Remove Old Windows Installs

Ask the Doctor LogoI just bought and installed Windows 7 Pro. Previously, I was dual-booting Windows 7 RC and Windows XP on a 500GB split-partitioned drive. Windows 7 Pro is on a new 320GB HDD.

How do I remove Windows XP and 7 RC from the boot selection screen and just have the computer boot straight into Win7 Pro with no selection screen?

Once I take care of that, I want to remove the partition and use the 500GB HD as data backup. All my data stored on the partitioned drive has been moved over to either the C: drive (7 Pro) or another 320GB HD installed or an external HD.

Videocard Overkill

Ask the Doctor LogoI have two older systems: an Asus A8V-VM board with an Athlon X2 4800+ at 2.5GHz, 4GB of OCZ Platinum DDR/400 RAM, and a GeForce 6200 in a PCI-E x16 slot; and an old OEM eMachines board with an Athlon X2 6000+ at 3.0GHz, 4GB of OCZ Platinum DDR2/800, and onboard GeForce 6100 graphics, with an empty PCI-E x8 slot.

I want to upgrade one of them with a Radeon 5000 series to hold me over until I can put together a Lynnfield system. My concern is that both of these boards only have a PCI-E 1.0a slot. Would I notice any real performance difference between the Radeon HD 5750 vs. the 5970? Or would I just be wasting my money on the higher-end card?

Stuck in the 4GB Morass

Ask the Doctor LogoI want to know if 32-bit Windows 7 will limit how much system memory I can install. I know that 4GB is the maximum that 32-bit Windows XP will recognize. Is this the same for Windows 7? Do I need to buy 64-bit if I want to install more than 4GB memory?
