actionparsnip:  in the allocation menu the installer has 435 GB of the 750, selected,
when running windows that drive is only 405 GB,    the allocator leaves 405 GB and 29G left over
and in the advanced partition editor is DOES show each /dev/sda   1 - 2 - 3 -4 -5
I just wanted to say that,   it's not my computer and I just want to be really sure thats all.

so your saying that if I delete the /dev/sda5  which is empty...nothing on it,  but ntfs,  435gb,
I will be able to use that partition, and not effect the rest of anything ?

even though in the allocator its 405GB with some mystery 29GB left over, and
in advanced editor its 435GB ?

sorry man, I trust your advice just wanted to clear those up
so yea still same answer?  delete the partition which I want to install
/devsda5 "which is empty"   not containing windows.  ?
