I want to dual boot Windows and Ubuntu from my computer, which has only Ubuntu installed. I have done dual booting before but in that case, Windows was installed first. Here are my Ubuntu partitions:
And I want to free up some 60GB space for my Windows. How do I do that?
It is inadvisable to modify mounted partitions.
Thus, You should boot from a LiveCD or USB.
First make a back up of your data in case of problems.
Use gparted to shrink your home partition.
Then create a partition for the windows install.
Boot the windows installer. and install it to the partition.
Note: windows will write a bootloader to EFI/boot/bootx64.efi. If you use device boot, Grub will need to be put back in.
