Windows XP 64 bit and a new In Stall along side
 

Hi I cant load Unbutu from a new in stall along side windows XP 64 bit ? any help

What did you try ?
Did you boot from cd?
Did you try to install within windows?
Not telling us much to help you.

I just installed along side Xp 64 bit with download cd didnot do any yet but restart . restart restart and it just restarts in xp

As soon as the screen goes blank after the POST (hardware) messages, hit the <Shift> key - see if that gets the boot menu up.
If so we can give you some help to make it show permanently.

Did you boot from cd?
Did it ask if you wanted to install boot loader to MBR?

Boot
 

CD - Yes

MBR - Dont think so


??

If didn't install boot loader you can't boot linux.

If you got a message that Ubuntu was successfully installed and asking you to reboot, then your problem is most likely that mentioned above. You did not install the Ubuntu Grub2 bootloader to the master boot record and if you are still booting xp, the xp boot code is in the mbr. You can manually configure the xp install to boot Ubuntu or you can install the Ubuntu Grub2 on the master boot record. I think you can guess which would be easier?

See the link below, Section 12 in particular for several methods. I would suggest reading through this before doing anything:
