hey im really new to ubuntu but over the past few weeks I have brought some old machines back from the dead by running ubuntu rather than windows and im loving it, even convinced my dad to get rid of winidows 10. So I decided to dual boot my main pc running windows 7 and focal fossa yesterday. left all the partitioning up to ubuntu installer and im already out of space, it gave me 9gb. now im having difficulty booting ubuntu and getting loads of warnings about low disk space.
been in to windows disk manager and unallocated some space, made a bootable gparted usb which i cant get to run keep getting a message saying no bootable partition in table, then remembered i have a bootable usb that i installed ubuntu with(literally hours earlier).
so im on my live usb in gparted, and i cant resize the ubuntu partition, made a bit more unalocated space in gparted but still cant make my ubuntu partition any bigger.
what am i doing wrong? would i be better just reinstalling ubuntu (im 6 hours in and 5 of them have been spent trying to resize a partition)
