Open windows and shrink your boot partition by whatever you want Linux to take. Leave the space unallocated and delete any secondary partitions you may have already created in the first failed installation.
Then, start the Linux installation again and see if that works.
If you have a second drive that’s a much better choice because windows will regularly fuck up the Linux part of the bootloader and good luck fixing it.
Go log into windows, backup the second drive files somewhere else and format it, then install Linux there.
I just hop into my uefi menu on boot and select the windows disk to load whenever required instead of a dual boot bootloader because I know windows will not damage it
Still waiting to see the inevitable hack of a communications constellation (starlink and the likes) resulting in worldwide outages and / or a worldwide firework show.
