disk Utility and created 2 more partitions LINUX SWAP and Ubuntu.
so i understand that the gpt side was created but not the mbr
this is the output of sudo gpt -vv -r show /dev/disk0 :
gpt show: disk0: mediasize=320072933376; sectorsize=512; blocks=625142448
gpt show: disk0: PMBR at sector 0
gpt show: disk0: Pri GPT at sector 1
gpt show: disk0: Sec GPT at sector 625142447

So my question is can i go ahead and install first linux then windows (which is already formatted as MS DOS (FAT 32) provided that i have already created the hybrid MBR as you can see above.
1. I would change the type code for partition 4 to 8200, and partition 5 to 0700 before installing Linux. Use 0700 because due to poor planning, the parted developers borrowed the Microsoft basic data partition type GUID for Linux partitions on GPT disks. Only very recent installers understand type code 8300.
2. Install Linux, this will remove the hybrid MBR you've already created.
3. In gdisk recreate the hybrid MBR.
4. Install Windows.
need it is crucial that i do not use bootcamp to create a bootcamp partition but gdisk instead to create every partitions,
Assuming you already have Windows install media prepared and it boots the Windows installer, you don't need Boot Camp Assistant for anything.
LONER T, is there a way to convert it beforehand to NTFS?
No, just reformat it NTFS in the Windows installer.
