@stephane Thanks. Checked all BIOS options. There is no mention of AHCI. The installer also does not talk about AHCI. Is there a setting I have to do manually?
Well, you can try manually partitioning the disk [a /boot/efi partition with boot flag, a / partition with root flag, and swap and others if needed] to see if that works …
AFAIK the installer will create the partitions, but not the partition table.
You should have a partitioning tool such as gparted bundled in the liveUSB for preparing the drive.
Looks like some kind of bug in the new iso. I also tried to reinstall Manjaro to a SSD using the 21.2.4 KDE full and minimal iso. It gave the same error as @deshmukh though I had previously reinstalled Manjaro on that device 3-4 times, successfully.
Maybe @Manjaro-Team should take a look.
After a few trials and initially formatting the disk to ext4 and then launching calamares, somehow it worked…
