currently have lion , windows 7 (through bootcamp) installed on late 2011 mbp. created 8gb linux swap partition off of osx partition , no longer boot windows. fixed deleting newly created partition resetting partition active using fdisk.
make sure don't mess again, how go triple booting adding linux without formatting of current partitions. searching around, people said should create partitions through windows side , install linux normally. work if create 2 partitions off of windows? 1 swap , 1 normal?
as has done lot, in 1 serious rabbit hole of pain. mess again. need learn mbr , gpt, , how apple hardware boots in efi mode , csm-bios mode. you're better off csm-bios booting linux, windows. or you're asking more pain dealing drivers when booted via efi. in case, vbios corruption on 2008 , 2011 mbps when efi booting linux, i've resigned using csm-bios booting.
other complicating factor of boot loaders. csm-bios booting depends on loading code in first 440 bytes of mbr , chain loading rest of boot loader. windows has own boot loader. linux has own boot loader. don't co-exist, although grub boot loader chain load rest of windows boot loaders.
basically, you're asking question how drive oxen san francisco. there lot of ways this. there isn't 1 correct way it. there lots of wrong ways it.
i've found gdisk invaluable in editing gpts. , create hybrid mbrs. triple boot, have use more partitions there available in mbr, can have four. one, first one, must 0xee entry, leaving three.
strategy partition such mac os first, linux second, , windows last. if gpt like
1. efi system
2. mac hd
3. recovery hd [lion only]
4. bios boot [used grub2 on gpt disks]
5. linux /boot
6. linux lvm
7. windows
use gdisk add 7th gpt partition 2nd mbr slot. let add gpt partitions 1 through 6 mbr first entry type 0xee "protective".
1. 0xee protective
2. hfps/ntfs "windows"
, mark boot flag (active flag) on mbr partition 2.
every gpt partition entry mbr tool, including windows, should never touch, stuff protective mbr partition. expose windows partition in mbr. windows installer not touch sectors reserved in mbr entry 0xee, 2nd entry sectors windows.
