Dual boot - Windows 2000 then XP or other way

Hi techie pros,

can any one share how to install dual boot, I have some problem with win 2000 and every time only new installation works other one does not.

I have windows 2000 with sp4 in C drive, I installed windows XP sp2 in D drive. XP working fine but windows 2000 getting stuck while booting.

What I did was kept win xp cd in the cd-rom started pc, it asked me to press enter to boot from cd then followed installation steps, once done tested in XP login its working fine, and went back to win 2000 got stuck there.

I did not get problem with win 2000 prof(c drive) and win 2000 server(d drive) and also in other installation win 2000 prof(c drive) and win 2003 server(d drive).

Every time I'm getting problem with only win 2000 and XP in any drive any of these two ie first 2000 then xp or first xp then 2000 or c drive first d drive later or the other way. why cant these two windows can not go smoothly. Please share if some one installed with out problems.

My big problem:
unable to work win 2000 and XP in c and d drives.

After working fine with XP in d drive, I tried to repair win 2000 by choosing r option
it did not work, tried installing it again in C but that worked and again XP is gone. I'm able to work only with ONE but not TWO.

Is there any straight way, if not can i install XP in c and d drives.

Please share if some one installed with out problems. thx in advance.

Look up boot.ini in google. You just need two lines, one for W2K and one for XP, each pointing to the approproiate partition. What you are doing when you reinstall each OS is writing the boot.ini with just one line. This is a fairly good one http://mirror.href.com/thestarman/asm/mbr/bootini.htm

Do you really need to have a dual-boot ?

Would 2000 running in Virtual PC not do ?
