has alluded, the answer is eminently
On MBR-based computers, you can have a "minimum maximum" of 15 -16 partitions as Logical, with only 3 of them being Primary.
By "minimum maximum" I mean that that is at the least - in some cases you can have more, but I have not explored how many, myself.
I have had 7 Linux installed in Logical partitions, but not for a few years now, as I predominantly am UEFI-GPT based.
Best practice is to have Partitions 1, 2, and 3 as Primary, and make Partition 4 an Extended Partition, under which the Logical Partitions can be created. 11 - 12 of them, space permitting.
Duc Anh's basic specs are found at his other Thread, here
and I believe he may have a 500 GB HDD. Is that so, Duc Anh?
There need be no separate Boot partition created, he can simply have the Installer load the bootloader to /dev/sda (no number).
I have to go for my evening in Australia shortly, but I can be back with more tomorrow.
