yes, @Pilot6 . The reason is irrelevant, but "My old 18.04 partition is going to fail soon due to bad block and Im moving to another one. As HP limits the number of partitions I can have, I care about creating new partitions".

HP doesn't limit the number of partitions. MBR maybe does.

No, you only need one EFI partition. My dual-boot system shares the one partition between Windows and Ubuntu.
You can see it here with all the goofy Windows partitions. (My / partition is on a different physical drive)

You may need multiple EFI partitions only in some special cases when you swap disks, change boot device in UEFI, etc.
