I have both windows and ubuntu installed in my computer, and I wants to extend my ubuntu root space, but I have some complicated problems, here is the image:
as you can see, my boot is installed with my windows boot. On the other hand, my ubuntu is installed in another disk, and is shown here:
I'm a new to linux, Since it is not LVM, I think I should resize my root by Gparted liveCD, deleting dev/sdb3 and resize root to include unallocated space, but:
1) I don't know whether deleting /dev/sdb3/ with label "boot, esp" will cause any problem?
2) Since bootloader is in other disk, will I lose bootloader?
3) I have checked the existing post in askubuntu, and in here
it said that resizing disk space in gparted is enough and just reboot, but in some other post, e.g 
, it is required to rebuild bootloader by myself, which one is correct??
