Re: Always has no options when picking partitions(?) when installing
That looks pretty standard for a Dell computer with Windows 7. The question is, what does gparted say when you hover or click on the OS partition?
For Vista or Win7 it is best to resize a Windows partition from within Windows, but I rarely boot Windows, so I think it is in Administration Tools, Disk Management. Then reboot so Windows can check the partition and make sure it is okay.
My guess is that either install shrunk the "OS" partition or you did, which marks it as dirty so Windows will check it next boot. But if you have not booted into Windows since then, the (!) is probably because the "OS" partition is still marked as dirty and gparted will likely suggest checking it with chkdsk /f from Windows (which it should do automatically if you boot into Windows).
This is an example of Dell computer with 64-bit Win7, 64-bit Ubuntu 12.04 on sda4 and 64-bit 11.10 on sdb (SSD). I have 8 GB RAM and do not hibernate, so no swap needed:
