I fell in love with linux again.

My root partition was full and for past few days I have been deleting/moving stuff to get my work done.

And since, it was MBR I thought I had no option except for reinstall arch and setup everything again.

Just converted MBR partition to GPT and also setup UEFI boot instead of legacy without formatting anything.

Then extended the root partition and now I can create unlimited primary partitions.

PS: It was work laptop and I didn't take any backup.
