Would this partitioning scheme work for penta-boot system?

Question

I'd like to have many operating systems on one HD in my laptop. Booting from USB is not an option; I have to boot from the HD.

Is the following partition scheme sensible?

What should I do for swap partitions?

4 primary partitions containing

• Recovery stuff
• Windows 7
• Linux (eg Fedora)
• EXTENDED partition containing
  • logical drive with Linux (eg Sabyon)
  • logical drive with Linux (eg Mageia)
  • logical drive with /home

This would all be on one hard drive. I understand that there's a 2 TiB limit; the drive is 500 GB so that's okay. I understand that I'd need a boot loader to boot the OSs in the extended partition's logical drives. I plan to use maybe GAG or Smart Boot Manager. (I know software suggestions are strongly discouraged, but I'd welcome suggestions for FOSS boot loaders in the comments)

EDIT: This question is about the particular situation of wanting to have more that 4 bootable OSs on one drive. The user can only have 4 primary partitions with a bootable OS in each. What does a user do if more partitions are needed? Can an OS be booted from a logical drive in an extended partition?

Answer 1

Skip trying to mess around with logcal drives in your MBR partition, and use LVM for all of your linux filesystems.

• Recovery stuff
• Windows 7
• shared /boot
• LVM - Volume group - create the group, and create small LVs, add space to LVs when required.
  • shared /home so you have access to your data everywhere.
  • logical volume {1..n} the root fs for as many linux distros as you want.
