Managing Dual Linux OS and Partitions on PC

Click For Summary
SUMMARY

The discussion centers around managing dual Linux operating systems on a PC, specifically ArchLinux and Ubuntu, along with their respective partitions. The user seeks to uninstall ArchLinux by formatting its partition (/dev/sda2) and potentially deleting the boot partition (/dev/sda1). It is confirmed that Ubuntu can boot using the EFI system partition (/dev/sdb2), suggesting that /dev/sda1 is not necessary for Ubuntu's operation. Users are advised to check BIOS boot sequences before making any changes to partitions.

PREREQUISITES
  • Understanding of Linux partitioning and file systems
  • Familiarity with UEFI boot processes
  • Basic knowledge of partition management commands in Linux
  • Experience with dual-boot configurations
NEXT STEPS
  • Research how to safely format partitions using tools like GParted
  • Learn about UEFI boot management and configuration
  • Explore commands for managing partitions in Linux, such as `fdisk` and `parted`
  • Investigate the implications of removing boot partitions in dual-boot setups
USEFUL FOR

Linux enthusiasts, system administrators, and users managing dual-boot configurations who need guidance on partition management and UEFI boot processes.

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 ?
