I’m currently using Ubuntu 24.04 on Acer Aspire Lite AL15G 52 and trying to downgrade to Ubuntu 22.04 by booting from a USB drive. However, the system freezes during the boot process from the USB. Below is a picture of error am encountering
I created the iso image using "dd" with command: sudo dd if=ubuntu.iso of=/dev/sda status=progress bs=10M && sync but i don't think that's the issue here cause i installed Ubuntu 24.04 in the exact same way and boot settings and chose the option to erase disk (uninstall windows 11) and it worked.
Edit 1: I am trying to install ubuntu-22.04.4-desktop-amd64.iso and previously i installed ubuntu-24.04-desktop-amd64.iso without any issues with same boot settings.
Edit 2: Based on @oldfred's comment, here's the output of "gdisk" command:
$ sudo gdisk -l /dev/sdaGPT fdisk (gdisk) version 1.0.10Partition table scan: MBR: protective BSD: not present APM: not present GPT: presentFound valid GPT with protective MBR; using GPT.Disk /dev/sda: 244457472 sectors, 116.6 GiBModel: SanDisk 3.2 Gen1Sector size (logical/physical): 512/512 bytesDisk identifier (GUID): ABBD44C4-640C-4CEA-ACCB-CA38273F602EPartition table holds up to 248 entriesMain partition table begins at sector 2 and ends at sector 63First usable sector is 64, last usable sector is 9799460Partitions will be aligned on 4-sector boundariesTotal free space is 1 sectors (512 bytes)Number Start (sector) End (sector) Size Code Name 1 64 9788791 4.7 GiB 0700 ISO9660 2 9788792 9798859 4.9 MiB EF00 Appended2 3 9798860 9799459 300.0 KiB 0700 Gap1Apart from "dd", i also used "etcher" to flash the ISO again and even reflashed the ISO with "dd" again but cleared the partition table with: sudo wipefs --all /dev/sda this time to see if it works & encountered the same error in both cases. I even changed my USB to another one but that also resulted in same error so i assume it has nothing to do with the USB am using.
