Error when installing 11.04 from USB

[Kom Sihon]

Hi buddies,I'm experiencing difficulties installing Ubuntu 11.04 on an HP Laptop originally running Windows7. I tried using CD, but it blocks somewhere and displays Kernel Panic, etc.
I then tried using the USB Key boot and created the Boot Disk with Ubuntu. But I have the following error when booting from the USB Key: Unknown keyword in configuration file. boot:
I downloaded the 32-bit version of Ubuntu, but the original system is a 64-bit one. Could that be the problem? or it is something else?
Thx for helping me.

Hi and welcome to the forums :-)

First check the integrity of the image to make sure it is good:

Second, I suggest you try putting the image on the USB stick with UNetbootin:
http://unetbootin.sourceforge.net/

I believe there is a bug in the USB creator on Ubuntu which causes this, but am not sure if this is the same one.

Either way, try UNetbootin.

Thx very much guy, it really seems unetbootin is better to create startup USB Disk. Now it boots normally from the key but there's another issue after few seconds: It looks like this

Cannot reserve MMIO region
[] mmio address 0x8f09d217 already in use

Any idea? I remind you that it is an AMD Processor previously running a 64-bit Windows 7. I'm tryin to install the 32-bit Ubuntu. Do you think that can be the problem?

It is all right to run a 32 bit Ubuntu on 64 bit hardware. In fact I recommend doing this, unless people have an absolute need for 64 bit.

Have you done a memory test from the live boot?

Trying 10.10 is also worth the while.
