Disk partitioning in Ubuntu 20.04 LTS

bd flag
  1. What is the sequence that happens with Ubuntu during startup? E.g. is it /root first, then /boot, then swap, then /temp and finally /home? I'm asking because I want to do the partition sequence as per the OS does it while we press power button.

  2. If C: is the primary partition in Windows, then other drives are so simple as in we can tag movies drive, song drive and so on to keep our mp4 and other files. In the same way, is /home equal to movies drive/song drive whatsoever, etc.?

  3. I have 500 GB of a SATA hard disk, and I'm OK to go with Ubuntu 20.04 LTS desktop version. In that case, what would be my / partition? What would be my /boot partition? And last, what would by my /home partition? And can I have more than one /home partitions?

Welcome to AskUbuntu. You may be over-analysing your situation. Having read through your three questions a couple of times, I do not see any reason why you want to have such nuanced control over the position of the partitions on the hard disk. There is no need for partitions for temporary space nor swap. Additional media disks — if you're storing movies and audio files off the main hard drive — can be given dedicated directories if needs be. TLDR; the default installation will give you the partitions you need in the order that makes the most sense.

Thank you so much "Matigo" for you help , which i really appreciate , but then again just one more thing as in question to add-on..."as i want to know , if in future i want to install heavy application's , as at that time the space allocation as in 15-20 etc. would not be engouh".. hope you've got what i mean?

I don't get what you mean. Do you plan on installing Ubuntu alongside Windows and, as you need more space, steal from Windows and give to Ubuntu on an ad hoc basis? If so, you will not like the amount of work involved in both OSes. Partitions can certainly be modified, but this is not for the faint of heart ... or those without *really good* backup mechanisms in place

If you have UEFI hardware which systems since 2012 are, you need an ESP. If dual booting with Windows the Windows ESP will be shared. You do not need /boot and swap partition is now optional. Default is a 2GB swap file, but some still like swap partition of 4GB. If UEFI be sure to boot installer in UEFI boot mode and have drive as gpt partitioned. http://askubuntu.com/questions/743095/how-to-prepare-a-disk-on-an-efi-based-pc-for-ubuntu

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
