Problem installing Windows 7!!!

If anyone has had this problem and/or knows a solution it would be greatly appreciated! I'm losing my mind trying to figure it out!

I have an old Dell Dimension 3000 with Windowns XP and I'm trying to upgrade to Windows 7. I've tried to install it with a bootable DVD but XP just starts up as usual, I've also tried 2 different bootable flash drives, on start up, I hit F12 and change boot sequence to USB Flash Drive, that seems to do something as a loading files screen appears but once loading completes, XP just starts up again as normal and no Windows 7 installation screen appear!

Anything obvious I'm doing wrong here? As I'm quite a novice at this sort of thing!

Clarification Request
Enter the BIOS

Set it to boot first to the DVD and then to the HDD as second device. Also make sure you actually have a DVD drive on that computer, since if it's a CD, it will not run the DVD and will default to the HDD. I suspect that is your problem.

What size is this hard drive? 40 GB? If so, you couldn't run W7 very long on that anyway.

Give Lubuntu a try. It can boot from CD, is currently supported, and a 40 GB HDD isn't too small for it, if you choose to install. You can try it out fully before install, but can't save anything from CD since that's "read only", but otherwise will run entirely from CD.
Give this a try. Download this ISO file and "burn image" to a CD writeable disc. Boot to it.

Re: problem installing Windows 7

First of all, are you sure that your PC is up to the task of running Windows 7 hardware and if you can get all necessary drivers from Did you run the Windows 7 upgrade advisor from

That being said: install a (new, other) empty hard disk to install Windows 7 on. Then you're sure it won't boot Windows XP and you can easily go back to Windows XP if it turns out Windows 7 isn't working as you wish.
Making an disk image, then fully erasing the disk instead of using another disk is an alternative.

You need to know that

You need to know that Microsoft never issued Windows 7 on USB or documented how to install from USB. I looked into that a month ago and the documented Microsoft way was from a Windows 7 bootable DVD. I'd go with the supported boot media next.

As to the USB, did you test if it boots on other PCs?
Many old PCs can't boot USB sticks. And some can't boot from today's larger sticks. Your machine, you have to know this or google it. There are dozens of that 3000 model so I can't know yours or what BIOS, which USB ports might boot, etc.

In other words, get back to how it was done in the beginning.

Dell does not support w7 on that machine.
If you do get it to install you might be in for a big headache trying to get it to function.

As mentioned have a fall back plan....clone/image
