Hi Thanks for this video. Very good explaination, just 1 query that in 4:00 min of video you mentioned that MBR can support 14 partitions i am not clear with this portion. Because i know and further you also mentioned in video that MBR support 4 partitions. Please help i am confused in this portion.
MBR supports three types of partition: primary, extended, and logical on a single disk. We can use only primary and logical partitions for data storage. We cannot use the extended partition for data storage. It stores logical partitions. Technically, MBR supports only four primary partitions numbered from 1 to 4. If we need more partitions, we need to convert the last primary partition into the extended partition. Inside the extended partition, we can create up to 11 logical partitions. Thus, we can create a maximum of 14 usable partitions (3 primary and 11 logical) on a single disk. The numbering for the logical partitions starts at 5.
Yes, that is why the concept of primary and logical partitions was used to create more partitions. This concept allows you to convert the last primary partition into logical partitions. Logical partitions reside inside a physical partition. Only the operating system sees logical partitions. BIOS only considers the physical partitions.
Thanks for sharing! Very useful refresher!
Glad it was helpful!
excellent！
Welcome
Such a knowledgeable video ,thaks a lot
My pleasure

Thanks but one thing, BIOS supports maximum 4 primary partition not 14.

Can’t you use LVM with GPT? I think I saw some TH-camr do that
You can use LVM with GPT. LVM is a partition type while GPT is how the hard disk stores partition information.
Imagine creating a separate partition for every different type of file on your system
Ya, you can do it. But you should create partitions based on your requirement rather than one for each type.
