A boot problem

Well, i installed windows 8 first on hard disk 1, i used to boot to win 8 normally
Then i installed windows xp on hard disk 2,
Now i boot to win xp automatically, i don’t even see a dual boot screen
I want to use windows 8 once again
Any help?
Answer #1
Use native vhd boot http://blogs.technet.com/b/virtualization/archive/2009/05/14/native-vhd-support-in-windows-7.aspx
for the xp partition
Answer #2
Well, the problem is as follows;
I first installed win8 on one hard disk, and then win xp on the other.
I can only boot to xp!!!!!!!!
Using some of the utilities on hiren’s boot cd to make the partition of win8 bootable was not successful at all
;(
Answer #3
hiren’s boot cd is junk now that windows to go is here, Boot from the windows 8 installation media and use the tools on that this will involve killing the xp bootloader so youll have to go with native vhd boot afterwards.
