Can I delete the Arch Linux partition and boot partition if Ubuntu has its own EFI?

[dRic2]

Hi,

I am running on pc with 2 different Linux OS and the following partitions

/dev/sda1 (Boot)
/dev/sda2 (ArchLinux)
/dev/sda3 (something empty)

/dev/sdb1 (Ubuntu)
/dev/sdb2 (EFI System partition)
/dev/sdb3 (no name)

Since I basically don't use ArchLinux, I wanted to uninstall it. I though of formatting the /dev/sda2/ partition with together with the /dev/sda3/ and make a new empty partition for data. I was wondering if I can delete the /dev/sda1 as well, since to boot ubuntu I should just need the /dev/sdb2, right?

Thanks
Ric

First seriously consider checking how your BIOS boot sequence(s) are set before you do anything at all.

Hi, sorry for the late reply. So my boot options are the following:

UEFI BOOT:
Ubuntu
UEFI: Crucial_CT(...lot of numbers)
Linux Boot Manager

I am not an expert, but I would guess that the /dev/sda1 in Post #1 is not used to boot ubuntu. Right ?
