Hi, all. Basically, I've been using Ubuntu exclusively for around 2 years now, but I want to regain most of my hard drive space after realizing Windows Vista took up so much. I'm a fairly novice user, so I still get a bit nervous using the terminal and stuff.
I have an old HP Pavilion DV7 laptop (technically it's a desktop now) which I installed Ubuntu on via a LiveCD, and upon booting it shows the HP boot options, with the option to change BIOS settings, etc, then it shows the regular GRUB menu.
Here is the output of sudo fdisk -l:
From what I can figure, sda1 is Vista and sda2 is the Windows recovery partition.

/dev/sda6 593827840 598075391 2123776 82 Linux swap / Solaris
My main question is, seeing as how /dev/sda1 is set with the boot flag, is it still safe to just use a LiveCD version of gparted and delete it, or would that screw up my whole boot process? The fact that the HP menu shows up first before GRUB, and that little asterisk under sda1 are the only things leaving me extremely nervous about just deleting it outright.
