Please look at the following screenshots.
Is /dev/sda1 useful at all (Windows says it is a Recovery Partition)? Can I remove it? It is only 1000MB and removing it seems no use, so the best I can do is just leave it?
/dev/sda5 and /dev/sda6 are Recovery partition and OEM partition, and they occupy 14.4GB + 7GB in total, can I delete them? How shall I modify the boot so that deleting them won't mess up the boot (in /dev/sda2)?
Is it possible to move linux backward (to the current /dev/sda5 and /dev/sda6) without affecting Linux data (and may be a little larger than current space)? What I wanted to do is to increase Windows 10 partition a bit by moving Linux backward.
The pictures are attached below.
Thanks.
