Can't boot from cd

[ancientscribble]

Burned an Ubuntu 9.04 cd with at 1x speed. (I heard slower is better for this...)

Every time I boot up it goes straight to my choices of Vista and Windows 7 RC.

I've pressed F12 to let it know I want to boot from a CD.

And even just before doing this I booted from a Slackware DVD successfully...

I'm using a Thinkpad T60p with an Intel Core 2 duo, 2.0 GHz, 2.0 GB RAM

If anyone could help me to finally try out Ubuntu I'd appreciate it.

Did you checksum your downloaded .iso, and did you burn it as a disk image?

[ancientscribble]

md5sum my Ubuntu 9.04 Desktop i386 iso: ae339f196460ba16bbdfd12e1fcde2de

md5sum it's supposed to be according to list: 66fa77789c7b8ff63130e5d5a272d67b

I've been burning as ISOs with DVD Decrypter.

So it would seem that your download got corrupted. If the checksums do not match, it will never work.

You might try a torrent....

Yikes. I tried 2 different torrents but I get the same result.

How can it be possible that everything is corrupted?
I tried different mirrors at the Ubuntu site too.

Am I doing something wrong?

Is the i386 desktop version the one I should be trying?

Thanks for the help so far.

Didn't think I would need help just to get the CD to load...

Be sure you are running the checksums for the .iso you have downloaded. It is easy to get confused.

You can use the 64-bit version since you have a dual-core processor, but i386 will also work.
