Multi - Boot recomendation

[roche]

Hello,

I am going to install in my machine Windows + Several Distributions (Sarge + Ubuntu)


I want to hear some advices about the partitions that I need. My Hard Disk space is 60 Gb

I am thinking use for windows 10 Gb, For Debian 20 G distribuited in 3 partitions for (/,/home,/usr), Ubuntu 3 partitions (/,/home,/usr)

Somewhere I read that is good to have a partition for /boot in order to allocate all the kernels, files and others stuff for all the distributions ? Is that Correct?

It saw like I can share /home among the Linux Distributions but I am not very sure.


Per every system Do I need to have Primary Partitions or they can be located in extenderd partitions?

I dont want to rewrite one distribution or mess up the the boot files,

Can someone give an advice with these?


I going to use Grub.



Thanks
