Reinstalling Vista from recovery drive?

Hi guys, I did post this problem a few days ago in the hardware section when I thought it might have been a HD issue but now its a software one.

Acer Aspire 6930G with Vista home

My laptop froze up a few time's then wouldn't let me boot at all give me:-

For Atheros AR8121/AR8113/AR8114 PCIE Ethernet Controller v1.0.0.12(2008/07/26)

check cable connection!
PXE-M0F: Exiting Intel PXE ROM.

And sometimes "operating system not found" come's up under it.

I know now it didn't see an OS and was trying to boot fom a network.

ALT F11 to start eRecovery and my recovery disks dont work. I've got nothing on the laptop I need to keep as I backed it up using a caddy on to my desktop.

So can someone please tell me how I can reinstal Vista from the recovery drive or even make a copy of Vista from the recovery drive using my desktop.
I've used windows comander and can see the recovery partition is on the X:.

 

Re-seated the ram and its sorted!!!
