add tinyvista without affecting my triple boot syste,

i currently have 7 partitions on 160gb using grub boot loader

20gb xp
15gb osx

extended partition
4gb extenmded partition for knoppix
4gb exnteded partition for open suse v11
1gb linux swap

rest data partition

i want to put rons tinyvista rev02 on to it . i beleive it is just a 699mb ghost image. that will expand to 2.5gb ? so i intend to make a new 5gb partition and resize the data partition .

1 how can put it on without it affecting the mbr ?
- will i loose my grub boot lader , hence making all my paritions lost when vista wipes my boot loader
2 how much hdd space do i have to give it , will 5gb be enough as i will only be using to test vista as i have not used it before . xp will be my main OS for work

 

does leapord have to be in a primary partition or it can be extended logical partition?

as i can onlyy make 4 partitions max but i have done this to my 160gb hdd

primary , ntfs , 20gb , xp - instaled
primary , hsf+ , 10gb, osx - installed

logical partition
logial drive, ext3, 4gb, knoppix - not yet
logial drive, ext3, 4gb, open suse - installed
logial drive, swap, 1gb, linx swap - created

unallocated black space 1gb - i cannot make use of this
primary , ntfs, 100gb , data/document partition


- so i have to make another for tinyvista , i am thinking to put either before or after osx partitin and move all partitions down or make xp in primary partition and then put all other partitions in to logical partision and a data primary partition ??

- so will osx install ok in a logical parition ?

my current partitions and how i want it to

see here please

 

OSX WILL not boot from logical partition so i am thinking of this partition config =
