Partitioning progarm that allows resizing existing partitioins w/ a UEFI BIOS

[videobruce]

Existing HDD with three partitions (one active) from a conventional BIOS to a UEFI based BIOS
The 1st partition is only 10GB. I want to double it for Win7 (no games, non O/S files are stored outside the active partition. I don't need any more room). The 2nd & 3rd are storage that I want to keep. The extra 10GB would come from the 2nd partition.

Switching from a conventional BIOS to UHCI, is that any problem for non active partitions as far as loosing data and having accessibility?

I have been using EaseUS & Partition Manager, but neither will allow me to resize an existing HDD's partition without wiping the entire drive. I haven't tried GParted yet.

I'm looking for a program that I can boot from. Input?

(I hope that made sense, ask if it didn't)

Gparted should work on GUID partitions

You could also run a Linux live distribution and use gdisk (the GPT version of fdisk.

http://sourceforge.net/projects/gptfdisk/ It is a command line tool, but is more versatile than gparted. There is a tutorial here: http://www.rodsbooks.com/gdisk/

Of course, having resized/moved/created the partitions, you will also need to resize the filesystems to fit.

I'm sure you are aware that editing partition tables is a potentially risky business, so make sure you have backed up all your data first. A safer but more long winded method might be to back-up your data, wipe the disk and start again.

That is above my pay grade, but GParted I would like to try.

Understood. I have backed up my data, but I wanted to avoid doing this and would also like the experience going my planed route.
